Bioenergy

Abstract

Bioenergy is obtained from biomass. The term biomass encompasses all materials of biological (organic) origin, i. e. plants as well as animals and the resulting residues, byproducts and waste products (e. g. excrement, straw, sewage sludge). In chemical terms, biomass consists of carbon (C), oxygen (O) and hydrogen (H) plus various macro and microelements (such as nitrogen, potassium, chlorine). © 2009 Springer Berlin Heidelberg.
