Producing quality compost and digestate (biofertiliser)

Compost and biofertiliser: what’s the difference?

Quality compost and biofertiliser are both made from biodegradable waste that has been separated at source. But the process of producing compost is aerobic - requiring oxygen to be completed successfully, while the process of producing biofertiliser is anaerobic, requiring an absence of air. 

There are strict standards governing the materials that can be used to produce quality compost and biofertiliser for use in agriculture. These are set out in the British Standards Institution’s BSI PAS 100 (for compost) and BSI PAS 110 (for biofertiliser). Independently-audited schemes are available to allow producers to certify their processes and outputs to these specifications.
