<abstract> <p>Consumption of nine different natural resources has kept an increasing trend in Central African countries from 1970 to 2018. This study therefore, investigates the changes and major determinants that have driven the patterns of resource use in six Central African countries over almost fifty years. We used the logarithmic mean Divisia index (LMDI) method to quantitatively analyze different effects of technology, affluence and population associated with domestic material consumption (DMC) of Cameroon, Chad, Central African Republic, Equatorial Guinea, Democratic Republic of the Congo and Gabon from 1970 to 2018. We further subdivided the technological effect into technological intensity (DMC/energy) and energy intensity (energy/gross domestic product (GDP)) and conducted a four-factor LMDI analysis of Cameroon as a case study. The results highlight that decreased affluence during certain periods has slowed down DMC growth in four of six Central African countries except for Cameroon and Equatorial Guinea, while significant technology offset in Equatorial Guinea reduces DMC growth by 28%. Population remains the main positive driving factor of DMC growth, with the highest share in the Democratic Republic of the Congo. The case of Cameroon shows that technological intensity and energy intensity play different roles in changing DMC. This study confirms that the rising population and economic growth, combined with a gradual improvement in technology in the region are insufficient to reduce natural resource use. A stringent management plan of natural resources for Central African countries should focus on technological improvement while remaining balanced with the future demand for socioeconomic development in the coming decades.</p> </abstract>

In the light of linkages in various scales and targets, the complex and nuanced design of the sustainable development goals (SDG) raises more challenges in their implementation on the ground. This paper reviewed 25 food security indicators, proposed improvements to facilitate operationalization, and illustrated practical implementation. The research focused on three essential blind spots that arise from the potential interactions between sustainable food production, consumption, and domestic material consumption (DMC). Projection of latent structure regression was applied to link food security and sustainable development goals. Findings revealed that the key target in reducing trade-offs was the integration of DMC with sustainable food production and consumption. DMC was positively correlated with the creation of coherent SDG strategies and sustainable food security. Practical implications were discussed by highlighting how to achieve food security across contrasting development contexts and the challenges of addressing the links between targets and indicators within and beyond SDGs 2 and 12. The results are useful for setting a proper strategy for sustainable production and consumption that can improve the efficient use of resources in the eight Central European countries.

Full textAbstract:
Resource efficiency is a primary policy goal in many developing countries that are resources suppliers. This study performed a first try to explore the resource productivity and efficiency of an emerging world factory, Vietnam, by applying an improved economy-wide material flow analysis (MFA) integrated with a data envelopment analysis (DEA)-based Malmquist productivity index approach (MDEA). Resource flows from 1978 to 2017, and the corresponding utilization efficiency considering the unexpected environmental outputs, as well as productivity were explored in depth. The results highlighted a positive correlation between rapid growth among domestic material consumption (DMC), GDP per capita, and material intensity (DMC/capita) in Vietnam during the last four decades. Meanwhile, the resource productivity (USD/DMC) increased from 82.4 USD/ton to 125 USD/ton (2017), presenting a much slower pace than that of Japan and China. The IPAT-based decomposition analysis highlighted the contribution of rising affluence (94%) and population (21%) to the rapid growing DMC, while the technology factor (DMC/GDP) needed to be further enhanced. Finally, the total factor productivity, when comparing between Vietnam, China, South Korea, and Japan, showed that, on the one hand, the Vietnamese economy has strongly been changed in a positive direction with EFFCH 1.061 and TECHCH 1.046 during the last four decades. One the other hand, Vietnam is still material intensive and has low material productivity. Our analytical results recommend Vietnam to strengthen technology innovation and aim for efficiency enhancement through closely coordinated policies on sustainable resource consumption, carbon reduction, and economic growth, in line with the United Nations Sustainable Development Goals for 2030 (SDGs 2030).

Full textAbstract:
This study offers an in-depth analysis of the decoupling of economic growth from fossil fuel use in 141 countries over the last 25 years. The study is based on the Tapio decoupling approach, and two methods of measuring fossil fuel use, i.e., domestic material consumption (DMC) and material footprint (MF), are applied. Groups of countries with similar decoupling patterns are identified through the k-medoids method. Next, the relationship between these patterns and the level of countries’ development is examined. The results reveal that using different measures of fossil fuel use yields different processes of decoupling economic growth from fossil fuel use. In particular, when the DMC indicator is considered, relative decoupling is observed in most analysed cases. When the MF indicator is applied, the decoupling states of individual countries change more frequently. Finally, in highly developed countries, absolute decoupling is frequently observed, although only when the DMC indicator is used.

