Abstract The Ministry of Environment and Urbanization (MoEU) initiated an important project, ‘Reuse of Treated Wastewater in Turkey’, in 2017. With this project, all wastewater treatment plants (WWTPs) were investigated to determine wastewater reuse purposes for the first time. The results obtained from this project were that although there are 1,015 existing WWTPs, only 15 of them realized wastewater reuse. In 2017, the total volume of reused treated wastewater in Turkey amounted to 29.6 million m3/year, accounting for 0.78% of the treated urban wastewater. With the present water potential and sectoral water use rates, Turkey should make key administrative and technical regulations in the coming years for water reuse. This paper aims to give an overview of wastewater reuse activities from present status to future potential in Turkey and the opportunities and challenges in expanding water reuse. The status of WWTPs, treatment processes and their compliance with the WWTPs where reuse is carried out in Turkey are evaluated in this study. The realization of the planned goals and challenges are discussed after regulatory changes in Turkey for reclaimed wastewater and reuse targets for 2023.

In New York City (NYC), the aspiring target of zero waste to landfills is robustly engaging the often poorly understood solid waste management technique of reuse. The reuse activities occurring in NYC are reported, accounting for the quantities of reuse of various products, such as furniture, appliances and automobile accessories, amongst others. The quantities of products are translated to reuse mass and net CO2-eq emissions saved as a consequence of reuse. This quantitative assessment employs the Reuse Impact Calculator (RIC), based on the Waste Reduction Model (WARM). The RIC is a novel calculator used to quantitatively assess the environmental impact of material reuse. It uses the information about the material to be reused from the WARM database and estimates the emissions and energy savings based on the product’s final destination, that is, reuse, landfill, recycle or composting. A close monitoring of reuse activities in NYC shows 45 × 106 kg of reuse occurring for different products that would otherwise be directed to landfills. The net emissions reduced annually by reuse is approximately 122 × 106 kg of CO2-eq. This article compares the NYC reuse activities with that occurring in some select cities of the world. It is shown that the maximum recycle potential is saturated at 66%, and only auxiliary strategies like reuse can achieve the zero waste to landfill ambitions. Furthermore, this work discusses the role of reuse in the circular economy, wherein the resource utilization is maximized by increasing the shelf life of the product, and thereby enabling a maximum reuse potential.

Texto completoResumen
Due to water scarcity, which is worsening due to climate change, rural areas often face the challenge of rural exoduses. Limited water resources restrict local farmers as the opportunities for cultivation in the fields are reduced. This makes rural areas increasingly unattractive. To strengthen rural areas, sustainable water management with a focus on water-reuse is required. Since treated wastewater is a daily resource with calculable quantities available, reused water can contribute to the sustainable strengthening of a region. Therefore, an analysis of water-reuse potentials must be conducted to develop a water-reuse concept and thus increase the application of reused water. For this purpose, a case study of Wuwei as a rural and water-scarce region in China was chosen. By using a geoinformation system, the unfulfilled water-reuse potential can be identified by intersecting the results of the analysis regarding the current water supply and disposal situation with spatial and regional information, such as population data. Hence, the study presents the potential to increase wastewater treatment and water-reuse for, e.g., agricultural irrigation. It is shown that, in the best case, reused water can be increased from 5479 m3 per day to 207,461 m3 per day. Resource efficiency can be further increased by combining water-reuse concepts with land-use strategies adapted to climate change. This will ensure a more sustainable water supply in the future.

Texto completoResumen
Due to water resource shortage and socio-economic development within twenty years, China faces serious problems of water supply and water pollution. Several criteria and suitable reclamation processes related to water reuse have been created in China, which are helpful to improve the situation of water scarcity. In the future, reclaimed municipal wastewater reuse will mainly be developed for urban and industrial use. Potential supply quantity of reclaimed water, quality of reclaimed water, and reclamation cost are favorable to potential reuses. Based on further public environmental education, on a relevant development of national and local standards for reclaimed water quality, and on an increase of sanitary rate, more and more planned reclaimed water reuse projects would be expected in China.

Treated wastewater is one of the potential water resources in especially arid and semi arid regions. Overall, Turkey is not poor in terms of water sources. However, due to distribution of water in time and in space water shortage is felt. Wastewater reuse potential is especially high during summer months for agricultural and recreational purposes. In coastal areas of Turkey treated wastewaters from the coastal settlements are reused to irrigate the green areas and parks. Surplus effluents are discharged into the sea by use of marine outfall pipes. Extended aeration type of activated sludge processes followed by chlorination is the most common form of the treatment. Agricultural reuse is encouraged in inland rural regions. Simple wastewater treatment methods such as stabilization ponds are popular in rural areas. Water quality standards regulating irrigational wastewater reuse are recently set in Turkey. Guidelines given by World Health Organization (WHO) are generally adopted except the limits for the intestinal nematodes and the residual chlorine. Irrigational reuse standards as well as the degree of the treatment have to be revised based on the local experiences. Assurance of a given effluent quality is one of the major problems in management of the wastewater reuse in rural areas. Local examples are presented to illustrate this point.

