Full textAbstract:
The article presents an alternative method of recycling of dispersed metal waste, based on a continuous solid-liquid-phase process, implemented in rotary tilting furnaces (RTF). The new proposed method of recycling allows processing wastes with almost any composition and state from metal to oxide and multicomponent wastes (shavings, fine scrap, mill scale, aspiration dust, sludge, etc.). The wastes can be even contaminated with moisture, oil, and organic impurities. The method developed does not require preliminary preparation of the initial materials (cleaning, homogenization, pelletizing, etc.). The finished products are ingots (pigs) for subsequent processing aiming the particular chemical composition or cast alloys of certain brend.

Full textAbstract:
Despite the increase in popularity of the zero waste (ZW) concept, the successful implementation of this concept in waste management is still facing many challenges. The plastic recycling rate in Australia is at only about 9.4% (in 2017–2018). The state of Victoria (in Australia) has proposed an ambitious 10-year plan to upgrade its waste and recycling system and to divert about 80% of waste from landfills by 2030. The aim of this research is to study this currently proposed waste management plan and to develop a simulation model to assess the feasibility of achieving 80% diversion rate by 2030. The feasibility of achieving zero plastic waste by 2035 has also been assessed. In this direction, the existing knowledge of global ZW implementation has been reviewed to gain understanding of the challenges, obstacles, and uncertainties in achieving the ZW target. A simulation model is established using a method called double baselines. This method was developed to address the limitation of data availability for the model development. The model was run in 4 scenarios including one for Victoria’s current 10-year plan. Outcomes from the model are produced using six key considerations, including the rate of plastic consumption, waste to landfill, diversion rate, recycling rate, relative accumulative effort, and cost. The findings of this study point out that Victoria’s current plan for achieving an 80% diversion rate by 2030 is possible. On the other hand, the study results also suggest that achieving zero plastic waste by 2035 is less likely to happen. Hence, opportunities for improvement especially towards achieving the zero plastic waste are also presented.

Energy harvesting also known as power harvesting or energy scavenging is the process by which energy is derived from external sources solar power, thermal energy, wind energy, salinity gradients, and kinetic energy, captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor. Energy harvesters provide very small low-energy electronics. While the input fuel to some large-scale generation costs money (oil, coal, etc.), the energy source for energy harvesters is present as ambient background and is free. For example, temperature gradients exist from the operation of a combustion engine and in urban areas, there is a large amount of electromagnetic energy in the environment because of radio and television broadcasting

Full textAbstract:
Worldwide, over 1.3 billion tonnes of food goes to waste each year, and much of this is disposed of in landfill, which is costly to the economy and the environment. This study targeted food waste management in local food service businesses as the third largest producer of food waste and a sector that has received less academic attention than other food waste producers (such as household food waste). Questionnaires and interviews were used to investigate current food waste management practices within food service businesses in a Local Government Area in Adelaide, South Australia. Twenty-two respondents completed the online questionnaire and three of these businesses also participated in an interview—two in-person at their business premises and one via an online teleconferencing system. It was found that 54% (n = 12) of these businesses have practices in place to recycle their food waste, while 46% (n = 10) do not. Insufficient kitchen space and the difficulty of separating food waste from non-compostable rubbish were reasons given for not recycling food waste, and the single most important factor that would encourage food waste recycling cited by businesses was the provision of a free, green organics bin. Motivations for recycling food waste included compassion for the environment and the desire to divert waste from landfill. These insights may help local government implement solutions to reduce food waste from entering landfill.

Abstract Urbanization, development of economy, increasing population and improved living standards and lifestyle have caused a sharp growth in waste. Inappropriate or inefficient waste disposal techniques can cause serious air, soil, and groundwater pollution, which subsequently can negatively affect the urban environment and threaten the health of residents. The goal of waste management is to move to a circular economy in which waste does not exist. If there is no possible way to reduce or reuse waste, the best solution is recycling it. Recycling brings abundant benefits on the economic and ecological levels levels, and helps reduce overall human health risk of adverse impacts. Recycling of the waste-cables which contain PVC and copper replaces the production of virgin PVC and mining of copper from copper ore, it reduces landfill solid waste pressures, saves energy and water sources, reduces emissions to environment, and also reduces negative impacts from improperly dispose of waste, etc. This paper presents an overview of recycling techniques for the waste-cables containing copper as a core and polyvinyl chloride as an insulating layer or sheath. It also lists advantages and disadvantages of these techniques and importance of recycling this type of waste.

