Biofertiliser Certification Scheme

OF&G provides the inspection and certification of biofertiliser to PAS 110 and the Anaerobic Digestion Quality Protocol (ADQP) under the Biofertiliser Certification Scheme (BCS)

Publicly Available Specification (PAS) 110 was developed by the Waste and Resources Action Programme (WRAP) to help create a market for the use of anaerobic digestate (AD) as a renewable fertiliser.

The Biofertiliser Certification Scheme (BCS) provides assurance to consumers, farmers, food producers and retailers that Biofertiliser produced from anaerobic digestion processes is safe for human, animal and plant health.

Biofertiliser is the name adopted for the digestate certified under the BCS for end-of-waste and quality assured status.

What is PAS 110?

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 rich in nutrients and used as a renewable fertiliser.

The British Standard Institution (BSI)’s publicly available specification (PAS 110) provides a baseline quality specification for digestate, ensuring it is safe and reliable to use.

PAS 110 includes requirements about how food waste and other materials can be processed and is one of the fundamental pillars of the BCS.

Close to five million tonnes of digestate accredited under the BCS is produced in the UK every year and used as renewable fertiliser in agriculture, field-grown horticulture, forestry and land restoration.

The main reason to certify the process to the BCS is to meet the ’End of Waste’ criteria in the UK Nation that the process is based. Once certified, the compost becomes a ‘product’ rather than a waste and waste regulations no longer apply. To do that the process needs to be compliant with:

PAS110

BCS Scheme Rules – details how the BCS operates and include procedures for application to the scheme, product complaint investigation, etc.
BCS Position of Technical Requirements – The Biofertiliser Certification Scheme interpretation of PAS100, and the BCS Scheme Rules requirements .
The End of Waste Position for the UK Nations where the process is based – these set out when material has been fully recovered and ceases to be regarded as waste .

—

The End of Waste Position for England is set out in The Anaerobic Digestate Resource Framework
For Wales it is GN023 (End of Waste: Anaerobic Digestate produced from source-segregated biodegradable waste) .
For Scotland it is SEPA’s End-of waste regulatory position statement for digestate.
And Northern Ireland still use the Anaerobic Digestate Quality Protocol.

Why certify with OF&G (Organic Farmers & Growers)?

OF&G has been involved with the development of the BCS from the outset in 2007/8 alongside the Renewable Energy Association (REA) and WRAP.
Consequently, we have industry leading experience in the certification of PAS 110 and the ADQP. We certified the first BCS licensee in 2011 to PAS 110:2010
OF&G has their own dedicated team of independent inspectors
OF&G works hard to ensure its voice is heard on behalf of you, our licensees
OF&G offers practical, experienced guidance for your business

Why is Biofertiliser certification necessary?

Biofertiliser produced in the anaerobic digestion process can be a useful, cost-effective and sustainable source of soil nutrients.

However, their use on the land needs to be regulated to ensure the public, farmers, food producers and retailers can have confidence in the safety of the process.

Where digestate is produced to the BSI PAS 110 quality standard, everyone can have confidence that its use as Biofertiliser is safe and has been checked by an independent approved body.

OF&G provides the inspection and certification of Biofertiliser to PAS 110 and the ADQP under the BCS. This is undertaken on behalf of Renewable Energy Assurance Ltd (REAL), a subsidiary of the REA.

To achieve successful certification, facilities producing the digestate will need to meet the requirements of the BCS regarding inputs, processes and the Biofertiliser produced.

The benefits of going through this process are that the digestate resulting from anaerobic digestion can safely be used by farmers as a good source of sustainable fertiliser.
