Anaerobic digestion is the natural breakdown of organic materials into methane and carbon dioxide gas and fertiliser. This takes place naturally, or in an anaerobic digester.
Biomass is a scientific term that’s used to describe energy derived from plant-derived materials. The primary component of woody materials, plant residues and grasses is called lignocellulose. The structure of the cell wall of lignocellulose is made of long chain sugars which can be turned into biofuels. These long chain sugars are converted to biofuels by introducing acids or enzymes, according to the United States Department of Energy. The definition of biochemical conversion is using living organisms or their products to convert organic material into fuel, according to Mondofacto.com.
