Abstract
One important factor affecting functioning of a sugar factory is minimizing the costs of its operation. Wastewater treatment produces biogas, use of biogas can reduce the expenses of a sugar factory. The aim of the published paper is to present results concerning the possible use of wastewater treatment for biogas production and its subsequent further use in sugar technology. Assessment of the work of the biological wastewater treatment plant and its biogas production confirmed the necessity of WWTP on the premises of the sugar factory. Wastewater treatment plant produces biogas, which covers the significant energy demands in a sugar factory, reducing consumption of natural gas. Based on assesment of the results, it is recommended to increase the wastewater treatment plant capacity and consequently increase the production of biogas as an important factor of self-sufficiency of a sugar factory.
