The slurry from a newly erected pigsty on a farm in Varazdin, Croatia, with 130 sows and 2,800 porkers, is forming the basis for biogas energy production.
The 250kW plant from German manufacturer Weltec Biopower perfectly suits the farm’s cycle of food production, liquid manure utilisation and energy production in the form of power, heat and fertilliser.
In addition to a subsidy for the construction, the farmer was able to base the investment decision on a fixed feed-in tariff of e0.19 (16p) per kilowatt-hour of power fed in during the next 14 years. This income forms a solid basis for diversifying his business.
Weltec’s Croatian sales partner considers the development of such a family operation as a trend-setting concept in the country, where a focus on biogas for heat and power production is on the rise.
