Turning brewing by-products into feed and fertiliser

These by-products from brewing processes can be valuable inputs for farmers. In 2022, 97% was used as animal fodder and 3% as fertiliser. 

In Malaysia, we have been supplying these by-products for livestock feed since 2019, amounting to more than 17,000 tonnes of spent grains and more than 3,000 tonnes of spent yeast in 2022. Some was used for cattle fodder and the rest became an  ingredient in a protein-rich feed. The bioconversion process used to make this feed also uses our filter material and waste yeast to
cultivate black soldier fly larvae into insect meal and insect oil as a source of protein for a wider range of animals.