Full textAbstract:
In 2018–2019, 85% of discarded plastics were landfilled in Australia. In Western Australia (WA), only 5.6% of plastics were recovered for reprocessing. With several Asian Countries imposing import restrictions, which were the prime destination for recyclables from Australia, the whole scenario for the waste industry has changed. Australia has now adopted export bans for recyclables, including plastics. WA is at a fork in the road; WA needs to rethink its relationship with plastic materials. This study explores how to create local markets for recycled plastics underpinning circular principles. The study examines barriers and drivers to enable markets for recycled plastics in WA through questionnaires, surveys, and interviews with relevant stakeholders. Poor source separation, low and inconsistent plastic waste feedstock, and virgin plastic competition are some of the challenges, while new investments in recycling infrastructure, WA’s take-back scheme for beverage containers and circularity frameworks are drivers. This study concludes that a modulated fee-based product stewardship model focused on product design, along with strategies such as green procurement and landfill management modifications would promote a circular plastic waste economy in WA. This can create markets for secondary recycled plastics, minimize the over-reliance on fossil fuels and prevent plastics from leaking into ecosystems.

Waste generation is increasing with the increasing of population at Mymensingh city but the waste management practice of the Mymensingh city corporation is not well established. The present study was conducted to find out profitable opportunities for municipal solid waste (MSW) management of Mymensingh city. Both primary and secondary sources were used to collect data as fulfillment of the study. Twenty two different locations of 5 wards in the city were visited for collecting these data. In the city estimated amount of waste produce 150 tons/day where 40-50% biodegradable and 15-25% recyclable paper, plastic, glass, metal etc. Currently waste is not being collecting and disposing scientifically due to unavailability of facilities, thus creating environmental pollution as well as unable to earn profit. Resource recovery and recycling could be a good option to reduce waste and earn profit from recyclable materials such as plastic, paper, metal etc. Besides this composting could be useful to produce bio fertilizer and bio gas from biodegradable wastes. By selling bio-fertilizer and biogas city could also earn profit. Integrated waste management combination with reduce, recovery, recycling and composting would be better solution for managing waste in the city. J. of Sci. and Tech. Res. 3(1): 41-48, 2021

In the era of industrialization and modernization, pollution caused by industrial wastes has become one of the biggest challenges most countries are facing. Wastes such as plastics, ceramics, paper, metals, composite, etc. are the predominant detriments to the environment. Although composite materials account for just a small proportion in the waste stream, they are difficult to process and possess a great number of potential risks to the environment. At the same time, recycling and recovering composite waste materials are more challenging than other easy-to-handle waste materials. This paper will first present an overview of the methods used to recycle composite wastes, then it will further orientate recycling technologies suitable for Vietnam.

- Production of steel in steel Industry is accomplice for the generation of solid waste materials like sludge, slag, dust etc. In recent days most part of wastes are generated from steelmaking process which is a focus point now-a-days. The solid waste generation, presently in Indian steel industry is in the range of 400 - 500 kg/t of crude steel and recycling rate varies between 40 - 70 % which lead to higher production costs, lower productivity and further environmental degradation. It is very essential not only for recycling of the waste valuable metals and mineral resources but also to protect the environment. I Solid waste management in steel industry is broadly classified in “4 R” i.e. reduce, reuse, recycle and restore the materials. The aim of the paper is to explore the various developments for total recycling of solid waste generated from steel industry, so that the vision for making “clean & green steel with zero waste” can be achieved for survival and growth of steel business in future. Keywords—Steel, Reuse, recycle, solid waste, sustainable development.

The main directions of mining and industrial wastes’ utilization are the production of building materials, their use in the construction industry without additional processing, and also the production of metals from metal-containing raw materials. It should be noted that current waste is preferable for the production of building materials, since they preserve the primary physical and mechanical properties and chemical composition and, moreover, can reach the consumer bypassing all other steps that are mandatory for waste consolidated (transportation, storage, etc.). For the production of building materials, not less than 30% of overburden and refinement tailings are suitable, almost all metallurgical and fuel slags, waste products of fertilizers and building materials. Even larger amounts of waste can be used for various laying and burial works (construction of road bases and dams, filling of worked out areas, leveling of the relief).

