University in collaboration with company Wongphanit Korat Top Secret Co., Ltd. has taken old mattresses that have deteriorated. of student dormitories to be transformed and turned into 14.14 tons of waste fuel (RDF) to enter the electrical power production process. It has been improved and converted into solid fuel that has properties. In terms of heating value, low humidity, suitable size and density for transport or incineration, and consistent chemical and physical composition.

General characteristics of waste fuel are odorless. Removing germs from heat treatment Reduce the risk of exposure to germs It is the right size for feeding into the furnace-boiler. and is denser than general waste and biomass, approximately 450-600 kg/m3, suitable for storage and transportation. and has a high heat value equivalent to biomass, approximately 13-18 MJ/kg, and has a low moisture content, approximately 5-10 percent.
