The CO2 production process

Growing

Our crops absorb CO2 from the atmosphere using photosynthesis to grow.

Keeping circular agriculture in mind, we also spread our solid and liquid digestate as a sustainable fertiliser to create higher yields.

Farming

We use modern farming techniques and equipment to maximise efficiency while harvesting our crops, ready to feed into our biodigesters.

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.

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.
