Analysis on Social Effect for Three Models of the Straw Power Plant Supply Chain

Crop straw power plant is environmental-friendly, but crop straw has low density, so the efficiency of the collection and transportation is very low, and per unit of weight crop straw reutilization will more expensive and make more pollution. In this paper, based on ABC (Activity Based Costing) and LCA (Life Cycle Assessment), the data of economic and environmental performance in the crop straw power plant supply chain are analyzed through quantitative calculation of cost and pollution of per unit weight. We find compression ratio in the pretreatment is key factor. Compression ratio is higher, economic and environmental performance is better, but it needs more investment. With straw supply uncertainty, compression ratio in straw supply chain needs balance.
