RDF : Refuse Derived Fuel

Municipal solid waste (MSW) management is a serious challenge if the waste is simply collected and dumped or even if it is buried in a landfill. In order to meet these challenges, refuse-derived fuel is one of the best options. RDF is obtained from municipal wastes and used as an alternative fuel. In so doing, a city can both reduce its solid waste and utilize the fuel in place of less environmentally friendly options such as coal and oil. In addition, in Korea the introduction of RDF facilities is expected to save the equivalent of 25.1 billion KRW in oil imports.

Purpose

By utilizing RDF not only has the issue of Korea’s lack of conventional resources been addressed, and a reduction in greenhouse gas emissions achieved but also the problem of the disposal of hazardous wastes can be dealt with. For Daesung Group there is an additional benefit in that this project creates a green energy business synergy with Daesung’s landfill gas-to-energy and CES projects. Further, Daesung’s technical prowess in renewable energy and environment is verified for export overseas.

Explanation

Solid waste management involves the collection of waste mainly generated by human beings in an urban setting. It consists of household, industrial, agricultural and bio-medical waste. In turn, these wastes can be broken down into biodegradable waste, recyclable waste, inert waste, electrical and electronic waste, composite waste, harzardous waste and toxic waste. RDF consists largely of combustible component of municipal waste such as plastics and biodegradable waste. RDF is an excellent choice for Korea because the country almost completely lacks its own energy resources and because RDF successfully tackles the issues of air and environmental pollution. Further, because the cost of operating a RDF plant is less than the cost of incinerating trash and the waste is treated utilizing environmentally-friendly processes, there are far fewer concerns about NIMBY (not in my backyard) issues from local residents.
