BSI PAS 110: Producing Quality Anaerobic Digestate

What is PAS 110?

PAS 110 is an industry led specification which sets out the minimum quality required for whole digestate, separated liquor and separated fibre, which may be used as a fertiliser or soil improver. Meeting PAS 110 quality and other criteria enables the producer to demonstrate conformance to PAS and consistent quality. This process takes digestate from ‘waste’ to ‘product’ classification.

 

What are the benefits of PAS 110 certification?

The purpose of this PAS is to remove a major barrier to the development of AD, namely, by encouraging markets for digestates. It is an industry specification against which producers can check that the digested materials are of consistent quality and fit for purpose. This PAS, together with other supply and demand market development measures, opens new market opportunities and encourages more sustainable practices in the management of biowastes and biodegradable materials.

 

How does it work?

PAS 110 requires the producer to implement a management system which ensures that digestate is fit for purpose. This involves Hazard Analysis and Critical Control Point (HACCP) planning to identify and control hazards associated with adverse effects on the environment and on plant health.

WRM can develop a tailored PAS 110 management system including core documents such as the Quality Policy, Standard Operating Procedures and the HACCP Plan. WRM also conduct internal audits against the standard and provide support through the external certification process.
