Abstract:
Over the past decade, e-waste generation has been accelerated in the world as never before, particularly South-Asia is confronted with an enormous risk of e-waste intensification owing to both locally generated and internationally imported. There has been a gradual increase of e-waste generated in South-Asia and in 2019, 4,057 Kilo tons (kt) of e-waste was generated, which is about 16% of the Asian region. Though there is an urgent requirement to rectify the catastrophic accumulation of e-waste and for its effective eco-friendly management, inadequate legal implementation and poor enforcement, lack of awareness, weak formal e-waste collection and recycling process allow for escalating problems associated with e-waste, particularly towards the environmental and public health concern. Under these circumstances, this paper has been written by reviewing the available research findings, since 2000 to find out the current scenario of South-Asia. Unfortunately, the problem is also not seen as a hot topic to address by the researchers, there are only 106 research studies conducted in South-Asia. Out of that, a considerable number of studies were conducted only in India (54%), Bangladesh (23%), and Pakistan (16%). Sri Lanka, Nepal, and Bhutan shared the rest. As a matter of fact, many more studies are needed on environmental and human health effects, legal implementations, awareness and novel managerial strategies etc. to assist policymakers and other relevant authorities in making their decisions. Similarly, rather than facing threats alone, fighting against as a region would be ideal, which also helps to restrict intra movement of e-waste among the South-Asian countries.

Abstract:
Solid waste is global problem relating to environment, society and economics. Waste management is challenging issue as the quantity has been increasing with increase of population, urbanization and economic status. Some dozens of printed and online published books, journals, dissertations, website of agencies etc. were reviewed and by making outline and following guideline this article was prepared. It is found that the waste production varies from 0.25Kg to 1.38 Kg per capita per day in developing countries. In south South American countries it was recorded 1.07 Kg/capita/day, in Asian countries 0.4 to 1.62Kg/capita/day and in African region it was found 0.49 Kg/capita/day of waste production. The waste contains mostly biodegradable (50% to 80%). The collection system was very poor and from rural area only 10% to 20% waste and in urban area 44% to 90% of total produced waste was carried to collecting and management system. The common waste management’s adopted in developing countries were open dumping, landfill site, composting, incineration and open burning etc. From 18% to 92% of waste were found to dumping. In east pacific region 46% and in American countries 68.5% of total waste was carried to landfill site. The use of incinerator is scarcely found. Only in few countries well managed composting plants could be observed. Some landfill sites and incinerating plant shave generated electricity, biogas, brickets etc. Some pointed research gaps in this field are waste management and biodiversity, medicinal and hazardous waste management, vermicomposting etc. It can be recommended that for the waste management public awareness, participation of locals, application of reduction, reuse and recycling concept, waste management inside house premise, modernization and scientific management of solid wastes. Further researches are needed in different aspects of waste and management for the complete solution.

