Research Progress of Food Waste Biodegradation Technology
Food waste accounts for an increasing proportion of municipal solid waste,and its composition is very suitable for microbial growth.Improper disposal of food waste can lead to rot and environmental pollution.At present,there are various technologies for resource treatment of food waste,each with its advantages and disadvantages.This paper presents an overview of the principle of food waste biodegradation and compares it with aerobic composting and bio-drying,both of which are aerobic treatment methods,to demonstrate that biodegradation offers better reduction advantages and is more suitable for front-end treatment of food waste.The enhanced strategy for biodegradation of food waste is presented from three perspectives:microbial agents for degradation,pretreatment of food waste,and the selection and compounding of fillers.Additionally,some of the large-scale applications of biodegradation technology are outlined to serve as references for further enhancing biodegradation efficiency.
