At the brewery itself wet draff are mixed up with yeasts and other organic sub-products collected in the brewery, with a mineral corrector and an ensilage preservative; non proteinic nitrogen can also be added, as well as kaolinite and remainders from other food industries. The same technique can be applied if the breweries draff are substituted by any other food industries sub-product usable for cattle feeding. A good basic foodstuff for animals is obtained, while eliminating the pollution due to food industries sub-products. |