Abstract:
To date, most of natural materials used in manufacturing such as paper, glass, and cotton, have been replaced by plastic. Global production currently exceeds 320 million tonnes (Mt) per year, over 40% of which is used as single-use packaging, resulting in plastic waste [1]. In Malaysia, plastic shopping or carrier bags are one of the main sources of plastic waste, therefore, Malaysia is tracking global trends in both the overall generation of plastic waste and the consumption of single-use plastics. Malaysia ranks second in Asia after Philippines for annual per capita plastic use and, it ranks eighth among nations worldwide that mismanage plastic waste [2]. At every stage of its lifecycle, plastic poses distinct risks to human health. However, many traders still prefer to use non-environmentally friendly plastic bags because they are cheaper than biodegradable ones [2]. Chemicals are added to plastics to give them characteristics such as plasticity, colour, malleability, durability, or the hardness that some products need. Some groups of these chemicals such as bisphenol A (BPA) and phthalates have been identified as hazardous for human health, as they have been suspected of disrupting our hormonal system. BPA has been associated with several health problems such as ovarian chromosomal damage, decreased sperm production, rapid puberty, rapid changes in immune system, type-2 diabetes, cardiovascular disorder, obesity etc. Some studies have also claimed that BPA increases the risk of breast cancer, prostate cancer, pains, metabolic disorders, etc. BPA in women can be associated with impaired health, including obesity, endometrial hyperplasia, recurrent miscarriages, sterility, and polycystic ovarian syndrome [4]. Moreover, substances such as POPs, benzyne, and VOCs are present, which are all proven to adversely affect human health [3]. Exposure to harmful chemicals during manufacturing, leaching in the stored food items while using plastic packages or chewing of plastic teethers and toys by children are linked with severe adverse health outcomes such as cancers, birth defects, impaired immunity, endocrine disruption, developmental and reproductive effects etc. [3]. Thus, the objective of this study is to determine the impact of plastic to human health. This paper involved with secondary data collected from journals, proceedings, books, and internet sources regarding the topic. To conclude, Malaysia recycled just 24% of key plastic resins in 2019 and currently is not on track to meet the JPSPN (National Solid Waste Management Department) recycling target of 40% by 2025. Hence, removing plastic from the environment is incredibly urgent, as it creates environmental and health problems for both humans and marine life. Thus, plastics recognized to be a global contaminant of concern by policymakers, scientists, media, and public attention on the issue steadily increasing. Hence, promotion of plastics substitutes and safe disposal of plastic waste requires urgent and definitive action to take care of this potential health hazard in future [3]. One of the immediate campaigns launched was a No Plastic Bag Day (NPBD) in 2011 in raising awareness and reducing the use of single-use plastics in Malaysia. Through this campaign, free plastic bags in grocery stores were banned nationwide with a levy of 0.20 MYR was also added per plastic bag consumed in grocery stores and supermarkets to change consumer behaviour. This was followed by a nationwide ban on the use of straws in 2020 [5]. Recognizing that plastic pollution is a serious emerging issue, Malaysia’s Roadmap towards Zero Single-Use Plastics 2018–2030 was gazetted back in 2018 with the vision to take a phased, evidence-based, and holistic approach by involving all stakeholders in jointly addressing single-use plastics pollution in Malaysia [5].

Abstract:
From the mid-1990s to 2017, China was a major importer of recyclable waste, including plastic waste, e-waste, wastepaper, and copper scrap. However, after experiencing pollution from the recycling process and improper disposal of imported waste, at the end of 2017, China prohibited the import of certain types of waste, including household plastic waste and waste fiber. Consequently, some types of recyclable waste were rerouted to Southeast Asia. However, after receiving contaminated recyclable waste imports, Southeast Asian countries also tightened import restrictions on recyclable waste. These restrictions hindered the international recycling initiatives of certain manufacturers, which were model cases of the voluntary application of extended producer responsibility. When producers initiate recycling programs, they must compete with other recyclers to secure waste supplies and compete with other producers of the same kind. To compete in the waste and product markets, they must minimize recycling cost. To do so, some producers established international recycling systems; however, trade restrictions in some countries are forcing them to stop these programs. This paper reviews the impact of recyclable waste trade restrictions on recycling activities and producer-organized international recycling systems and argues that there is a need for an appropriate trade policy to facilitate environmentally sound recycling.

Abstract:
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.

Abstract:
Biodegradable wastes are waste materials easily degraded or broken down naturally by factors such as biotic (bacteria, fungi, plants, animals, etc.) and abiotic (pH, temperature, oxygen, humidity, etc.). This process enables complex substances to be broken down into simpler organic compounds which subsequently fade into the soil. This is a natural process that could be prolonged or rapid and poses little risks to the environment. These waste materials could be termed green waste; including food waste, paper waste, and biodegradable plastics such are found in municipal solid waste. Other examples of biodegradable wastes include sewage, manure, sewage sludge, human waste, waste from various slaughterhouses, hospital waste, dead animals, and plants. Biodegradable waste could be said to be recyclable or reused; furthermore, bio-waste recycling may also directly contribute to climate protection. They are generally known as useful waste. Recycling is one of the current waste management strategies having great benefits for the environment.

Abstract:
The circular economy has emerged as a policy goal with respect to the trade relationships between developed and developing countries. The aim of the circular economy is to take responsibility for the costs involved in recycling by going away from the linear economic model, which is briefly stated as 'take-recycle-dispose' with unused materials in at one end and externalised the wastes at the other. Recycling numerous unused structures is a persisting problem for Australia that can be resolved following this circular economy approach. To that end, an underlying aim of this chapter is to propose a bilateral agreement between Bangladesh and Australia that aims at recycling offshore structures of Australian companies in Bangladesh's ship recycling industry (hereinafter referred to as recycling industry). This chapter also sheds light on the challenges for Bangladesh in recycling the offshore structures in a sustainable way but disputes that those offshore structures will only increase the waste burden for Bangladesh.

