Abstract: Livestock and poultry manure and crop straw are important agricultural waste resources.Biogas production based on agricultural waste is most important use of current agricultural waste.A field survey and comparative analysis of Jindongtai model and Mazhuang model was conducted.Results showed that Jindongtai model mainly used livestock and poultry manure for biogas production，and its economic，social and environmental benefits were significant.However，this model had high requirements for capital，technology and geographic location and was limited in promotion.Social and environmental benefits of Mazhuang model were significant，but economic benefits were poor.Under dual background of promoting rural centralized living and rural waste disposal，Mazhuang model had strong promotion potential.Results of this paper could provide valuable reference for development of other large and medium-sized biogas projects in northern Jiangsu and surrounding areas.