Full textAbstract:
The European Commission has established a Critical Raw Materials List (CRM) for the European Union (EU), which is subject to regular review and updating. CRMs are needed in many key industries such as automotive, steel, aerospace, renewable energy, etc. To address this issue, we studied publicly available data from databases developed by the EU for monitoring the progress of individual countries in key areas for the development of society. The paper analyzes indicators of import reliance, net additions to stock, domestic material consumption (DMC), resource productivity, and circular material use rate. Prospective products and technologies, in electromobility, digitalization, Industry 4.0, and energy transformation, are changing and increasing the demand for raw materials. The aim of this article is to look at the ways forward in order to use critical raw materials as efficiently as possible while at the same time ensuring the optimal economy of the countries. From the sources and databases of data available for the EU, we analyzed a number of variables and suggested options for future developments in the efficient use of critical raw materials. We defined what we believed to be the optimal management means in relation to critical raw materials and worked backwards to find a path to efficient use of critical raw materials.

Full textAbstract:
Abstract Research background: The fact that all resources are not infinite and the needs of society are steadily increasing, new ways of producing, consuming and waste disposal should be adopted. A circular economy as a modern alternative to a linear economy became one of the priorities of the European Union in order to create a modern, resource-efficient and competitive system. Purpose: The purpose of this article is to present the concept of a circular economy and the justification of its implementation based on a literature review. The article focuses on determining the factors of a circular economy and evaluating its importance in the Baltic States. In other words, the main aim of the article is to highlight the factors of a circular economy and assess its significance. Research methodology: A panel regression analysis was used in order to evaluate which indicator of the selected circular economy factors is the most important. Results: The survey reveals that waste electrical and electronic equipment has the most significant potential for increased circular material use rate in the Baltic States. All electrical and electronic equipment should be designed so that it would be possible to repair and reuse it to extend the product life cycle and reduce the carbon footprint. Reducing greenhouse gas emissions in conjunction with increasing the usage of renewable energy could increase resource productivity and domestic material consumption (DMC) and ensure Baltic States’ independence in the energy sector through offshore wind farms that have the region’s most considerable potential. Novelty: There is a lack of studies conducted in the Baltic States focused on circular economy development using panel data. Most of the previous studies were focused on the European Union as a whole or individual countries. This study presents a deeper analysis of circular economy development in the Baltic States.

"Do Tourism Activities and Urbanization Drive Material Consumption in the OECD Countries? A Quantile Regression Approach." Sustainability 13, no. 14 (July 12, 2021): 7742. http://dx.doi.org/10.3390/su13147742.
Full textAbstract:
The United Nations Sustainable Development Goals (UNSDGs) elaborately encompass a global goal for sustainable consumption and production (Goal 12: SDGs), thus providing potential drivers and/or pathways to attaining sustainable consumption. In view of this global goal, this study examined the role of real income per capita, urbanization and especially inbound tourism in domestic material consumption for the panel of OECD countries. The study is conducted for the period of 1995 to 2016 by employing the panel quantile approach. Interestingly, an inverted U-shaped relationship between outbound tourism and domestic material consumption is established across the quantiles, thus indicating that sustainable domestic consumption is achievable after a threshold of domestic material consumption is attained. In addition, achieving sustainable consumption through economic or income growth is a herculean task for the OECD countries because the current reality indicates that income growth triggers higher consumption of domestic materials. However, the results suggest that urbanization is a recipe for sustainable domestic consumption since there is a negative and significant relationship between the two parameters across the quantiles. Nevertheless, the study presents relevant policy for efficient material and resources utilization and that is suitable to drive the SDGs for 2030 and other country-specific sustainable ambitions.

Full textAbstract:
Metrics on resource productivity currently used by governments suggest that some developed countries have increased the use of natural resources at a slower rate than economic growth (relative decoupling) or have even managed to use fewer resources over time (absolute decoupling). Using the material footprint (MF), a consumption-based indicator of resource use, we find the contrary: Achievements in decoupling in advanced economies are smaller than reported or even nonexistent. We present a time series analysis of the MF of 186 countries and identify material flows associated with global production and consumption networks in unprecedented specificity. By calculating raw material equivalents of international trade, we demonstrate that countries’ use of nondomestic resources is, on average, about threefold larger than the physical quantity of traded goods. As wealth grows, countries tend to reduce their domestic portion of materials extraction through international trade, whereas the overall mass of material consumption generally increases. With every 10% increase in gross domestic product, the average national MF increases by 6%. Our findings call into question the sole use of current resource productivity indicators in policy making and suggest the necessity of an additional focus on consumption-based accounting for natural resource use.

Full textAbstract:
Recently, economists and environmental scientists have problematised households, showing that their reducing size in average number of inhabitants has implications for environmental sustainability due to losses in economies of scale. Findings suggest that resources are shared better when people live together. This article analyses this common domestic consumption, drawing on literature about households, sharing and sustainable consumption. It is argued that multiple-person households apportion the resources involved in supplying practices through three modes of sharing: successive sharing, simultaneous sharing and shared/divided work. These are underpinned and enabled by standard material arrangements of households, in which a minimum of certain goods and services are available to residents regardless of number. Exemplifying the perspective, I examine recent survey data relating to meals and domestic laundry, two sociologically significant and resource-intensive spheres of domestic activity, paying attention to differences across one-person and multiple-person households. Modes of sharing, it is argued, also surfeit the domestic sphere, with market, state and household infrastructures playing contextually variable roles in provisioning goods and services among populations.

