Case Study 3 - Heat from UK Agricultural & Food Wastes

This bioenergy GHG calculator tool presents LCA analyses results for different scenarios where heat bioenergy is generated from biogas, produced through the anaerobic digestion of UK agricultural and food wastes.

  • Bioenergy heat GHG intensities are compared to the UK’s sustainability standard for bioheat and the equivalent GHG intensity of heat generated by natural gas
  • Where high emission processes are mitigated such as certain slurry storage and land spreading activities, there is potential for preventing large agricultural sector emissions if these wastes are instead used within anaerobic digestion systems
  • Use of anaerobic digestion waste (digestate) material as a fertiliser can replace the need for supplementary fertilisers.
