Food waste, a putrescible form of waste, comprised of 30% of the total municipal solid waste stream in DaejeonMetropolitan City (DMC) in 2012. Proper management of food waste is a challenging task for local government. Thisstudy was conducted to determine material flows when treated food waste in various recycling facilities. Material flowsin the recycling processes were collected by site surveys, field trips and discussion with operators and governmentalemployees. Material flow analysis (MFA) was conducted to quantify the flow of food waste from generation to disposalfor the year 2012. MFA along with its mass transfer coefficients were determined based on the inputs, outputs and wastefluxes. According to the mass transfer coefficient results, treatment efficiency for the dry and wet feed manufacturingfacility was found to be higher than other treatment facilities. Water consumption was higher for the composting site,resulting in large volume of wastewater (mass transfer coefficient 1.539). While large amounts of screening materials suchas plastic, chopsticks, aluminum foils, and bottle caps were generated at the composting site, mass transfer coefficients(0.312) at the dry and wet feed facility were relatively high, implying effective treatment of food waste occurring. Theresults of this study help to facilitate waste management policy decision-makers in developing effective food wastemanagement techniques in DMC.
