Details

The Environmental Permitting Regulations (EPR) 2010 provide two exemptions for the anaerobic digestion of waste up to specific capacity limits.

There is currently no provision within these exemptions to allow the use of auxiliary (back up) flares to dispose of the biogas should the appliances burning biogas break down or undergo routine maintenance.

In these circumstances, you will not need an environmental permit if you follow the requirements in this guidance.
