Research progress on anaerobic digestion of fruit and vegetable wastes

With the rapid development of agricultural intensive cultivation, the production of agricultural wastes has increased dramatically. Fruit and vegetable wastes including waste of navel orange, as a good biomass energy feedstock, have a certain potential of anaerobic digestion for energy production. This paper reviewed and compared the treatment technique of fruit and vegetable wastes. It was concluded that co-digestion of of waste navel orange with high-nitrogen content wastes by using continuous one-stage systems was a promising alternative.