To achieve sustainable development, logistics enterprises need not only to reduce costs, but also to save energy for environmental protection and improve customer service level. The improvement of reverse logistics management level of waste tires is of great significance to improve the efficiency of the automobile industry. In this paper, multi-objective programming is adopted to establish the waste tire recycling network model. The decision variable is whether the network nodes are set or not, the traffic flow between nodes. Constraints include meeting customer demand, balance of flow in and out of logistics nodes, etc. The model is solved by ε- constraint. Taking the actual data of the enterprise as an example, the operation results show that the operation cost, carbon emission and customer transportation distance can get an consistence within a certain range. Waste tire logistics enterprises can realize the simultaneous improvement of profit, environmental protection and customer service level.

Around 5000 tons of food waste are prooduced every day in Iraq, accounts for about (50%) of the waste that we get rid of .Waste sent to landfill for disposal may breakdown and produce methane gas that causes greenhouse effect ,as well as odour , epidemics , and disease because of the disintegration. The aims of the research are to produce organic fertilizer through the recycling of domestic refuse. It has been working through this research to collect the domestic food waste which represent the nitrogen source, as well as the remains of cleaning and trimming of various trees and the remains of lawn mowers, and use of sawdust white wood which represent the carbon source. Working on dried and arranged in layers of perforated plastic containers for the purpose of ventilation, it was moisturized with two different types of water and monitored fertilizer maturity for four months. Previously the fresh water was used for the purpose for moisturizing the mixture (tap water) later the domestic wastewater have been used. The comparison was made between the results of tests performed; the test has come up with the resalt that the use of "domestic wastewater" rich in living organisms and bacteria to hydrate the mixture is better than the use of "tap water". The felicitous fertilizer is rich with nutrient nitrogen 2.3%, phosphorus 13% and potassium 20% etc. There are a number of important factors affecting the process of production of fertilizer, including air ventilation, temperature, and moisture content in the mixture, which ranges from 40-60% to provide a suitable medium for microorganisms within the mixture. Where less than 40% lead to dry mixture and kill organisms.

The recycling of waste plastics is considered as one of the strategies to tackle the issue of environmental pollution caused by commodity plastics all over the world. Recently, many universities have incorporated topics related to recycling and plastics waste management into their curricula at different levels to increase awareness as well as to develop new recycling technologies. In this study, one of the most important waste recycling problems is given as the project for the undergraduate students of chemical engineering to analyze the effectiveness of the project-based learning (PBL) approach in the school curriculum. A team of students was assigned with the task of recycling post-consumer polyethylene terephthalate (PET) bottles through an experimental and design approach. From the experimental data, students designed a recycling plant with a proposed capacity to produce 1 ton of recycled granules per day through the project-based learning approach. Evaluation of the project was carried out at various stages and it was found that the students acquired the required skills and applied them effectively. The outcomes of the present study clearly establish that the problems which have societal impacts, such as waste management, environmental pollution, etc., can be effectively communicated to the student community through the PBL approach, which can lead to increased motivation and enhanced critical thinking abilities.

Full textAbstract:
The article analyzes the problem of construction and demolition waste disposal in Ukraine, which is especially relevant due to the increasing number of housing renovation projects and the intensification of national construction projects. Construction waste accounts for almost a third of the waste generated in most developed countries. The most efficient disposal method is recycling, i.e. recycling of secondary building resources (SBR). However, the share of recycled construction waste in Ukraine lags far behind developed countries (it is about 6% of its total volume). The high level of waste generation and low rates of its use as secondary raw materials (SRM) have led to the fact that a significant amount of solid waste accumulates annually in the industrial and civil sectors of Ukraine, only a small part of which is used as SRM, the rest ends up in landfills. The difference between waste management in Ukraine, compared with other developed countries, is in the large volumes of waste generation and the lack of infrastructure to recycle it. The issues of the environmental impact of construction waste are considered, and the main cost-effective technologies for processing SBR are identified and considered in this research. With the help of market mechanisms and government regulations, these technologies may become promising for investment and their development will be beneficial for small and medium-sized businesses. Perspective areas of construction waste recycling in order to obtain demanded products are presented; existing advantages and technologies of processing SRM are also considered: solid waste processing, biothermal composting, wood waste processing, recycling of construction waste and metallurgical slag, etc.

