Estimating methane emission from solid waste landfill using various different methods

Solid waste management is one of biggest problems for big cities in Indonesia. Currently, open dumping method is applied for managing the waste generated and produces methane emission as one of potential global warming gasses. This paper examined the methane that generated by Benowo landfill in Surabaya and Antang landfill in Makassar. Four methods were applied, namely IPCC default method, zero order, landGEM, and Order decay method. The result showed that methane emission quantity generated by these two landfills was significantly influenced by two local climate parameters: temperature and rainfall intensity. In addition, the analysis method used was also contributing to the volume of methane emission emitted.
