Biogas plant design

The diploma thesis is focused on possibility of usage biologically decompostable wastes in the biogas plant. The first part of this thesis describes principal production of the manure gas and as well concrete biogas plants, where are shown different approaches and technologies. The main target of the thesis is based on biogas plant design for manipulation with biologically communal wastes from VUT v Brno and chosen parts of Brno. To the proper design of the biogas plant precede evaluation of accesible wastes from choosen localities. Since we consider wastes from households, the way of collection of those wastes is designed. The thesis also consider economic balance and assesment of the biogas plant. Investment costs are predicted, process costs are evaluated and as well profit from selling of the electric energy is consider, profits from charges for manipulation with wastes and profits from selling of compost
