FEASIBILITY PRODUCTION OF GASEOUS BIOFUELS FROM WASTE IN THE REPUBLIC OF MOLDOVA

This paper deals with the cost of biogas and syngas produced from biodegradable waste was determined, at different capacities, which correspond to the powers of gas recovery plants for the purpose of electricity production in the conditions of the Republic of Moldova. The evolution rates of the annual cost of gases were determined. There were determined the levelized cost of biogas and syngas, which was compared with the levelized cost of natural gas. In order to ensure the comparability of these costs with that of natural gas, there are considered the levelized costs of biogases equivalent to the combustion heat of natural gas and the cost of natural gas which is one levelized for the same period. The cost of the syngas is higher than the biogas, this is due to the higher production technology cost and the lower heat value of syngas compared to the biogas. The production of gaseous biofuels, from biodegradable waste, in conditions of our country, proves to be profitable in the case of biogas, and of syngas - it is profitable at high powers