Full textAbstract:
Since the relationship between the supply and demand of fossil fuels is on edge in the long run, the contradiction between the economic growth and limited resources will hinder the sustainable development of the Chinese society. This paper aims to analyze the input of fossil fuels in China during 2000–2010 via the material flow analysis (MFA) that takes hidden flows into account. With coal, oil, and natural gas quantified by MFA, three indexes, consumption and supply ratio (C/S ratio), resource consumption intensity (RCI), and fossil fuels productivity (FFP), are proposed to reflect the interactions between population, GDP, and fossil fuels. The results indicated that in the past 11 years, China’s requirement for fossil fuels has been increasing continuously because of the growing mine productivity in domestic areas, which also leads to a single energy consumption structure as well as excessive dependence on the domestic exploitation. It is advisable to control the fossil fuels consumption by energy recycling and new energy facilities’ popularization in order to lead a sustainable access to nonrenewable resources and decrease the soaring carbon emissions.

Full textAbstract:
Drawing upon narrative and visual ethnographic data collected from households in the UK, this article explores the material and emotional geographies of the domestic kitchen. Acknowledging that emotions are dynamically related and co-constitutive of place, rather than presenting the kitchen as a simple backdrop against which domestic life is played out, the article illustrates how decisions regarding the design and layout of the kitchen and the consumption of material artefacts are central to the negotiation and doing of relationships and accomplishment of domestic life. Based on fieldwork in northern England, the article examines the affective potential of domestic space and its material culture, exploring how individuals are embodied in the fabric and layout of domestic space, and how memories may be materialized in their absence.

The purpose of the article is to carry out a comprehensive analysis of the raw material market of wine products, production and distribution of wine through sales channels, opportunities and restrictions on the sale of wine in domestic and foreign markets; to determine the state and potential volumes of wine consumption in Ukraine; to elaborate ways and directions of development of production and consumer potential of the domestic wine market to ensure supply and demand formation. Research methods includes an abstract-logical method to substantiate the production and consumer potential of the market; analysis and synthesis – to establish the size of the area, yield, gross harvest, processing of grapes into wine materials, range of products, geography of export and import and wine consumption; economical and statistical and balance methods – for identifying trends and patterns of production and factors influencing the market of wine products, imbalances in the production and consumption of wine in the domestic market; comparative and calculation-constructive methods – to compare the levels of wine consumption in Ukraine and EU countries and substantiation of the consumer potential of the wine market in Ukraine; standard-cost method - for determining the amount of investment in the raw material base of the wine industry to develop production capacity and ensure supply in the wine market. Research results. Analysis of the market dynamics in the segments of grape growing and processing, the nomenclature of production, distribution and consumption of wine showed the discrepancy between the supply of raw materials on the market for loading the capacity of wineries, accompanied by the filling the domestic market with imported products. The ratio of wine exports to imports, production volumes to exports and imports, the share of domestic production and imports in the consumption fund and per capita has been established. The capacity of the domestic market for wine consumption in Ukraine at the level of European countries and the amount of investment to ensure its supply of wine products is determined. The ways and directions of development of production and consumer potential of the domestic wine market are outlined. Scientific novelty. The disproportions in the production and consumption of wine in the domestic market, the differences in the consumption of wine per capita in Ukraine and European countries are grounded. The production and consumer potentials of the domestic wine market have been determined. The volumes of investments, ways and directions of development of the production and consumer potential of the market for the interaction of supply and demand have been established. Practical significance. The investigated trends in the development of the production and consumer potential of the wine market serve as a guideline for making rational management decisions on the choice of ways and directions for increasing production and domestic consumption of products of the wine industry.

Full textAbstract:
The concept of circular economy (CE) has become popular in the last decade: both decision-makers and businesses are looking for alternative solutions replacing the present economic model. Official governmental documents have been selected for introducing Visegrad countries’ (V4) initiatives and monitoring the progress toward a transition to a circular economy. Based on selected material flow and resource productivity (RP) indicators, the study compares the regional differences among Visegrad countries. The current performances of the V4 in the implementation of the circular economic model are below the EU average. Moreover, it is noticeable that the dynamics of the changes of each indicator is more positive than on average in the EU, however, only moderate relative decoupling of domestic material (DMC) from GDP has occurred. When comparing individual countries, the wide range of the policy measures taken by V4 countries to support the transition to a circular economy can be considered promising. Despite the different characteristics of Visegrad countries, they show similar performances that are rather close to each other and incrementally approach to the EU average.

Four seasons of excavation at the Santa Isabel site on the shore of Lake Nicaragua have recovered an extensive assemblage of material remains relating to Early Postclassic period (A.D. 800–1250) domestic practice. This paper reports initial project results, specifically relating to themes of architecture, foodways, specialized production, and belief systems. Exceptional preservation of organic materials such as faunal and botanical remains, as well as bone tools, permits an expansive description of the material culture relating to household level consumption. Through the intensive coverage of 5 ha of the site center, including 10 house mounds, we see that intra-site variation also reflects community organization. Finally, Santa Isabel presents potential for inferring cultural relationships between central Mexico (based on ethnohistorical accounts) and Greater Nicoya.

