Life cycle assessment (LCA) kegiatan bank sampah di pedesaan (Bank Sampah Asoka Berseri, Desa Sokosari, Tuban)
Abstract
Life Cycle Assessment (LCA) is a method that can be used to evaluate the waste management system based on the potential impact produced. The Asoka Berseri Waste Bank in Tuban Regency is an example of a waste processing unit that aims to reduce the possible effects of waste generation both in quality and quantity in rural areas. This study aimed to calculate and evaluate the potential environmental impacts from the waste bank, then compared it with conventional waste management carried out by the community. The method used was based on CML Baseline v4.4 and ISO 14000 standards, including goal and scope, life cycle inventory (LCI), life cycle impact assessment (LCIA) and interpretation. The LCA simulation was carried out with the OpenLCA software to calculate the value of the potential impact of each kilogram of waste produced. Based on the simulation results, every 1 kg of waste managed by the waste bank produced a lower potential global warming impact (6.395 kg CO2 eq.) than open dumping (13.057 kg CO2 eq.) and open burning (10.850 kg CO2 eq.). Further processing of solid waste into RDF and compost at the Waste Bank present a lower potential environmental impact and increase community income.
