Abstract(s)
Municipal Solid Wastes (MSW) that contain mixtures of paper, wood, green wastes, food
wastes, plastics, leather, and rubber can have energy characteristics similar to wood. Use of MSW
as a fuel can be accomplished by burning the as-received material, called mass burning, but
processing is often required before it can be burned effectively. The purpose is to reduce size and
remove materials, valuable materials or non-combustible materials in order to be reclaimed and
used as alternative fuel for sustainable disposal and converted into green and clean energy.
The impact of burning these heterogeneous materials in traditional boiling systems, as primary or
supplemental fuel, needs to be assessed: the physical and chemical characterization of raw
materials should be performed. According to Portuguese Standard NP 4486:2008, a classification
system is used based on Refuse Derived Fuel (RDF) main parameters: lower heating value,
chlorine and mercury content.
Higher heating value is in fact associated with paper/card, plastics, wood and textiles content
and, once these materials have in their composition biogenic compounds (40-80% w/w), they
become an interesting alternative fuel to accomplish the reduction of CO2 emissions.
