To revive the local economy and reduce dependence on fossil fuels, Polish farmers have well thought of installing a biogas plant of 1.99 Megawatts. The plant is located in the town of Rowa Mazowiecka, 80 km south-east of Warsaw. The next step will be connecting the system to the local district heating network for the residents of the area.
The plant, which is located in the village of Konopnica, uses an innovative system of dry fermentation. This technology is capable of transforming agricultural waste into a renewable biogas which is used as a fuel. Like Italy, Poland also has environmental objectives, in accordance with the "Energy Policy 2030" strategy, an extensive use of biogas so as to further diversify energy sources.
The biogas product is used to drive two approved GE Jenbacher J320 gas engines ecomagination. GE technology generates reliable electrical and thermal energy, with an electrical efficiency of 40.8% and a total efficiency of 86.6%.
There dry fermentation is a new process for the production of biogas come on Organic waste. During this process there is no extraction or addition of material from the fermentation cell, in this way it is possible to treat substrates with a high content of dry matter, there is no need to mix the waste nor to use pumps, it follows thus an energy saving in the fermentation process.
Another advantage of the dry fermentation is that the production of biogas continues even if in the biomass selected there are foreign or inert substances such as plastics or large wooden components.
The Konopnica plant is part of the Bioenergy project, a plan by which we would like to relaunch the local economy. With the Bioenergy Project, farmers are given the opportunity to exploit all that the land offers for the production of biogas.
