Recovering nutrients from food waste


Exploring the use of digested food waste as a soil improver and biofertilizer is currently being investigated by CHAP member, IntelliDigest.

The company was recently awarded a series of grants totaling £245,000 to fund the further development of its iDigest automated bio-upcycler, which recovers nutrients from food waste. The aim is to progress the design, manufacture, and overall commercialization of the technology.

This follows the completion of a scoping project undertaken last year alongside CHAP and partner Rothamsted Research, which investigated the suitability of recycled nutrient outputs for the hydroponic cultivation of salad leaves. The project was funded through the STFC Food Network Plus.

Founder and CEO of IntelliDigest, Dr. Ifeyinwa Kanu, said: “We want to empower global food sustainability; eliminating edible food waste whilst upcycling inedible food waste back into food production in the most efficient way.

“iDigest is one of our solutions – an on-site processor that transforms food waste into a nutrient concentrate that can be used as an alternative to traditional fertilizer products.
