PRESS RELEASE: Bore Hill Farm becomes first English AD plant certified under performance scheme

  • Wiltshire plant recycles inedible food waste into renewable energy and biofertiliser 
  • Bore Hill Farm Biodigester becomes second UK plant certified under new AD Certification Scheme 
  • Plant owner Thomas Minter says certification “is testament to the hard work of staff and a great achievement” 

Bore Hill Farm Biodigester has become the first English anaerobic digestion (AD) plant to be certified under a new certification scheme that recognises good operational, environmental, and health and safety performance at UK AD plants. 

The plant, based in Warminster in Wiltshire and run by Malaby Biogas, processes inedible food waste to create biofertiliser and renewable heat and power. It generates enough green electricity to power 2,500 houses.   

The plant has been certified under the Anaerobic Digestion Certification Scheme (ADCS), an industry-led initiative designed to raise standards and recognise good practice in the running of AD plants. The scheme provides an independent audit process and report that help operators to ensure they are meeting required standards and identify areas for improvement. The ADCS has been developed in collaboration with a range of industry stakeholders including regulators, insurers, investors, and operators, and is managed by the Anaerobic Digestion & Bioresources Association (ADBA), the UK’s trade body for AD. 

Bore Hill Farm becomes the second UK plant to be certified under the scheme following the certification of Granville EcoPark in Northern Ireland earlier this year. 

Thomas Minter, Director of Malaby Biogas, who run Bore Hill Farm, said: 

I am very proud of the work our staff have put in to enable us to achieve certification so smoothly. It is a testament to the management systems we have developed, the innovations and optimisations on site and everyone’s professionalism that have allowed us to take a leading position in this new scheme. Seeing regulators and insurers so actively involved in the development of the ADCS has been encouraging and now we have the basis for them to help in supporting and promoting the scheme across the industry. This is a milestone we are proud of.

Nick Johnn, Director at Aardvark Certification Limited, the ADCS’s official certification body, said: 

Mr Minter and the team at Malaby Biogas provide a great example of the high standards which can be achieved within the AD sector, from design and construction of a good AD plant through to operational practices which minimise health-and-safety and environmental risks. We are delighted to be able to issue certification to the ADCS to Malaby Biogas in recognition of the efforts they have put into ensuring their operations meet the high standards set by the scheme criteria. We are pleased that they have been able to realise the benefits available to AD operators in the UK through achieving certification to the ADCS.

Charlotte Morton, Chief Executive of ADBA, said: 

We’re delighted to see the Bore Hill Farm Biodigester become the first English plant and the second in the UK to be certified under the ADCS, which is a vital scheme for making the UK AD industry a mature and thriving sector that delivers consistently excellent projects. ADBA will continue to speak to AD operators about the many benefits of the ADCS both for operators themselves and for the wider industry, including increased support from politicians, regulators, insurers, and investors.

Malaby Biogas has also announced a new partnership with insurance brokers Jelf.  

Thomas Minter said of the new partnership:  

Jelf have been actively supporting the AD industry to achieve improved insurance cover and the ADCS has been an important component in achieving recognition for excellence in plant operations.

Carl Gurney, Renewable Energy Director at Jelf, said: 

It was fantastic to see Malaby Biogas achieve their ADCS certification. The plant is truly first-class and a credit to the hard work put in by Thomas Minter and his team. It was a pleasure to work with Thomas and insurers who have delivered on their promise of an excellent insurance policy and improved premiums. The signing of this new partnership with ADCS also demonstrates our continuing support for those working to sustain and strengthen the UK’s anaerobic digestion and biogas sector.
