How Duranta is turning waste into power – and building a fairer energy future

Tucked away in Teesside, there’s a different kind of energy revolution taking place. It’s not driven by wind or sun, but by something the modern world has in abundance: waste.

Duranta Energy runs one of the region’s leading anaerobic digestion (AD) facilities, where waste is transformed into clean electricity, biomethane, and low-carbon heat. Every year, the site processes up to 120,000 tonnes of waste, helping to reduce landfill, lower emissions, and create renewable energy from materials that would otherwise be lost.

A growing need for change

Since opening in 2012, Duranta has become a cornerstone of the Teesside energy ecosystem. The facility provides flexible, low-carbon energy to the local grid and gas network. But as the plant scaled up and generation volumes increased, they needed an energy partner that would allow them to have more control over how their power reached the market and who profited from it.

Rewiring the model with tem

In 2024, Duranta made the switch to tem, joining a growing network of UK-based renewable generators selling their energy directly through RED™, a transparent energy platform that connects them with thousands of businesses looking to buy renewable energy across the UK.

Unlike traditional wholesale market routes, RED™ removes the middlemen from the transaction, cutting out hidden fees that eat into a generator's bottom line. That means more revenue, more flexibility, and more of the value flowing back to Duranta and the people working hard to produce clean energy.

Waste into energy, energy into impact

Duranta’s work shows how waste can be part of a bigger, more sustainable cycle. They collect food and organic waste from local supermarkets, food producers, and councils, then turn it into clean energy and natural fertiliser that goes back into the soil.

Now, by selling their power through tem, that cycle goes even further. Instead of profits being lost in the system, more of the money from their clean energy stays with them, helping to fund new generation technologies, cut more carbon, and do more of what they do.

Leading from the ground up

Duranta is helping shape the future of energy, and its impact is hard to ignore. As the UK transitions to a low-carbon future, AD plants like theirs will be key to delivering reliable, renewable power at scale.

But their role goes beyond generation. It’s also about how that energy is sold, who benefits, and the fairer, more transparent system they’re helping to build.
