RDF ROLE IN CHANGEABLE SCENARIOS OF MSW MANAGEMENT
The European Unions approach to waste management is based on three principles: prevention, reuse and recycling before final disposal and monitoring. The purpose of this paper is to compare three scenarios for the municipal solid waste (MSW) treatment taking into account the above principles. The considered MSW refers to the case of Romania. This case is interesting as the waste management in Romania is changing quickly as a consequence of its recent entrance into the European Union. For each scenario the mass and energy balance have been developed using a method based on the following concepts: proximate and ultimate analysis of MSW and its fractions; energy efficiency and consumptions for each step; modeling based mass balances. According to the results, the grate system guarantee the highest exploitation of the initial energy content of MSW; in this paper direct combustion is not considered as the initial lower heating value of MSW is so low to be critical for a good combustion; of course a pretreatment before combustion on grate is controversial because the addition of a treatment stage increases the cost of the treatment. In general fluid bed cannot give back the energy necessary for preparing Refuse Derived Fuel (RDF) and this is confirmed also in this paper. The use of RDF in a large thermal power plant as substitute of coal can exploit the higher efficiencies of the electricity conversion; in the study the lower heating value of RDF is anyway critical and alternative solutions must be taken into account for increasing its LHV.
