Welcome to Warrens Group. Your essential green partner…

Warrens Group is working with the public sector and private companies towards the ultimate goal of eliminating food waste in landfill, which is both costly and harmful to the environment.

As an alternative we use biotechnology via anaerobic digestion to treat food waste and organic materials – creating valuable resources and clean, green energy.

For our farming customers we provide a safe secure disposal of your waste products, whilst also creating renewable energy and biofuels.