Full textAbstract:
There is a growing interest in electronic wastes (e-wastes) recycling for metal recovery because the fast depletion of worldwide reserves for primary resources is gradually becoming a matter of concern. E-wastes contain metals with a concentration higher than that present in the primary ores, which renders them as an apt resource for metal recovery. Owing to such aspects, research is progressing well to address several issues related to e-waste recycling for metal recovery through both chemical and biological routes. Base metals, for example, Cu, Ni, Zn, Al, etc., can be easily leached out through the typical chemical (with higher kinetics) and microbial (with eco-friendly benefits) routes under ambient temperature conditions in contrast to other metals. This feature makes them the most suitable candidates to be targeted primarily for metal leaching from these waste streams. Hence, the current piece of review aims at providing updated information pertinent to e-waste recycling through chemical and microbial treatment methods. Individual process routes are compared and reviewed with focus on non-ferrous metal leaching (with particular emphasis on base metals dissolution) from some selected e-waste streams. Future outlooks are discussed on the suitability of these two important extractive metallurgical routes for e-waste recycling at a scale-up level along with concluding remarks.

Additional to these determinants, in the present study, the influence of social media was analyzed along with the actions taken by the government and nongovernmental organizations, with the purpose to include and to capture, as much as possible, a high amount of determinants in the e-waste recycling process. Nevertheless, the demographic or socio-economic variables, such as age, gender, income, education, number of family members, etc., have shown over time to have a contribution to predicting the consumers’ pro-recycling behavior. As on one side, in the research literature, the opinions related to which of the demographic or socio-economic factors can have an impact on the recycling behavior have been divided and, on another side, a series of researchers believe that the discrepancies in the findings of different studies can be due to culture in various countries, in this paper we conducted such an analysis with reference to the Romania’s case. The results have shown that the demographic variables, such as age and gender, can have a contribution to predicting residents’ pro-e-waste recycling behavior. Based on these findings, the policymakers can gain a better understanding of the e-waste recycling phenomenon and on its main triggers, with results in creating better policies for sustaining a proper e-waste managing system.

Over the past years the target for waste recovery/ recycling has significantly increased in Romania, in according with the EU Directives. Nowadays, the competitive contexts of the current market lead the manufacturers to obtain novel and custom-made products using new technologies and quality raw materials. Such resources can be consisting of low-cost waste/by-products and in the processes of converting them into value-added products. On the other hand, the necessity for recycling waste is important under the strict European legislation. Regarding glass, the key sources of waste are container/ packaging glass, flat glass, electric and electronic equipments, domestic glass, E-glass, etc. According with source, waste glass can be: pre-and post-consumer waste glass. Now many recycling processes have been studied, developed and applied in industry. The major challenge is represented by creating of innovative and sustainable technologies and making it suitable. But recycling of glass is technologically more complicated than other waste (for example: paper). In case of glass, the most sustainable route is to use it for re-melting processes and obtaining a new glass. Glass is 100% recyclable but not all waste/cullet can be used for the manufacturing of any type of glass, due different chemical composition and the prohibitive shipping costs from collection points to glass factory. In this study, authors paid attention to the recycling process of soda-lime glass (post-industrial flat glass) and proposed the thermal embossing technique of glass, using glass slumping process, in order to obtain decorative products with aesthetic impact and functional role. An input image is prepared by applying different enhancement techniques, adjusting contrast, transferring into grayscale image in 256 shades of gray. The result image is transferred in Computer Aided Manufacture (CAM) software to refine the surface geometries and to obtain with rapid tooling the mould for glass. The method used for tooling fabrication consists of machining a block of suitable material with a Computer Numerical Controlled (CNC) machine which is known as a subtractive method. The next stage consists in applying of the heat treatment, using an electrical furnace. The major advantages of the embossing method for converting waste glass in value-added products is represented in the fact of use reduced energy comparing with the classic route of re-melting, possibility of obtaining bespoke products, ready to use in architectural and decorative fields. In addition, environmental benefits that results from processing waste glass are the reducing the raw materials (virgin) and the CO2 emissions.

