 Poldanor’s strategy is based on the development of efficient and sustainable production and respect for the environment at the same time. Therefore the company systematically invests in environment-friendly technologies. Its strategy stresses the importance of Corporate Social Responsibility, both with reference to the external community and the company’s employees. This fact is confirmed by the receipt of such awards as “Pantheon of Polish Ecology” and “Business Fair Play”.
The Company started working on the concept of biogas plants in 1999. In 2005, Poldanor built and launched the first agricultural biogas plant in Poland, and thus began the implementation of a programme which provides for the development of a total of 14 such plants next to pig farms operated by the company. To 2011, Poldanor has set up 8 working biogas plants in Poland, with a total power of 7.4 MWe.
In 2010, the plants generated about 33,000 MWh of “green” electricity, corresponding to the demand of approx. 10,000 households, which helped reduce emissions of greenhouse gases by the equivalent of more than 68,000 tons of carbon dioxide. It is expected that in 2011 the plants will produce 50,000 MWh of electricity (16,000 households) and an emission reduction of 170,000 t.
The planning, design, and supervision of development of Poldanor’s biogas plants, as well as their operation, are managed by a team of qualified experts from the energy, construction, and biogas production sectors.
Poldanor actively cooperates with institutions and organizations dealing with renewable energy, as well as with academic research facilities in Poland and Denmark, with regard to the promotion and development of Renewable Energy Sources. |

Agricultural biogas plant in Nacław, with electrical capacity of 625 kWe and thermal capacity of 680 kWt, opened 7 June 2010
Location:
- Town/village: Nacław
- District: Polanów
- County: Koszalin
- Province: Zachodniopomorskie
Project description:
The agricultural biogas plant in Nacław produces biogas and generates electricity and heat through its combustion. The input material is composed of liquid pig manure mixed with supplementary components: corn silage, glycerine and waste from crop production. The type and quantity of substrates used are monitored daily, so as to obtain the highest efficiency of the system and equal distribution during fermentation. The biogas is produced in a process of mesophilic digestion (fermentation) at a temperature of 37˚C, in anaerobic conditions. The biogas produced in the fermentation process is combusted in a cogeneration unit generating electricity and heat. The resultant electric power is partly consumed by the plant (5–10%) and the adjoining pig farm (10–15%), and the remainder (75–85 %) is sold to a power company. The heat recovered from engine cooling is used for technological processes of the plant and will be supplied to external customers. The Nacław biogas plant is composed of the following facilities:
- component storage area with a feeder, with total area 288 m2
- component storage tank no. 1 with capacity 32 m3
