Hepatitis C Virus (HCV) is a significant health problem worldwide, especially in developing countries. Medical municipal waste pickers are at higher risk of exposure to infectious viral diseases. The current study aimed to explore HCV infection in different waste collectors. The objective of the current study was to investigate the incidence of HCV infection and associated risks among the waste collectors of five districts of Malakand Divisions and Bajaur district (old Bajaur agency) Khyber Pakhtunkhwa, Pakistan. During the study period (May-December 2017), blood samples were collected from 300 waste handlers and tested for anti-HCV antibodies using the ICT method. The results obtained from the data were analyzed statistically using SPSS 20 version. In this study, we included 300 males aged 9 to 76 years, which means 27.31 ± 11.9 years. The prevalence of HCV was 3.3% (10/300). Among the positive cases, HCV infection was slightly higher in married persons than in unmarried (3% vs. 0.33%, %, PV < 0.01, odds ratio 4.73, 95% CI =2.2-9.8). A high infection rate was reported in waste scavengers from the district Swat, followed by those in the Bajaur district. Needle prick injuries and barehanded practices were the significant risk factors for infected cases. Our findings highlight the need for personal protective equipment. It is suggested that all garbage collectors should be trained in handling waste to reduce infection.

Solid waste management in low- and middle-income countries like India faces significant challenges due to the increasing waste generation that surpasses the current capacity. Therefore, the informal waste sector (IWS) is more vital than ever in handling consumer waste alongside municipal solid waste management (SWM) systems. However, the integration of the IWS into formal waste management systems remains unresolved due to adverse social and economic conditions. This study focuses on identifying the root causes that hinder the integration of the IWS in India\'s waste management system, using the city of Chennai as a case study. Adopting an institutional perspective, we analyse the institutional landscape of the waste management system, considering both formal rules (in policy documents) and informal rules (i.e., social norms and routines). The institutional network analysis reveals a significant misalignment in perceptions among governance levels concerning the integration of the IWS. The study shows a considerable gap between rules-in-form and rules-in-use, leading to 1) Preclusion of waste pickers in collecting door-to-door source-segregated waste (i.e., recyclables). 2) Unfair pricing in transactions with small aggregators. 3) Lack of ID cards for waste pickers. These barriers are ultimately rooted in caste discrimination, misalignment between governance levels, and the exclusion of waste pickers in the policymaking process. In conclusion, understanding and rectifying the institutional gaps and discriminatory practices are essential steps towards effectively integrating the IWS in India\'s waste management system, promoting a more inclusive and sustainable approach to waste management.

Waste pickers, who work with the collection of recyclable materials in search of a source of income, are subject to various risks and diseases that are very well researched. The aim of this systematic review was therefore to identify and analyze the results of epidemiological research on waste pickers over the last 20 years as well as to investigate the geographical distribution and quality of these studies. The studies were selected from the literature by creating search keys with representative keywords in different databases. This systematic review exceptionally includes research qualified according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. In total, 61 epidemiological studies with waste pickers were found in 15 different countries, with the largest number of studies carried out in the American continent compared to the African and Asian, respectively. Regarding the quality, 91.80 % were classified as excellent and 8.20 % as good. Although the results show a significant number of epidemiological studies with waste pickers, demonstrating scientific evidence, that there is still a lack of research focusing on waste pickers in different work scenarios, from different health perspectives and in different parts of the world, and it is not possible to highlight the trends in health research for this profession.

There are almost 8 billion people on the planet with every single one of them producing some type of waste. The cost of recycling and money made by selling recyclable products has created a strong foundation for informal waste picking to exist. Waste pickers sort through garbage to find recyclable material; it is estimated that there are around 20 million waste pickers worldwide. In 2022, I went to experience life as a waste picker in Brasilia, Brazil for a day to understand issues that may continue to exist in this informal industry. I worked in a triage center and used this experience to inform my autoethnography; even though I have worked in waste picker research for almost a decade, this experience led to a different conclusion. The most interesting issue that I found while working as a waste picker was the lack of uniformity in waste picking, which led to people working on the streets or in co-op triage centers. This population is vulnerable which is worsened from exposure to hazards by nature of the informal environment; this situation contributes to ongoing poor working conditions through lack of governmental oversight, policy development, and change. Ultimately, informality needs to be addressed.

The aim of this cross-sectional study was to compare workplace conditions and metal exposures in 431 waste pickers who worked nearby at the Estrutural Dump in Brasilia utilizing hair (n = 310) and nail (n = 355) as matrices of exposure. Waste pickers were grouped according to their workplace (open waste dump: G1 and sorting plants: G2). Hair and nail samples were collected and analyzed using ICP-MS. The work duration in the facilities was significantly different between the groups with averages of 16.46 (8.48) yrs and 9.26 (6.28) yrs for hair donors in G1 and G2, and 15.92 (7.72) yrs and 8.55 (5.77) yrs for toenail donors in G1 and G2, respectively. The arithmetic means (μg/g) of cadmium, copper, lead, and manganese in hair were significantly higher in G2 (0.076 ± 0.133; 19.61 ± 18.16; 2.27 ± .56 and 3.87 ± 5.59, respectively) compared to G1 (0.069 ± 0.235; 15.72 ± 15.18; 1.72 ± 4.04 and 3.65 ± 5.5, respectively). Concentrations of arsenic, barium, cadmium, copper, cobalt, lead, manganese, and molybdenum in nail were significantly higher in G2 (0.57 ± 0.39; 22.74 ± 42.06; 0.1 ± 0.08; 22.7 ± 51.60; 0.48 ± 0.45; 4.69 ± 9.43; 19.07 ± 20.75; 1.80 ± 1.76, respectively) compared to G1 (0.40 ± 0.28; 15.32 ± 22.31; 0.08 ± 0.11; 11.91 ± 16.25; 0.37 ± 0.37; 3.94 ± 15.04; 13.01 ± 19.08; 1.16 ± 1.80, respective. Our findings suggest that the studied population was exposed to toxic metals and indicates the need for chemical exposure prevention policies to monitor chemical risk exposures in waste pickers.

