Successful Material Change for Anaerobic Digestion and Composting Facilities

by Mark Clayton

Aardvark EM Limited were part of the advisory team to Foresight Group on the successful acquisition of the Material Change portfolio which comprises of anaerobic digestion (AD) and composting facilities. Aardvark?s role was to provide assessments of feedstock supplies of both purpose grown crops and wastes for two AD plants: one generating 2.8 MW of electricity and one providing 430 m3/hr of biomethane into the gas network. In addition, Aardvark assessed digestate management options and the requirements regarding storage, spreading and nutrient recovery from this product.

 Aardvark EM Ltd is a specialist supplier of services and solutions to the AD and organic waste sector, which include:

  • Plant optimisation - enhancing the performance of operation of plants
  • Feedstock valuations ? using its tool Feedsum to compare feedstock values against their actual gas production and hence worth
  • Digestate management using Landspread -  Aardvark?s proprietary tool developed specifically to determine storage requirements, number of spreading days and nutrient recovery across the UK.
  • Plant recovery; stepping in to provide WAMITAB qualified technical support for poorly performing plants

Aardvark has an experienced technical team that has had significant involvement in over 30 AD schemes in the UK and 8 internationally. The company has also run its own small-scale AD system since 2012 at its base in Somerset and so has the hands-on practical experience to understand technical, operational and biological requirements for running fully commercially fundable AD operations.
