Waste biomass categories

A major activity at Maasvlakte Power Plant is the co>combu tion of biomass pellets that are produced from sewage sludge, waste wood (untreated wood) and paper sludge of the biomass plant in the direct vicinity of the power plant site. The biomass pellets are transported by conveyor bells to the power plant and are blended with the raw coal in the raw coal bunkers. In the new Environmental Impact Study many other "fuels" were also considered. The fuels can be subdivided into three categories ... 

Several approaches have been proposed for the production of liquid fuels from biomass. Alcohol production via fermentation is state-of-the-art technology for specific feedstocks (grain etc.). The use of non-food sources (urban refuse, industrial wastes, etc.) is not fully developed. Processing times are on the order of days however for biological conversion. Non-biological methods fall into two categories (1) direct liquefaction, and (2) indirect liquefaction. Both involve a thermal conversion step. Direct liquefaction... 

Bioadsorption can be described as the removal of substances from solution by biomass materials. The biomass materials that have been investigated in bioadsorption studies come under the following categories bacteria, fungi, algae, yeast, waste materials of the food and agricultural industry, lichens and other polysaccharides.
