Abstract (sommario):
In EU waste management policy the waste avoidance and reuse are under the highest priority and the recycling takes the third place while recovery and disposal are the least favourable options. The EU member states have to implement strict waste management policies based on this approach however though all countries have to prepare and implement waste management plants, their have achieved different results in waste management. The article aims to analyse the selected waste management indicators covering all stages of various wastes management ranging from prevention to recycling etc. available at Eurostat database and to present empirical comparative case study on waste management for Baltic. The different Multi Criteria Decision Making models were applied for comparing and ranking Baltic States based on their achievements in waste management in 2020. The case study revealed that the best performing country in waste management among Baltic States was Lithuania having the best indicators of waste generation per GDP and recycling rates of municipal waste and plastic packaging waste. Estonia was lowest ranked country according waste management due to very high overall total generated waste per capita and packaging and plastic waste per capita etc.

Abstract (sommario):
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 (sommario):
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.

Abstract (sommario):
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.

Abstract (sommario):
- 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.

Abstract (sommario):
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

Abstract (sommario):
AbstractConcrete is one of the fundamental materials in the construction industry. Typically, concrete is composed of sand, cement, aggregate, and added water to the cement ratio. To enhance sustainability and reduce the negative effect on the environment from industrial waste, recycling waste material into the concrete mixture is becoming an area of research by substituting some of the concrete ingredients with some of the recycled waste material in order to reduce the amount of fine natural aggregate used in the construction industry, maximise the strength and minimise the overall weight of the concrete product. Waste foundry sand is a by-product of sand casting, a waste product of the metal casting industry. The improper disposal of this waste foundry sand (WFS) could cause environmental issues. Consequently, its possible use in building materials, product design, construction, and other fields is crucial for mitigating environmental limitations. To minimise negative environmental impacts, researchers have proposed reusing this waste foundry sand by replacing, fully or partially, some of the standard natural sand within the concrete mixture. This paper investigates the mechanical and physical properties of concrete cubes containing recycled sand-casting material by demonstrating the experimental work to determine the potential benefit or limitations of using this material within the concrete in the construction and product design industries. According to the experimental results, waste foundry sand, with a substitution ratio of up to 30%, had a compression strength of circa 23 N/mm2 and reached up to 78% of the strength of a standard control sample within 7 days. The results hence suggest that waste foundry sand can be used in the production of concrete products when such reduction in strength is not critical. Such a range of products could include curbs, garden slabs, cycling pavements, gravel boards, etc. Additionally, utilising waste foundry sand will help to reduce the use of natural sand and the need for landfill sites, which has several advantages, including cost savings and environmental protection by reducing CO2 emissions during transportation.

Abstract (sommario):
AbstractSignificant changes in the strategic goals of the construction sector at the global level have been visible in recent years. By implementing the fundamental principles of sustainable development and circular economy, the modern construction industry tries to contribute to a healthier environment by reducing CO2 emissions, minimizing waste landfills, and preserving non-renewable natural resources. The possibilities of reusing prefabricated concrete elements of existing buildings instead of their traditional recycling on a material level or disposing of them in landfills are analyzed in this paper. Special attention in the research was placed on the carbonation of prefabricated reinforced concrete elements of buildings, as it is one of the most frequent processes that accelerate the deterioration of RC structures. Long-term carbonation processes inevitably result in reinforcement corrosion and accompanying damage to the concrete cover, therefore some constrains for the further use of prefabricated RC building elements must be precisely defined. In this study, the potential use of prefab RC building elements was determined by calculating the depth of carbonation while taking into account the age of buildings and environmental conditions (relative air humidity, position of prefab element). Depending on the thickness of the carbonized concrete and the type and intensity of damage to the reinforcement and concrete, various variants for further use of the dismantled prefabricated RC building elements were proposed (reuse without restrictions, use in the interior of new buildings, use in less demanding facilities, reuse after application of a protective coating, replacement of the protective cover and reuse etc.).