Full textAbstract:
The main objective of the paper is to highlight Romania’s perspectives on the transition process towards the circular economy, in respect with the tendencies registered at the level of the European Union. To this end, our methodology involved the selection of four indicators, each one being viewed as representative for one area of interest specified in the circular economy monitoring framework established by the European Commission, namely: Generation of waste excluding major mineral wastes per domestic material consumption; Recycling rate of municipal waste; Circular material use rate; Gross investment in tangible goods—percentage of gross domestic product. On the basis of data series provided by the Eurostat database, our study employed a quantitative approach, by using the econometric analysis of time series. For each selected indicator, time series-specific approximation and prediction models were constructed; against this background, we were able to reveal accurate forecasts of the analysed variables, with respect to different time horizons. Detailed analysis of the data series resulting from the research proved that on the long run, there are favourable premises for improving Romania’s performance in adopting the circular economic model, on the basis of low values for the indicator “Generation of waste excluding major mineral wastes per domestic material consumption”, of an ascending trend for the indicator ”Circular material use rate” and of maintaining the values of the “Gross investment in tangible goods—percentage of gross domestic product” indicator above the EU-27 average.

Energy and food security are two key national policies and agenda of Thailand. The Department of Alternative Energy Development and Efficiency (DEDE), Ministry of Energy has modified a 15-year (2008-2021) Alternative Energy Development Plan (AEDP). According to the modified AEDP, the share of renewable and alternative energy consumption should increase to 25% by 2021. The latest policy aims to promote the biodiesel consumption and production by 5.97 million liters/day within 2021, up from its previous plan of 4.50 million liters/day while nowadays production capacity is 1.62 million liters/day. The current and anticipated production of biodiesel require raw materials, notably crude palm oil (CPO) from oil palm plantations. This paper presents a feasibility study, with respect to the AEDP plan, for biodiesel production by using domestic fresh fruit oil palm as a raw material. Demand and supply are analyzed based on statistical modeling and forecasting techniques, as well as GIS spatial analysis. The results show that the domestic CPO consumption for cooking palm oil will be 1.02 million tons/year, while biodiesel production will be 1.67 million tons/year in 2021. This corresponds to an oil palm plantation area of 11,152 km2 in 2021. Based on GIS spatial analysis along with land-use database and other relevant databases, it was found that the suitable area for palm oil plantation in Thailand is 14,639 km2, which is sufficient for domestic demand and consumption. The suitable area consists of 9,664 km2 for quite suitable and 4,975 km2 for medium suitable. However, the government should provide the guidelines, along with pro-active and supportive policies for worst case scenarios, e.g. drought and flood leading to the insufficient raw material, in order to reduce the negative impacts of biodiesel production for domestic demand and consumption.

Full textAbstract:
Understanding the drivers of energy and material flows of cities is important for addressing global environmental challenges. Accessing, sharing, and managing energy and material resources is particularly critical for megacities, which face enormous social stresses because of their sheer size and complexity. Here we quantify the energy and material flows through the world’s 27 megacities with populations greater than 10 million people as of 2010. Collectively the resource flows through megacities are largely consistent with scaling laws established in the emerging science of cities. Correlations are established for electricity consumption, heating and industrial fuel use, ground transportation energy use, water consumption, waste generation, and steel production in terms of heating-degree-days, urban form, economic activity, and population growth. The results help identify megacities exhibiting high and low levels of consumption and those making efficient use of resources. The correlation between per capita electricity use and urbanized area per capita is shown to be a consequence of gross building floor area per capita, which is found to increase for lower-density cities. Many of the megacities are growing rapidly in population but are growing even faster in terms of gross domestic product (GDP) and energy use. In the decade from 2001–2011, electricity use and ground transportation fuel use in megacities grew at approximately half the rate of GDP growth.

The annual output of domestic waste has exceeded 400 million tons in China since 2016, which causes an urgent demand on harmless disposal in the current rapid process of urbanization. Compared with traditional disposal means (e.g. incineration and landfill), co-processing with cement production seems to be a better chose to meet the requirements of domestic waste treatment (i.e. harmless, volume reduction, waste utilization). However, co-processing technology also has some negative impact (e.g. extra energy consumption for pretreatment of domestic waste), so the environmental feasibility of domestic waste co-processing in cement kiln should be verified. In this paper, the influences caused by domestic waste co-processing on the cement clinker products including resource/energy consumption, as well as the pollutant emissions were quantify based on the investigation of typical plants in China. Moreover, the environment impact between landfill treatment and co-processing scenario were compared using life cycle assessment (LCA) method. The result shows that the energy consumption and CO2 emission per ton cement clinker production increased by 3.6% and 0.8% after co-process domestic waste, respectively. Furthermore, compared with sanitary landfill treatment, the co-processing in cement kiln will increase the impact of FFP, but reduce GWP and HTP impacts, especially significantly decrease the impact of LOP and SOP, bring in a good beneficial on material saving and energy saving.

