Your next partner
in circular energy

For more than 40 years, we’ve derived green energy from organic waste streams – advancing the future of circular energy.

Our cases
Employees on biogas plant

We develop, construct, operate and own end-to-end biogas systems. We work across every step — from biomass sourcing and waste management to the delivery of biogas, biogenic CO2 and nutrient-rich biofertiliser. 

Selected case studies

All cases

Science has to meet practice

For more than four decades, we’ve refined our modular approach to Biogas technology. Now, both our plants and the entire biogas process are proven by science and practice by a multitude of clients — worldwide. That’s your guarantee for a modern, solid and profitable solution.

Biomass and biowaste should be handled responsibly

Sustainable Sourcing

We are strictly committed to sourcing only animal or organic waste, ensuring a positive impact on our environment.

Local Procurement

Our biomass primarily comprises animal manure and organic waste from feed and food processing — and industrial byproducts from nearby industry. We prioritize local sourcing, reducing transportation emissions and fostering community partnerships.

Responsible Practices

We steer clear of raw materials in biogas plants that could have been used as feed or food, ensuring ethical energy production.

We see energy in waste

Potential and possibility can be found in everything — when coupled with the right mindset and a committed skillset. While some may view waste as mere discard, we envision it as a source of energy, untapped potential and ultimately, an opportunity for creating value – benefiting both people and planet.