Texto completoResumen
Abstract Water availability is facing crisis throughout the world because of various factors viz., population growth, climate change, and rapid urbanization, leading to the requirement of treated wastewater as an additional source of water supply. However, the actual amount of wastewater that may be reused depends on many factors such as water demand, availability, cost and social acceptability, etc. In this study, a linear programming model has been developed to identify the amount of treated wastewater that may be used for various applications subject to water availability and demand constraints, taking Delhi city as a case study. The results suggest that wastewater reuse has the maximum potential in agriculture and landscape irrigation use followed by domestic and industrial applications. The framework developed in the study provides useful information for integrated planning and management of the reuse of wastewater in order to augment the existing water supply. It may be modified and used for the estimation of wastewater reuse potential in other areas with similar conditions.

Texto completoResumen
Only 3.4% of total water use in the Bangkok Metropolitan area is reused treated sewage. This study anticipates that further treated-sewage reuse in industrial sectors, commercial buildings and public parks, in addition to present in-plant and street cleaning purposes, would increase total water reuse to about 10%. New water reuse technologies using membrane bioreactor (MBR) and microfiltration (MF) as tertiary treatment were implemented to assess their potential for their application in the Bangkok Metropolitan area. The MBR was applied to the treatment of raw sewage in a central treatment plant of the Bangkok Metropolitan area. The MF membrane was used for polishing the effluent of the treatment plant. The results show the quality of treated water from MBR and tertiary MF treatment could meet stringent water reuse quality standard in terms of biochemical oxygen demand, suspended solids and biological parameters. Constant permeate flux of the membrane was achieved over long-term operation, during which inorganic fouling was observed. This is due to the fact that incoming sewage contains a considerable amount of inorganic constituents contributed from storm water and street inlet in the combined sewerage systems. The total cost of the MBR for sewage treatment and production of reuse water is estimated to be about USD1.10/m3.

This paper evaluates potential sources of effluent reuse and feasible reuse applications in Istanbul Metropolitan Area, within the framework of all technical issues that must be considered in the planning and implementation of water reuse systems. Some potential sources of effluent for reuse have been eliminated based on location, on treatment plant size, or both. An assessment made of future possible reuse applications in the vicinity of wastewater treatment plants now under construction or planned has identified the following possibilities: Tuzla; industrial, urban and groundwater recharge; Küçükçekmece; urban, industrial, recreational, augmentation; Büyükçekmece; urban, industrial, augmentation; Ömerli - Elmalý; augmentation. The applications proposed for Istanbul have been based on technical, financial, economic, environmental and health considerations. The evaluation based on the current and anticipated programme of construction and commissioning of treatment facilities confirms that large scale reuse applications in Istanbul will not be a major consideration for the planning horizon.

Texto completoResumen
The most common problems in the fish processing industry relate to high water consumption and the generation of effluents with concentrated organic loads. Given that reuse can represent an alternative for sustainable development, this study sought to assess the potential for recycling effluents produced in a fish-processing plant. In order to do so, the final industrial effluent was analyzed using the American Public Health Association (APHA) standard effluent-analysis method (2005). In addition, the study assessed treatments which produce effluents meeting the requirements prescribed by different countries' regulations for reuse and recycling. The results found that effluents with smaller organic loads, such as those from health barriers and monoblock washing, can be treated in order to remove nutrients and solids so that they can be subsequently reused. For effluents produced by the washing and gutting cylinders, it is recommended that large fragments of solid waste be removed beforehand. Effluents can in this way attain a quality compatible with industrial reuse. This study further highlights the possibility of treating effluents so as comply with drinking water standards. This would potentially allow them to be used within the actual fish-processing procedure; in such a case, a revision of standards and measures for controlling use should be considered to prevent microbiological damage to products and risks to handlers and final consumers.

A preliminary, two-part study explored the extent to which authors reuse portions of their own text from previously published papers. All 9 articles from a recent issue of a psychology journal were selected as target papers. Up to 3 of the most recent references cited in each of the target articles and written by the same authors were also obtained. All target articles and their corresponding references were stored digitally. Then, using specialized software, each reference was compared to its target article to assess the number of strings of text identical to both papers. Only one of the nine target articles reused significant amounts of text from one of its references. To explore further the possibility of additional text reuse, the references in each of the 9 sets of papers were compared against each other. The new comparison identified 5 pairs of papers with a substantial number of identical strings of text of 6 consecutive words in length or longer, but most of the reused text was confined to the Method section. The results suggest that some of these authors reuse their own text with some frequency, but this was largely confined to complex methodological descriptions of a research design and procedure.