Freezer is one of the electrical components that can be found in any building. Like any electrical appliance domestic freezer consumes a significant amount of energy during its working time. During recent decades a lot of solutions have been found to reduce this energy consumption. One of the most usable and appropriate ones is implementation of phase change material (PCM) in a Cold Thermal Energy Storage (CTES) system which can be installed in a household freezers. In this paper numerical investigation of using CTES system in a domestic freezer in order to diminish energy consumption during pick hours (18-22:30), is studied. Regard to the temperature ranges of the freezer, NaCl-H2O is used as a PCM in the CTES system. In a distinct period of time, a large amount of cold thermal energy in latent heat form is stored at low temperature in the PCM, and it is released in the freezer’s cabin when the compressor is off. Accordingly, numerical modeling and simulation using Computational Fluid Dynamics (CFD) software on charging and discharging cycle of PCM are done to measure cold storage period and amount of saved energy. The results reveal that using CTES could keep the freezer in the standard thermal condition without using a compressor, for 4.5 hours. These results show that if the PCM used in CTES system for a year, it could reduce energy, fossil fuel consumption and CO2 emission up to 45.7 kWh, 13.7 liters and 32.0 kg, respectively.

Regard to the temperature ranges of the freezer, NaCl-H2O is used as a PCM in the CTES system. In a distinct period of time, a large amount of cold thermal energy in latent heat form is stored at low temperature in the PCM, and it is released in the freezer’s cabin when the compressor is off. Accordingly, numerical modeling and simulation using Computational Fluid Dynamics (CFD) software on charging and discharging cycle of PCM are done to measure cold storage period and amount of saved energy. The results reveal that using CTES could keep the freezer in the standard thermal condition without using a compressor, for 4.5 hours. These results show that if the PCM used in CTES system for a year, it could reduce energy, fossil fuel consumption and CO2 emission up to 45.7 kWh, 13.7 liters and 32.0 kg, respectively.

Abstract The main purpose of the work is to build models for forecasting energy consumption. With the goal in mind, the problems of building energy consumption models are solved using the Sugeno fuzzy knowledge base and the regression model. The presentation of the material is carried out on the example of constructing a fuzzy model of the dependence of energy consumption on the number of population and gross domestic product (GDP). It is necessary to find out how energy consumption depends on the population, GDP, and the price of oil. The synthesized fuzzy model will have one output and three inputs.

Reducing material flows and their associated environmental impacts substantially contributes to moving toward a more sustainable society. Both individual consumption behavior and governmental regulations play a crucial role in reaching sustainability goals. In this article, we present a Material Flow Analysis combined with a simplified Life Cycle Assessment of the Swiss economy. Results were linked to an analysis of consumption patterns. This allowed us to evaluate the direct influence of consumer behavior on national greenhouse gas emissions using a consumption-based approach and the quantification of the range of these emissions from different lifestyles. We conclude that the consumer has a direct influence on slightly more than 50% of the greenhouse gas emissions generated by the Domestic Material Consumption. If everybody were to behave like the 20% of the population with the most climate-friendly behavior, emissions would decrease by merely 16%. Cooperation between stakeholders at all levels of society is therefore needed. This study provides a contribution to decreasing material and energy consumption and defining possible future pathways with the final aim to bring anthropogenic greenhouse gas emissions down to zero in Switzerland.

There is ample evidence that an unabated growth in material consumption is likely to pass the earth system's source and sink capacities. In the face of limited resources, distributional questions increasingly gain importance. Material flow accounting is a methodological tool to trace biophysical patterns of disproportionate resource consumption across countries and the debt towards the environment, other parts of the world, and towards future generations through the excessive consumption of natural resources. At the core of this article, we address different developments of material use for individual countries and world regions from 1950 to 2010. During this phase, fossil fuel-based industrialization triggered an unprecedented growth in material consumption, mainly in the wealthy world regions of Europe, Australia, North America, and partly in the countries of the former Soviet Union, while low resource consumption persists in other regions. We thus calculated cumulative resource use from 1950 to 2010 to show the extent of this wealth built up upon countries' own resources, or through imports from other countries or world regions. We use the degree of net-import dependency of individual countries as a proxy for the ecological debt, and relate it to the domestic resource extraction in a country. Our observations show that there was a highly uneven distribution of resource extraction and use in the 60 years analyzed, which has important implications for future global resource policies.Keywords: Ecological debt, material flow accounting, international trade, global resource useRésuméIl

