[Evaluation and Analysis of Carbon Reduction Effect of Domestic Waste Incineration Power Generation].

Abstract

The annual average carbon dioxide emissions were evaluated from a large-scale domestic waste incineration power generation project in Beijing using the Chinese Certified Emission Reduction （CCER） method. Compared with landfill methods without landfill gas recovery, the carbon reduction effect of this project was quantitatively assessed. The results showed that the baseline carbon emission （calculated by CO₂-eq, the same below） per unit of waste was 1.041 t·t^-1. The carbon emission of waste incineration power generation unit waste was 0.457 t·t^-1. The contribution of leakage emission was relatively low and the carbon emission per unit of waste was nearly zero. The main source of carbon emission came from waste incineration with carbon emission per unit of waste being 0.456 t·t^-1, accounting for 99.89% of the total waste incineration emission. The annual carbon emission reduction for the project, which incinerated 1.83 million t of waste per year, was 1.063 5 million t, with a carbon emission reduction per unit of waste of 0.581 t·t^-1. The results of this case study were important for establishing the carbon emission baseline in Beijing's waste management industry and achieving the goals of carbon peak and carbon neutrality in China. It serves as a crucial theoretical foundation for the development of comprehensive and refined carbon accounting standards and policy frameworks in the solid waste management sector.
