Call for participatory waste governance: waste management with informal recyclers in Vancouver

ABSTRACT It is no news that waste generation is on the increase, making it more problematic for governments to manage. In the global south, the informal recycling sector has become notable for its contributions to municipal waste management through resource recovery, as shown by the current body of research. However, due to the seemingly well-organised waste management system, the existence and roles of this sector in municipal solid waste management in the global north are largely under-documented. Using a community-based research methodology and applying mixed methods, we examined the roles of the informal recycling sector in municipal waste management in Vancouver, British Columbia as well as their level of participation in decision-making. Results demonstrate that the sector enhances waste diversion and recovery efforts and works in collaboration with the city government as well as other stakeholders. The study also shows that informal recyclers (locally called binners) participate in some level of decision-making processes such as the Single-Use Item Reduction Strategy; however, their participation in other key waste management decisions including the City’s Recycling Bylaw remains challenging, which significantly impacts their day-to-day survival. We, therefore, highlight the need for a transformative participatory policy/decision-making process to promote more harmonious and inclusive municipal waste management.

Assessing the functional relationship between the formal and informal waste systems: A case-study in Catalonia (Spain).

The present study draws from data collected with informal recyclers in the autonomous region of Catalonia in northeastern Spain. The purpose of the investigation is to determine the relationship between the formal and informal recycling sectors in Catalonia and determine how each of their activities impacts the other. From the case study in the city of Granollers, it was determined that from the spring of 2018 to the fall of 2019, the informal recyclers had the potential to collect roughly 44% of the cardboard in their geographical area, helping to meet the environmental goals of the region, but receiving no recognition for their work nor acknowledgement regarding their role in the waste management system. This investigation also analyzed the economic relationship between the formal and informal systems, and the effects that international events, such as China's National Sword policy, had on that relationship. It was determined that the embeddedness of waste systems and global waste markets affect not only the formal system, but their relationship with the informal system as well.

Evaluation of models for household recycling behaviour in high-rise buildings: A Chinese case study in urban Guangzhou.

Recycling strategies and waste management for the source separation of recyclables are still in their infancy in China and many other developing countries. Unlike formal recycling systems with strictly regulated management in high-income countries, waste management and recycling activities in low-income and middle-income countries are predominantly informal. Formal recycling systems often have very small amounts of recyclables in comparison to informal recycling systems. Considering the Chinese case of urban Guangzhou, where formal and informal recycling systems coexist, this study investigated household recycling behaviour and explored the sociodemographic and contextual factors that affect this behaviour. Based on data collected through questionnaire surveys and interviews, a model of the use of public recycling facilities (UPRF) and a model of the use of informal recycling sectors (UIRS) were evaluated using correlations and multiple regression analyses. The findings indicated that the use of public recycling facilities can be significantly predicted by the launch of a source separation scheme, the physical setting and satisfaction with public recycling facilities. The sociodemographic variables did not significantly predict the use of public recycling facilities but did significantly predict the use of informal recycling sectors. This study's findings have implications for researchers and policymakers and shed light on public designs for sustainability.

Formal or informal recycling sectors? Household solid waste recycling behavior based on multi-agent simulation

Urban household solid waste recycling and management are complex adaptive systems with multiple agents, stages, and elements. Previous studies neglected the impact of municipal residents' behavioral decisions on recycling sectors. In this study, the degree of regret-joy and personality characteristics were introduced into a multi-agent-based model to simulate the action decision-making of agents under different strategies. The results demonstrate that, without the government's role, nearly 60% of municipal residents preferred the informal recycling sector (IFRS). Meanwhile, the formal recycling sectors (FRS) find it difficult to attract urban residents because of their low income levels. Regarding a single policy, the subsidy policy is more beneficial than the regulation policy for increasing the income of the FRS from 20 to 250 Yuan. However, neither of the two single policies can weaken the market competitiveness of the IFRS. Moreover, a comprehensive policy combining both subsidies and regulations has enabled more than 60% of urban residents to choose the FRS, thereby increasing its profit and market share to 270 yuan and 500 kg, respectively. These results provide policy suggestions for optimizing the waste recycling management systems.

