An assessment of the biomass potential of Cyprus for energy production

Abstract

Biodegradable waste in Cyprus predominately consists of the biodegradable fraction of municipal solid waste, sewage sludge, solid and liquid agricultural residues and solid and liquid wastes from food and drink industries. Biodegradable waste is a very important source of biomass. The potential amount of solid and liquid biomass of the specified waste streams was estimated to be 9.2 million tonnes, after collecting data on the waste generation coefficients. Both liquid and solid waste can be used for the production of biogas (BG), which can be combusted for the production of thermal and electrical energy. The potential biogas production was estimated on the basis of Chemical Oxygen Demand (COD) consumption and on the basis of digested mass. The potential biogas production was found to be 114 and 697 million m3 respectively. Further research is required for the improvement of waste generation coefficients. The results on energy production provide an indication of the importance of promotion of anaerobic digestion for the treatment of biodegradable waste to the energy balance of the country. Anaerobic digestion can provide decentralisation of energy production, and production of energy in areas that are in most cases remote
