Biofertiliser

What leaves a digester or a sludge line is not only gas. The digestate and the dewatered sludge carry nitrogen, phosphorus, and organic matter that an estate or a farm can return to land, if the analysis says the material is fit for that use.

This is a product pathway, not a claim that every sludge is a fertiliser. Moisture, contaminants, and the agronomic rate still have to be measured. That measurement, including when it is run beside a crop trial, is a biofertiliser assessment. The platform can trace the batch from the plant to the field. The nutrient numbers come from the sample, not from the software.
