Abstract

The importance of waste energy is increasing with increasing emphasis on carbon neutrality. Solid recovered fuels (SRFs) are manufactured to recycle waste into fuel form and can replace fossil fuels by recovering the heat generated by using them. This study calculated the manufacturing and energy recovery efficiency of SRF facilities. The manufacturing efficiency was calculated as the amount of SRFs manufactured compared to the amount of input waste. The energy recovery efficiency was calculated using the R1 method, which is applied to incineration heat energy recovery facilities. The manufacturing efficiency was 69.5%, which varies depending on the combustible material content of input waste. The energy recovery efficiency was 85.4%, which satisfied Korean energy recovery efficiency facility standards. Our study highlights the manufacturing and use of SRFs as one of the options for recycling waste and its potential as a substitute for fossil fuels.