Texto completoResumen
Abstract Water scarcity and inadequate infrastructure for sanitation are two challenges that are emblematic to Kenya and other developing nations in Sub-Saharan Africa. Under such circumstances, water reuse has the potential to address these challenges but only under a favourable policy environment. In this paper, policy documents were considered as the ethnographic object to understand how people talk about water reuse in Kenya through policies, plans, regulations and guidelines. Using a general inductive approach to content analysis, the findings suggest that Kenya's policy on water reuse has progressed, especially in the recognition of the potential of reused water for addressing water scarcity, pollution, cleaner industrial production, food production, and climate change adaptation and mitigation. While many of the water reuse issues have been discussed under water and irrigation, environment and industrialization, other key sectors such as food and agriculture, housing, urban development and health remain silent on water reuse. Therefore, there is a need to take water reuse conversations beyond the water, environment, and industrialisation sectors if we are to address the water supply and wastewater management issues. Likewise, the study reminds us of the importance of foregrounding public perception and harmonized institutional arrangements in the success of water reuse in the country.

Reclaimed wastewater must be considered as an important component of the water budget in Jordan where water resources are rather limited. It has been estimated that wastewater effluents will amount to about 50% of the water deficit that is anticipated by the year 2000. This constitutes about 23% of the total renewable groundwater resource capacity. Quality characteristics of wastewater effluents from different treatment plants and other sources are presented. Review of institutional and legal aspects of water reuse is recommended toward encouraging treated effluent reuse. Outlines for a new reuse strategy have been suggested to ensure that wastewater reuse projects are operationally sustainable and environmentally sound.

Southeast Asian countries and Vietnam in particular are facing water security challenges; water reclamation is increasingly being considered as a favorable solution. Despite the availability of suitable technologies, several constraints often prevent stakeholders and especially decision makers exploiting their potential. In this paper we present the results of applying a decision support tool (DST) to evaluate water reclamation, support pre-feasibility studies and build capacity for water reclamation in Vietnam. The DST and its data are open access, providing information related to local and international water and wastewater quality standards. In this research we identified high potential Vietnamese case studies and conducted a systematic PISTLE analysis considering six dimensions (Political, Institutional, Social, Technical, Legal and Economic) at a multiple local stakeholder workshop. Key barriers and drivers for water reclamation implementation were identified. Measures proposed during the workshop could serve as a starting point for the development of water reclamation projects in Vietnam.
Các nước Đông Nam Á và đặc biệt là Việt Nam nói riêng hiện đang phải đối mặt với những thách thức về đảm bảo an ninh nguồn nước; cải tạo nguồn nước hiện đang được xem là một giải pháp thuận lợi. Mặc dù các công nghệ phù hợp đã có sẵn, nhưng một số hạn chế đã ngăn cản các bên liên quan và đặc biệt là những nhà làm chính sách có thể khai thác các tiềm năng của những công nghệ này. Trong bài báo này, chúng tôi trình bày các kết quả của việc áp dụng một công cụ hỗ trợ quyết định (DST) để đánh giá việc cải tạo nguồn nước, hỗ trợ các nghiên cứu tiền khả thi và xây dựng các khả năng cải tạo nguồn nước ở Việt Nam. DST và dữ liệu của nó là nguồn truy cập mở, cung cấp thông tin liên quan đến những tiêu chuẩn về chất lượng nước và nước thải của địa phương và quốc tế. Trong nghiên cứu này, chúng tôi đã xác định các tình huống điển hình có tiềm năng cao của Việt Nam và tiến hành phân tích PISTLE có hệ thống xem xét sáu khía cạnh (Chính trị, Thể chế, Xã hội, Kỹ thuật, Pháp lý và Kinh tế) tại một hội thảo của các bên liên quan tại địa phương. Những rào cản chính và yếu tố vận hành của việc thực hiện cải tạo nguồn nước cũng đã được xác định. Các giải pháp được đề xuất trong hội thảo này có thể đóng vai trò là điểm khởi đầu để phát triển các dự án cải tạo nguồn nước ở Việt Nam.

