In many agricultural processes there are residues which may be used as a source of energy.
Typical of these processes is the high fiber waste from milling grain, cake from the extraction of oil from olives and rape seed etc., saw dust and wood waste from saw mills and highly inflammable dust from the cork industry.
Using these residues avoids the cost of waste treatment and the risk of pollution.
By exploiting these energy sources, thermal energy can be generated which can be used in the production process with any surplus used for the generation of electricity. Not least, their re-use contributes considerably to the reduction of pollution and the protection of the environment.
