Biogas, circular economy |  Future-oriented use of manure

boss This is a leader. The editor expresses the newspaper's position.

46 farmers in Trøndelag An agreement is signed to deliver the fertilizer to the new large biogas plant Malm Biogass in the municipality of Steinker. This is a promising development.

Farmers own together 20 thousand acres of cultivated land in the area, which in this context is a spreading area for grass and grains. They will mainly deliver cattle manure, a large amount of pig manure, and some poultry and sheep manure. In addition, Salmar, which operates two fish plants in the region, will deliver the sludge from agriculture as raw material to the biogas plant.

From dung to environmental benefits: biogas production is increasing in Norway

In a more circular circle More biogas is produced on the basis of dung. It improves soil health and reduces greenhouse gas emissions from the agricultural sector, confirms Gunn Ede, head of department at the Norwegian Agriculture Directorate.

Farmers distribute fertilizers It is returned to biogas plants after processing, then in the form of nutritious biofertilizer, which is used again in the fields. This process reduces emissions of methane, nitrous oxide and carbon dioxide.

In this way, livestock production becomes…The resulting waste and cultivated soil are part of a climate- and nature-friendly solution, and ultimately also for the sludge and waste generated by the aquaculture industry. The latter will contribute to better compost due to the higher nitrogen content.

The solution is to win. NMBU estimates that up to 30,000 tons of carbon dioxide equivalents could be reduced. It will reduce climate emissions in Steinker by 20 percent, and agricultural emissions in the municipality by 37 percent.

It costs, of course. Farmers provide attractive spreading areas and should pump 40-50 million in industrial investment into Stinker. They should also expect their share of financial gains from the investment.

But it also costs To abstain. The former leader of Norges Bundelag, Lars Peter Bartnes, is the president of Beitstadfjorden Sisu, a cooperative of 46 farmers in Trøndelag. – As landowners and farmers, we have to equip ourselves so that we can manage the land well, he tells the nation.
