Salmon farming is an energy-efficient way of producing meat, particularly when compared to the farming of land-based animals.
Nonetheless, we are working across our business using a life cycle assessment approach to become more energy efficient. This will not only cut costs but reduce the environmental footprint of the part of our operations which relies on energy from non-renewable sources that emit carbon dioxide.
More environmental benefits
The salmon industry has always sought to find the lowest possible input of feed resources. The use of high-energy-extruded diets means that less feed is used, and therefore less raw materials, to produce one kg of salmon. Reducing the amount of feed also means less use of transportation and thereby reduced CO2 emissions.
In addition, due to the excellent physical quality and high digestibility of extruded diets, there is less waste from production such as broken feed pellets and faecal material. This again reduces the discharge of phosphorous and nitrogen from farms.
