Eco-friendly heat sources from the biogas plant at the Agricultural and Pomological Experimental Farm at Przybroda

The official opening of the district heating system for the residents of the village of Przybroda powered by "green heat" from the biogas plant at the PULS Agricultural and Pomological Experimental Farm at Przybroda took place on November 21.


During the meeting, a modern district heating system powered from the biogas plant was presented as an example of a pro-ecological and efficient system using renewable energy sources. The installation at the Experimental Farm of the Poznań University of Life Sciences produces as much heat annually as we would get from burning 800 tons of coal a year  - with the significant difference that it does not pollute the air. The innovative biogas plant with an energy output of 499 kW and a heat output of 560 kW at the Przybroda experimental farm converts animal waste and other agricultural biomass into "green" electricity and heat in a very efficient way, with the final product also being a sensational quality fertilizer material.

"Our biogas plant is basically ‟omnivorous”. The input can be bio-waste, basically everything from agriculture and processing except for wood and its waste. And the heat, you could say, is a by-product here, which currently reaches the homes of 58 families in the village and all the buildings of the university's experimental farm" - says Prof. Jacek Dach, head of the Ecoenergy Laboratory at the Poznań University of Life Sciences.

This is not the only technology for the bioenergy sector developed by scientists at the Poznań University of Life Sciences. Work is also currently underway on a system for extracting biomethane from bio-waste, on biohydrogen and on extracting energy from biomass. "The Poznan University of Life Sciences is a leader in new technologies for the bioenergy sector - we already have tangible successes in this area, but also great potential, which we will develop," PULS Rector Prof. Krzysztof Szoszkiewicz said at the meeting.

There are 140 agricultural biogas plants in Poland. According to Prof. Jacek Dach, the potential of our country to contribute to such installations is much greater. According to calculations by scientists from the Poznań University of Life Sciences, Poland could have 10-12 thousand similar biogas plants, which are capable of supplying local residents with green and cheap heat.
