Farmfood specialises in recycling offal from poultry rendering plants for specific use – in particular for the pet food industry in addition to biogas plants. Production is continuously expanded. Heat-treated offal from animal rendering plants has a pronounced smell that can be difficult to fully remove in mechanical or chemical filters.
Proximity to the town of Løgstør means there are strict requirements for the emission of odorants. The environmental authorities demand a maximum of 10 LE at the plant and 5 LE at its boundary area and carry out annual inspections.
“It’s difficult to remove odours from heat-treated animal offal which gives off many different odorants. With our BBK biofilters, we have found a safe solution with a broad spectrum that effectively removes all odours from production, ensuring great satisfaction among the plants neighbours. BBK performs monthly service visits to the plant and checks cleaning performance and ensures that we meet all environmental standards. Filter systems are built by BBK as a turnkey contract and they have always supplied a quality product at the agreed price.”
Farmfood has urban production in Løgstør and has successively expanded the factory. The special conditions with heat-treated offal from animal rendering place big demands on odour filters. They must have a broad operational spectrum in order to avoid causing nuisance for the neighbours. Throughout the years, BBK has supplied biofilters that will clean up to 100,000 m3 of air/hour. With precise flashing and extraction, they ensure that all odours are removed effectively inside the plant.
