The project was carried out for the company Doral EI Gazeko sp. z o.o. and involved the comprehensive implementation of an investment task to build a 0.999 MW agricultural biogas CHP plant in the village of Kaplonosy, Wyryki municipality. A common vision related to RES, combined with the experience and qualified staff of MDI ENERGIA S.A., made it possible to create an agricultural biogas plant for the production of biogas. The investment task consisted of preparing the project, documentation and permits necessary to build the biogas plant. The scope of work included the completion of the complete technical infrastructure, road infrastructure, electrical connections, etc. Thanks to the biogas plant in Kaplonosy, the production of energy in an ecological and safe manner reduces environmental pollution. It should be emphasised that each biogas plant contributes to the use of bio-waste from the agricultural and food sectors and supports local production and processing facilities and, most importantly, local farms. The biogas plant's biogas digestate is an excellent substitute for artificial fertilisers for local farmers.
