Co-pelletization of pine sawdust and refused derived fuel (RDF) to high-quality waste-derived pellets

Energy generation from non-hazardous waste streams, which are unfeasible to be reused or recycled, can help overcome some of the problems related fossil fuel depletion, global increase in energy demand and management under restricted landfilling. One main drawbacks waste-to-energy strategies is poor combustion properties waste, densification could circumvent. This work studies co-pelletization refused derived (RDF) pine sawdust (PIN) a continuous pilot pellet mill that resembles industrial pelletization. The effect RDF contents up 90 wt% on set parameters has been assessed: pelletization consumption, physical (durability, particle bulk densities), net calorific value density obtained pellets. In addition, slagging, fouling corrosion, phenomena associated with combustion, were estimated ash composition. Results showed obtaining pellets low loading (2–9 wt%) was feasible. They accomplished ISO 17225-2 solid biofuels standard for use, presented deposition corrosion risks. On other hand, 30–90 also manufactured complied UNE-EN 15359:2012 recovered-fuel recovery incineration co-incineration plants. All produced durability above 96.9% 10.7 MJ/kg, respectively. higher than 10.6 GJ/m3 formulations content 50 wt%. It demonstrated blends PIN provide high-quality high load material, same operational conditions required versatile process tailored different product requirements depending end-use. promotes generates out fraction no relevant adding economic environmental benefits.