Abstract (sommario):
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 (sommario):
Farmers apply fertilizers to their plants to encourage growth as well as their personal financial development. Nonetheless, chemical fertilizers, as we are all aware, contaminate the water and soil, harming the surrounding flora and fauna. Therefore, use of organic waste that has been discarded into the environment is necessary. Based on certain research, earthworm species can be employed for the recycling of organic waste. Regulating soil processes is a major function of earthworms. As the most significant soil ecosystem engineers, they are generally accepted. Earthworm species favor extremely organic food over the soil. We can use waste materials like cow dung, kitchen waste, agro-residues, institutional and industrial wastes, textile industry sludge and fibers, etc. that are released into the environment to make vermicompost because they contain a lot of organic content.

Abstract (sommario):
Biological waste management is an important aspect of environmental sustainability that requires proper disposal and treatment of biological waste produced from different sources. Biological waste is waste that comes from biological processes including wastes from plants, animals, hospitals, household, and municipal solid waste (MSW). Biological waste management involves the collection of waste from waste-producing sources, transport, processing, disposal, or recycling. The biological waste management technologies include composting, incineration, landfill, anaerobic digestion, and bioconversion to produce biofuels, i.e., bioethanol, biodiesel, biogas, etc. Urbanization, industrialization, changing lifestyles, and consumption patterns of the public have resulted in increased production of biological waste worldwide. Production of biological waste is affecting soil health and biodiversity, crop productivity in case of discharge of industrial liquid waste into the fields, and human health, and contributes to global warming and climate change. Furthermore, every year, approximately one-third of the food produced is lost from the food chain as waste, resulting in increasing hunger, economic loss, inflation, and inequality among people. Hence, biological waste needs proper treatment to conserve the environment, and the bioconversion of waste to produce renewable sources of energy like biogas, biodiesel, and bioethanol will result in the reduction of emission of greenhouse gases.

Abstract (sommario):
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 (sommario):
Green computing can be described as efficient resource management in distributed computing environments such as cloud, fog, and edge computing environments. In green computing, green refers to the eco-friendly environment with environmental responsibility to efficiently manage the computing resources. Mainly, two significant reasons are associated with global warming issues from the distributed computing perspective. They are high power consumption of cloud datacenters and high CO2 emission rate. According to many survey reports, every year, cloud datacenters alone produce nearly 90 million metric tons of CO2 into the environment, and now, this high power consumption of datacenters has become one of the primary reasons for global warming issues. Also, it stated that this CO2 emission rate would increase by 8% every year if it did not identify proper control measurements. Therefore, it is crucial to enhance e-waste management by increasing the efficiency of computing resource usage and minimizing high power consumption, high CO2 emission rate, inefficient recycling policies, etc.

Abstract (sommario):
Supercapacitors have great potential for applications in electric and hybrid vehicles, wind farms, and low-power equipment due to their large specific power density and long-term cyclic stability. Waste supercapacitors are required to be recycled for making their use sustainable from the waste electronic equipment perspective. This chapter describes a recycling approach for end-of-life supercapacitors based on shredding and mild thermal treatment. Further, the safety regulations for supercapacitors with respect to the operating conditions like temperature, potential window, self-discharge, leakage current, etc., are discussed. We further include discussion about the impact of supercapacitor applications on human health. We also include a brief analysis about the ethical issues as well as the social impacts of supercapacitor applications. This chapter summarizes the various aspects of the implementation of supercapacitors and their recycling prospects.

The immense utilization of plastics has produced an enormous amount of plastic waste. So, basically there is a necessity created for proper method for plastic waste management. As, we know plastics is the most essential part of our life and used in every application and has a very versatile portfolio used everywhere from industries to households. We can say that the use of plastics is inevitable. In the present time adoption of sustainability principles including selection of the best recycling process is important for optimum utilization of the resources. As there are various plastic waste management strategies available, their prioritization on the basis of several criteria like health, safety, the environment impact, etc. is relevant for the stakeholders involved in this sector . Main objective as to apply by using different criteria as multi- criteria decision making to conduct an analysis which are based on a hierarchical structure that is multi-level and analysis of plastic waste management methods. The AHP approach is a (MCDM) tool which we adopt in our study to depict the best suitable method for the Plastic Waste Management for the industries. As the identification of criteria for the plastic recycling process based on the literature review and expert discussions was done for this the study was initiated. Further, the weightage of different criteria and ranking of the available methods were done using AHP. Four commonly used plastic waste management alternatives were evaluated and findings reveal that recycling is the best alternative. This study will help the industries in selection of best possible techniques and methods for plastic waste management. By this deep study we will be able to find out the best method which can be used for plastic waste management and AHP approach gives us a clarity and it takes various attributes to reach out to a result. This technique is inter-related to Operation Research subject. From this paper we can conclude that out of Incineration, landfilling, Mechanical Recycling and Road filling , Mechanical Recycling comes out to be the best method that can be used for Plastic Waste Management and it should be mainly utilized further.

