A greener, renewable future with Bio-CO2
Our CO2... Reliable. Renewable. Never from waste.
Pretoria Energy is redefining CO2 supply in the UK through renewable production, total supply-chain control, and complete operational independence.
As the UK’s largest anaerobic digestion (AD) operation, we deliver biogenic CO2 with unmatched reliability, traceability, and environmental integrity – even in volatile markets.
We don’t simply produce Food Grade CO2, we cultivate it.
A renewable revolution in CO2 supply
Our biogenic CO2 is produced entirely from renewable biological sources – never fossil fuels.
Operating within the short-term carbon cycle, it provides a genuinely low-carbon, circular alternative for organisations committed to decarbonisation without compromising performance or supply security.
Why Biogenic CO2?
- Derived from crops and agricultural by-products
- Naturally reabsorbed within the short-term carbon cycle
- No long-term fossil carbon footprint
- Designed around circular economy principles
- Supports net-zero and ESG objectives
Biogenic CO2 offers a future-proof alternative for businesses serious about sustainability.
100% in-house. 100% controlled.
From crop cultivation to final delivery, we control every stage of production.
This fully integrated model ensures:
- Consistent product quality
- Secure, year-round supply
- Complete traceability
- Market resilience
We are one of the few UK producers operating a truly end-to-end CO2 supply chain — fully owned and managed in-house.
Our integrated operation includes:
- Over 10,000 hectares of self-farmed crops
- Anaerobic digestion plants powered by our own renewable feedstocks
- Straw pre-treatment using recovered process heat
- In-house logistics and distribution
This level of control guarantees transparency, resilience, and long-term reliability – even during market disruption.
