The biogas plant in Jordberga, just outside Trelleborg, accounts for a significant share of the region鈥檚 biogas production. The facility, which is currently owned by Gasum, produces between 110 and 115 GWh of upgraded biogas each year.
鈥淭he plant is connected to the Swedish natural gas network. The gas can be used locally on the network or transported further via the main pipeline from Trelleborg,鈥� says Site Manager Jerry Linder.
Plant鈥慴ased production
Production is entirely plant鈥慴ased and relies mainly on locally sourced raw materials within a radius of about one hundred kilometres from the site. These consist primarily of by鈥憄roducts from agriculture and the food industry.
鈥淭he material may consist of cereals, silage, screenings from grain handling and flour production, as well as discarded products. In total, around 80,000 tonnes of solid material are processed per year, with a daily capacity of approximately 165 tonnes divided across three lines, 55 tonnes each.鈥�
To minimise environmental impact and improve process efficiency, water is extensively reused. Most water on the plant, including rainwater, is retained within the closed site and used to dilute the material in the process. In addition, part of the liquid fraction from the biofertiliser is reused, which reduces the extraction of groundwater.
Biofertiliser
In addition to biogas, the plant also produces a high鈥憅uality biofertiliser approved for organic farming. This is returned to farmers in the region and helps close the nutrient cycle. The site has five storage tanks for the biofertiliser, with a total capacity of 25,000 cubic metres, before it is distributed further.
On the farm next to the plant, the biofertiliser is separated into solid and liquid fractions.
鈥淭his enables tailored use depending on farmers鈥� needs,鈥� says Anneli Ahlstr枚m from Gasum.
Future plans
Gasum plans to rebuild the plant within the next few years in order to process animal鈥慴ased raw materials as well. At present, the facility only has permission to handle plant鈥慴ased feedstocks, but a new permit is under review.
