Danger, danger - pollution. But Pruex has the answer

Pruex offers a solution by replacing toxic, pathogen-laden sludge with beneficial bacteria that safely stabilise waste on-farm. Our soil bacteria-based approach reduces ammonia, methane, and pathogen load—avoiding reliance on external sludge. Pruex ensures that sustainable intensification enhances, rather than harms, soil, water, food safety, and long-term farm resilience.

Pruex: Replacing Toxic Sludge with On-Farm Biosecurity Solutions

The growing alarm over sewage sludge containing PFAS, pharmaceuticals, microplastics, and hormone disruptors highlights a serious flaw in how Britain manages waste and fertiliser use. Farmers face a false choice: apply cheap but contaminated sludge, or pay for synthetic inputs. Pruex offers a third, safer path — one that protects both productivity and the environment.

Since 2016, Pruex has developed bacterial systems that allow waste to be treated and stabilised on-farm using natural microbes, rather than relying on sludge from wastewater treatment plants. By applying beneficial bacteria at key points — water troughs, bedding, and slurry channels — we replace pathogenic, fermentative, and polluting microbes with controlled, respiration-dominant microbial communities. This process retains nitrogen as ammonium, reduces ammonia and methane emissions, and minimises the formation of toxic byproducts.

Unlike sewage sludge, Pruex slurry contains no unknown contaminants. Instead, it enriches soil health, supports biodiversity, and improves silage quality — all while improving animal health and reducing the need for antibiotics.

Pruex shows that farmers don’t have to compromise. By managing waste at its source with trusted microbes, we can end the dependency on hazardous sludge and build a truly circular, safe, and productive agricultural system.
