Study of the substitution of fossil fuels by RDF produced from municipal solid waste of Hanoi: A case study

Abstract

Looking for the possibility of using Refused Derived Fuels (RDF) in the substitution of fossil fuels is one of the main subjects in the Waste to Energy aspect. Therefore this study has been taken in this direction. The influence of waste composition on RDF quality produced by Dry Stabilization Process (DSP) and the evaluation of CO2 emission of this product were undertaken. Input material for RDF with different percentage of paper, textile, nylon bag and bio-waste were taken from municipal solid waste of a district in Hanoi. The influence of this input on RDF quality resulted from 3 test samples (R1, R2 and R3). During the composting step stabilization time, temperature, leachate volume and the water content were noticed. As a result, heating value of dry sample and wet waste was determined. Gross heating value of this produced RDF was compared with it of fossil fuel and RDF from other studies. Thereafter, total Green House Gases (GHGs) estimation from both pre-treatment of RDF and RDF utilization steps were calculated.