Abstract: Garbage collection is an important task of ensuring that our communities have a pleasant environment in which to live. But the main problem we face today can be reduced by reducing or minimizing the amount of waste transportation, specific waste. A compactor can be used to reduce the amount of waste streams. The waste burden remains the same so there are no savings from the total waste generated. However, the amount of waste can be reduced by up to 80%, eliminating the need to empty the dumpster many times, resulting in lower pick-up charges. These paper focus on, to identify and analyze concepts and strategies for waste recycling. Its aim is to reduce their negative impact on the environment and human health and natural resources. Right now, garbage is an existential problem in India, so you must find financial solutions. In developing countries, reducing the amount of waste is one of the major challenges that need to be addressed to improve living conditions. By using management in waste recycling, one can contribute to urban development, but we must remember that there is a significant cost involved in waste management. In conclusion, we noted that the necessary discussions are taking place nationally and internationally to adopt management strategies in the area of waste recycling. Keywords: Solar energy, Waste Management, Organic Composting, Composting process, Modern Composting etc.

The Department of Natural Resources in Queensland, Australia are presently carrying out a comprehensive Strategy called the Queensland Water Recycling Strategy (QWRS) to determine future Government directions in the whole area of water recycling. This strategy is considering the beneficial use of all waste streams such as domestic sewage, industrial and agricultural wastes, as well as urban stormwater. Following a workshop held during the initial phase of the strategy it was determined that a high priority must be given to the demonstration of recycling practices not being utilised in the State, or presently being practiced in an unsustainable manner. Three separate types of recycling projects are being carried out, the first being based on demonstrating recycling on a large new urban development close to Brisbane, the second associated with demonstrating the complex treatment processes associated with the higher levels of recycling, and the third associated with demonstrating community based recycling schemes.

"E-waste" is a popular, informal name for electronic products nearing the end of their "useful life. “Electronic waste" may be defined as discarded computers, office electronic equipment, entertainment device electronics, mobile phones, television sets, and refrigerators. "E-wastes are considered dangerous; ascertain components of some electronic products contain materials that are hazardous, depending on their condition and density. This includes used electronics which are destined for reuse, resale, salvage, recycling, or disposal. Others are re-usable (working and repairable electronics) and secondary scrap (copper, steel, plastic, etc.) to be "commodities", and reserve the term "waste" for residue or material which is dumped by the buyer rather than recycled, including residue from reuse and recycling operations. Many of these products can be reused, refurbished, or recycled in an environmentally sound manner so that they are less harmful to the ecosystem. This paper highlights the hazards of e-wastes, the need for its appropriate management and options that can be implemented.

Full textAbstract:
Solid waste disposal is a major challenge in many industrialized and developing nations, both in metropolitan regions as well as rural ones. The collection and disposal of municipal solid waste (MSW) is a serious issue facing metropolitan areas in many nations today. An effective MSW management strategy must satisfy all of these criteria: financial viability; technical feasibility; social and legal acceptability; and ecological friendliness. Small and large cities alike have a major difficulty in dealing with solid waste management.
One of the current study topics is the valuation of food organic waste. Existing waste disposal methods include the typical landfill, incineration, composting, and other methods of handling solid waste. Composting and anaerobic digestion have traditionally been the most widely employed methods for the treatment and exploitation of the organic part of MSW (AD). The amount of organic solid waste (OSW) being generated globally is rising at an astronomical rate. Agricultural waste, domestic food waste, human and animal wastes, etc. comprise the majority of OSW. They're often used as animal feed, disposed of in landfills, or burnt. OAWs are made up of protein-, mineral-, and sugar-rich components that may be employed as substrates or raw materials in other processes.

