A new assurance system of feedstock logistics and the whole storage system by granulation technology had been established based on regional character,to solve material purchasing and storage of bio-ethanol production in Northern China.The original and new feedstock logistic routes were analyzed on the aspect of feedstock purchasing,storage and transportation by an economic evaluation model.Furthermore,the model then analysed the cost and gain by the effect of expanding production scale.The result showed new feedstock logistics hold a potential benefit of economic cost,shortage and transportation,by greatly simplifying feedstock logistics,which were suitable for large-scale straw fuel ethanol production.
