摘要：Hazardous Waste such Oil Sludge combined with biomass (coconut shell and rice husk) was utilized as an alternative fuel in cement plant in form of Densified-Refused Derived Fuel (D-RDF).D-RDF were Co-Processed with primary fuel into Rotary Kiln in order to reduce usage of fossil fuel and eliminate the hazardous waste by thermal treatment,meanwhile to recover the energy contained in the D-RDF,the utilization of these waste are expected without causing adverse effect into the environment.Co-Processing of D-RDF as alternative fuels into cement plant kiln must follow the regulation applied in Indonesian Environment and Forestry Minister regulation 19/2017 and European Union for Responsible Incineration and Treatment of Special Waste (EURITS).Based on previous research,D-RDF composition of oil sludge and biomass at 1:1 ratio with 5% starch addition was choose as they give best calorific value at 6000 kcal/kg.The objectives of this research are to observe the emission caused by the utilization of these D-RDF and potential effect into cement or clinker product.The result show NOx and CO value are meet the standard requirement by government regulation meanwhile SO2 value which are 1251 mg/Nm3 and 1500 mg/Nm3,over the regulation standard which is 650 mg/Nm3.This issue could be overcome in the plant with pretreatment of D-RDF and utilization of Bag House Filter or Electrostatic Precipitator before release the emission to the stack.Trace element analysis of D-RDF ashes (As,Cd,Co,Cr,Cu,Hg,Mn,Ni,Pb,Se,Sn dan Zn) show the result are meet the EURITS regulation,which mean utilization of D-RDF will not give quality defect to cement or clinker product.