In addition to increasing requirements to adopt more circular economy approaches, Australian municipal waste management systems also face challenges due to the loss of capacity to export waste overseas. Accordingly, these systems will require effective sorting and collecting of waste. Selective Waste Collection (SWC) is the collecting and sorting of household recyclable waste. The study aimed at investigating how SWC systems in an Australian municipality (Wollongong) are organised and their role in the proper management of household plastic waste. For this purpose, we mapped the household plastic waste management system and characterised every SWC system in terms of, e.g., weight and type of plastic collected. We estimated that only about 20% of the household plastic waste generated in 2018–2019 was collected via the SWC systems. Our investigation enabled us to estimate Wollongong’s household plastic waste generation, recycling rate, and final disposal; identify the gaps in knowledge and challenges faced by the systems; and offer recommendations to overcome them. The challenges include contamination, insufficient community awareness, and lack of consistent waste data. Our recommendations include a transition from a commingled to a non-commingled system. The results provide a useful approach and crucial information for performance evaluation, strategy, and planning purposes.

Full textAbstract:
The research is aimed at comparing different methods of municipal solid waste treatment (waste burial, composting, complex recycling) depending on the values of generated greenhouse gases. In order to compare waste burial and composting of municipal solid waste based on amount of generated greenhouse gases the calculation methods used for compiling the National Inventory, were taken. The mass balance method was used to estimate the output of a product of complex recycling. The municipal solid waste components differ by amount of degradable organic carbon and decomposition rate but have the largest mass. The municipal solid waste treatment techniques consist in placing such waste at landfills and dumps which are sources of environmental pollution, for example, by greenhouse gases. There are other organic waste treatment methods, such as composting via different technologies, burning, recycling etc. But all of them are also associated with greenhouse gases emission. Easily decomposed organic waste can be used for production of organic fertilizers, but a mandatory requirement, that is separation from the general municipal solid waste stream at the time of waste production, should be complied with. A complex recycling of easily decomposed organic waste, including anaerobic and aerobic composting is offered as an efficient way of waste management. The article presents a comparative analysis of various methods of municipal solid waste treatment based on the amount of greenhouse gases emitted in the Odessa Region. It considers three waste treatment approaches: all waste mass is to be placed at landfills and dumps, composting of some of park and garden waste and burial of other components, complex recycling of food, park and garden waste and some of paper waste according to the developed scheme. Complex recycling offers the least value of total greenhouse gases emission over a five-year period whereas waste disposal is characterized by the highest value thereof. The complex recovery of components containing bioavailable organic carbon through anaerobic fermentation method excludes emission of greenhouse gases into the atmosphere, as the biogas produced can be collected and extracted. However, over a long period, even after two-stage complex recycling, the total emission of greenhouse gases will be lower comparing to other methods of easily decomposed organic waste treatment. Emission of greenhouse gases in case of waste disposal has a prolonged nature whereas emission of greenhouse gases in case of composting occurs within a short period of time which should be taken into account when analyzing the prospects of solving the municipal solid waste problem.

Full textAbstract:
Steel slag is a major waste product of the steelmaking process. Owing to its chemical composition, it can be reused as a raw material in steel mills and a substitute for aggregates in engineering. In 2016, the Republic of Korea (ROK) introduced the Environmental Assessment of Recycling (EAoR) system for the safe recycling of waste products, which divides recycling methods into either matrix contact or non-matrix contact types; numerous challenges have been raised regarding weaknesses in the matrix contact type. Consequently, the standards for matrix contact recycling of slag (inorganic waste) have become stricter, and the recycling applications have also become more diverse. This study investigates the treatment, recycling, and management of steel slag in the ROK. In 2019, the annual generation of slag in the ROK exceeded 23.03 million tons with a recycling rate of 98.3%, showing a high level of recycling, compared with that of the United States (81.3%), the European Union (87%), Australia (100%), and Japan (98.4%). However, a comparative analysis of overseas slag recycling systems and recycling standards found that the recycling applications and recycling standards of slag in the ROK were somewhat stricter than those in the European Union and the United States. Furthermore, an investigation comparing the applications of recycled slag in different countries showed that the ROK could expand its applications of recycled slag. The limitation of the EAoR system was that the excluding products, environmentally certified from Korean Standards in the EAoR regulations, might be attributing to environmental pollution. The leaching and toxicity tests for recycling application of steelmaking slag were evaluated and showed no significant negative effects. Lastly, there is an urgent need for environmental standards relating to slag that can be recycled as a product, and the recycling and environmental label certification for products should also be amended. In addition, the applications of steelmaking slag were necessary to partially extend according to the hazardous characteristics.