Environmental concerns push for a reduction in greenhouse gas emissions and technologies with a low carbon footprint. In the transportation sector, this drives the transition toward electric vehicles (EVs), which are nowadays mainly based on lithium-ion batteries (LIBs). As the number of produced EVs is rapidly growing, a large amount of waste batteries is expected in the future. Recycling seems to be one of the most promising end-of-life (EOL) methods; it reduces raw material consumption in battery production and the environmental burden. Thus, this work introduces a comprehensive pre-recycling material characterization of waste nickel-manganese-cobalt (NMC) LIB cells from a fully electric battery electric vehicle (BEV), which represents a basis for cost-effective and environmentally friendly recycling focusing on the efficiency of the implemented technique. The composition of the NCM 622 battery cell was determined; it included a LiNi0.6Co0.2Mn0.2O2 spinel on a 15 μm Al-based current collector (cathode), a graphite layer on 60 μm copper foil (anode), 25 μm PE/PVDF polymer separator, and a LiPF6 salt electrolyte with a 1:3 ratio in primary solvents DMC and DEC. The performed research was based on a series of X-ray, infrared (IR) measurements, gas chromatography–mass spectrometry (GC-MS), and inductively coupled plasma–optical emission spectrometry (ICP-OES) characterization of an aqueous solution with dissolved electrolytes. These results will be used in subsequent works devoted to optimizing the most suitable recycling technique considering the environmental and economic perspectives.

Full textAbstract:
Abstract In a Swiss case study of the ReCO2st research project, hot water optimization demonstrated a high potential for energy savings with low investment costs. The optimization started with the end user to reduce first hot water consumption. Energy-efficient showerheads and faucets reduced hot water consumption by 10 to 25%, notably from 65.2 [l/p.day] to 48 [l/p.day] for the period of September to October 2019. A multi-criteria selection of showerheads involved end users considering other qualitative aspects like rinsing efficiency, overall feel of use, noise, and material robustness. Strict control of pipe and storing tank insulation reduced storage and distribution losses. Day and night storage temperature setpoints, water recirculation time, switching off this process after 11:00 p.m., temperature differential of start and stop loading setpoints, creating long loading cycles, ensure that the pipes are not always hot. Reducing Legionella cycles at 60° to once a day avoided the need for continuous high temperatures. The combination of all these soft measures in the Swiss case study resulted in a reduction of energy consumption for hot water of 20-30%. This is equivalent to the installation of expensive solar panels for hot water. A detailed two-year monitoring of the building's hot water consumption shows the contribution of each optimization measure. The encouraging results show that without perfect control of the entire process, it is impossible to avoid a performance gap between planned and actual energy consumption.

Rice is one of the main crops of strategic importance. Rice consumption in Kazakhstan is increasing compared to other cereals and reaches more than 65 %. Today, due to the increase in imports of rice cereals, it seems relevant to develop rice production, increase its competitiveness, and create domestic rice varieties with improved nutritional and culinary qualities. A key factor in determining the quality of rice is the percentage of amylose in the starch of the rice grain. In this regard, this work is devoted to the search for donors of the trait “high amylose content” among varieties and lines of domestic and foreign breeding in the rice collection of the RSE on the REM “Institute of Plant Biology and Biotechnology” (RSE on the REM “IPBB”). Screening of 172 foreign and domestic varieties and lines of rice for amylose content made it possible to identify 9 high-amylose variety samples. Among them one domestic ancient variety of Kazakh selection K3077 Kazakhi was found, which can serve as a donor of the trait “high amylose content”. Because of the climatic conditions of Kazakhstan and the long growing season, only six foreign varieties and lines were selected: Mavr (26.8 %), Taibonet (25.4 %), Parity (27, 0 %), K3612 Kara-Kyltyk (25.0 %), K3077 Kazakhs (25.1 %), and Solnechny (25.4 %). The selected varieties and lines of rice with a high content of amylose will be used as donors of the “high amylose content” trait for rice breeding.

This paper constructs a two-tier structural decomposition analysis model to decompose the change of energy use during 1987 and 2010 into 11 factors, and analyze the results of sub-periods. The results show that the scale and products’ structure of domestic final demand, the scale of exports, imports substitution, the structure and the input technology of material promoted the energy in the whole period. However, the intensity of energy, the products structure of exports , the structure and technology change of energy input reduced the energy consumption.

The implementation of thermal energy storage systems using phase change materials to support the integration of renewable energies is a key element that allows reducing the energy consumption in buildings by increasing self-consumption and system efficiency. The selection of the most suitable phase change material is an important part of the successful implementation of the thermal energy storage system. The aim of this paper is to present the methodology used to assess the suitability of potential phase change materials to be used in two innovative energy storage systems, one of them being mainly intended to provide cooling, while the other provides heating and domestic hot water to residential buildings. The selection methodology relies on a qualitative decision matrix, which uses some common features of phase change materials to assign an overall score to each material that should allow comparing the different options. Experimental characterization of the best candidates was also performed to help in making a final decision. The results indicate some of the most suitable candidates for both systems, with RT4 being the most promising commercial phase change material for the system designed to provide cooling, while for the system designed to provide heating and domestic hot water, the most promising candidate is RT64HC, another commercial product.

ABSTRACTThis paper examines the new styles of houses under construction in contemporary Tanzania and suggests that they can be understood as the material manifestation of middle class growth. Through an examination of the architecture, interior decor and compound space in a sample of these new houses in urban Dar es Salaam and rural Kilimanjaro, the paper identifies four domestic aesthetics: the respectable house, the locally aspirant house, the globally aspirant house and the minimalist house, each of which map on to ideas aboutujamaa, liberalisation and the consumption of global consumer goods in distinct ways. The paper argues that these different domestic aesthetics demonstrate intra-class differences, and in particular the emergence of a new middle class.

