Climate Change Mitigation By Municipal Solid Waste Syngas Substitution for Chemical Feedstock

The various waste treatment technologies are being developed to recover the useful energy and reduce greenhouse gas emission simultaneously. Most of them are to produce thermal energy or electricity by combustion or gasification process. In this study, the reduction effect of CO2 emission to atmosphere has been examined by substituting chemical feedstock to municipal solid waste syngas. Currently, the chemical feedstock is produced by thermal cracking the fossil fuel. Part of carbon in solid waste will be buried in final chemical product such as plastic, otherwise these carbon would be emitted as CO2 during combustion or CH4 from anaerobic digestion in landfill site to make global warming effect. The major data of pilot gasification plant are used, and the leakage emission is included. Insight from the study, the solid waste syngas substitution for the chemical feedstock can be considered as one of the climate change mitigation method in chemical industry.