The National Health Protection (NHP) of Indonesia is a pro-poor social health insurance as the government pays the monthly premium for the poor. A waste picker is classified as an urban poor group needing affordable or free access to health care. This study explores the extent to which the NHP protects the health of waste pickers and provides them with quality health care. For this mixed-method study, 342 waste pickers completed the survey, 40 engaged in interviews, and 15 participated in Natural Group Discussions. The study found that 20% of waste pickers were not enrolled in NHP due to issues such as incorrect validation of poverty, discrimination, illegal fees, nepotism, unaffordable premiums, and lack of interest in purchasing the health plan. Among those who were enrolled, waste pickers expressed satisfaction with the health care they received and the behavior of the staff. However, they did criticize certain aspects such as waiting times, service gaps between full-paying and subsidized patients, suspicion of the quality of medicines, complicated medical administration procedures, and inflexibility of the capitation system. The study concludes that despite the NHP, poor groups remain vulnerable to accessing free health care.

Plastic waste circularity is a priority at a global level. Sustainable development goals (SDGs) set the ways to go, and the circular economy principles underlined the \'green\' strategies to be employed. However, in practice, there is still much to do, especially in developing countries, where open burning and open dumping still represent the common way of plastic waste disposal. This review aims to analyse current plastic waste circular approaches in low-middle income settings. Seven countries were selected based on the economic level and data availability from the authors, and analysed to collect and critically discuss the actions implemented at a city level. Examples of waste minimization and recycling strategies, selective collection systems and public campaigns are reported from Africa, Asia and Latin America. First, a background analysis related to physical and governance aspects of municipal solid waste management systems of the chosen settings was conducted. The assessment was focused on the treatment processes or minimization actions. Then, the applicability of the projects to achieve the SDGs was commented on. The outcomes of the research underline the need to: (1) scale up small-scale and pilot projects, (2) disseminate good practices in more low- to middle-income settings, (3) create synergies among international partners for further replications in cities. Urgent solutions to plastic waste pollution are needed. The review presented practical actions to be implemented now to boost plastic waste circularity in developing cities.

Numerous garbage dumpsites worldwide have been closed down to address the safety, health and environmental hazards facing waste pickers, such as potential landsides, diseases and pollution. As a result, the environment surrounding the (former) waste pickers may have been safer and cleaner. While the closure of garbage dumpsites may be an act of social justice to protect waste pickers, however, in some cases, the incomes and living standards of former waste pickers who continue to reside at these sites have been aggravated. Drawing on critical theory, and using observations and interviews, this case study examined the post-dumpsite-closure situation of Payatas in the Philippines. This study augments previous research on critical urban and regional studies through the presentation of a meta-critical theory by expanding, critiquing and reconceptualizing critical theory to address the problematic post-dumpsite situation created through the closure of the dumpsite.

Waste plays an essential role during the COVID-19 crisis. This includes increased attention to the amount of waste produced, concerns with how hazardous materials are discarded and handled, or unease that sustainability and recycling efforts are derailed. However, there is a human side to waste: the people who work directly with these materials. Waste pickers are the men, women, and children around the world who rely on tossed away items for their livelihoods. Across dynamic and generally informal networks, waste pickers collect, transport, and separate our discarded materials. They are recyclers, entrepreneurs, and a key component of solid waste management systems in many countries. However, they are also subject to discrimination and unsafe working conditions. The pandemic has shed light on the nuances between vulnerability and opportunity for waste pickers. This intervention considers economic and societal structures during and beyond COVID-19 to highlight underlying concepts of health, hygiene and sustainability and how these may shape experiences of waste pickers.

In the context of the coronavirus disease 2019 (COVID-19) pandemic, compliance with government regulations is a tremendous challenge in the effort to curb the viral transmission. The fact that specific communities and people across the world continue to ignore government regulations of COVID-19 is a crucial issue to address. Researchers sought to examine the political psychological and sociocultural determinants of adherence to COVID-19-related law and policy measures among waste pickers in a sub-urban slum community in Iran. A cross-sectional survey of 362 waste pickers from two municipalities in the countryside of Tehran, Iran, was conducted between January and May 2022. Multiple regression analysis was used to predict the significant difference between the direct or indirect effects of political psychological and sociocultural variables on compliance with COVID-19 emergency measures. Confidence intervals were estimated using the bootstrap method. The findings supported the proposed model. The results indicated that political ideology (β = - 0.13, 95% CI - 0.29 to 0.02), individualism worldview (β = - 0.14, 95% CI - 0.32 to 0.07), fatalism (β = - 0.18, 95% CI - 0.40 to 0.04), health literacy (β = 0.16, 95%CI - 0.05 to 0.37) and prosociality (β = 0.09, 95%CI 0.03-0.13) exert an indirect effect on compliance with the COVID-19 emergency measures through both trust in government and trust in science and scientific community. This study has implications for authorities in ensuring adherence to governmental orders for COVID-19 outbreak. A democracy-based and human rights-based approach and a flexible framework for proceeding more equitable COVID-19 legal and government regulations is critical to an effective and acceptable health response to COVID-19. Instituting slum emergency planning committees, incorporating the informal providers into all pandemic response plans in every urban informal settlement and providing an immediate guarantee of payments to waste packers will be indispensable.
