“…Countries in Line with SDGs 5.1. Latin America Despite the advances in waste management in Latin America and the Caribbean (LAC), which is made up of 48 countries/economies [214], the region still faces many challenges due to the existence of open and uncontrolled sanitary landfills (33%) and low rates of recovery of waste fractions (<4%) in treatment of municipal solid waste [215,216]. Particular attention is required in rural areas which are exposed to severe environmental pollution problems and agricultural activities and industries installed in their surroundings.…”

“…In the same country, the Law of Extended Responsibility of the Producer and Promotion of Recycling (REP; Law 20920) was enacted in 2016 [220]. Its main objective is to establish an industry that takes responsibility for its products through the prevention of waste generation and its recovery and recycling [216]. Figure 7 illustrates that Chile has the lowest percentage of generated plastic in the region, followed by Cuba and the Dominican Republic, while the countries with the highest generation of plastic are Honduras, Argentina, and Guatemala.…”

Rural areas are exposed to severe environmental pollution issues fed by industrial and agricultural activities combined with poor waste and sanitation management practices, struggling to achieve the United Nations’ Sustainable Development Goals (SDGs) in line with Agenda 2030. Rural communities are examined through a “dual approach” as both contributors and receivers of plastic pollution leakage into the natural environment (through the air–water–soil–biota nexus). Despite the emerging trend of plastic pollution research, in this paper, we identify few studies investigating rural communities. Therefore, proxy analysis of peer-reviewed literature is required to outline the significant gaps related to plastic pollution and plastic waste management issues in rural regions. This work focuses on key stages such as (i) plastic pollution effects on rural communities, (ii) plastic pollution generated by rural communities, (iii) the development of a rural waste management sector in low- and middle-income countries in line with the SDGs, and (iv) circular economy opportunities to reduce plastic pollution in rural areas. We conclude that rural communities must be involved in both future plastic pollution and circular economy research to help decision makers reduce environmental and public health threats, and to catalyze circular initiatives in rural areas around the world, including less developed communities.

“…In this context, improving the eco-efficiency of MSW management is essential ( Romano and Molinos-Senante, 2020 ; Sarra et al, 2020 ). Whereas efficiency assessment focuses on the economic performance of MSWSPs ( Yang et al, 2018 ), eco-efficiency assessment embraces both economic and environmental variables in the performance evaluation ( Llanquileo-Melgarejo and Molinos-Senante, 2021 ). Recently, performance of MSWSPs has been extended to evaluate their eco-efficiency considering both recyclable waste and unsorted waste ( Sarra et al, 2019 ).…”

Factors influencing eco-efficiency of municipal solid waste management in Chile: A double-bootstrap approach

et al. 2022

Improving eco-efficiency in the provision of municipal solid waste plays an important role for a sustainable economy. Eco-efficiency of municipal solid waste service providers (MSWSPs) has been generally assessed using the conventional data envelopment analysis (DEA) method. However, this approach is sensitive to data noise and has no statistical properties. To overcome these limitations, in this paper, we adopt the double-bootstrap DEA model to derive robust eco-efficiency scores. This nonparametric method allows conducting statistical inference to explore environmental factors affecting the eco-efficiency of MSWSPs. The empirical approach focused on a sample of 298 MSWSPs in Chile, a middle-income country whose policies for promoting waste recycling are incipient. The results indicated that based on the bias-corrected eco-efficiency scores, the potential saving in costs and unsorted waste could be up to 37.8% on average to generate the same level of output (recycled waste). The findings showed that dealing with data noise and uncertainly is of great importance when conducting benchmarking analysis. The region where the municipality is located, tourism, population density and waste per capita are environmental variables that significantly influenced eco-efficiency of Chilean MSWSPs. Several policy implications are discussed based on the findings of this study.

“…Solid waste management (SWM) constitutes a challenging and prevalent issue for authorities due to health problems wrought by improper waste management and the various related atmospheric issues, such as odour pollution, air pollution, and soil degradation (Ferronato et al 2021). In developed countries with growing populations and economies, there has been a steady increase among both urban and rural populations in the level of waste generation (Kamarehie et al 2020;Llanquileo-Melgarejo & Molinos-Senante 2021). This increase has made researchers highly concerned about the sustainable management of municipal solid waste (MSW) (Xiao et al 2020).…”

Yard waste is one of the key components of municipal solid waste and can play a vital role in implementing zero-waste strategy to achieve sustainable municipal solid waste management. Therefore, the objective of this study is to predict yard waste generation using the grey theory from the predicted municipal solid waste generation. The proposed model is implemented using municipal solid waste generation data from the City of Winnipeg, Canada. To identify the generation factors that influence municipal solid waste generation and yard waste generation, a correlation analysis is performed among eight socio-economic factors and six climatic factors. The GM (1, 1) model is utilized to predict individual factors with overall MAPE values of 0.06%−10.39% for the in-sample data, while the multivariable GM (1, N) grey model is employed to forecast the quarterly level of municipal solid waste generation with overall MAPE values of 5.64%−7.54%. In this study, grey models predict quarterly yard waste generation from the predicted municipal solid waste generation values using only twelve historical data points. The results indicate that the grey model (based on the error matrices) performs better than the linear and nonlinear regression-based models. The outcome of this study will support the City of Winnipeg's sustainable planning for yard waste management in terms of budgeting, resource allocation, and estimating energy generation.
