摘要

Within the context of the circular economy, improving the eco-efficiency (EE) in the management of municipal solid waste (MSW) is of paramount importance. For informed decision-making, understanding the dynamics of EE, i.e., eco-productivity change (EPC) and its drivers—efficiency change, technical change and scale change—have revealed as essential. This study evaluates EPC in MSW management using a parametric approach, enabling the quantification of the influence of environmental variables on performance. An empirical application was developed for a sample of 98 Chilean municipalities from 2015 to 2019. Average EE was 0.796 revealing a good environmental performance of municipalities in managing MSW. Nevertheless, a total of 1,191,841 tons of unsorted waste per year could be recycled if municipalities were eco-efficient. The assessment of EPC identified two sub-periods. From 2015 to 2017, the average EPC was 0.907 indicating a regression in the eco-productivity of 9.3% per year. Between 2017 and 2019 with an average EPC of 1.137, i.e., an improvement of 13.7% per year on eco-productivity. This was due to the positive contribution of eco-technical change and eco-scale efficiency change, whereas EE change remained constant. Moreover, relevant differences in EPC at regional level were found.
