The food processing industry is subject to increased pricing pressure. And the segment is further complicated by the short life cycles of the products and high demands on hygiene. In addition to that, there is the need to ensure that shelves are fully stocked at all times. The production of food stuffs also results, besides this surplus, in production waste and rejected batches.

These waste products may occur, for instance, in:

• Dairies: whey, wastewater
• Meat and fish processing companies: animal blood, innards, contents of gastrointestinal tracts, fat, animal carcasses, muscles, tendons, skin
• Fruit and vegetable operations: unsatisfactory goods, hulls, peelings, seeds, wash-water
• Breweries: brewer grains, corn dust, yeast, wastewater
• Distilleries: pomace, hulls, peelings, seeds, press cake, wastewater
• Manufacturers of baked goods and candies: yeast, sugar, fat, shells
• Sugar industry: pressed sugar beet pulp
