We are pleased to announce the publication of the Research Hub report entitled 'Evaluation of the potential for improvement of the Residual Biogas Potential test and investigation of alternative test procedures for ‘End of Waste’ biofertilisers'

The report is the outcome of a project focused on the Residual Biogas Potential test, the only digestate stability test specified under PAS 110:2014. The project aimed to understand the cause of RBP test-related failures and invalid results, explore potential improvements to the method, and/or identify suitable alternatives.

A summary of the project scope, methods, and key takeaways from the report is available here.
