Energy Generation

Energy from waste offers recovery of energy by conversion of non-recyclable materials through various processes including thermal and non-thermal technologies. Energy that is produced in the form of electricity, heat or fuel using combustion, pyrolization, gasification or anaerobic digestion is clean and renewable energy, with reduced carbon emissions and minimal environmental impact than any other form of energy.

RDF (Refuse Derived Fuel)

Municipal governments throughout the world are facing choices about how to manage the unending stream of waste generated by their residents and businesses. In some places landfills and dumpsites are filling up, and all landfills and dumpsites leak into the environment. As populations continue to grow, the issue of waste becomes more urgent and more complicated.

RDF production line consists of several unit operations in series in order to separate unwanted components and condition the combustible matter to obtain the required characteristics. The main unit operations are screening, shredding, size reduction, classification, separation either metal, glass or wet organic materials, drying and densification.

Indicative net Calorific value of RDF vs Coal

Both fuels were co-combusted with coal in a 50 kW fluidized bed combustor and the metal emissions were compared. Synthetic SRF was prepared in the laboratory by grinding major constituents of MSW such as paper, plastic, textile and wood. RDF was obtained from a local mechanical treatment plant. Heavy metal emissions in flue gas and ash samples from the (coal+10% SRF) fuel mixture were found to be within the acceptable range and were generally lower than that obtained for coal+10% RDF fuel mixture.
