A review of Drying Technologies for Refuse Derived Fuel (RDF) and Possible Implementation for Cement Industry Windi Zamrudy, Sandra Santosa, Arief Budiono, Eko Naryono Department of Chemical Engineering, State Polytechnic of Malang, Indonesia Abstract: Refused-Derived Fuel (RDF) in global energy demand plants has risen over the past decades as a sustainable secondary supply of energy resources. Food waste as a significant fraction of municipal solid waste (MSW) has a great potential for energy production especially in developing country such as Indonesia. To date, many industries focus on drying technologies development for utilization of food waste for energy conversion. Lowering moisture content of food waste is essential to improve RDF heating value (LHV) and further to avoid more steam generation in the combustor. Vaporization of the moisture in fuel consumes a portion of the available energy. The review highlights a number of drying technology application for RDF including direct and indirect steam drying. Furthermore, the review highlights the considerable opportunity for further development of dryer application for Indonesia‟s cement industr y.

The increasing fossil fuels costs promote the cement industry to consider the use of alternative fuels for clinker production. In addition, the energy resources such as coal, oil and other fuels are also affecting to the environment such as greenhouse gasses emission. Its concentration in the atmosphere is rapidly increasing upon combustion of fossil fuel-oil, coal and gas [1]. Environmental regulations and energy costs are the key reasons to replace fossil fuel with renewable energy. In Indonesia, most of cement industry is still generating energy from coal. The problem with power generation from this fuel is their limited availability and the climate damage caused by the emission of fossil- derived CO 2 . As described in [2], the production of 1 ton of cement commonly results in the release of 0.65 – 0.95 tons of CO 2 depending on the efficiency of the process, the fuels used and the specific type of cement product. In this regard, production and utilization of Refuse-Derived Fuels (RDFs) can be an alternative fuels resources. Windi Zamrudy et al /International Journal of ChemTech Research, 2019,12(1): 307-315.
