High caloric waste out of various types of biomass like fresh wood, straw, etc.
Pellets out of waste/rejects
The high caloric pellets are produced out of reject of the paper industry or of a high caloric waste steam after the treatment of MSW. These pellets replace coal in the production of energy.
Sawdust and chips from the sawmill, or chips produced out of energy logs, are dried crushed in mills and pressed into an industrial or DIN pellet. The industrial pellets will replace coal in a classical coal fired power station. The DIN pellets go to the retail industry.
After drying the wood chips, the chips are roasted in an airless atmosphere. The fix carbon content of the wood will increase together with the caloric value. The transportation cost of the roasted wood is reduced due to the pelletisation. These dense black pellets replace coal in a coal-fired power station.
Contaminated soil (with mercury, TNT, oil, chemicals) and asphalt, containing with tar, are cleaned on high temperature during a gasification process. Syngas will be burned and the heat is re-used in the process. Flue gas is cleaned in an extensive gas treatment system.
Medical waste, delivered in plastic boxes, is gasified on high temperature to destroy and to transfer the solid waste into a syngas that is burned. The produced energy (steam) is re-used to dry sludge or to produce electricity. Flue gas passes several wet gas cleaning steps before the clean gas leaves the installation.
