Nutrients recovered in manure processing

In summer 2020, a total of 510 tonnes of separated pig manure was transferred from Huittinen to a grain farm in Sastamala. With the solid manure fraction, the crop farm got valuable phosphorus and organic material in its fields. At the same time, nutrient runoff into the Baltic Sea was reduced. Improving the use of manure is an important part of HKScan’s Zero Carbon climate plan.

In the 2020 Manure Pilot, a total of 510 tonnes separated pig manure from Emomylly group was transferred to a crop farm in Sastamala. This amount of manure is calculated to contain some 1,000 kilos of phosphorus.

Nutrient recycling with manure separation

Manure separation is an important part of the pilot. Separation allows more precise use of phosphorus and nitrogen fractions. It also reduces transportation costs as moving liquid from one area to another is expensive.
Phosphorus is a nutrient that remains in organic solids while nitrogen is separated into the liquid.

In the Manure Pilot, nitrogenous liquid was left on the Emomylly farms in Huittinen. Phosphoric organic separation fraction was transferred by trucks to a nutrient-deficient grain farm in Sastamala.

TEMPORARY STORAGE OF SOLID FRACTION ON A HARD SURFACE WORKED WELL, SAYS KAI HUOVINEN, MANAGING DIRECTOR AT EMOMYLLY OY. 

 

The Manure Recycling Pilot was implemented by HKScan, Emomylly, Raisio and the John Nurminen Foundation.
