Name:
Biogas plant in Nacław

Location (settlement, country):
Nacław village, municipality of Polanów, West Pomeranian Voivodeship, Poland

Brief description of the technology:
The biogas plant in Nacław (in Polanów municipality, West Pomeranian Voivodeship) is one of the latest agricultural biogas plants built by Poldanor SA company. It was launched in June 2010. It is the fifth biogas plant built by the company, making use of expertise and technology solutions proven in previous installations. The biogas plant is located next to the pig farm which belongs also to Poldanor SA. The farm provides the basic feedstock for the biogas plant, which is slurry. The result of the fermentation process is biogas containing 65% of bio-methane and 35% of carbon dioxide. Biogas is burned in a combustion engine with a power generator, generating electricity and heat. Electricity is used to launch agitators, to light up the farm and office buildings. The surplus is sold to the grid and then to individual customers. Heat is used for cooling and heating digesters and for the heating of farm and office buildings. In the nearest future heat will also be supplied to individual houses and public buildings in Nacław through the heat distribution network (currently under construction), which is planned to be 1.5 km long.

Why is it a „Best practice”?
The biogas plant is considered as an example of best practice, because it shows the possibility of using local renewable energy resources for energy purposes. Manure and other agricultural products as well as wastes that are burdensome to the environment can be converted into biogas to obtain electricity and heat, which are subsequently used in the installation, and the excess is sold to the grid. During the fermentation process slurry, which is a waste, is converted into an organic fertilizer containing easily digestible nutrients for cultivated plants. The biogas plant is a distributed source of electricity; hence its operation contributes to ensuring local energy security. Installation based on the use of locally available substrate does not require transport to greater distances. It generates on-site jobs. The biogas plant contributes to the reduction of methane, which is the most aggressive greenhouse gas.