Informal electronic waste (e-waste) recycling in Africa has become a major public health concern. This review examined studies that report on the association between e-waste exposure and adverse human health outcomes in Africa. The review was conducted following the updated version of the Preferred Items for Systematic Review and Meta-analysis (PRISMA 2020) statement checklist. We included papers that were original peer-reviewed epidemiological studies and conference papers, written in English, and reported on e-waste exposure among human populations and any health-related outcome in the context of Africa. Our results from the evaluation of 17 studies found an association between informal e-waste recycling methods and musculoskeletal disease (MSD) symptoms and physical injuries such as back pains, lacerations, eye problems, skin burns, and noise-induced hearing loss (NIHL). In addition, the generation and release of particulate matter (PM) of various sizes, and toxic and essential metals such as cadmium (Cd), lead (Pb), zinc (Zn), etc., during the recycling process are associated with adverse systemic intermediate health outcomes including cardiopulmonary function and DNA damage. This systematic review concludes that the methods used by e-waste recyclers in Africa expose them to increased risk of adverse health outcomes. However, there is a need for more rigorous research that moves past single pollutant analysis.

Recycling municipal solid waste has become a challenging task for municipalities. Appropriate recycling efficiency evaluations are, thus, essential to find practical benchmark learning targets for inefficient municipal solid waste authorities (MSWAs). This study developed a recycling performance evaluation procedure by subgrouping MSWAs with prominent local demographic features, such as population density, ratio of senior citizens, tourism index etc. Principal recycling relevant factors for MSWAs in each group were then collected, and data envelopment analysis (DEA) was applied for efficiency evaluation and benchmark learning targets. A case study of 181 MSWAs in Taiwan demonstrated the suitability of the proposed procedures. An assessment of the required efforts for efficiency improvements revealed that, in an unsegregated scenario, inefficient MSWAs representing a rural subgroup required maximum efforts to fulfill the efficiency targets, which was on average 61% higher than that determined in their respective subgroup. Furthermore, the unsegregated scenario revealed proximal efficiency results for the urban subgroup. The results indicated that consideration of local demographic features was essential for a fair assessment of recycling efficiency. Additionally, evaluating MSWAs with similar local demographic features was superior in obtaining appropriate benchmark learning targets for the inefficient MSWAs and, consequently, exhibited practicality for improving walkthroughs to achieve the efficiency goal.

Many people feel that solid waste management is simply putting waste into a vehicle and unloading it at a dump. But if we consider it true then why do so many towns suffer from uncollected refuse, blocking street and drains, harbouring flies and rats and degrading urban environments? Successful solid waste management is rarely achieved without thought, efforts and much learning from mistakes. Preparation and management of a good solid waste management system needs inputs from a range of disciplines, and careful consideration of local conditions. Keeping in mind all above, the present paper is an attempt to combine several aspects of environmental, biological, chemical and civil engineering to resolve the problem related to solid waste management for the Moradabad district. It is felt that there is need to focus more on recycling and resource recovery as a common practice, need to focus on environmental impacts (e.g. surface and groundwater) of solid waste around dump sites etc a plan was prepared for its proper management. At present A2Z Waste Management Private Limited is involving for the solid waste management work in Moradabad. Data related to waste generation, composition of municipal solid waste etc is provided by Nagar Nigam, Moradabad, Municipal Corporation and A2Z Moradabad. In Moradabad, there are about 100 notified slum settlements constituting about 21% of the total population i.e. 1,80,000. The steady incremental in the city population results in the increase of domestic waste generation. This project consists of the hierarchy of solid waste management starting from sources, types and composition of solid waste, waste generation, handling, storage, collection, reduction, combustion, upto landfill and recycling for waste management.

