Abstract

Aim: This study evaluated air quality, worker exposure, and health risks at a 3R Integrated Waste Processing Facility in Banyumas Regency, Indonesia, where waste is combusted for extended periods. Methodology and results: Over five consecutive days, concentrations of PM2.5, PM10, CO2, CO, and respirable dust were measured during morning and afternoon shifts. Results revealed persistently hazardous particulate matter levels: PM2.5 exceeded World Health Organization (WHO) limits by 10–90 times, and PM10 by 5–44 times, with no significant difference between sampling periods (p > 0.05). Respirable dust and CO remained within safe thresholds, while CO2 was consistently elevated during morning startup operations. Risk Quotient (RQ) analysis identified CO2 as the only pollutant above the safety threshold (RQ = 1.184), correlating with worker-reported symptoms such as dizziness, fatigue, and difficulty concentrating. Intake calculations confirmed high chronic health risks, particularly for respiratory and cardiovascular disease. Conclusion, Significance, and Impact: Immediate interventions are required, including improved combustion efficiency, local exhaust ventilation, strict use of personal protective equipment, and regular worker health monitoring. Long-term strategies should focus on regulatory reform, advanced emission control technologies, and transitioning toward sustainable waste management through recycling, composting, and circular economy practices. These actions align with United Nations Sustainable Development Goals for health, sustainable cities, and climate action.

Abstract

Aim: Waste sorting at-source is vital for sustainable waste management and the circular economy in Indonesia. Despite regulations, community programs, and digital interventions, sorting remains limited. This study explores self-reported sorting behaviors among urban residents and examines how waste banks may enhance participation. Methodology and results: We surveyed 220 respondents from Indonesian major cities and applied Two-Step Cluster Analysis and chi-square tests to assess links between sorting behavior, socio-demographics, and waste bank participation. The main barriers were lack of space and time. The 57 respondents with access to a waste bank, only 14 were members; 43 were uninterested, often citing inconvenience. Active members were positive about the possibility of automation technologies, including automated sorting and collection, weighing machines for pricing, and digital payments. Many also suggested a mobile app to track deposits. Conclusions, Significance, and Impact: Technological innovations paired with incentives potentially reduce participation barriers. Integrating digital and automated solutions with behavioral insights may help overcome current limitations and foster a more effective circular economy in Indonesia.
