Countries implementing deposit-return schemes (DRS) for drinks containers typically halve the volume of litter from these items, according to research.
A major study by circular-economy body Reloop found that rewarding customers for bringing back empty beverage cans and bottles led on average to a higher-than 50 per cent cut in the amount that were incorrectly disposed of.
In some cases the impacts were higher. Western Australia saw an 89 per cent reduction, Estonia 88 per cent and Oregon in the US 81 per cent.
Across all geographies, litter from plastic bottles typically fell by 63 per cent when deposits were introduced, while the volume of plastic bottles and metal cans discarded dropped by about four-tenths.
“DRS stands out as the single most effective tool for reducing beverage container litter,” said the study.
“No other approach has demonstrated similar results, and few enjoy the same level of
public and political support.
“With rising concern about plastic pollution and increased demand for policy solutions
that deliver measurable results, DRS offers a proven pathway forward.”
A row broke out between charities and shops earlier this year over the UK’s controversial plans for a DRS.