The reuse of wastewater by the pulp and paper industry reduces environmental impacts by contributing to raw water conservation, thereby making a greater volume of fresh water available for nobler purposes, and reducing wastewater treatment. This study evaluated a proposed system of water reuse at a Kraft pulp and paper plant in Brazil, based on a survey of water quality required by its consumption points, supplied by its water treatment plant. Results after ultrafiltration included: turbidity of 0,3 NTU and pH 7,5, average values of BOD 66,4 mg/L, COD 9,6 mg/L and the colour of 280,5 ppm Pt were measured after ultrafiltration. The ultrafiltered wastewater was considered available for reuse, and its quality was compared with that of the water supplied by the water treatment plant, which provided for the classification of potential reuse points. Water colour was identified as the limiting factor for reuse; thus the reuse points were two Kraft paper machines, and the water flow to the liquid ring formations that generate the vacuums inside nineteen pumps for these two machines. The advantages of this proposal for water reuse include: ultrafiltered water quality sufficient for the vacuum pumps, the small distance between the point of reused water generation and the paper machines section, and the reused water has no contact with the final product. The calculated cost and return time for the water reuse system was US$ 607.020,00 in 15 years.

The key approach to manage and prevent potential hazards arising from specific contaminants in water networks is to consider water as the main product delivered. This new concept, addressed as water-reuse risk assessment program (WRAP), has been further developed from hazard analysis of critical control points (HACCP) to illustrate the potential hazards which are the roots of hindering intra-facility water reuse strategies. For industrial sectors applying water reclamation and reuse schemes, it is paramount that the reclaimed water quality stays within the desired quality. The objective of WRAP is to establish a new methodology and knowledge, which will contribute to the sustainable development of industrial water management, and demonstrate its capabilities in identifying and addressing any potential hazards in the selected schemes adoption by the industries. A ‘what-if’ scenario was simulated using a refinery as a case study to show strategies on how to benefit reclaimed or reuse water based on reliable, applied and scientific research within the process integration area. In conclusion, the WRAP model will facilitate operators, consultants and decision makers to reuse water on a fit-for-use basis whilst avoiding contaminant accumulation in the overall system and production of sub-quality products from inadequate processes after several reuses.

The treatment of coal ash produced at coal-fired power plants requires high costs and has environmental problems. Therefore, a high proportion of coal ash has been reused, and the effective reuse of coal ash has been investigated extensively. In this study, the physical-chemical characteristics of bottom ash and fly ash sampled from a domestic coal-fired power plant were investigated. In addition, the shear behavior of bottom and fly ashes-sand mixtures was evaluated to verify the reuse potential of bottom and fly ashes. Direct shear tests were performed to evaluate the friction angle of the coal ash-sand mixture, which was used as an input parameter in the numerical analysis for slope stability to establish a framework for assessing the reuse potential of coal ash.

AbstractWater reuse has the potential to substantially reduce the demand on groundwater and surface water. This study presents a method to evaluate the potential of water reuse schemes in a regional context and demonstrates how water reuse propagates through the water system and potentially reduces pressure on groundwater resources. The use of Sankey diagram visualisation provides a valuable tool to explore and evaluate regional application of water reuse, its potential to reduce groundwater and surface water demand, and the possible synergies and trade-offs between sectors. The approach is demonstrated for the Dutch anthropogenic water system in the current situation and for a future scenario with increased water demand and reduced water availability due to climate change. Four types of water reuse are evaluated by theoretically upscaling local or regional water reuse schemes based on local reuse examples currently in operation in the Netherlands or Flanders: municipal and industrial wastewater effluent reuse for irrigation, effluent reuse for industrial applications, and reuse for groundwater replenishment. In all cases, water reuse has the potential to significantly reduce groundwater extraction volume, and thus to alleviate the pressure on the groundwater system. The water-quantity based analysis is placed in the context of water quality demands, health and safety aspects, technological requirements, regulations, public perception, and its net impact on the environment. This integrative context is essential for a successful implementation of water reuse in practice.

Abstract In the context of circular construction, the (potential) reuse of construction materials and building products is set forward as a general concept to reduce the environmental impact of buildings. But does this really lead to reduced impacts? A standardised framework to calculate the environmental impact of buildings over their life cycle is available through the European standards EN15804+A2 and EN15978 for life cycle analysis (LCA) in construction. The concept of reuse does however intrinsically focus on multiple use or life cycles. A correct quantification of the environmental impacts of reuse in buildings, requires a better understanding of the different mechanisms and issues at play. By means of critical assessment of the LCA methodology, in combination with a simplified case study, this paper provides insights in how different reuse options for products are valorised (or not) when calculating the environmental impact. It is shown that the LCA standard EN15804+A2 allows to quantify the impact related to different concepts of reuse at the beginning or the end of the considered life cycle. In general reused products will lead to larger environmental gains as the production stage (A1-A3) can be avoided. The environmental benefit related to the reusability of a product is typically reflected in a smaller difference in the end-of-life (EOL) stage (C1-C4). Also the relevance of existing concepts, such as module D, is discussed for each of the considered reuse options. Results show that module D can provide insights in the future potential of reuse (at EOL) for virgin products, but that the numbers are difficult to interpret and even misleading for reuse products. The results and discussion show the limitations of the current LCA framework for these types of products and identify the need for the integration of additional concepts to correctly valorise the potential of reusable products using LCA.

