The CO2 production process
Digesting
Anaerobic digestion is the process driving the biogas plant. This is where bacteria break down organic plant matter without the presence of oxygen inside our biodigesters.
We only feed arable crops into our digesters. This means our outputs are 100% waste free.
Separating
Apsley Farms’ high-tech approach uses pressure to separate our CO2 from biomethane (renewable natural gas)
Distributing
Since 2016 we have produced nearly 40,000 tonnes of food-grade liquid CO2. As of July 2022 we are selling directly to industries.
With an on-site automated laboratory we test every batch to keep standards consistently high.
There is storage for 150 tonnes of CO2 on-site at Apsley Farms.

How to buy sustainable CO2 for your business
Our CO2 output
All of the energy needed for the manufacture of CO2 is supplied by our own biodigestion process. This means that we are unaffected by fluctuations in energy prices and were able to keep supplying the UK during the commercial CO2 shortages in 2021.
Currently, our daily production is around 32 tons of CO2. With a purity of 99.99%, this is suitable for any use within the food industry.
