Extraction of dormant energy from biomass is a
complex process. There are three stages of
converting organic matter into heat or
electricity: obtaining the biomass from the
environment, biomass processing - in this
particular case it is pellet production, thermal
treatment - usually burning.
The first phase in the production process is
preparation of raw materials. The diversity of
materials that can be used in this process was
mentioned earlier. Biomass can therefore be
obtained directly from the environment, may be
a waste in the production of other goods or can
be harvested from dedicated plantations.
Scheme 1 gives an overview of the preparation
of material for further processing.
