The Potential of Solid Waste and Greenhouse Gasses Reduction in Tambak Osowilangon Material Recovery Facility in Indonesia During the Covid-19 Pandemic

Solid waste generation can increase due to people's activities that compared the early pandemic in 2020. The solid management paradigm is no longer focused on landfilling landfills. reduction extend landfill's lifetime, one of activity facilities Material Recovery Facilities (MRF). Surabaya, capital city East Java Province Indonesia, has several MRF. One them Tambak Osowilangon . This study aims determine ponds Facility during COVID-19 and predict greenhouse gas based waste. triangular method calculates gases (GHG) prediction MRF was produced at 2704.946 kg/day. highest composition achieved by food (63%), existing Ponds 56.08%. total volume GHG without scenario 6.16 x 10 6 m 3 /year, while from an Tambakosowilangon 2.4 3/ year. reduce 61.04%