Using weighted entropy to measure the recyclability of municipal solid waste in China: Exploring the geographical disparity for circular economy

Solid waste recycling in developing countries has been largely relying on the informal recycling sector which intelligently uses the tacit knowledge within the hierarchical network of labor division to capture the value from the geographically uneven distribution of waste generation and demands on secondary materials. Previous studies on solid waste recycling mainly have a material-centric view on economic value. In this paper, an entropy-weighted recyclability index (EWRI) is developed to quantify the recyclability of Municipal Solid Waste (MSW) in China at the prefectural city level by integrating the road transportation density and regional recycling capability into the categories of waste physical components regarding the cost to deliver the waste from generating sources to the conversion sites for recycling. The result confirms the existence of an east-west gradient regional disparity in recyclability of Municipal Solid Waste (MSW) among cities for the recyclable components. The 339 prefectural cities were classified into 4 grades, namely “best, good, normal, and difficult” for the recyclability of local MSW with guidelines for planning of regional recycling infrastructure, respectively. In conclusion, general guidelines for the building of wise-waste city infrastructure to fit the local context in developing countries is advised.

Passive Air Sampling of PCDD/Fs, PCBs, PAEs, DEHA, and PAHs from Informal Electronic Waste Recycling and Allied Sectors in Indian Megacities.

Xenobiotic chemical emissions from the informal electronic waste recycling (EW) sector are emerging problem for developing countries, with scale and impacts that are yet to be evaluated. We report an intensive polyurethane foam disk passive air sampling study in four megacities in India to investigate atmospheric organic pollutants along five transects viz., EW, information technology (IT), industrial, residential, and dumpsites. Intraurban emission sources were estimated and attributed by trajectory modeling and positive matrix factorization (PMF). ∑17PCDD/Fs, ∑25PCBs, ∑7plasticizers, and ∑15PAHs concentrations ranged from 3.1 to 26 pg/m3 (14 ± 7; Avg ± SD), 0.5-52 ng/m3 (9 ± 12); 7.5-520 ng/m3, (63 ± 107) and 6-33 ng/m3 (17 ± 6), respectively. EW contributed 45% of total PCB concentrations in this study and was evidenced as a major factor by PMF. The dominance of dioxin-like PCBs (dl-PCBs), particularly PCB-126, reflects combustion as the possible primary emission source. PCDD/Fs, PCBs and plasticizers were consistently highest at EW transect, while PAHs were maximum in industrial transect followed by EW. Concentrations of marker plasticizers (DnBP and DEHP) released during EW activities were significantly higher (p < 0.05) in Bangalore than in other cities. Toxic equivalents (TEQs) due to dl-PCBs was maximum in the EW transect and PCB-126 was the major contributor. For both youth and adult, the highest estimated inhalation risks for dl-PCBs and plasticizers were seen at the EW transect in Bangalore, followed by Chennai and New Delhi.

Socio-economic impacts of the COVID-19 pandemic on waste bank closed-loop system in Surabaya, Indonesia.

The COVID-19 pandemic has caused most waste recycling activities to be terminated due to several factors, such as concerns about the spread of coronavirus through the collected solid waste. This study investigates the socio-economic impact of the situation of the closed-loop system of solid waste recycling. Several recommendations for tackling this problem are presented in this research. Primary data collection for the waste bank and informal recycling sector was carried out in the eastern part of Surabaya during large-scale social restrictions. In-depth interviews were conducted with waste bank customers, waste bank unit representatives and the informal recycling sector to understand the pandemic's socio-economic impact on the closed-loop system. Results show that this pandemic has significant impacts on individuals and stakeholders engaged in waste recycling activities. Customers of waste banks, who mostly belong to low-income communities, mentioned that the waste bank closure gave rise to social and economic problems, such as increasing unmanaged solid waste and decreasing income. This result also applied to the informal recycling sector. The government can use the recommendations in this study to generate related policies, such as enforcing the health protocol within solid waste management to keep the recycling system in place and the business alive.

Urban Informatics in Sustainable Waste Management: A Spatial Analysis of Korea’s Informal Recycling Networks

Large-scale informal recycling networks often emerge among developing economies in response to the challenges of modern urban waste accumulation. South Korea, despite its highly industrialized, developed economy, still maintains an extensive informal recycling sector made up of networks of local junk shops and individual waste pickers. As cities’ large data sources have become more widely available, the use of urban informatics in sustainable smart waste management has become more widespread. In this paper, we use geographic information system (GIS) analysis in order to uncover patterns within Korea’s informal recycling system, looking at the relationship between population demographics, waste levels, and urban planning with the prevalence of junk shops across Korea. We then interviewed junk shop owners, urban planning researchers, and government officials in order to better understand the factors that led to the coexistence of the country’s informal and formal systems of waste management and how junk shops have changed their operations over time in response to recent developments in cities’ urban fabrics. We conclude by giving suggestions for how the usage of urban informatics could increase the efficiency and sustainability of the country’s waste management systems, while also discussing the possible pitfalls of using such existing datasets for future policy decisions.

