UK: Plans by Knauf Insulation and Veolia to tackle complains about the ‘offensive’ odour from a glass-recycling unit at Knauf’s St Helens mineral wool plant have been approved by the local council. The proposals include introducing a wet scrubber and extending the current dryerstack to 30m from 13m, according to the St Helens Star newspaper. These measures were suggested following an assessment with Odournet. Local residents have made complaints about the Veolia-run unit since it became operation in October 2017.
