The thesis examines problems of biogas producted in biogas station. The aim of this thesis is to research possible options how to increase effectiveness od production energy from biogas in biogas unit. In first captions I dedicate theoretical informations about renewable resources and options of their exploitation. We describe the process of formulation biogas, basic ingredients, materials, conditions suitable for production. In the last caption I dedicate description of biogas station in Detva. Also I suggest otions for increasing effectiveness production energy of biogas based on cinditions found this biogas station in Detva.