E-Waste Management in Asia Pacific Region: Review of Issues, Challenges and Solutions

Proper management of used electrical and electronic equipment (EEE), known as e-waste, is causing a significant challenge for many countries around the world. United Nations estimate that the world generated 53 million metric tonnes (Mt) of e-waste in 2019, mostly from the Asian region. Poor handling of e-waste can cause severe environmental and human health issues due to the toxic compounds in e-waste. E-waste also contains valuable metals worth recovering. Environmentally sound management (ESM) of e-waste is either absent or limited in developing countries due to the informal recycling sector’s dominance. Many countries are in the process of developing regulations based on extended producer responsibility (EPR) concepts. This paper aims to review the current status, issues, and challenges faced by Asia Pacific countries and suggest a way forward for the ESM of e-waste.

The Integration of Recycling Cooperatives in the Formal Management of Municipal Solid Waste as a Strategy for the Circular Economy—The Case of Londrina, Brazil

In many developing countries, the informal recycling sector is responsible for reducing the amount of waste in landfills and supplying the needs of recycling industries. In the context of municipal solid waste (MSW) management, considering that developing countries aim to implement circular economy (CE) actions, it is essential to ensure the inclusion of waste pickers (catadores) in an adapted CE structure. This study analyzes the integration of recycling cooperatives in the formal management of municipal solid waste with recyclable potential (MSWRP) of a medium-sized municipality in Brazil, with the objective of ascertaining the contributions of cooperatives in an adapted CE structure and, at the same time, identifying a cooperative that can be used as a benchmarking option for other cooperatives, especially in relation to their organizational and operational practices. The results indicate that from this integration, cooperatives have legal responsibility in the management of MSWRP, resulting in the professionalization of its members and increasing their productivity. The results also revealed that the implementation of the CE in developing countries is, in a sense, conditioned to the performance of the informal sector in the recycling chain and, in addition, that the inclusion of cooperatives in the formal sector of MSWRP management can improve the rates of a municipality.

Recent evolution of the informal recycling sector in Argentina within the 'popular economy': Measuring its impact through a case study in Tandil (Buenos Aires).

The integration of the informal recycling sector into formal waste management systems is imperative to the implementation of the circular economy in the Global South. In Argentina, after the 2001 crisis, some large cities such as Buenos Aires greatly improved their informal recycling sector integration. In medium-size cities from the rest of the province, this was not the case. However, the formation of a national coalition between different sectors of what is now called the 'popular economy' forced the enactment, in the context of a new crisis, of a Social Emergency Law, which includes a Complementary Social Salary equivalent to half the minimum wage, among its main features. In this paper, we recap these recent changes and we use the InteRa framework in a case study to measure how, along with academic and civil society support actions, they influenced the informal recycling sector integration in an intermediate city of Buenos Aires province. Our results show that the inclusion of the informal recycling sector improved rapidly after the availability of the Complementary Social Salary. Nevertheless, we registered a hard-to-overcome stagnation in some indicators of the InteRa framework, related to the weak engagement of the local municipal government with the informal recycling sector. Importantly, the advent of the Complementary Social Salary was not reflected in any indicator because there is no specific action related to this aspect in the InteRa framework. This may give an insight into future methodology improvement.

Building a circular plastics economy with informal waste pickers: Recyclate quality, business model, and societal impacts

The circular economy rationale is increasingly promoted as a means to move from a global plastic waste dilemma to a plastics economy that is aligned with the principles of sustainable development. However, any such effort will have to account for the socio-economic settings in low-income and middle-income countries of the global south which are the main entry points of mismanaged plastic wastes into the environment. Since waste management and recycling in these economies are characterized by a great degree of informality, there is an urgent need to find models for partnering with the informal recycling sector in an effective, scalable, and sustainable manner. In this work, we present the case of a for-profit company located in Nairobi, Kenya, that operates on the interface between formal and informal by processing post-consumer plastics sourced from local waste pickers through a fair-trade-like business model.Economic incentives, trust building measures, and a general willingness to learn and adapt were identified as prerequisites for establishing accountable supplier-buyer relationships. The combination of informed material pre-sorting by the individual waste picker and subsequent industrial scale sorting and washing resulted in recyclates that were comparable to commercially available benchmark recyclates from the sophisticated formal recycling system of a high-income country in terms of both composition and selected engineering properties. High-quality mechanical recycling of plastic wastes under informal conditions seems feasible and may even come along with socio-economic benefits for marginalized waste pickers when suitable modes of cooperation are put in place.

