Reuse of 50 million kilos of brewers' grains per year
Grolsch reuses 99.8% of its waste. Take, for instance, the dregs: the residual malt that remains after all sugars and proteins have been extracted. These dregs have a high nutritional value, which makes it a popular form of animal feed, especially for cows. Every year, we turn 50,000 tonnes of dregs into cattle feed, and 25 trucks visit our brewery to pick up this waste product for reuse every week, adding up to over 1,250 trucks per year.