Full text
Abstract:
The use of carbon fiber reinforced polymers (CFRPs) has expanded in many industries due to superior properties compared to traditional materials. Nevertheless, their recycling is challenged by immature recycling market and poor legislative support. This study evaluates the application and disposal of CFRPs within the different industries in Kazakhstan. The study adopted a market-based analysis approach to understand the up-to-date levels of application of CFRPs across manufacturing, construction, aviation, and other relevant industries of Kazakhstan. The study also considered CFRP markets and associated recycling practices in neighboring countries such as China and Russia which have a significant impact on Kazakhstan in terms of import and export of materials and waste. The research findings indicate that the application of CFRPs varies among industries, construction being the most prominent, however, their recycling is not as organized as in other waste types such as plastic, metals, etc. Russia and China will be generating thousands of tonnes of CFRP waste originating from the wind turbine and aviation sectors in future, from which Kazakhstan may also see some benefits. The findings of the study are deemed to be useful for the government of Kazakhstan and waste recycling associated stakeholders for future considerations.

Abstract:
Municipal solid waste (MSW), generated at an unprecedented rate due to rapid urbanization and industrialization contains useful recyclable materials like metals, plastic, wood, etc. Recycling of useful materials from MSW in the developing countries is severely constrained by limited door-to-door collection and poor means of segregation. Recovery of recyclables is usually performed by waste pickers, which is highly risky and hazardous for their health. This paper reports the development of a robotic mobile manipulation system for automated sorting of useful recyclables from MSW. The developed robot is equipped with a thermal imaging camera, proximity sensor and a 5-DOF robotic arm. This paper presents an approach for sorting based on automated identification from thermographic images. The developed algorithm extracts keypoint features from the thermographic image and feeds into clustering model to map them into a bag-of-word vectors. Finally, Support Vector Machine (SVM) classifier is used for identifying the recyclable material. We used the developed algorithm to detect three categories of recyclables namely, aluminum can, plastic bottle and tetra pack from given thermographic images. We obtained classification rate of 94.3% in the tests. In future, we plan to extend the developed approach for classifying a wider range of recyclable objects as well as to incorporate motion planning algorithms to handle cluttered environments.

Abstract:
In the European Union, the potential for recycling technological and post-consumer polymeric waste is untapped. Their recycling and reuse are very low, compared to other types of waste such as glass, paper, etc., and the rates of storage, even of incineration, is very high in terms of percentage. Therefore, by reusing them, but also making use of new advanced technologies, we can contribute to improving the quality of products, and to environmental protection by recycling waste, protecting human health by eliminating toxins during their incineration, but also increasing turnover for global economic agents. Thus, this paper presents the obtaining and characterization of an antibacterial compound based on EPDM elastomer and wood waste (sawdust). The antibacterial compound is characterized from a physical-mechanical and structural point of view (FT-IR), all according to standards in force.

Abstract:
Siempelkamp Nukleartechnik GmbH has gained lots of experience from melting ferrous metals for recycling in the nuclear cycle as well as for release to general reuse. Due to the fact that the world market prices for non-ferrous metals like copper, aluminium or lead raised up in the past and will remain on a high level, recycling of low-level contaminated or activated metallic residues from nuclear decommissioning becomes more important. Based on the established technology for melting of ferrous metals in a medium frequency induction furnace, different melt treatment procedures for each kind of non-ferrous metals were developed and successfully commercially converted. Beside different procedures also different melting techniques such as crucibles, gas burners, ladles etc. are used. Approximately 340 Mg of aluminium, a large part of it with a uranium contamination, have been molten successfully and have met the release criteria of the German Radiation Protection Ordinance. The experience in copper and brass melting is based on a total mass of 200 Mg. Lead melting in a special ladle by using a gas heater results in a total of 420 Mg which could be released. The main goal of melting of non-ferrous metals is release for industrial reuse after treatment. Especially for lead, a cooperation with a German lead manufacturer also for recycling of non releasable lead is being planned.

