Environmental damage cost assessment from municipal solid waste treatment based on LIME3 model.

[Display omitted] • Environmental damage cost of municipal solid waste (MSW) treatment was assessed. • LIME3 model was used to evaluate four types of endpoint environmental damage cost. • Landfill dominated social asset cost, and incineration dominated human health cost. • The priority of MSW treatment was landfill < incineration < compost < fermentation. • 1/3 of damage cost for Shanghai was reduced after implementing MSW classification. Environmental damage cost can measure the impact of pollution caused by human activity on final safeguard subjects from endpoint perspective. Application of environmental damage cost to municipal solid waste (MSW) management is still rare. To fill such a research gap, this study established a MSW environmental damage cost assessment method using Life Cycle Impact Assessment Method based on Endpoint (LIME) model. Four types of environmental damage cost, namely, primary productivity, social assets, biodiversity and human health for waste treatment were investigated in the city of Shanghai. Results show that the environmental damage cost was 113.7, 116.9, 140.0, 144.0 and 170.8 million dollars in Shanghai from 2014 to 2018, respectively. Damage cost of social assets was the dominant component, accounting for about 55%. Landfill mainly caused social assets damage cost, while incineration mainly caused human health damage cost. Scenarios analysis further revealed that after implementing MSW separation, the total environmental damage cost could be reduced by about 1/3. The best MSW treatment method is fermentation, followed by compost, incineration and landfill, with unit environmental damage cost being 0.22, 4.51, 16.04 and 23.47 USD/ton, respectively.
