Definitions of terms biomass and bioenergy RS 

Bio-  from the Greek means life

Biomass – general: total amount or weight of living organisms in an area or volume.
Example: plants, animals and birds per hectare of forest / field  or worms, microorganisms and roots in a cubic meter of soil.

Bioenergy is ”energy of life” and must be defined as solar radiation energy transformed during photosynthesis in plants (primary producers according to ecology) using at least 16 chemical elements. The elements H, C, O, N, P, K, Ca, Mg, S, Cl, Fe, B, Mn, Zn, Cu, Mo are considered essential (http://aktionskanemiljo.se/wp-content/uploads/16-essentiella-grund%C3%A4mnen-v%C3%A4xtn%C3%A4ring.pdf) to the growth and development of the plants. In addition to the above-mentioned essential chemical elements are considered several stimulating chemical elements (Co, Cr, Ni, V, Sn, Li, F, Se, Si).
Bioenergy is always bound to above mentioned chemical elements. Most of them are called plant nutrients. Therefore, in each use of bioenergy, we must consider both energy and material flows.
Bioenergy from plant biomass is used as biofuel in food to humans, feed to animals and in the wood to different organisms. Then during the food chains appear bioenergy in residues and in waste that comes from the plant and animal kingdom. By efficiently / smarter exploit bioenergy and plant nutrients throughout society, we can contribute to more solar energy captured in plantations – energy smart cultivation.

Biogas definition – proposal that can be improved by experts (2012)
Biogas definition -proposal RS 2012

Organic – originally from living organisms (plants, animals or microorganisms).

Organic matter – every composite substance containing the element carbon (C) as a main component, it can be solid, liquid or gas and come in three types:
a) renewable organic material – renewed within the time frame 1000 years, including living and more or less actively traded organisms and their organic structures (for example, microorganisms in the litter on the ground or in the stool), but also built up parts of plants and animals (such as paper, wood products, leather and leather products, plastics from starch, and the organisms’ excretions such as urine, feces, ethanol, methane); in Sweden belongs here also peat;
b) synthetic organic material – made of man either renewable or fossil raw materials (eg chemicals, plastics, pharmaceuticals, lubricants, detergents, disinfectants, cosmetics); c) fossil organic material – older than 1000 years (coal, crude oil, natural gas).