Abstract:
Abstract Carbon dioxide capture, utilization, and storage (CCUS), which includes conversion to valuable products, is a complex modern issue with many perspectives. In recent years, the idea of using carbon dioxide (CO2) as a feedstock for synthetic applications in the chemical and fuel sectors via reduction reactions has piqued interest. If the hydrogen is created using a renewable energy source, catalytic CO2 hydrogenation is the most viable and appealing alternative among the existing CO2-recycling solutions. CO2 hydrogenation has many chemical paths depending on the catalyst, and multiple value-added hydrocarbons can be generated. This research looks into a catalyst development for converting high CO2 gas field into methane and alcohols. The study focused on catalytic conversion of CO2 to methane over Ru based catalyst while in the case of alcohols using Cu based catalyst. Both catalysts were synthesized via impregnation techniques where the aqueous precursors’ solution were impregnated on the oxide supports, stirred, filtered and washed. The samples were then dried, ground and calcined. The synthesized catalysts were characterized using various analytical techniques (e.g., TPR, FESEM, N2 adsorption-desorption, XRD) for their physicochemical properties. The catalytic performance in CO2 hydrogenation was performed using a fixed bed reactor at various factors such as temperature, pressure, feed gas ratio and space velocity. The experimental findings indicate that conversion of CO2 to methane over Ru based catalyst resulted in >84% CO2 conversion with 99% methane selectivity in the range of temperature 280 – 320 °C and at atmospheric pressure. In the case of hydrogenation of CO2 to alcohols, the catalytic performance of Cu based catalyst exhibited CO2 conversion of >11% and selectivity towards alcohols, C1 and C2, both at 4% with reaction temperature of 250 °C and pressure 30 bar. These findings revealed that methane could easily be formed from CO2 as compared to alcohol. However, both technology conversions are dependent on the catalyst selection and its’ activity. Process parameters need to be optimized to maximize targeted product formation and suppress the side products.

Abstract:
In the 1990–2010s in the region, measures were taken to increase the volume of waste processing of large industrial enterprises. However, the following problems remained unresolved: lack of funding, outdated recycling technologies, lack of attention from regional and federal authorities. There were also positive steps. In particular, the disposal of hazardous waste was started at enterprises where this has not happened for a long time (according to Usolekhimprom, Baikal Pulp and Paper Mill, Angarsk Metallurgical Plant, etc.). Huge volumes of ash and slag materials and waste from the timber processing industry were used.

Abstract:
Elastomeric and plastic materials are used in different sectors of the European Union, and their recycling and reuse is still at a low level, compared to other types of waste (paper, glass, etc.). By approaching an efficient global strategy related to waste management, it is possible to make the transition to a circular economy with low CO2 emissions, offering the population a cleaner and safer environment. Due to the transformation of waste by various methods into new value-added products, we can say that their life cycle contributes to the efficiency of the economy and to the reduction of the negative impact on the environment. Research can make a difference in preventing the generation of technological and post-consumer polymeric waste by making biodegradable polymer composites that are harmless to the environment and ecosystem. The biodegradable polymer composites based on EPDM elastomer and rubber waste (rubber powder) were made on equipment specific to elastomers and characterized rheologically and physically-mechanically according to the standards in force.

Abstract:
Despite growing interest and recognition of urban and peri-urban agriculture (UPA) as a nature- based solution, there is limited empirical evidence in countries like India on its role in reconfiguring goals on environmental functions (such as biodiversity, waste management, water recycling, micro-climate regulation, etc.) and social wellbeing (such as food and nutrition security, gender relations, work burdens, land tenure and community ties). A need to address this gap led to the ideation of the project ‘Urban and peri-urban agriculture as green infrastructures’ ( UPAGrI ). When UPAGrI started in 2019, the research on UPA in India was thin but growing. However, the practical experience of urban farming across Indian cities is thriving and diverse, built on decades of bottom-up experimentation. Within the landscape of our ever-changing cities, we found vibrant communities-of-practice sharing seeds and knowledge, engaged online influencers discussing composting and water reuse, and stories of farming becoming sites of multi-generational bonding and nutritional security. This compendium is a collection of 29 such innovative UPA practices from across the different cities in the country. These diverse case studies are loosely categorized into four themes: environment and sustainability; food, nutrition and livelihood; gender and subjective well-being; and urban policy and planning. Written mostly by practitioners themselves, the case studies collectively recognise and celebrate UPA innovations and practices, serving as a repository of lessons for peer-to-peer learning, and demonstrating how UPA can be one of the many solutions towards sustainable, liveable Indian cities.
