Pyrolysis
Our Green Energy Hubs produce large amounts of excess heat which can be delivered as a fully sustainable, carbon negative energy source for your business.
Carbon removal
Pyrolysis is the only practical and available carbon removal technology available today, and is a critical tool for the world's journey to Net Zero.
Biochar
Biochar is a long-term store of carbon, and an effective soil additive improving plant yields and health. We are committed to producing it on a large scale to make a real difference in the fight against climate change.
