AD transforms animal by-products into nutrient-rich digestate
AD transforms animal by-products into nutrient-rich digestate

1. Decarbonises the food system

  • Decarbonises farming by cutting emissions from animal waste and reducing dependence on energy/fuels from non-renewable sources, and artificial fertiliser (one tonne of chemical fertiliser replaced by 1t of natural fertiliser saves 1t of oil, 108t of water and between 5-9t of CO2-equivalent).
  • Reduces methane emissions from food waste, which would otherwise go to landfill.
  • Biofuel in transport/farm machinery, reduces particulate matter and improves air quality.

2. Better waste management equates to improved soils

  • Transforms farm material (slurries, crops, chicken litter, vegetable off-cuts, out-grade crops or animal by-products) and inedible food waste into nutrient- rich digestate, which can be used in place of artificial fertilisers.
  • This improves soil organic matter, maintains pH levels and increases fertility, while cutting costs for farmers.

3. National energy security

  • Imports of liquefied natural gas from unstable regions of the world, such as Qatar and Algeria, make up 30% of UK gas imports; AD can help redress this.
  • If all suitable UK feedstock was used to produce biogas through AD, displacing natural gas, the UK’s gas imports would fall by 16%.

4. Green jobs

  • AD could employ 35,000 people across construction, manufacturing, plant operation and export industries if it reached its full potential in the UK. It already supports about 4,000 jobs.