During the past 15 years, a wide variety of technologies have been developed that can be used for the treatment of wastewater for reuse applications. To assess the need for alternative technologies, potential reuse applications are reviewed. Changes in wastewater management, including the growing importance of decentralized wastewater management, is examined. The role of decentralized wastewater management is considered with respect to wastewater treatment, reclamation, and reuse. Technologies are presented and discussed for a wide range of reuse applications, ranging from individual homes to large centralized systems. The performance of representative technologies is assessed. A brief review of the water resources of Greece is presented to provide some perspective on the potential for wastewater reclamation and reuse in Greece.

Purpose Adaptive reuse of building assets is an important approach to sustainability. Adapting a building for new uses often involves complex factors in the decision-making process, particularly in conservation areas. The paper aims to show an evaluation process of the adaptive reuse potential of historic buildings that are subject to change in the Grand Canal area, a world heritage site in Hangzhou, China. Design/methodology/approach For this purpose, a model has been established with aggregated views of professionals on the degree to which a variety of factors affect the buildings’ potential for adaptive reuse. The model intends to help prioritise some of the buildings in the area for adaptive reuse, which is important for effective allocation of public resources. Interviews with professionals, analytic hierarchy process and the Delphi method have been used to establish the evaluation model. It is then applied to the Grand Canal area to generate indices for buildings’ adaptive reuse potential and the ranking of priority. The indices are generated through public scoring of historic buildings against the variables and calculated through the model. Findings The paper concludes that the evaluation process is an effective way to engage the public in the decision-making process and to balance conflict interests of various stakeholders in the management of historic building assets in conservation areas. Originality/value The research has proposed an evaluation model to help set priority of buildings subject to adaptive reuse and to help distribute public fund effectively.

Temporal coherence has the potential to enable a huge reduction of shading costs in rendering. Existing techniques focus either only on spatial shading reuse or cannot adaptively choose temporal shading frequencies. We find that temporal shading reuse is possible for extended periods of time for a majority of samples, and we show under which circumstances users perceive temporal artifacts. Our analysis implies that we can approximate shading gradients to efficiently determine when and how long shading can be reused. Whereas visibility usually stays temporally coherent from frame to frame for more than 90%, we find that even in heavily animated game scenes with advanced shading, typically more than 50% of shading is also temporally coherent. To exploit this potential, we introduce a temporally adaptive shading framework and apply it to two real-time methods. Its application saves more than 57% of the shader invocations, reducing overall rendering times up to in virtual reality applications without a noticeable loss in visual quality. Overall, our work shows that there is significantly more potential for shading reuse than currently exploited.

Texto completoResumen
The Kingdom of Saudi Arabia is experiencing an acute shortage of freshwater and is now looking for new water sources. In 2009, domestic water demand was 2,330 million cubic meters (MCM); about 730 MCM domestic wastewater was treated and 325 MCM of the treated wastewater (TWW) was reused. The remaining wastewater is typically discharged into the Arabian Gulf, Red Sea, sand dunes and wadis. These discharges can affect the environment and groundwater quality. This study investigated TWW reuse potential and developed a fuzzy multistage hierarchy framework for evaluating TWW reuse in Saudi Arabia. This research demonstrates that comprehensive reuse of TWW can replace approximately 1,631 MCM/yr of groundwater extraction. Reuse of TWW may produce approximately 654,500 tons of wheat (175 million US$), which is 20.5% of the national wheat demands in 2011, while the environmental pollution can be minimized. In this framework, four factors: cost, risk, benefits and social acceptance of TWW reuse were considered as the main criteria. These criteria can be evaluated using basic criteria and priority matrices following the hierarchy structure. The framework incorporates uncertainty in evaluating TWW reuse. A hypothetical case study is presented to apply the framework.

The ‘big data’ revolution has enabled novel types of analyses in the life sciences, facilitated by public sharing and reuse of datasets. Here, we review the prodigious potential of reusing publicly available datasets and the associated challenges, limitations and risks. Possible solutions to issues and research integrity considerations are also discussed. Due to the prominence, abundance and wide distribution of sequencing data, we focus on the reuse of publicly available sequence datasets. We define ‘successful reuse’ as the use of previously published data to enable novel scientific findings. By using selected examples of successful reuse from different disciplines, we illustrate the enormous potential of the practice, while acknowledging the respective limitations and risks. A checklist to determine the reuse value and potential of a particular dataset is also provided. The open discussion of data reuse and the establishment of this practice as a norm has the potential to benefit all stakeholders in the life sciences.

