About Duranta
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.

As the company grows, Duranta continues to expand its operations and optimise how renewable energy and recovered materials reach the market.
