Through our sustainable practices and forward-thinking designs, we pave the way for a cleaner, greener future powered by biogas.


Drawing on years of industry experience, our engineering team delivers unparalleled anaerobic digestion solutions for maximum efficiency and optimal performance.


Our R&D team is at the forefront of innovation, driving the evolution of AD design, exploring groundbreaking technologies and processes that will shape the future of anaerobic digestion.

Closed Loop System

Municipalities and farms send their organic waste to our digesters, producing biogas which can be converted to electricity, or upgraded to renewable natural gas (RNG) and digestate. Digestate is rich in nutrients and can be returned to the fields to nourish crops, which ultimately sustains local communities and livestock. This closed loop cycle maximizes resource efficiency, reduces waste, generates clean energy, and supports the interconnectedness of communities, farms, and the environment.
