In agriculture, for example, there are huge amounts of waste worldwide, such as coconut shells, green waste, grasses and other biowaste. Previous waste is now used to produce biogas via the process using gasification or oxidizing agents. The biogas, in turn, is used for the production of electrical energy or, for example, for cooking.
The further utilization of waste and residual materials is therefore important, otherwise unused quantities of biological waste material rotting itself and in turn emissions are triggered by fermentation and digestion processes.