Relevance. Water is one of the most important elements of the biosphere on the quality of which largely depends on human health. The quality of water in surface water bodies is one of the decisive factors in the sanitary and epidemiological well-being of the population.
Objective of our study was a scientific substantiation of the maximum allowable concentration of cyflufenamid in water of households-drinking and cultural-domestic appointments reservoirs.
Materials and methods. We conducted a laboratory hygienic experiment using organoleptic, sanitary-chemical, sanitary-microbiological methods of analysis. The data obtained in the experiment were processed by the methods of variation statistics.
Results. The investigated solutions with different cyflufenamid concentrations had high transparency (>30 cm), their colority did not differ significantly from the control tap water. The influence of cyflufenamid on the intensity of the process of biochemical oxygen consumption, changes in the number of saprophytic microflora, the dynamics of mineralization of nitrogen-containing substances, the level of dissolved oxygen in water and the changes in the active reaction of the medium (pH) at its concentrations from 0,005 to 0,5 mg/dm3 were studied. It was noted that the process of mineralization of organic substances in water in the presence of cyflufenamid had a logical sequence of stages. The process of mineralization ended until the 30th day of observation.
Conclusion. The maximum allowable concentration of cyflufenamid in water households-drinking and cultural-domestic appointments reservoirs has been established at the level of 0,005 mg/ m3 according to general sanitary limiting index.

This study identifies the barriers to sustainable consumption and measures the discriminating power of these barriers between groups having significant differences in their energy conservation behaviour. By analysing the response of 321 consumers to questionnaire survey in India, results reveal that belief in material growth is found to be the most important factor associated with the energy conservation behaviour across levels (grey, grey-green and green energy consumers). However, belief in technology is negatively associated with energy conservation efforts to all consumers. However, cynicism does not relate to energy conservation efforts. The results are significant to the agencies designing energy conservation campaigns aimed at modifying energy consumption behaviour of domestic consumers.

As a strategic emerging mineral resource, lithium is widely used in new energy, new materials and other emerging industries. There exists a changing trend of the material flow, consumption and evolution of lithium resources in the market. Thus, this research constructed a material flow analysis system for lithium resources based on the trade correlation of the whole life cycle. The study used the material flow analysis method to analyze the supply, flow and stock of lithium resources in China from 2007 to 2020. The research shows that during that timeframe, China’s cumulative consumption of lithium resources equivalent to lithium carbonate reached 309.9348 kiloton (kt). The consumption of lithium in traditional and lithium electric fields increased from 14.3653 kt and 8.08228 kt in 2007 to 49.53125 kt and 90.75866 kt in 2020, respectively. From 2007 to 2011, the consumption of lithium in the traditional sector was greater than that in the lithium electric sector. From 2012 to 2020, with the innovation of network technology and the boom in the New energy vehicles (NEV) market, the market for consumer lithium and power lithium grew rapidly, and the field of lithium with power batteries as the main driving force gradually became the major contributor to the consumption of lithium resources. With the rapid increase in the consumption demand for lithium resources, the supply structure of lithium resources in China has changed from domestic supply to international import. The external dependence of lithium resources has increased from 29.74% in 2007 to 70.75% in 2020. With increasing lithium consumption, the storage of lithium batteries increased from 20.69721 kt in 2007 to 341.6322 kt in 2020. At the same time, the scrap volume of lithium batteries increased rapidly, but the recycling volume of lithium resources was far lower than the scrap volume. The resource recycling potential is huge, and there is still a lot of room for the development of the sequential utilization of waste lithium-ion batteries.

As a driving force of economic growth, China’s export was affected by global economic crisis during 2008~2010. This paper aims to assess the impact of economic crisis on China’s energy consumption during the crisis. Contributions of energy efficiency, domestic final use, exports and imports to energy consumption change were clarified using methodology involves structural decomposition analysis based on input-output price model. In 2009, exports of energy-related and raw material sectors were seriously impacted by economic crisis, with energy use dramatically decreased. However, economic stimulus plan implemented by central government provided a great boost to energy consumption growth. According to the study, quantity and structural adjustment of export is one of the important ways to reduce energy consumption in a short time. But in a long term, consumption control and energy efficiency improvement are unsubstitutable.

As part of the European Green Deal, the European Commission recently launched the project “New European Bauhaus of the 21st Century” to promote climate-neutral, affordable, and creative design approaches and transform the built environment towards sustainability. Based on a forecasting and backcasting approach, we developed three sets of measures containing eighteen individual measures, with the overall aim of reducing the consumption of mineral raw materials in line with the sustainability strategies (consistency, efficiency, and sufficiency) from exploration through material processing, to semi-finished product production. The developed measures address in detail the reduction of primary raw material consumption, the increased use of secondary raw materials, and the intensification of access to important domestic raw material sources, as well as the efficiency and productivity progression of the Austrian raw material industry. The implementation of the measures will raise the transparency and traceability of raw material routes, material flows, and supply chains through improved and comprehensive data collection and processing. The developed measures were handed over to the Austrian Federal Government in February 2022 to push the achievement of Sustainable Development Goal (SDG) 12 in Austria.