Abstract The use of recycled products largely depends on the existence of viable end markets. In Australia, state regulations have a pivotal role in creating and stimulating the market for recycled construction and demolition (C&D) waste products. Hence, this study aims to identify regulatory barriers and enablers affecting C&D waste end markets. This study employed a qualitative research approach to understand the effectiveness of the current C&D waste regulations. The data collection concerned a series of interviews with C&D waste experts across five Australian states (i.e., Victoria, New South Wales, Western Australia, Queensland and South Australia). Overall, 27 interviewees were recruited from various stakeholder groups (e.g., recycling, government, construction, consultation & manufacturing). The findings provide an insight into the primary factors affecting market development for recycled C&D waste materials. A series of reforms are proposed to improve the current regulatory framework. They aim to address issues around recycled C&D waste uptake in construction projects. The research contributes to the body of knowledge in the field of built environment and design by providing first-hand information about regulatory mechanisms involved in utilising recycled products. Policymakers and authorities can use the results to devise advanced regulations that provide a level playing field for all parties involved in C&D waste management in Australia and other countries with similar contextual conditions.

The waste market is a large segment of international trade, which allows earning on the recyclable treatment materials and the waste trade. The separate waste collection allows obtaining a better quality of recyclable materials, which can be processed without additional sorting. Toda, measures for infrastructure development for separate collection, recycling, and incineration of solid municipal waste are established as part of the Strategy of solid municipal waste management in theRussian Federation. At the same time, disposal is the primary method of waste management. As a result, there is a problem of development of separate waste collection system which is aimed at reducing the use of a non-eco-friendly and desirable method of waste management – disposal. OECD proposes many standards for separate waste collection are possible, including integration of waste management hierarchy, development of extended producer responsibility practices, stimulation and training of population in a separate waste collection, etc. These measures allowed OECD countries, for example,Germany,Sweden,Austriato become world leaders in the field of waste treatment. These countries improve the quality of the environment, earn through recycling, resale of garbage, saving the money by re-using of useful components contained in the wastes.

The current searching was done by the keywords in main indexing systems including PubMed/MEDLINE, Scopus, and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. The most important points challenging areas that represent opportunities for stakeholders to look into in China are, put in place suitable economic incentives to encourage restaurants to get more involved in the formal system, create a comprehensive regulation system to benefit all relevant stakeholders by clearly defining their respective roles and responsibilities, which is necessary for the proper functioning of the whole system. In China, the most important regulations, policies and plans are regulations on safety issues of food waste treatment, detailed countermeasures on organizing, educating, supervising, and inspecting the work on food waste reduction in China, and detailed plant for household waste collection and treatment, issued by Chinese government, state council, and ministry of environmental protection. Setting national goals, awareness-raising campaigns, strict and appropriate regulation, stakeholder engagement, biorefinery and food waste recycling to animal feed are important strategies for better waste management. The most important food waste management practices in China are source separation, animal feed, rendering, composting, co-digestion, anaerobic digestion, incineration, landfill, and etc. Understanding social factors influencing household behavior is utmost importance; public education and specific communication highly contribute to improve recycling.

According to Eurostat in 2018, Romania occupies the penultimate place in waste recycling. Packaging waste, generated in the European Union, was 174 kg per capita, but these quantities varied between Croatia - 67.8 kg per capita and Germany - 227.5 kg per capita. In the first place are waste paper and cardboard - 41%, plastic - 19%, glass - 18%, wood - 16% and metal - 6%, in the European Union 2018, these types being the most common household waste. Of the types of packaging waste, glass with 18.7%, is the greatest danger to the environment, being a waste that is not biodegradable, obtained by melting a mixture of quartz sand, limestone and soda ash. Glass packaging waste is 100% recyclable, theoretically, if the recycling and sorting process is followed, removing impurities (paper, sand, metals, etc.), non-compliance with the process will make the smelting process impractical. By recycling one ton of glass, we save 660 kg of sand, water for four people a day and avoid emitting 315 kg of carbon emissions from the greenhouse. Glass packaging waste is recycled with various professional equipment, which is used to obtain glass granules of different sizes, from 0.1 mm to 10 mm, the edges of the granules are rounded and have the appearance of fine sand. The present study presents the use of sand obtained from recycled and crushed household glass, in constructions, filters for domestic water, thermal insulation. The sand obtained from the recycling of household glass has a great advantage, it can be used cold and hot, temperatures weighing 1000C °, substantially reducing production costs, higher resistance by up to 30% and processing time.
