WRAP report on the fate of Clostridium botulinum in Anaerobic Digestion

Clostridium botulinum is a bacterium that is widely distributed in the environment, livestock manures and other organic materials.  Because Clostridium botulinum is encountered frequently, it might be present in organic materials such as food waste that are sent for processing at anaerobic digesters.

WRAP and Zero Waste Scotland have undertaken several research projects to understand the fate of Clostridium botulinum in AD.  A summary of this research can be downloaded from this webpage.  They found that the possible risks associated with Clostridium botulinum from the recycling of food-based digestate to agricultural land are similar to those for other organic materials that are frequently applied to farmed land, such as livestock manures.

For a copy of the full report, please contact William McManus at WRAP.
