A hybrid waste–solar power generation and waste disposal system in Luang Prabang, Lao People's Democratic Republic (Lao PDR)

Abstract

This research presents a hybrid waste–solar power generation and waste disposal system in Luang Prabang, Lao. A waste management problem of 19,546.52 Ton in 2021 is the focus of waste-to-energy (WtE) technology. A 230-kg/h steam sterilization method is used to autoclave hazardous waste combined with a 40-kW drying room to produce type 3 refuse-derived fuel (RDF-3). The hybrid system generates 221.03 kWe of power at a system efficiency of 6.67%. A levelized electricity cost (LEC) of 0.29 USD/kWh and a carbon dioxide emission of 0.156 kg CO2/kWh are achieved to address economic and environmental impacts.