Abstract This paper presents a life cycle assessment (LCA) methodology for evaluating the environmental impacts of reuse in building projects and apply it to a case study in Switzerland with 11% of reused components in its total mass. The results show that the life cycle GHG emissions on the construction domain that includes modules A1 to A4, B4, and C1-C4, are 487 kg CO2-eq./m2. In the other hand, the indirect effect of reuse lead to avoided GHG emissions of 76 kg CO2-eq./m2. At the level of a product’s supply chain, the analysis demonstrates a significant reduction in the embodied impacts of the reused components compared to newly manufactured ones. The potential benefits from avoided manufacturing and waste management depend on the type of material that is reused.

Wastewater reuse is increasingly becoming an important component of water resources management in many countries. Planning of a sustainable wastewater reuse project involves multi-criteria that incorporate technical, economic, environmental and social attributes. These attributes of sustainability is the framework upon which the decision support tool presented in this paper is developed. The developed tool employs a user friendly environment that guides the decision makers in assessing the feasibility of implementing wastewater reuse. The input data into the tool are easily obtainable while the output is comprehensive enough for a feasibility assessment of treated wastewater reuse. The output is expressed in terms of effluent quality, costs, quantitative treatment scores and perception evaluation. Testing of the developed multi-criteria decision support tool using Parow wastewater treatment works in Cape Town showed the tool to be versatile and capable of providing a good assessment of both qualitative and quantitative criteria in the selection of treatment trains to meet various non-potable reuses. The perception module provided a quick assessment of potential user’s concerns on reuse and service providers’ capacity.

A large number of caravanserais were built during the Safavid era in Iran. However, due to the natural effects and human neglecting actions they are going to be ruined. Adaptive reuse of Safavid Caravanserais can be considered as one of the possibilities to preserve them from being demolished. The present study intends to categorize caravanserais based on the diversity of Iranian geographical and climatic zones as well as their distances from urban centers to determine their potential for adapting reuses. Since several of caravanserais still possess a characteristic building plan to accommodate travelers and are capable of retaining their functional elements, adaptive reuse can be applied. Therefore, the decision to reuse some of the buildings as hotels or restaurants seems rational.

Abstract Common water reuse applications include agricultural and landscape irrigation with treated municipal wastewater, industrial recirculation of process waters, rainwater collection, and groundwater recharge for non-potable and indirect potable reuse. As compared to other countries worldwide, water reuse is currently practised infrequently in Canada, with the focus of most of the water reuse effort within Canada on agricultural irrigation applications. Landscape irrigation and other non-potable urban uses are practised to some extent, but provide an opportunity for expanded application of reclaimed water. Similarly, while water recycling is practised to various degrees within specific industrial sectors, further industrial water reuse and recycling affords an opportunity to conserve large volumes of water. The Canada Mortgage and Housing Corporation (CMHC) has supported a great deal of research into treatment and reuse of domestic greywater for non-potable uses within individual buildings, as well as some work on rainwater collection and use. Groundwater recharge and potable reuse are practised to some extent in extremely dry regions of the world, but public health concerns with respect to emerging trace contaminants may limit the spread of these reuse applications. The main issues associated with each of the above applications are reviewed, and the state of Canadian water reuse and recycling is described.

In photovoltaic industry during wafer sawing significant amount of solar grade silicon is getting lost into sawing slurry. In the present paper, potential approach and routes for recycling and reuse of silicon wafer sawing slurry are explored. Various techniques were used including distillation, heavy liquid separation, acid leaching and high temperature processing. After distillation, the polyethylene glycol (PEG) can be separated and reused as lubricant. By dissolving silicon at high temperatures from the kerf into a clean molten pool of silicon metal or scrap, or into an alloying metal like Cu, SiC can also be separated and recovered. Depending on the impurity level, solar grade silicon can be finally produced from this waste stream in combination with necessary refining treatment for the applications in the PV industry. Furthermore, converting the kerf into SiC or Si3N4 particles as technical ceramic products is also explored. It is expected that the present research can pave a way to develop a total recycling route for an optimum use of this resource, and to minimize the environmental risk of the waste disposal.

