British Glass has raised serious concerns that the UK Government’s Deposit Return Scheme proposals will have a detrimental impact on closed loop glass recycling.
British Glass responded to the UK Government’s consultation which closed last week (Friday 4 June) raising fears that the proposed Deposit Return Scheme (DRS) will have a detrimental impact on closed loop glass recycling, increase carbon emissions and incentivise an increase in plastic consumption at the expense of glass.
In addition, a new report published this week by circular economy experts Oakdene Hollins has found that it will cost almost three times as much to recycle glass through a DRS compared to alternative kerbside recycling, favoured by the public.
In its consultation response, British Glass explained that the industry is committed to a 90% collected for recycling rate and for the first time announced a commitment to an 80% remelt target by 2030 which would see 80% of all glass recycled back into new bottles and jars as part of a closed loop.
A major concern for those working towards these targets is the fact that the government proposals do not include a recycling or remelt target as part of the deposit return scheme.
Without these targets in place the glass sector is concerned that glass collected through a deposit return scheme will be collected for use in aggregates (such as construction) rather than for high value closed loop recycling into bottles and jars.
Adding to concerns is the government’s proposal that glass collected through the DRS via reverse vending machines will ‘compact glass into four, five or six pieces’.
British Glass believe it is impossible to control the number of particles glass can be broken into and have set out to illustrate this through an exercise in breaking a variety of glass bottle formats.
To be able to recycle glass as part of a closed loop, the material must be able to be colour sorted into green, amber, and clear colours, however, breaking glass as part of the deposit return scheme will drastically reduce the quality and quantity of glass available for bottle-to-bottle recycling.
The recent Environmental Audit Committee (EAC) inquiry into DRS recognised the challenges associated with glass in the DRS including the risk to closed loop recycling of glass if the material is crushed within the scheme.
On material switching, British Glass have highlighted international evidence suggesting that including glass bottles in such a DRS incentivises the use of plastic packaging, leading to an increase in the amount of plastics on the market – the very thing we want to avoid.
At the same time, countries such as Wales, Norway and Sweden have shown it is possible to achieve a circa 90% glass collected for recycling rate through dedicated household and bottle bank collections underpinned by consistent collections that are well communicated to the public.
Phil Fenton, Lead Packaging and Recycling Adviser, commented: “We all know more needs to be done to increase recycling and move towards a circular economy for all packaging formats.
“Recycling a tonne of glass into new bottles and jars saves 580kg of co2 emissions – saving over 594,000 tonnes of CO2 in 2019.
Alternatively, if recycled glass is used as aggregates, it actually produces more carbon. This is why we are so concerned that a DRS that crushes or compacts glass with no recycling target will be detrimental to bottle-to-bottle recycling and to the environment.”
On the Oakdene Hollins report, he added: “This new report highlights the incredible cost of recycling glass through a deposit return scheme compared to keeping glass at our kerbside.
“It will cost £632 a tonne to recycle glass through a DRS compared to £218 by keeping glass at our doorstep.”
