Sažetak
Prices of crude oil and petroleum products have reached a level at which we have to start thinking about alternative sources of energy, which can be organic and biological waste, like cow dung, hay, straw, corn and as such represents a high grade raw material to obtain alternative forms of energy such as biogas, biodiesel and ethanol. With mutual synergy of biogas, biodiesel and ethanol production occurs a closed circuit, regard to waste disposal and exploitation of raw materials. The plant is designed to meet all environmental requirements, all requirements of fire protection, and all the requirements of explosion protection. With such a production of biofuels the amount of waste and emission of harmful gases are reduced and all by-products are exploited within the plant. Input charges for biogas production are cow manure and hay, corn, for the production of ethanol, rapeseed oil and waste cooking oils for production of biodiesel. Obtained plant by-products like technical glycerine, corn silage and waste waters, are used further for biogas production. Moreover, glycerol can be placed on the market, corn silage can be processed and sold as animal feed, sewage sludge from the anaerobic reactor can be used as fertilizer. Most important of all is to exploit biological waste for energy obtaining instead of being inadequately disposed in the environment, which is frequently done so far. A biogas plant is designed for a capacity to produce 2.2 MWh of total energy. In anaerobic bioreactor is produced 8600 Nm3/day of biogas, from which is obtained 0.8-1 MWh of electricity energy and 1.2-0.8 MWh (3600 MJ-2880 MJ) of thernal energy.
