Performance Evaluation of 3R (Reduce, Reuse, Recycle) Waste Treatment Facilities from a Sustainable Waste Management Perspective: A Case Study in Darmasaba Village, Badung, Bali, Indonesia

Abstract

Community-led waste management encounters challenges in sustainability due to inconsistent amounts of waste produced. Although recognized at the district level, TPS 3R Pudak Mesari in Darmasaba, Bali, does not have a thorough scientific assessment. This research evaluates its effectiveness from the viewpoints of Sustainable Waste Management (SWM) and Circular Economy, and it quantifies the socio-economic-environmental advantages using Social Return on Investment (SROI). A quantitative descriptive-evaluative approach was utilized. The operational performance (X₁) was gauged by combining technical and financial metrics, such as per capita waste generation, density, composition, recovery rates, mass balance, land and labor efficiency, along with Net Present Value (NPV) and Benefit-Cost Ratio (B/C). The socio-economic-environmental effects (X₂) were examined through Likert-scale surveys and incorporated into a comprehensive performance index (Y₁). The SROI analysis (Y₂) looked ahead over ten years, applying a 3. 5% discount rate. The findings show a favorable recovery rate in minimizing landfill waste. Nevertheless, varying waste quantities and insufficient sorting training impose financial strains that obstruct stability. The SROI findings confirm that the social and environmental gains are equal to or surpass costs, highlighting the necessity of financial stability and improved sorting capabilities for the longevity of community-based waste management.
