Commingled collections reduce costs and increase the proportion of household waste recycled, according to a new report.
Researchers from WYG consultancy used information from WasteDataFlow, which is submitted to the Government by local authorities, to identify the key drivers to the top-performing councils for collecting dry recycling.
They found that 20 of the top 30 councils operate a fully commingled service. And while affluent areas tend to have higher yields of all materials, the analysis shows that fully commingled collections, including glass, outperform kerbside sorted collections by a similar margin across all levels of affluence.
Len Attrill, WYG project director, said: “As has been the case in the two previous years, the highest performing councils in terms of dry recycling are dominated by authorities that collect commingled dry recycling, with both recycling and residual waste collected fortnightly using wheeled bins.”
The researchers also found that no authority in the top 30 for kerbside sort recycling collected all materials separately.
