As far as can be seen from the Shropshire Star report referenced below, there was an explosion which resulted in a digester tank collapse and that led to the contents of the tank being dropped on the ground around the plant.
We found the short video below on YouTube, briefly showing the clean-up:
There was also previous spill at the plant last year, which appears to be beset by incident.
Thankfully, we don't think there were any injuries on either occasion, but there may have been some of the biomass which entered the local stream, again the articles referenced below don't make it clear just what the effect was on the local water quality. Hopefully, there would not be expected have been any significant loss of liquor outside of the bunded area for the plant, and therefore the clean up will adequately remove any future risk of pollution.

"The clean-up operation continues at the HarperAdams University anaerobic digestion plant today. The access road to the AD plant was fully cleared over the weekend. Digestate is now [contained]."
