Megjegyzések:In the present study we examined the carbon footprint of a biogas power plant in eastern Hungary, and the economic aspects of its operation. About 65% of the raw materials are transported from within a 12 km radius of the surrounding area; however, the remaining 35% arrives from distances greater than 90 km. In 2013 - taking into consideration the complete life cycle of the power plant - the GHG (greenhouse gases) emission linked to each operational phase was 208,173 kg CO2 equivalent, which is only 6.3% of the emission accompanying the production of the same quantity of energy in the Hungarian energy structure; therefore, from an environmental perspective, the energetic utilization of biogas is quite favorable. It became clear during an investigation into the economic aspects of the power plant's operation that in the current conditions its operation is on the margins of sustainability. The acquisition of raw materials must be rethought and rationalized. This can be achieved by 1) the replacement of the relatively expensive selfproduced feedstock by easily fermentable (bio) waste materials, and 2) the radicalreduction of transportation distances. Moreover, it is imperative to find possible ways to utilize the surplus thermal energy and the sale of the fermented manure (biomanure) produced.

Megjegyzések:In our study, we examined the annual carbon footprint and energy balance of a Hungarian biogas power plant with a power output of 0.637 MW in 2013, with reference to the complete life cycle of the biogas production. The life cycle analysis (LCA) considered the emissions of greenhouse gases (GHG) during the production of feedstock and its transportation into the power plant, during the operation of the factory and during the process of rendering the discarded waste materials harmless. We established that the highest GHG emissions related to the feedstock production in which both the use of machines and N2O release from the use of artificial fertilizers played an important role. In 2013, the power plant produced 4347.21 MWh electric power and 4607.89 MWh thermal energy. The carbon footprint of the complete energy production life cycle was 208173 kg CO2 equivalents (CO2e). If the regular Hungarian energy structure produced such a quantity of energy, GHG emissions would be 15 times higher. Therefore, the energy balance of the power plant is positive; in contrast to its 8955.10 MWh energy production, its energy requirements were merely 2720.26 MWh, of which 1520.60 MWh as thermal energy served to heat the digesters. Unfortunately, more than 50% of the produced thermal energy is currently wasted; therefore, in the future, it is important to find a solution for the proper utilization of this valuable energy.
