3.2 Table 1 below shows the changes in key household waste streams observed between 15-16 and Section 5 onwards focuses on key elements of this. The data is combined for all PI authorities. Table 1: Summary tonnage and NI data for PI, 2015-2018 3.3 PI partners will have been aware that since 2011-12, recycling rates have plateaued or reduced, but there has been a slight increase in recycling rates since 2015-16, although the 17-18 figure in total recycled tonnages is slightly down on 16-17. 3.4 The latest full-year data available for the UK applies to 2016 (calendar year) when the UK saw a very slight increase in recycling rate from 44.2% in 2015 to 44.6%. This continues the national trend of a stagnant recycling rate. 3.5 Another key measure of performance for PI partners is contamination of DMR. This, and other measures, are calculated through a sampling programme at the Materials Analysis Facility (MAF), set up by Project Integra in March 2006 and located within the grounds of the Alton Materials Recovery Facility (MRF). The findings of this analysis influence interpretation of changes in recycling rate and other measures, so is dealt with first in this report. 4 MAF Analysis 4.1 Contamination
