The Implementation of Waste Reduction in Supit Urang Malang

Abstract

This paper aims to determine the effect of waste management on the implementation of waste reduction in the Supit Urang landfill. This study uses weighbridge and quartering methods to determine waste generation and composition. The study is conducted at the sorting and composting facilities in the Supit Urang Landfill under the Emision Reduction in City-Solid Waste Management (ERiC-SWM) program, each facilities having a capacity of 35.000 kg/day for the sorting facility and 15.000 kg/day for the composting facility. The waste reduction at Supit Urang Landfill through the ERiC-SWM program is still relatively low, with a total waste reduction of 1.561,78 kg/day or 2,54 %. The composition of the reduced waste consists of three types of waste at the sorting facility: paper waste at 6,29%, plastic waste at 38,95%, and metal waste at 0,64%. Meanwhile, at the composting facility, only organic waste is reduced, accounting for 10,56 %.
