Each batch of digestate contains readily available nitrogen, phosphate, potash and a range of vital trace elements. Because the nutrients are naturally plant‑available, crops can absorb them quickly and efficiently, supporting strong growth while improving overall soil health. Digestate can be stored on farm until spreading, offering flexibility around seasonal operations. This approach creates a genuine circular model: organic material collected from UK households, retailers and businesses is processed through AD and returned to farmland as a valuable fertiliser. What begins on the farm ultimately comes back to support the next crop cycle.

Biogen’s AD operations supply farmers with a reliable, consistent and environmentally responsible alternative to manufactured fertilisers. Using digestate reduces dependence on synthetic products, lowers carbon footprint and supports the transition to more sustainable agricultural practices.
