PREDICTION OF GREENHOUSE GASSES EMISSION FROM MUNICIPAL SOLID WASTE SECTOR IN KENDARI CITY, INDONESIA (Prediksi Emisi Gas Rumah Kaca dari Sektor Sampah di Kota Kendari, Indonesia)

Abstract

Municipal solid waste sector is considered as one of major contributors for Greenhouse Gasses (GHGs). GHGs that are CO 2 , CH 4 and N 2 O were emitted from any waste management stages including waste transportation, treatment and disposal. The paper aims to predict GHGs emission from the last two stages above using the guidelines issued by Intergovernmental Panel on Climate Change (IPCC) year of 2006. By comparing amount of waste generation at source and waste comes to landfill site, it can be found that the municipality only transport 68% of total 174 ton/day waste generated throughout the city. Percentage of waste to be composted and openly burned were 3.25 and 0.06 % of total waste generated, respectively. Organic waste, plastics and paper were dominantly found at final disposal site by 41, 31 and 9 %, respectively. GHGs emission from landfilling becomes a major source and it equals to 50,010 ton CO 2 equivalent/year. The second largest of GHGs generator is waste burning equals to 340 ton CO 2 equivalent/year. While waste composting generates 10 ton CO 2 equivalent/year. Amount of GHGs emission can be reduced by reducing amount of waste to be landfilled and improving better practice at final disposal. Further, any measures regarding with Reduce, Reuse and Recycling (3R) of waste becomes important to be improved to reduce GHGs emission. Abstrak Sektor sampah merupakan salahsatu penyumbang utama Gas Rumah Kaca (GRK). GRK meliputi CO 2 , CH 4 and N 2 O diemisikan dari berbagai tahapan pengelolaan sampah, termasuk pengangkutan, pengolahan dan penimbunan sampah.