Abstract. The use of waste fibers from the mechanical machining of parts in the formulation of new concretes is of great importance for the protection of the environment because, on the one hand, it makes it possible to recover the materials already used and to on the other hand, it allows nature to be protected from excessive exploitation of the reserve of artificial metallic fibers. The new concretes have high performance (high compressive strength, low porosity and permeability, durability, etc.), however these concretes are fragile and have low tensile strength, which limits their use. The objective of this study is to see the influence of the introduction of waste fibers on the behavior of new concretes. It is necessary to study the physical-mechanical characteristics of these concretes composed of these wastes in the hardened state.

Abstract (sommario):
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 (sommario):
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 (sommario):
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 (sommario):
Despite continuous research and development on drilling fluids and waste minimization during the last 40 years, offshore drilling waste (OSDW) remains a significant environmental concern for the petroleum industry. OSDW contains three types of contaminants namely, heavy metals from drilling fluid, oil from oil based mud or petroleum contamination and naturally occurring radioactive substances from exposed formations. In this study a promising and permanent solution based on recycling of OSDW as road construction materials has been investigated. It has been revealed previously that five to ten percent of some waste materials such as recycled asphalt pavement, tire rubber, glass, roofing shingles, polythene etc. can be added to hot mix asphalt (HMA) concrete without sacrificing its strength and performance. These wastes can be added to the HMA by either replacing the mineral filler or proportionately reducing the amount of virgin material in the original mix. In this laboratory test study, different percentages of OSDW were added as aggregate replacement and the properties of resulting blends were evaluated. Three beneficial actions, namely, incineration, dilution and solidification took place. At the end, the effectiveness of using OSDW was determined with the Marshall stability and flow, permeability of HMA concrete, leachability and resilient modulus. It has been found that for the drilling waste used in this research the percentage that can be used in HMA concrete without sacrificing its properties is as high as 20%. Even though the percentage of waste that can be used as aggregate replacement varies with waste types and properties, the proposed technique offers significant promises for OSDW recycling.

Abstract (sommario):
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 (sommario):
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 (sommario):
Decommissioning of retired nuclear plants and facilities demands the proper management of the process, both for economic reasons and for retaining public confidence in the continued use of nuclear power for electricity generation. There are significant potential benefits, both economic and environmental, in recycling materials from retired nuclear facilities for new uses rather than disposing of them as radioactive waste. Although it is technically possible to decontaminate many retired nuclear components to reduce contamination levels to below those appropriate for free release into the public domain, there is some public unease at the prospect of formerly contaminated materials passing into unrestricted public use. Greater support for recycle can be achieved by converting decontaminated materials into products for new controlled uses, particularly within the nuclear industry. Irrespective of the future of nuclear power, the industry has a need for many new items such as waste containers, replacement components etc. Good economics can be achieved by decontaminating the materials and then using existing non-radioactive manufacturing facilities for fabrication of new components. Provided that materials have first been decontaminated to below unrestricted release levels, there is no objection in principle to using non-radioactive facilities for recycling and manufacturing activities, so long as the materials are properly tracked to prevent their uncontrolled release. Surface decontamination has an important role to play in these activities. Efficient and economic decontamination processes are needed to prepare materials for recycle. The EPRI DFDX Process is a process for achieving these objectives. Recent progress with this process is described.

