Industry questions value of bottle recycling scheme

10th November 2019 | Recycling

Glass bottles should not be included in the new cashback recycling scheme being introduced in Scotland and across the UK, waste and drinks industry experts have said. Potential carbon savings from including glass have been overstated, they claim, and the move could even prove more damaging to the environment than continuing with existing methods.

The findings come from a new report compiled by trade body British Glass, which proposes an alternative “polluter pays” recycling scheme for glass packaging that would be funded by producers rather than consumers. “We support a scheme that significantly increases recycling and the reuse of resource, but under the existing plans, which include glass, this is not the case,” said Dave Dalton, chief executive of British Glass.

He says there is “compelling evidence” from overseas that shows including glass in a deposit-return system (DRS) can lead to unintended environmental and social consequences. These include brands switching to plastic packaging to avoid higher costs associated with collecting and recycling glass – a situation that has led some countries to scrap plans for such schemes.

Scotland’s DRS is being designed by state-funded delivery body Zero Waste Scotland (ZWS), and is due to be rolled out in 2021. Research suggests such a scheme – where a fee is paid shoppers when purchasing an item, then refunded when the container is brought back – could stop 18 million cans and 21 million bottles from ending up in landfill or as litter in Scotland each year.

The plan is for an “all-in” model that will include all PET plastic drinks bottles, aluminium and steel cans and glass bottles, with a deposit level set at 20p. Jill Farrell, chief operating officer for ZWS, said, “The decision to include glass in Scotland’s deposit-return scheme will maximise benefits for the planet and consumers. Including glass significantly increases the scheme’s carbon savings. Including glass also allows us to maximise the wider benefits of the scheme, not least by helping to reduce the amount of litter.”