Assessment of municipal solid waste selective collection scenarios with geographic information systems in Bolivia

The analysis of municipal solid waste (MSW) selective collection (SC) scenarios is compulsory for planning future policies and actions towards circular economy. The use of geographic information system (GIS) is appropriated for obtaining reliable data about SC yields and management costs. However, in low-middle income countries, advanced assessments are difficult to introduce due to the lack of technical knowledge, financial support and the presence of the informal recycling sector. This research aims to assess the main potentialities of the introduction of SC systems in a Bolivian developing city taking into account the informal SC system in place. The study was conducted with QGIS3.8 software in order to evaluate the main advantages of the implementation of formal and informal recycling chains. Results reported that, comparing the implementation of formal SC of MSW with the scenario that considered the inclusion of the informal recycling, the activity of waste pickers allows reducing the expenses of about 10%, increasing the recycling rate of about 3.5%, and reducing the distances traveled with compactor trucks of about 7%. It means that, the annual path traveled by the collection trucks for gathering about 16,000ty−1, is reduced by 2734kmy−1, reducing the waste disposed to landfill of about 543.6ty−1 and the expenses of about €59,000 per year. The presentation of these results to policy-makers can support decision-making boosting the implementation of recycling activities including waste pickers. The study provided a contribution to the scientific literature assessing the main challenges and opportunities for implementing the circular economy in developing regions.

A Mini‐Review of E‐Waste Management in Brazil: Perspectives and Challenges

AbstractThe accelerated production and replacement of new electrical and electronic equipment demonstrates a tendency for the proportional increase in the generation of e‐waste. Developing countries experience similar social and environmental consequences from this trend, which compounds the other challenges associated with the already poor solid waste management in these regions. Moreover, the dangerous composition of some e‐waste amplifies the problems related to managing these materials. This mini‐review presents a brief overview of e‐waste management in Brazil, including technical aspects, scientific studies, and the challenges ahead. With the Brazilian National Policy of Solid Waste already in place, technical and scientific studies endorse measures that range from incorporating the informal recycling sector into the e‐waste management sector to encouraging the expansion of the recycling industry. All such actions, combined with an intensified commitment of electronic equipment manufacturers to reverse logistics, can improve e‐waste management in Brazil.

Assessing young consumers' awareness and participation in sustainable e-waste management practices: a survey study in Northwest China.

The massive generation of electronic waste (e-waste) and the informal recycling of e-waste are serious concerns in China. As a hazardous waste stream, e-waste calls for sustainable management practices to avoid adverse effects on environment and health. However, consumers' awareness and active participation are needed to make e-waste management successful. Therefore, this study is an exploratory attempt to investigate young consumer awareness, knowledge, and participation in sustainable e-waste management practices. Meanwhile, the study reviews the current situation of e-waste recycling, its related legislative framework, and practices in China. The survey revealed that the respondents have keen environmental consciousness, while they have low awareness about e-waste-related rules and regulations, recycling programs, and the formal and informal recycling sector. The findings provide valuable insights for practitioners in order to promote environmental awareness and sustainable e-waste management practices among young consumers in China.

The use of ICT in the informal recycling sector: The Brazilian case of Relix

AbstractThis paper aims to understand the uses of technology in the informal recycling sector. We investigated the case of Relix, in northeast Brazil. The Relix project consists of cultural and educational interventions that promote recyclable waste picking and provides a mobile application to connect the local population to waste pickers. Methodological procedures included semistructured interviews with different groups of stakeholders. We adopted the Multilevel and pluralistic conceptual framework to analyze the groups according to the use of technology and perceptions in which they live based on context, process, and content. Results demonstrate that although the mobile application (app) can help waste pickers and the population to connect, it cannot single‐handedly promote any meaningful changes in the lives of people. Additional actions should be taken. This study has two important contributions. First, it describes how the Information and Communication Technology (ICT) can improve working conditions and create more innovative and equitable environments. Second, it enriches the theoretical discussion on the use of technology in social practice and the advances of applying a theoretical framework in the context of informal recycling.

