Doctor AD: Expert Advice for AD Plant Operators

13th December 2016

In response to industry feedback on the Biofertiliser Certification Scheme (BCS), which includes BSI PAS 110, WRAP developed a programme with Southampton University to provide independent technical advice for AD plant operators.

Key points
Can improve investigating an AD site’s operational procedures
Enables development of further understanding any existing monitoring for process optimisation
Assists AD operators in identifying any issues which could compromise digester efficiency and work with the plant operator to address these

Overview

Overview

In this study two AD facilities were visited by an AD technical expert. Plant operations were discussed and samples of digestate taken for further analysis at Southampton University’s laboratory, which included: 

  • physical and chemical parameters
  • residual biogas potential (RBP)
  • trace element analysis
  • trace element stimulation test

Both AD facilities were very positive about the impact of the exercise on their businesses and the improvement in efficiency that independent technical advice delivered. Further detailed information on the findings from one of the sites visited can be found in the adjacent technical report.
