A family-run company started in Halifax in the 1970's

At the heart of the British meat industry.

About us

Leo Group is one of the UK’s leading specialists in animal by-products and renewable energy. We play a critical role in the food and agricultural industries collecting and processing material – which is converted into meals and oils for use in pet food, cosmetics, oleochemicals and renewable fuel.

A family-run company started in Halifax in the 1970’s, we now employ a workforce of more than 1000 across our operational sites in the UK, Europe and South Africa and export our products worldwide.

Over the last four decades we have been at the forefront of modernising the rendering industry. Every year we collect and process in excess of 1.25 million tonnes of waste material. From this processing operation we produce 130,000 tonnes of protein meal and 70 million litres of purified fats per year. Biopower processes 60,000 tonnes of material annually and creates 55MW of electricity to power 120,000 households.

We are also at the heart of renewable energy with several investments in solar, wind and biomass. We are continually upgrading and investing in our sites to make them as environmentally friendly as possible. The overall aim is for all our processing sites to be run using 100% renewable energy.

The Group is both self-financing and self-sustaining. The key to our success has been sound business acumen, together with a number of substantial business acquisitions. We have a strategy of re-investment in new, efficient and environmentally friendly technologies and equipment, as well as the ability to identify and grasp emerging opportunities ahead of our competitors.

In addition, Leo Group aims to play a key role in the communities in which we operate through jobs and investment and we are a major employer in the areas where our plants are based. We also support charities and good causes in the local community donating more than £1m in the past 10 years and providing grants of up to £2,500 through the Leo Group Community Fund.

Above all providing the best service and quality to our customers and suppliers remains our focus. We recognise our success is hinged on these long-standing relationships, maintaining our reputation as a trusted partner and achieving through quality.