Treated wastewater represents a significant potential source of reclaimed water for some beneficial reuses. However, public concern over the risks/health-related hazards of wastewater reuse has limited the general acceptability of reuse systems in many countries. It is important to manage the operation of recycled water systems in such a way that it will not adversely affect public health and the environment. Management of recycled water involves process control and compliance monitoring. This paper presents proposed unit process monitoring guidelines to classify the performances of treatment units according to the pollutant removal efficiencies and frequency of sampling to test for effluent quality suitable for reuse. The paper also highlights the procedure for proper inspection of treatment facilities to ensure optimum performances. It proposes minimum quality requirements for different reuse activities in South Africa such as domestic (toilet flushing, watering private gardens), irrigation (crops, landscape, public parks and golf courses, cemeteries), industrial (system cooling and process water) and other activities (construction works, street cleaning, fire protection, groundwater recharge). By employing the wastewater treatment monitoring and sampling procedures proposed in this paper, health-related hazards can be minimized while public confidence in reuse schemes will be enhanced.

Wastewater treatment and reuse has passed through different development stages with time. This study reviews the most essential changes in water reclamation and reuses over millennia, focusing on initial approaches in the Hellenic world and discussing the current situation. Based on archeological evidence and time records, the awareness of the Greeks regarding land disposal, irrigation, and water reuse is highlighted. The latter has evolved into a plethora of applications, with Direct Potable Reuse (DPR) representing one of the last modern frontiers. Currently, advances in wastewater treatment and the spreading of wastewater treatment plants producing large amounts of treated effluents increase the potential for water reuse. This is regarded as a critical option for the continuing protection of water resources and human health, while concurrently satisfying water demand, particularly in areas subject to increased water scarcity. The main constraints in the expansion of water reuse practices are discussed, focusing on wastewater treatment efficiency and quality effluent standards issues, as well as on the lack of motivations related to the acceptability of this practice by final users. Against these challenges, the need for a transition from an “issue-by-issue” approach to a broader integrated water management framework is highlighted.

Food production industry is the main producer of wastewaters with high fat, oil, and grease (FOG) content. FOG waste can be recovered from the wastewater stream by using physicochemical methods and reused considering their high methane potential. Popular method of FOG reuse is anaerobic co-digestion (AcoD) with wastewater treatment sludge and scum from the primary wastewater sedimentation tanks. This short review focuses on understanding the efficiency of FOG reuse possibilities by AcoD and takes a closer look at problems connected to degradation issues, gives an understanding on microbial changes during FOG degradation, and reviews enzymes involved in the degradation process.

The rapidly increasing business world demands that every company has the ability to compete. The policy in order to keep the company's smoking stable is to control production costs. PT. XYZ is an international manufacturing company that produces chocolate powder with several production processes in it. The decline in sales that occurred in PT. XYZ resulted in decreased company costs. In this problem, it is necessary to make improvements for PT. XYZ in order to obtain a solution to stabilize the company's production costs. The method used in this study is Quality Control Circle (QCC) with the application of the PDCA system. The results showed that the purchase of 2 ply paper bag packaging (PB2PL) is one of the activities that affect production costs with the largest expenditure in PT. XYZ. The improvement made is by applying PB2PL reuse. PB2PL is packaging used to package semi-finished materials, so that PB2PL can be reused which will provide benefits in terms of cost. The target of purchasing PB2PL after repairs is from 9,818 pcs to 3,500 pcs per month. Analysis of potential cost efficiency obtained by the first reuse of RP.47,859,052 per month, the second reuse of IDR 38,708,676 per month and the third reuse of IDR 29,558,300 per month. Analysis of potential costs with the application of the target is Rp. 30,798,617 per month. Application of PB2PL reuse in PT. XYZ for two months provided a cost efficiency of Rp.96,891,759. So that the problem would not occur again in the future, standardization was made in the form of a Standard Operating Procedure (SOP) reuse PB2PL.

CDL is a language for describing reusable software components. It facilitates the reuse of software components by providing a high-level model for component interfaces and mechanisms for describing the relationships between them. CDL extends the parameterisation mechanisms of modern high-level languages and helps to avoid the difficulties that can be encountered in specifying and instantiating generic components. CDL does this without explicit parameterisation or inheritance operators, and thus frees the designer from having to predict the reusability potential of the component. In these respects, CDL supports reuse at two levels. Components may inherit, generically instantiate or import other components. Furthermore, a CDL schema provides a design description that can itself be reused.

Whereas knowledge recombination research tends to focus on original knowledge component attributes and their recombinant value implications, we contribute to an emerging literature stream on knowledge reuse trajectories, investigating the temporal dimension of reuse by introducing the concept of recombinant lag, that is, the time that components have remained unused. Relying on organizational learning theory, we emphasize that it is important to consider not only the frequency of reuse but also the recency of reuse. Our core argument is that recent reuse of knowledge components can trigger a rejuvenation effect that influences the value of resulting inventions. Analyzing 21,117 fuel cell patent families, we find an unexpected U-shaped relationship between recombinant lag and the value of inventions, which is moderated by frequency of reuse. Conducting post hoc exploratory data analyses, we advance the concept of dormant components (i.e., valuable components that have remained unused prolongedly) as a potential explanation for this unexpected U-shaped pattern. Moreover, collecting and analyzing data on a second sample in the wind energy industry, we provide first indications for the generalizability of these unexpected findings. We contribute to a richer understanding of reuse trajectories, highlighting that next to the magnitude of reuse information flows, that is, information flows that are generated when components are reused, the timing of creation of these information flows shapes the value of subsequent recombination activities. We also contribute to extant research on the temporal dimension of knowledge recombination, pointing to recombinant lag as an important aspect next to component age.

