| Abstract: | A single municipal solid waste treatment technique may not be adequate to effectively treat the municipal solid waste (MSW) produced across the globe. This is due to the different composition and physical characteristics of the MSW. This has changed China's waste management strategy to integrated waste management systems since the 13th Five-Year-Plan in 2016. Therefore, the present study evaluates the electricity generation potential, economic feasibility, and the environmental impact of integrated waste-to-energy technologies in China, taking the Beijing-Tianjin-Hebei region as a case study. The study considers the integration of anaerobic digestion and landfill gas to energy (AD/LFGTE), anaerobic digestion and incineration (AD/INC), and incineration and landfill gas to energy (INC/LFGTE). The prominent findings show that AD/LFGTE has the highest electricity generation potential during the project period. It was found that AD/LFGTE contributed 24.52% to the region's electricity needs, while AD/INC and INC/LFGTE contributed 22.68% and 1.88%, respectively. According to the economic analysis, all the projects are viable in the area and have a positive net present value. The AD/LFGTE project was found to be more economical with a lower levelized cost of energy (US$0.0915/kWh), shorter investment payback period (9.1 years), and higher profit (US$1,331.19 million) on investment. It was observed that the integrated systems could avoid a considerable amount of coal consumption and greenhouse gas emissions, with AD/LFGTE having the highest saving ability.
