Biofertiliser is a stabilised nutrient rich product, which is a direct replacement for fossil fuel derived fertiliser. The AD process both stabilises and sanitises biofertiliser to ensure it is safe to apply to crops.

Biofertiliser Analysis
Biofertiliser contains a broad spectrum of macro and micro nutrients ideal for agricultural applications. The nutrient analysis ranges are:

Nutrient Content
Dry Matter 2% to 7%
Nitrogen (N) 5 to 7 kg/m3
Phosphorus (P2O5) 0.2 to 0.37 kg/ m3
Potassium (K2O) 2 to 2.5 kg/ m3


The Westwood AD plant is located in Northamptonshire. Feedstock for this plant is 49,000 tonnes of food waste per year, from which the plant can produce around 42,000 cubic metres of biofertiliser. This supplies the requirements of almost 1,000 hectares of arable land per year, growing some 10,000 tonnes of milling wheat, which is sufficient to produce 9.8 million loaves of bread!
