Case study: Selko, Noblesse and Looop work together to keep nutrients in the food chain

A recent collaboration between Noblesse Proteins BV, Looop and Selko is one example of how we connect businesses and maintain food by-products within the feed chain.

A recent collaboration between Noblesse Proteins BV, Looop and Selko is one example of how we connect businesses and maintain food by-products within the feed chain, to help build more circular food systems. Noblesse Protein transforms by-products into high-quality proteins and fats for the animal feed, biofuel and fertiliser markets.

It is collaborating with Selko Feed Additives and Looop, a company specialising in extracting the maximum value from by-products from food and the fermentation industry, to divert an animal by-product from biogas production towards feed ingredients.

One challenge in upcycling by-products is ensuring their safety and quality is preserved, by implementing effective feed safety and preservation solutions. This is where Selko comes in. Noblesse ran various dose-response tests with various industry preservatives to find the best solution; the company selected Selko Revalet Super, as it provided the most cost-effective and broad spectrum. Preserving nutritional value is also critical to keeping by-products available for feed production. As microbes consume nutrients at an accelerating speed, deactivating them as early as possible is important.

In addition to treating products with Selko Revalet, Noblesse collaborated with Looop to upcycle the by-products and get them to market. Following its “Looop Ladder,” the company utilises by-products to develop alternative resources for, among others, the animal feed industry.

For Noblesse, it is important to make all incoming proteins available to the feed market rather than supplying them to the bio-energy industry. With Selko Revalet Super we found
a high efficacy when applied in lower dosages. The product helps to preserve the nutritional value of our by-products.
