About Tamar Energy

Tamar provides cost-effective, sustainable organic waste management solutions through its award-winning network of anaerobic digestion (AD) plants and composting sites.

Tamar transforms organic waste into renewable energy and biofertiliser or compost. "Renewable Energy Company of the Year 2014", Tamar's AD division produces low carbon, baseload energy for thousands of homes. Our composting division recycles green and food waste into premium grade soil conditioner. ​

We currently have an award-winning network of 11 anaerobic digestion and composting sites around the UK. Each site is led by an operations manager and managed by a dedicated, highly trained team, supported by central function teams.

Established in 2011, Tamar is backed by a mix of influential shareholders including The Duchy of Cornwall, The Rothschild family, RIT Capital Partners plc, Fajr Capital and Sainsbury’s. 


We are proud to be supplying compost to such well-renowned sites as Kenilworth Castle and the Royal Festival Hall, as well as numerous homes, landscapers and farmers. Our anaerobic digestion division has been at the forefront of the UK’s AD sector since our inception. Read about our many ‘industry firsts’ on 'Our history' page and meet some of 'our team'
