Abstract
The growing tendency towards 'urbanization' is promoting an increase in resource consumption and waste generation, which requires proper waste separation management with active participation of the population. To this end, it is essential to know the personal modifiable factors that predict recycling. The primary aim of the present study is to develop and evaluate the psychometric properties of a Spanish language questionnaire designed to measure determinants of household waste separation for recycling purposes (ReDom Questionnaire). A cross-cultural adaptation, translation and psychometric evaluation was undertaken of an extant questionnaire originally developed in Swedish, and the resultant Spanish questionnaire was then subjected to reliability and validity testing. The questionnaire was developed using survey data from 759 respondents and 33 participants performed the retest to assess reliability. The resultant 'ReDom Questionnaire' is composed of three factors that draw on relevant elements of the COM-B framework: motivation (seven items), physical opportunity (three items) and social opportunity (three items). The accuracy of the scores is adequate both in terms of internal consistency (factorial weights >0.60; comparative fit index = 0.994; root mean square error of approximation = 0.049; root mean square residual (RMSR) = 0.053) and reliability (Pearson correlation >0.65; Cronbach's alpha >0.75). In conclusion, the Spanish ReDom Questionnaire showed adequate psychometric properties and appears useful for assessing the determinants of household waste separation.

Abstract
Given the challenges of urbanization and rapid resource depletion, policymakers have been compelled to abandon the old sequential paradigm of "take-make-use-dispose" to a circular approach that prioritizes preservation of natural resources. The circular economy represents a sustainable management concept that focuses on reducing, recovering, reusing, and recycling waste. While significant strides have been made in implementing circular economy principles in various industries such as automotive, electronics, and construction, particular attention has been given to the water and wastewater domains due to imbalances in water resources. Here we review the global progress of circular economy adoptability in the water and wastewater domains, considering technical, environmental, economic, and social perspectives. It assesses the current state of circular economy integration in the wastewater domain worldwide and presents approaches to promote and accelerate its adoption. The study critically examines the principles of waste management, known as the 6Rs (reclaim, restore, recycle, reduce, recover, reuse), in order to formulate effective strategies for integrating circular economy practices in the water and wastewater domains. Additionally, the study provides an overview of existing research conducted on different aspects of circular economy. Finally, the study analyzes the challenges and opportunities associated with implementing circular economy principles in the water sector.

Abstract
Purpose
In the transition towards circular economy and sustainable development, effective implementation of extended producer responsibility (EPR) legislation is crucial to prevent plastic-waste generation and promote recycling activities. The purpose of this study is to undertake a qualitative analysis to examine recent EPR policy changes, implementation, barriers and enabling conditions.
Design/methodology/approach
In-depth interviews and group discussions with key stakeholders were undertaken to derive the barriers and facilitators of EPR implementation. Based on opinions and insights from a wide range of participants, this study identified a number of key issues faced by various parties in implementing EPR in India.
Findings
Stakeholders agree on a lack of clarity on various policy aspects, such as mandatory approval of urban local bodies, registration of recyclers/waste processors and consistency in the definition of technical terms. This paper provides useful policy inputs to address these challenges and to develop comprehensive EPR policy systems. More consultation and deliberation across various stakeholders is required to ensure the policies are effective.
Practical implications
India’s plastic-waste generation has increased at a rapid pace over the past five years and is expected to grow at a higher rate in the future. This research provides implications for policymakers to formulate coherent policies that align with the interests of brand owners and recyclers. Clear policy suggestions and improvements for effective plastic-waste management in India are also outlined.
Originality/value
This paper, based on a qualitative approach, contributes to research on plastic-waste management by integrating the perspectives of all EPR-policy stakeholders in India.

Abstract
To reduce global greenhouse gas emissions in order to limit global warming to 1.5°C, individuals and households play a key role. Behavior change interventions to promote pro-environmental behavior in individuals are needed to reduce emissions globally. This systematic literature review aims to assess the a) evidence-based effectiveness of such interventions and b) the content of very successful interventions without limiting the results to specific emitting sectors or countries. Based on the "PICOS" mnemonic and PRISMA statement, a search strategy was developed, and eligibility criteria were defined. Three databases (Embase, PsycInfo, and Web of Science) were searched to retrieve and review potential literature. As a result, 54 publications from 2010 to 2021 were included in the analysis. The results show that most interventions only have small positive effects or none at all. A total of 15 very successful interventions focused on the sectors of mobility, energy, and waste and incorporated improved (infra-) structures, education, feedback, enablement or made the sustainable option the default. Six evidence-based recommendations for content, timing, and setting are deducted and given for interventions on enhancing pro-environmental behavior (PEB). In summary, although the various interventions and intervention types to promote PEB differ in their effectiveness, very successful interventions have common elements. Future research should focus on high-/low-impact and high-/low-cost behavior to develop interventions that aim at high-impact but low-cost behavior changes, or avoid low-impact but high-cost behavior.

