Organic residues valorization

Insects offer a unique opportunity to address organic waste disposal challenges. They can recover valuable nutrients and bring them back into the food value chain, contributing to a circular economy.

A wide range of organic materials including agricultural residues, food industry byproducts and kitchen waste can be suitable for rearing insects.  BITS offers process technologies to transform 50 to 1000 tons of organic residues per day into high value and safe ingredients for animal feed.

Agricultural residues

On farm level, there are parts of fruits and vegetables that are removed from the food value chain, because they do not fit the specifications. Normally these residues are rich in sugars and micronutrients that are important for insect growth. 

Grains & bran

Primary processing of grains often includes the removal of bran. But also using grains in fermentation results in byproducts like distillers or brewers spent grains. Their large availability and relatively high starch and/or protein content makes them a valuable feed ingredient for insects. 

Starch/sugar crop by-products

While processing tubers (e.g. potato) or sugar cane/beet, several byproducts like peels, cut-offs, pulp, molasse, vinasse and bagasse can occur. Since these materials are normally relatively rich in starch or sugars, they are a valuable source of energy for insects.

Dairy waste

The manufacturing of dairy products from milk including cheese and yogurt generates a large amount of high-strength waste byproducts such as whey, buttermilk, or rinsing water. Their relatively high protein and lactose content makes them a suitable ingredient for insect feed formulations.

Bakery and supermarket discards

Every day, large amounts of fruits, vegetables, bread and dairy products are discarded from retail stores, because they cannot be sold anymore. Although the composition might vary from day to day, food discards are a cost-effective source of feed for insects. 

Kitchen waste

Millions of tons of kitchen waste from restaurants, hospitals but also individual households are generated every year, which imposes a big disposal challenge, especially for large cities. After removal of oil and water, kitchen waste contains all nutrients needed for growing larvae efficiently and economically.
