Improvement of recycling-based municipal solid waste management in Padang City, West Sumatera, INDONESIA

Abstract

Municipal solid waste (MSW) characteristics including generation rates, composition, proximate analysis, and recycling potential were evaluated for suggesting the appropriate recycling-based municipal solid waste management (MSWM) in Padang City. Indonesian National Standard (SNI) 19-3964-1994 was used as guidance for obtaining MSW characteristic through 8 consecutive days sampling in 2016. MSW characteristics from domestic and commercial areas were compared and evaluated to find the most suitable recycling-based MSWM for each area. As a result, both areas show MSW differently in composition. Domestic area generates higher food and yard waste compared to commercial area. On the contrary, commercial area generates higher amount of dry waste. Recycling potential data shows that domestic area generates biodegradable waste (59.420 % weight) higher than that of commercial area (21.816 % weight), while commercial area generates marketable waste (47.949 % weight) higher than that of domestic area (5.730 % weight). Aerobic or anaerobic treatment facility must be implemented for domestic area, while sorting, collecting, sell and recycling activities of marketable dry waste must be carried out more intensive for commercial area. Such treatments and activities must be incorporated into 3R waste treatment facility/TPS 3R, integrated waste treatment facility/TPST, and waste bank (WB).