Abstract
Plastic pollution is ubiquitous in terrestrial and aquatic ecosystems. Plastic waste exposed to the environment creates problems and is of significant concern for all life forms. Plastic production and accumulation in the natural environment are occurring at an unprecedented rate due to indiscriminate use, inadequate recycling, and deposits in landfills. In 2019, the global production of plastic was at 370 million tons, with only 9% of it being recycled, 12% being incinerated, and the remaining left in the environment or landfills. The leakage of plastic wastes into terrestrial and aquatic ecosystems is occurring at an unprecedented rate. The management of plastic waste is a challenging problem for researchers, policymakers, citizens, and other stakeholders. Therefore, here, we summarize the current understanding and concerns of plastics pollution (microplastics or nanoplastics) on natural ecosystems. The overall goal of this review is to provide background assessment on the adverse effects of plastic pollution on natural ecosystems; interlink the management of plastic pollution with sustainable development goals; address the policy initiatives under transdisciplinary approaches through life cycle assessment, circular economy, and sustainability; identify the knowledge gaps; and provide current policy recommendations. Plastic waste management through community involvement and socio-economic inputs in different countries are presented and discussed. Plastic ban policies and public awareness are likely the major mitigation interventions. The need for life cycle assessment and circularity to assess the potential environmental impacts and resources used throughout a plastic product’s life span is emphasized. Innovations are needed to reduce, reuse, recycle, and recover plastics and find eco-friendly replacements for plastics. Empowering and educating communities and citizens to act collectively to minimize plastic pollution and use alternative options for plastics must be promoted and enforced. Plastic pollution is a global concern that must be addressed collectively with the utmost priority.

Abstract
The implementation of waste selective collection (SC) schemes in low-income countries is a challenge although it is one important way for improving environmental sustainability. The inclusion of the population is necessary for gaining effective results, and social surveys are support methods for understanding citizens' involvement and behaviour. The aim of the research is to assess the support of the citizens concerning the formal and informal recycling in a low-middle income country. The study presents a questionnaire survey conducted in 2018 in La Paz, Bolivia, where 774 citizens were interviewed for evaluating their support to the formal and informal SC systems. Two questionnaires were submitted to two different users' categories: users of the formal recyclable waste gathering points; and citizens of the neighbourhoods. Evidence of the survey shows that about 8% of the population supports the formal SC while about 48% are used to selecting their waste at home. About 79.2% of them bring the waste to the informal recycling shops or provide it to waste pickers, throwing the waste into or nearby the mixed containers in order to facilitate their collection. This research demonstrates how social inclusion is important for planning recycling systems within a developing big city, starting from the SC. Results suggest that the informal sector can be an effective means for improving the recycling behaviour of the citizens. The study can be of interest to stakeholders involved in introducing recycling policies in developing cities where the SC rate is still low, and informal waste collection exists.

Abstract
Across the African continent especially in Nigeria, solid waste disposal has created significant environmental and health issues. Studies on household decision-making on waste disposal choices are insignificant. This study uses the most recent 2018/2019 General Household Survey (GHS) – a national representative sample of 5000 households collected by the Nigerian Bureau of Statistics (NBS) and World Bank – to offer greater insight on the socio-economic drivers of household's decision-making on the choice of alternative refuse disposal systems and how these choices vary across male-headed households (MHHs) and female-headed households (FHHs) in Nigeria. Adopting the Multinomial Logit and Exogenous Switching Treatment Effects Regression (ESTER) models, estimates show that education, family sizes, non-home ownerships, water availability, toilet locations, electricity connections within buildings, geopolitical zones, and urban areas are some determinants of household waste disposal choices which also varies by household types. However, quite a significant number of FHHs are observed to utilize informal refuse disposal systems than the MHHs representing a gender gap in the informal waste usage of 9%. In the counterfactual scenario FHHs average probability of adopting compound (informal) refuse disposal choices, would have increased by 4.2% (decreased by 5.4%) if they had the same socio-economic characteristics as MHHs. These results present some interesting factors related to the heterogeneity of alternative refuse disposal choices the heterogeneous effects of gender on such decisions. The study thus offers some policy inputs on how to ensure a clean and safe environment through proper disposal options.

