Insect protein as a novel and sustainable feed ingredient
The research presented in the WWF-UK report highlights the huge potential for insect farming in helping to tackle the climate and nature crisis.
In addition to reducing deforestation risk, insect farming has the advantage that many insects are biological waste processors, helping to recycle and decompose material.
Insects can be reared from a vast range of feedstocks, or substrates, and can process surplus food, by-products and other raw materials which might otherwise go to waste, therefore supporting a circular economy.
The research estimates that projected total demand for insect meal from the UK’s pig, poultry and salmon sectors could reach around 540,000 tonnes a year by 2050, legislation permitting. This could result in about 16,000 tonnes of fishmeal and 524,000 tonnes of soy being replaced.
Around 150,000 hectares of land is required to produce this amount of soy annually, almost the size of Greater London. Using insect meal to feed fish and livestock could therefore cut the UK’s future soy footprint by a fifth, or Tesco UK’s entire 2018 soy footprint!
