The nutrients within the digestate are readily available for plants to use as the bacteria have broken the nutrients down into available forms which the soil organisms would otherwise have to do. The availability of nitrogen can be up to 90% in the biofertiliser.  

The biofertiliser is near odourless and is a homogenous material that can therefore be applied with accuracy.

The digestate can only be used beneficially as a fertiliser and soil conditioner on agricultural land if the feedstock is 'clean' for example, from source-separated food processing waste or industrial food processing.  

The digestate from animal by products must be pasteurised before going to land.   This ensures the eradication of Salmonella and E.coli where within a specified sample.  

The enhanced quality of the biofertiliser can be a main driver for a project.   This was the case for the Scottish plants which Greenfinch built in south-west Scotland.   The main aim of these plants was to reduce the level of faecal indicator organisms (FIO) entering the bathing waters, located within a few miles of the farms.