This editorial considers hindrances that keep me from making sure that my used wooden furniture items don’t get thrown out at a point where their wooden content still has decades or hundreds of years of potential service left in them. I am a careless and lazy person, and I am not always appreciating the different ways in which other people might be ready to appreciate and utilize my cast-off items. Continued usage of a wooden item can be the ultimate in minimizing environmental impacts. I might envision that the only usage of an old, scuffed wooden dining room set is full restoration. But my niece might need it for her college apartment. A friend of a friend might need it for an informal basement art studio. Alternatively, if the set is really well beyond use in its original form, it could be converted into wood particles for particleboard or incinerated to generate renewable energy. Whether I use eBay, word of mouth, my church’s electronic bulletin board, or just put the item out by the curb on a sunny day, a wooden item of furniture has the potential to continue to provide valuable service for much longer than I might first imagine.

Built heritage as a manifestation of cultural heritage can be conserved if it continues to function through adaption or adaptive reuse. In reality, this process encompasses complex decision-making and remains a challenge amongst stakeholders. This study aims to evaluate the contemporary challenges in the convoluted process of adaptive reuse of the Town Hall, a significant heritage building of the colonial times in Shimla. It aims to identify the varying challenges in the adaptive reuse of the Town Hall, Shimla through the Adaptive Reuse Assessment Model (ARAM). Qualitative content analysis through structured and semi-structured questionnaires along with case study method has been adopted. The study suggests that the adaptive reuse of Town Hall is significantly impacted by locational, legal, and social challenges, while political and technical challenges effect moderately. The study also brings out that environmental, physical, and economic challenges have insignificant impact on the adaptive reuse of the Town Hall.

Accurately and rationally quantifying the environmental impact of construction and demolition waste (CDW) management is paramount, especially the environmental impact of different waste disposals, and more effective policies should be implemented to manage CDW. However, previous research on CDW disposal has typically ignored the potential for energy recovery and focused on a single environmental impact category. Therefore, this study aims to develop a conceptual framework to assess the environmental impacts under different CDW management scenarios (including reuse, recycling, energy recovery, and landfill), quantifying the global warming potential and resource consumption impacts under different scenarios. This framework incorporates Building Information Modeling to accurately collect data for feedback to the Life Cycle Assessment. The results indicate that Scenario 3, which considers the circular economy strategy, efficiently reuses metals, plastics, glass, and wood, generates recycled aggregate from concrete and cement, recycles bricks and tiles, and uses the remaining waste for energy recovery. This CDW management scenario, which prioritizes reuse and recycling, is the most effective in mitigating carbon emissions, resulting in a reduction of 6.641 × 105 kg CO2 eq. Moreover, it significantly conserves resources and prevents the energy consumption of 4.601 × 107 MJ. Among them, metal reuse saves 42.35% of resources, and plastic reuse saves 31.19% of resources. In addition, increasing the reuse rate and recovery rate can directly avoid carbon emissions and cumulative exergy consumption, effectively alleviating environmental issues. This study can provide new ideas for the treatment of CDW, which can provide a basis for the relevant government departments to formulate CDW management policies.

In Mediterranean countries, water shortage is becoming a problem of high concern affecting the local economy, mostly based on agriculture. The problem is not only the scarcity of water in terms of average per capita, but the high cost to make water available at the right place, at the right time with the required quality. In these cases, an integrated approach for water resources management including wastewater is required. The management should also include treated wastewater (TWW) reclamation and reuse, especially for agricultural irrigation. In Italy, TWW reuse is regulated by a quite restrictive approach (Ministry Decree, M.D. 185/03), especially for some chemical compounds and microbiological parameters. The aim of the paper is the evaluation of TWW reuse potential in Sicily. A Geographic Information System (GIS) was built at regional level to quantify and locate the available TWW volumes. In particular, the characteristics of wastewater treatment plants (WWTPs) were integrated, through the GIS, with data on irrigation district areas. Moreover, in order to evaluate the Italian approach for reuse practice in agriculture, the water quality of different TWW effluents was analysed on the basis of both the Italian standards and the WHO guidelines.
