Humic wastes originate in Vitana Works Kralupy n. V. They create humic acids and are contained in plant products. This factory produces Klasik soup stock made from soya-bean, keratine, grain protein, HCL 20 % and H2O. These raw materials are hydrolysed (pressure 20 kPa and temperature 120 deg C - 24 hours), after which follows neutralization and filtration. The trials were carried out on rats, chickens and fattening pigs. Results indicate that humic wastes can partially substitute animal meal (1 %).
