Climate change is at the heart of global conversations this week, as world leaders gather in Sharm El-Sheikh for COP27. All parties involved have made environmental pledges, with the UK committed to decarbonising all sectors of the economy and meeting a target of Net Zero emissions by 2050.

Anaerobic digestion (AD) has a key part to play in helping to deliver these targets, through the production of renewable energy and the drive towards decarbonising agriculture. Both the energy supply and agriculture sectors are significant contributors to the UK’s carbon footprint. The energy supply sector was responsible for approximately 21% of all UK greenhouse gas emissions (GHG) in 2020, while the agriculture sector produced 11% of emissions.

Reducing reliance on fossil fuels

Phasing out fossil fuels in favour of renewable energy sources is high on the international Net Zero agenda. A recent survey found that 68% of people want to see an increase in government investment in renewable energy.

AD reduces reliance on fossil fuels by generating green energy from organic waste and sustainably grown crops. For example, our Condate Biogas plant supplies almost 100% of the gas needs for the nearby town of South Molton, as well as generating enough electricity to power over 900 homes.

Decarbonising agriculture

Alongside producing green energy, the by-product of AD (known as digestate) makes a high quality natural fertiliser. Within our circular economy, farmers who supply crops to our AD plants receive digestate in return, which they use as a replacement for expensive and environmentally damaging artificial fertilisers.

Artificial fertiliser accounts for over 10% of agricultural greenhouse gas emissions, so switching to natural fertilisers such as digestate is a major step in decarbonising the sector.

Recognising AD’s potential

We’re not alone in calling for greater recognition of AD’s value. The Anaerobic Digestion and Bioresources Association (ADBA) has responded to the UK government’s Net Zero strategy by stating that ‘the value of biogas in the decarbonisation mix is underestimated’.

AD technology currently reduces the UK’s greenhouse gas emissions by 1% annually. With the industry fully deployed, this could rise to a 6% reduction of the UK’s total GHG emissions by 2030.

At Ixora Energy, we are motivated to continue helping the UK reach its Net Zero targets. From promoting biodiversity to sustainable shrimp farming, we constantly innovate and collaborate, finding new ways to maximise the potential of AD.
