Biofuel Production Byproducts as Soil Amendments

摘要: Attempts to reduce reliance on fossil fuel as the sole source of energy has resulted in production from different organic materials. Due increasing demand worldwide, renewable sources been growing rapidly, and it was estimated 2002 contribute 14% world’s supply. Several technologies such biochemical, fermentation, thermo-chemical, gasification pyrolysis, chemical extraction, transesterification processes have employed convert materials energy. These ­produce not only energy, but also valuable byproducts which include distillers grain, thin stillage, glycerol, ash biochar. bioenergy industry, there will be an abundance being generated. Recently, some these are disposed by incineration, e.g. or landfilling, ash. This disposal may adverse effects environment. Therefore, a proper method, can economically sound environmentally safe, needs sought. As contain carbon plant nutrients that potentially soils crops, consideration potential uses must their application soil. Carbon other essential added soil recycled. If fed animals, case grain stillage byproducts, manure is produced containing higher content nutrient compared animals regular grain. type hurt environment if properly managed. The for recycling soil-plant system through direct indirect ­byproducts widely ­covered literature. review covers relevant information use amendments fertilizers agricultural lands, considers opportunities future applications.