Film consumption has changed dramatically in recent decades. The rise of the multiplex has reconfigured the public experience of cinema. At the same time, movie viewing has grown exponentially in domestic and mobile spheres, driven by increasingly flexible access to content and the diversity of screens this material can now be delivered to. While the history of movie watching in theatres has been relatively well traversed, the more recent and highly popular practice of viewing outside cinemas remains significantly under theorised. This article takes up the issue of this critical neglect. It suggests that the practice of watching movies needs to be conceptualised in more integrated manner and that theories successfully applied to understanding digital, Internet and mobile media may be considered equally relevant to film.

The biofilm formation potential of a drinking water supply system is related to the chemical, microbiological and hydrodynamic characteristics of water, and to the pipe materials in contact with water flow. The goals of this study were: to determine the biofilm dynamics in a model of four drinking water installations, to simulate daily household water consumption; to compare the biofilms developed on different polymer pipe materials and their influence on bacteriological water quality. The results demonstrated that bacterial density of biofilms depended on pipe material type and was influenced by water temperature. The biofilms on polyvinylchloride chlorinated and polyethylene materials had higher bacterial density than biofilms on polypropylene (PP) brands. The effect of the materials, and respectively the biofilms, on drinking water quality was stronger in the overnight stagnation periods, especially during the initial weeks of model operation, than in periods of water consumption. Heterotrophic plate count (HPC) in stagnant or in flowing waters and water temperature followed a similar curve pattern, demonstrating significant seasonal variations. In summer, the HPC values of stagnant waters were raised up to seven times higher than in winter and those of the outlet waters (during the consumption periods) were raised up to four times.

Malaysian low grade iron ore is unsuitable as raw material for domestic iron making due to high energy consumption which correspond to low iron content. The present agricultural residues from domestic palm oil industry are attractive proposition as energy source for iron making. This work describes the use of ash produced from pyrolysis of palm oil Empty Fruit Bunch (EFB) to magnetize the low grade iron ore. A briquette composite of iron ore and ash is subjected to reduction process using an electric tube furnace under argon atmosphere at 873K and 1073K. The ore was successfully magnetized through reduction process as carbon in EFB ash act as reductant. The results showed that the reduction degree was greatly enhanced with increasing of temperature and time. The significant phase changes of iron ore from a non-magnetic material of goethite to a strong magnetic material of magnetite was detected in XRD patterns. The process indicated that substitution of coal with EFB ash as an energy source has a potential in replacing fossil fuel by magnetizining the iron ore as well as encourage waste management control.

Sociological contributions to debates surrounding sustainable consumption have presented strong critiques of methodological individualism and technological determinism. Drawing from a range of sociological insights from the fields of consumption, everyday life and science and technology studies, these critiques emphasize the recursivity between (a) everyday performances and object use, and (b) how those performances are socially ordered. Empirical studies have, however, been criticized as being descriptive of micro-level phenomena to the exclusion of explanations of processes of reproduction or change. Developing a methodological approach that examines sequences of activities this article explores different forms of coordination (activity, inter-personal and material) that condition the temporal and material flows of laundry practices. Doing so produces an analysis that de-centres technologies and individual performances, allowing for the identification of mechanisms that order the practice of laundry at the personal, household and societal levels. These are: social relations; cultural conventions; domestic materiality; and institutionalized temporal rhythms. In conclusion, we suggest that addressing such mechanisms offers fruitful avenues for fostering more sustainable consumption, compared to dominant approaches that are founded within ‘deficit models’ of action.

Full textAbstract:
Apartment buildings in Korea have adopted underfloor heating systems using web construction methods based on concrete and hot water systems. However, since such systems consume significant amounts of energy for heating owing to their low thermal storage performance, it is necessary to develop a new system that can minimize energy consumption by improving concrete thermal storage performance. This study proposes a phase-change material (PCM) underfloor heating system to reduce energy consumption in apartment buildings. An optimal design for a PCM underfloor heating system is proposed, and thermal storage performance of the proposed system is evaluated experimentally. The temperature range of the PCM for underfloor heating is also calculated considering the proposed design and comfortable heating conditions for domestic apartment buildings. Results indicate that a PCM underfloor heating system can be constructed in the following order: (1) a 210 mm concrete slab, (2) a 20 mm cushioning material, (3) 40 mm of mortar including a 10 mm PCM thermal storage container, and (4) 40 mm of finishing mortar including wire mesh and hot water pipes. The temperature range of the PCM used for underfloor heating in domestic apartment buildings is 32–45°C. Experimental tests reveal that thermal storage performance of underfloor heating systems that apply 35, 37, 41, and 44°C as representative PCM temperatures is superior to existing systems.
