The direct combustion of biomass resources for energy production can give significant help in building a greener and more sustainable future.
Wood remains the world’s largest source of biomass, but the wide variety of biomass fuel sources also includes:
- Waste from forestry and sawmill operations (bark, wood chips, sawdust, logging debris)
- Urban wood wastes (shipping pallets, packing, and leftover construction wood)
- Agricultural wastes (crop residues, rice husks, nutshells, cotton husk and stalks, olive pomace and pits)
- Fast-growing trees and crops (“energy crops”) such as poplar, willow, and switchgrass, grown especially for energy (electricity or liquid fuels)
- Other natural resources (straw, peat)
- Organic wastes (animal manure, processing wastes)
Biomass energy is carbon neutral: CO2 released during the combustion process equals the CO2 absorbed by plants and trees during their growth. There is no net increase in the atmospheric CO2 if the growth of new plants and trees fully replaces the supply of biomass consumed for energy.
A diverse array of technologies can exploit the energy content of biomasses.
With significant experience in the direct combustion of municipal solid waste, WTE is the technical partner of choice for anyone interested in projects related to biomass direct combustion. Our experience allows us to handle “difficult” fuels facing problems arising from the need to process materials characterized by:
- high levels of moisture, and thus a low energy content (i.e. residues from agro-food, paper, distillery)
- the formation of a high amount of ashes and dust during the combustion process (i.e. rice husk)
- presence of Chlorine or chlorinated compounds (i.e fresh straw)
- presence of Nitrogen or its compounds (i.e.chicken manure)
The experience accumulated designing and realizing waste incineration plants allowed us to develop a design philosophy aiming at the maximization of the flexibility of our systems, the efficiency in energy recovery, the plant availability
