Abstract: Biomass resources for biogas, also referred to as anaerobic
digestion feedstock or biogas feedstock, include various categories of
organic materials. This chapter highlights the main characteristics of
biogas feedstocks including their suitability, availability, digestibility and
purity. Although the feedstock for biogas can be categorized according
to various criteria, this chapter groups them according to their sectors of
origin (agricultural, industrial, municipal and aquatic), highlighting the
merits and limitations of the most utilized feedstock types within each
category. The basics of feedstock availability, supply and logistics and
their influence on issues related to biogas plant location are also
emphasized.
Key words: biomass for anaerobic digestion (AD), AD feedstock, biogas
feedstock, organic wastes, digestible biomass.

Introduction
Biomass is the general term used to describe all biologically produced matter
and therefore includes all kinds of materials and substances derived from
living organisms. Biomass is widely used for energy purposes and supplies
today some 50 EJ globally, which represents about 10% of the global annual
primary energy consumption (World Energy Council, 2010). According to
the World Energy Council, there is still significant potential to expand
biomass for energy use, including for biogas production, by tapping the
large volumes of unused residues and wastes. Biomass originating from
