Holsworthy recycles up to 76,000 tonnes of the south west’s household and commercial food waste each year and through its anaerobic digestion (AD) process, produces 70MWh of clean, green and eco-friendly electricity per day - enough to power 6,000 homes. 

It has now 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, and is managed by the Anaerobic Digestion and Bioresources Association (ADBA), the UK’s trade body for AD.

“We’ve always been ahead of the curve in terms of innovation and processes, and the main driver for applying for ADBA certification is our wish to maintain continual improvement,” says Tom Brown, Compliance Officer.  “Certification goes some way to demonstrating that we are on top of things while the compliance system ensures that any changes to the way we operate are made the right way.”

And Mike Lowe, Operations Director added:  “Naturally we’re delighted to be one of just three plants in the whole of the UK to be awarded this certification and I am extremely proud of our on-site compliance team and all members of staff whose high standards of management and professionalism enable us to deliver safe and sustainable practices each and every day.”

Sam Hinton, Technical Support Manager at ADBA said: "We congratulate Andigestion for achieving the ADCS certification, which demonstrates their commitment to operational excellence. They will reap obvious benefits from the recognition - not only improved performance and productivity, whilst adhering to high environmental, health and safety standards, but also confidence from their employees, customers, regulators, insurance companies and neighbours. We're also delighted that, as the first plant to achieve ADCS certification in 2020, they lead the way in showing other operators how to conduct business during these uncertain times."

Our site in Bishops Cleeve near Cheltenham, Gloucestershire, which recycles up to 34,000 tonnes of food waste a year, will also be assessed for ADCS certification.  Through the production of biomethane gas which is fed into the national grid, Bishops Cleeve contributes enough energy for around 10,000 homes a year. The by-product of the process from both plants – a mineral-rich, liquid biofertiliser – is used by local farmers as a sustainable alternative to carbon-intensive chemical fertilisers.
