Improving Municipal Solid Waste Services: Insights into Efficiency, Productivity, and Recycling in Brazil

Sustainability, Journal Year: 2025, Volume and Issue: 17(6), P. 2519 - 2519

Published: March 13, 2025

This study analyzed the interactions between efficiency, productivity, and policy of recyclable materials recovery in municipal solid waste (MSW) services Brazil, using data from National Sanitation Information System (SNIS) for 199 MSWs, encompassing a balanced longitudinal panel 2013 to 2022. In this context, employed dynamic slacks-based measure (DSBM) model assess intertemporal efficiency productivity MSWs. is an additive extension traditional envelopment analysis, as it does not focus solely on overall operators. Additionally, multiple correspondence analysis (MCA), independent sample tests, generalized estimating equations (GEE) were utilized identify potential among variables interest. The main contribution lies its considering indirect influence operating expenses carry-over, which impacts continuity across periods. Insights results indicated average 61.9% accumulated loss over period. exhibited negative interaction with both MSW operators performing selective collection technological advancement systems. underscores importance integrating field within circular economy framework fostering recycling initiatives. Factors such population density, gross domestic product (GDP), COVID-19 pandemic influenced and, certain aspects, productivity. findings provide insights suggesting that policymakers regulatory agencies should consider these enhance eco-efficiency eco-productivity policies, particularly alignment Sustainable Development Goals (SDGs) current Brazilian legislation.

Water resources, energy, and food are fundamental resources for high-quality regional development. In the process of rapid economic growth, integrating utilization these has become a critical challenge achieving development in Ili River Valley. To explore coordinated status water, (W-E-F) Valley, we constructed comprehensive evaluation indicator system W-E-F system, calculated analyzed level, coupling coordination degree, spatial equilibrium from 2008 to 2020. The results indicate that indicators Valley exhibited an overall upward trend, indicating is moving positive direction. Among them, water subsystem’s showed trend but fluctuated significantly during study period, with excessive proportion agricultural consumption being key factor affecting its Furthermore, energy subsystem slight downward constraints on subsystems. Agricultural surface pollution industrial waste primary factors limiting Meanwhile, due significant attention governments at all levels, been developed rapidly, showing which shows region actively promoting production capacity enhancement initiatives. Additionally, degree remained state coupling, average value between 0.7 1.0, high each resource affects constrains other two. transitioned through phases near coordination, good moderate counties cities tendency evolve towards potential further coordination. subsystems, highest (0.78) smallest disparities, while demonstrated lowest (0.40) largest disparities. There were still issues allocation, necessitating integrated planning achieve sustainable management ecological