Determining Recycling Fees and Subsidies in China’s WEEE Disposal Fund with Formal and Informal Sectors

At present, most of China’s waste electrical and electronic equipment (hereafter referred to as WEEE) flow into the informal recycling sector, which has no official disassembly certification. To regulate the WEEE recycling industry, the policy of the WEEE disposal fund has been implemented to levy recycling fees from producers and subsidize the formal recycling sector. This paper aims to solve the challenging problem of how to optimize recycling fees and subsidies. We first study the competition between the formal and informal sectors, and construct the game models of the dismantling and refurbishing processes. Based on the equilibrium outcomes, we then examine the impact of the disposal fund on producers, as well as the formal and informal recycling sectors. With the goal of maximizing social welfare and maintaining a balanced budget for the disposal fund, we study the optimal recycling fee levied on producers and the corresponding subsidy provided to the formal sector. Social welfare is a function of producer and formal-recycler profits, consumer surplus, and the negative externality caused by informal dismantling and refurbishing, such as environmental pollution and safety problems. Results show that the use of subsidy can increase the acquisition quantity of used products in the formal sector, but the increase will slow down with higher subsidy. If the recycling fee that producers are charged is small, social welfare will be improved. In addition, as the fee is increased, social welfare will rise first and then fall. As such, any excessive increase in recycling fees should be avoided.

Efficiency of packaging waste management in a European Union candidate country

This paper provides a quantitative and qualitative evaluation of Serbia’s packaging waste management system, which is based on the Extended Producer Responsibility scheme (EPR). Additionally, it identifies and discusses the major challenges faced by the system. This paper strives to shed some light on the challenges posed by the implementation of an advanced and highly institutionalized approach to packaging waste management in the context of a European Union candidate country. The analysis indicates that Serbia is a country with an evolving administrative and institutional approach to packaging waste management, which can reach national recovery targets through its EPR system. The main challenges that must be addressed for the system to continue progressing in order to meet European Union’s recovery targets are: (i) increase the low supply of recovered recyclables from the municipal solid waste stream, (ii) close loopholes affecting recycling industry and work of National Recovery Organisations, and (iii) formalization of informal recycling sector’s role within the formal packaging recovery framework.

IS THERE A FUTURE FOR THE INFORMAL RECYCLING SECTOR IN URBAN CHINA?

This article constitutes a comprehensive overview that summarises first-hand research findings obtained by the authors through scientific engagement with the informal recycling sector (IRS) in mainland China over the past six years. During this research period, especially between 2013 and 2016, we found several indications that the working environment of informal stakeholders in urban China was worsening. Among these challenges the IRS faces, two are especially noteworthy – a decline in profits and increasing regulatory pressure from the government. In our analysis we primarily focus on the segment of the IRS that deals with collection and pre-processing (sorting, separating, cleaning, bulking, refurbishment, material extraction) of recyclables and Waste Electrical and Electronic Equipment (WEEE) in urban China. Our results indicate that despite their strong prevalence in this domain, informal actors are increasingly subjected to falling profit margins and regulatory pressure. However our results also shows that the IRS has in the past responded to both challenges rather effectively and thus may be able to maintain its presence in urban Chinese Waste Management (WM).

PREDICTION OF E-WASTE GENERATION BASED ON GREY MODEL (1,1) AND MANAGEMENT IN BOTSWANA

This paper seeks to evaluate the quantities of e-waste in Botswana from 2000-2019, with a view towards formulating an effective and sound e-waste management system. Due to a lack of complete historical records on e-waste quantity and quality, this was achieved by the Grey Model GM(1,1) forecasting method. Our estimations indicate that an average weight of about 293.18 tons of e-waste will be generated in 2019 in the country. Considering an economic lifespan of between 3 and 10 years, more e-waste is expected to be produced annually in the country. This paper also highlights key societal factors influencing successful implementation of a sound e-waste management system. These include the introduction of legislation dealing specifically with e-waste, establishment of formal take-back systems, integration of the informal recycling sector into the formal recycling sector, innovative technologies and investment on e-waste management activities. An effective management system of waste from this sector should involve consideration of the toxicity and value of some of the components and materials of electrical and electronic equipment (EEE) and the prevailing inappropriate disposal practices for such potentially toxic materials.
