WRAP’s latest report under the MRF sampling regime has revealed a 1.2% increase in material contamination in England, while Wales maintains lower levels.
For the fourth quarter of 2016, 14.1% of material was rejected by MRFs in England compared with 12.9% in the previous quarter.
It is the highest level of contamination seen in England since Q4 2015.
Wales, on the other hand, improved its rate from 11.1% to 10.3% between Q3 and Q4 2014.
The quality of plastic produced by MRFs in England has been “gradually reducing” since Q1 2016, according to the WRAP report. Glass quality has been gradually increasing since Q4 2015.
MRFs in England dealt with 3.8% more material in Q4 2014 compared with the previous quarter – an increase of 32,000 tonnes to more than 884,400 tonnes.
Steve Lee, director general of Resources & Waste UK, said the results were “more tough news for English recycling”.
The sampling frequency to test material was increased in October 2016.
