A survey has been carried out for WRAP and Sainsbury’s by Glass Technology Services among 79 men and women across a range of ages to establish whether consumers would accept packaging with a slightly green hue in place of a clear glass one.
The objective is to increase the uptake of mixed recycled glass, which is becoming more prevalent through commingled collections.
The research showed that, in most cases, using a container with 90% mixed-colour content would not, did not, have a detrimental effect on the purchase decision. Whilst this is a welcome addition to the work that is taking place to find a more sustainable application for glass that is collected through commingled channels – much of which currently goes to road aggregate – there is obviously much discussion that still has to take place throughout the supply chain.
“Although we can colour separate good quality mixed glass collections from bottle banks and kerbside at our cullet treatment plants, we would draw particular attention to the likelihood of more pressure on the waste industry to reduce carbon, and that would require a return to colour separation within bottle banks or kerbside collection,” says Berryman’s general manager, Mick Keogh.
