Straw is a common agricultural waste; its quantity is huge. In 2018, China produced 110 million tons of waste straw. The traditional way for farmers to treat straw is to burn it. However, burning straw will cause serious air pollution. At the same time, straw can be used to produce biogas via anaerobic fermentation, which is a clean and renewable energy source. Therefore, the research on anaerobic fermentation of straw is widely concerned. Straw is difficult to ferment directly because of its composite structure of lignin and cellulose. Therefore, straw needs to be pretreated. This review summarizes the previous research results in recent years on main straw pretreatment methods and factors affecting the efficiency of anaerobic fermentation of straw. In addition, the solutions to the problems existing in anaerobic fermentation of straw were put forward. This review could provide guidance for the follow-up research on anaerobic fermentation of straw.
