Solid fuel from physical residues of nuts
The seed of physical nuts contains the oil around 25-35% of the total unit weight. This form of waste has a crude oil content of 75-65%. Waste can be transformed into solid fuel through a densification process. The carbonization or non-carbonization process can also be applied to improve the quality of these solid fuels.
In the carbonization process, waste is fed into the reactor to remove moisture, volatiles, and tar. After this process, they are sent to the densification process. This process forms the material into briquettes using a press machine.
Two types of press machines are used, hydraulic and screw. The densification product is densified material called briquettes. This fuel can be used as a solid fuel. The briquettes can easily be burned in the conventional oven or stove. In commercial production, the briquettes are used to burn water in the boiler. The generated steam is sent to a steam turbine. This steam turns the wheel of the generator to produce electricity.
Gas fuel from physical nut waste
Gaseous fuels can be produced through an anaerobic digestion process. This process is a chemical process that involves microorganisms without the presence of oxygen in a digester. This process produces methane, carbon dioxide, hydrogen, nitrogen, hydrogen sulfide, and a small amount of gas. Methane is the largest composition compared to other gas products. This process can be classified into two types: dry and wet anaerobic digestion. The differences between these anaerobic processes are the proportion of biomass and water used in the digester.
