‘PAS110’ was developed by WRAP to help create a market for the use of anaerobic digestate as a renewable fertiliser.
- Controls on input materials and the management system for the process of anaerobic digestion and associated technologies
- Minimum quality of whole digestate, separated fibre and separated liquor
- Information that is required to be supplied to the digestate recipient
Overview
Processing food waste and other organic materials such as livestock manures and slurries in an anaerobic digester (also known as a biogas plant) produces biomethane, which can be used as a source of renewable energy, and digestate. Digestate is a slurry like liquid that is rich in nutrients and used as a renewable fertiliser.
The British Standard Institution’s Publically Available Specification (BSI PAS 110) provides a baseline quality specification for digestate, ensuring that it is safe and reliable to use. PAS110 includes requirements about how food waste and other materials can be processed, and is one of the fundamental pillars of the Biofertiliser Certification Scheme.
Close to 2 million tonnes of digestate accredited under the Biofertiliser Certification Scheme are produced in the UK every year. They are used as renewable fertilisers in agriculture, field-grown horticulture, forestry and land restoration.
PAS110 came into effect on 31 July 2014.
