The assignment included the assessment of the technical and economic feasibility of a biogas plant. The plant should be set up on an existing landfill site and integrated into the existing infrastructures.
Different waste streams like organic household waste, kitchen waste, sewage sludge; agro-industrial waste were intended to be turned into renewable energy by the anaerobic treatment. The biogas produced by the biogas together with landfill gas will be treated thanks to a membrane filtration system where it will be processed to natural gas quality and fed into the natural gas grid. The heat necessary for the processes will be recycled from the gas cleaning unit thanks to heat exchangers, and used for heating of the digesters.
The plant will be constructed in such a way that extension can be easily undertaken in the near future in order to push up the waste treatment capacity from 23.000 tons/year up to 55.000 tons/year.
