Horizon Protein, a spin out from Heriot-Watt University, is working with the Scottish malt whisky industry to produce a low cost locally sourced sustainable fish (salmon) feed from recovered barley protein.

Currently, the UK has a high dependency on imports for feed ingredients, with roughly 60-90 per cent of feed ingredients being imported, said Dr Aboubakry Diallo, from Horizon Proteins, during his talk at Aquaculture UK.

Finding a more sustainable and local alternative through underused proteins has therefore been Horizon\\\'s vision.

The Scottish malt whisky industry produces 225 million ipa malt whisky each year and is valued at 3.8 billion a year. From this production there is 30,000 tonnes of protein that can be used.

In order to recover the protein, Horizon has a patented process whereby the leftover pot ale from whisky production is separated into yeast for feed, protein for fish food (barley) and a carbohydrate rich stream.
