Abstract

Under the context of China's carbon peak and carbon neutrality, the treatment of municipal solid waste (MSW) is facing new challenge to reduce carbon emission. This study suggests that significant carbon emission reduction and dual cycle of mass and energy can be realized, under the context of MSW classification, by the collaborative treatment of multi-source solid waste in Eco-Industrial Park. Results showed that in 2020, the incineration and landfilling of MSW in China reduced 5.18 million tons of CO2 emission, at the same year, 15 million tons of CO2 emission could have been reduced if the wet waste was treated in Eco-Industrial Park rather than separate treatment. Waste-toenergy (WtE) plant is the core of the Eco-industrial Park, the adoption of larger grate, higher steam parameter, and thermoelectric cogeneration technologies in WtE plant contributes 0.95 million tons of CO2 reduction, annually. It was suggested that multi-source solid wastes should be treated in the Eco-industrial Park to maximize the benefits of carbon emission reduction. At the same time, in response to the national "one belt one road" initiative, the Eco-industrial Park was recommended to be applied in developing counties in Southeast Asia, contributing China's solutions to the carbon emission reduction of global solid waste treatment.
