Nordic meat producer HKScan has been putting into place different measures to increase industrial symbiosis. Food industry manufacturing processes are optimised and surplus food is redirected to feed people or animals to prevent food waste.
Meanwhile, the parts of the animals that are not sold as food are used for pharmaceuticals, food ingredients, animal feed, pet food and biodiesel for renewable energy. Wastewater sludge and cow stomach content are turned into biogas, resulting in renewable energy for car fuel, electricity and heating and nutrients for soil improvement and organic fertilisers.