Abstract. Slags obtained from the Vale Copper Cliff smelter in Sudbury, Ontario, Canada, were investigated as sustainable engineering materials in this study. The recycled smelter waste products can remove toxic contaminants from the aqueous environment as well as be used in the construction industry (as aggregates, cement admixtures, filling materials), soil improvement for agricultural purposes, and other value-added applications and products. The removal mechanisms of the heavy metals (such as Zn, Pb, and Cu, etc.) from aqueous solutions could be physical or chemical adsorption, ion exchange, oxidation-reduction, etc. At the same time, using recycled smelter slags in various engineering applications can help with waste reduction, disposal cost reduction, resource recovery, and increased reused activities. The present study helps explore the scope of using recycled materials in the treatment or construction industry. Using industrial smelter slag as a recycling or renewable resource rather than a waste product has environmental and economic benefits. The study also specifically discusses Ni smelter slag's composition, application, treatment efficiency, opportunity, economic benefits, and circularity for sustainable management.

Abstract (sommario):
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.

Abstract (sommario):
We believe the climate crisis will be resolved in cities. Today, while cities occupy only 2% of the Earth's surface, 57% of the world's population lives in cities, and by 2050, it will jump to 68% (UN, 2018). Currently, cities consume over 75% of natural resources, accumulate 50% of the global waste and emit up to 80% of greenhouse gases (Ellen MacArthur Foundation, 2017). Cities generate 70% of the global gross domestic product and are significant drivers of economic growth (UN-Habitat III, 2016). At the same time, cities sit on the frontline of natural disasters such as floods, storms and droughts (De Sherbinin et al., 2007; Major et al., 2011; Rockström et al., 2021). One of the sustainability pathways to reduce the environmental consequences of the current extract-make-dispose model (or the "linear economy") is a circular economy (CE) model. A CE is defined as "an economic system that is based on business models which replace the 'end-of-life' concept with reducing, alternatively reusing, recycling and recovering materials in production/distribution and consumption processes" (Kirchherr et al., 2017, p. 224). By redesigning production processes and thereby extending the lifespan of goods and materials, researchers suggest that CE approaches reduce waste and increase employment and resource security while sustaining business competitiveness (Korhonen et al., 2018; Niskanen et al., 2020; Stahel, 2012; Winans et al., 2017). Organizations such as the Ellen MacArthur Foundation and Circle Economy help steer businesses toward CE strategies. The CE is also a political priority in countries and municipalities globally. For instance, the CE Action Plan, launched by the European Commission in 2015 and reconfirmed in 2020, is a central pillar of the European Green Deal (European Commission, 2015, 2020). Additionally, more governments are implementing national CE strategies in China (Ellen MacArthur Foundation, 2018), Colombia (Government of the Republic of Colombia, 2019), Finland (Sitra, 2016), Sweden (Government Offices of Sweden, 2020) and the US (Metabolic, 2018, 2019), to name a few. Meanwhile, more cities worldwide are adopting CE models to achieve more resource-efficient urban management systems, thereby advancing their environmental ambitions (Petit-Boix & Leipold, 2018; Turcu & Gillie, 2020; Vanhuyse, Haddaway, et al., 2021). Cities with CE ambitions include, Amsterdam, Barcelona, Paris, Toronto, Peterborough (England) and Umeå (Sweden) (OECD, 2020a). In Europe, over 60 cities signed the European Circular Cities Declaration (2020) to harmonize the transition towards a CE in the region. In this policy brief, we provide insights into common challenges local governments face in implementing their CE plans and suggest recommendations for overcoming these. It aims to answer the question: How can the CE agenda be governed in cities? It is based on the results of the Urban Circularity Assessment Framework (UCAF) project, building on findings from 25 interviews, focus group discussions and workshops held with different stakeholder groups in Umeå, as well as research on Stockholm's urban circularity potential, including findings from 11 expert interviews (Rezaie, 2021). Our findings were complemented by the Circular Economy Lab project (Rezaie et al., 2022) and experiences from working with municipal governments in Sweden, Belgium, France and the UK, on CE and environmental and social sustainability.
