Abstract

Municipal solid waste (MSW) generation increased significantly each year impacted to the increasingly critical landfill area. This study aims to determine the critical MSW flow in the landfill to be repaired and developed for sustainable waste infrastructure, to design the best scenario tackling the MSW flow into the landfill based on the potential to recycle, recovery materials (compost) and recovery energy/fuel from MSW (RDF/Refuse Derived Fuel). The method is about direct measurement at the landfill for MSW composition according to SNI 19-3964-1994 and physical characteristics; testing the samples in the laboratory for chemical characteristics; empirical calorific value and doing survey to scavengers. Then make modeling scenarios to tackle MSW by using MFA-STAN (Material Flow Analysis-short for Substance Flow Analysis) integrative method for each year over a period of five years. MSW critical flow in the landfill to be repaired and developed for sustainable MSW infrastructure contained in the composition of organics (65,75%) and plastics (11,937%). Based on laboratory tests and surveys, waste processing technology potentially applicated by composting (58,906%), recycling (25,417%) and RDF (27,619%). Scenario 3 is appropriate scenario to reduce MSW to be dumped (about more than 50%) also to increase the lifespan of serviceability landfill.