Abstract
Generation and inadequate management of solid waste constitute a global challenge. Projections for 2050 portend an annual increase of 3.40 billion tons of waste. This study assessed the impact of an environmental education intervention (EEI) aimed at reducing waste generation and fomenting pro-environmental behaviors in an academic public-health institution in Mexico. The EEI was implemented over 20 months using a model of behavior change. Using a mixed-method design (QUAN + qual), baseline and follow-up measurements were performed through electronic questionnaires (n = 754), focus groups (n = 20), and waste quantification. A double-difference model was performed to measure pro-environmental behaviors impact: overall and by sex, age, educational level and function within the institution. Waste quantification was performed using a quartering method and weekly monitoring. The qualitative data were studied through thematic analysis. As a result of the EEI, women reduced their use of multilayer packaging (-15.6 pp, p < 0.05) and frequent use of non-ecological materials (-17.6 pp, p < 0.05). Graduate-level participants reduced their regular and frequent use of these materials (-33.3 pp, p < 0.05, 27.6 pp, p < 0.01), while those with lower educational levels increased their ecological behavior at home (12.1 pp, p < 0.05). Waste generation dropped by 60.1% vis-a-vis the baseline measurement. Our qualitative findings showed a relationship between holding a position of power in the institution and recycling. They also revealed that available infrastructure for separating waste contributed substantially to the observed impact. With actions centered on physical structure, community practice and institutional policy components, the EEI improved the pro-environmental behaviors and perceptions of participants.

Abstract
Behavioral patterns on seeking health are pertinent in terms of how waste is managed. However, informal approach towards waste management has led to poor environmental attitude and pernicious health consequences for many Nigerians. Despite plethora of scientific investigation on waste management, there has been paucity of information on health-seeking behavior and waste management practices among market women, hence the need for this research. The study aimed at assessing the health-seeking behavioral pattern of women traders on waste management in major urban markets in Owerri, Nigeria by identifying the extent of their commitment to sustainable waste management practices, investigating health-seeking behaviors that influence their attitude towards waste management and measuring prevalence of waste-related diseases among them. Data collection for the study involved a cross-sectional survey of 739 women trading in three Owerri major urban markets in line with the study's aim. Results show that motivation to manage waste for disease control was effectively predicted by type of trading item (Omnibus Test: χ2 = 13.871, df = 3, p-value = 0.003); Cochran-Armitage tests of trend show that there is no statistically linear trend between the proportions of understanding the 3Rs and the rankings for methods of seeking health; understanding the 3Rs was not determined by health-seeking method as most methods were with motivation to manage waste discordant (4 out 5 health-seeking methods had negative Goodman & Kruskal's G values); PCA on the prevalence of waste-related diseases had a two-component structure which followed acute and chronic dimensions; vegetable and plastics comprised the highest waste streams with plastics being most reused waste type while government is mainly responsible for waste disposal. The study recommends a knowledge transfer approach in entrenching sustainable waste management practices.

Abstract
China's paper industry development is rapid, but the recycling rate of China's waste paper has been low all the time. Meanwhile, material flow analysis can help determine the flow of waste paper, and life cycle assessment (LCA) is the methodological framework for quantifying greenhouse gas emissions. Therefore, present study integrates these two methods into the model construction of China's waste paper recycling decision system. Present study constructs a benchmark model of China's waste paper recycling decision system in 2017, focusing on the impact of nonstandard waste paper recycling on the economic and environmental benefits of China's domestic waste paper recycling system. This model construction is followed by sensitivity analysis of the relevant parameters affecting the efficiency of the waste paper recycling system. Finally, present study forecasts the system's economic benefits and greenhouse gas (GHG) emissions in the context of integrating and regulating nonstandard recycling vendors. The results show that the economic benefit of China's waste paper recycling in 2017 is approximately 458.3 yuan/t and that the GHG emissions are 901.1 kgCO2eq. The standard recovery rate and nonstandard recovery acceptance rate will both have a significant impact on the system's economic benefits and improve the GHG emissions structure. In the context of integrating nonstandard recycling enterprises and individual recycling vendors, the economic benefits will rise to 3312.5 yuan/t in 2030, while GHG emissions will rise to 942.9 kgCO2eq. Present study can play a certain guiding role for policy makers in formulating waste paper recycling industry specifications and formulating relevant policies.
