The Waste & Resources Action Programme is working with supermarket Sainsburys in a trial to collect mixed glass and turn it into a range of containers without colour sorting it.
The trial is part of WRAPs GlassRite Wine initiative which aims to encourage the use of lighter weight glass wine bottles in the UK and to drive the increase of recycled glass content.
WRAP manufacturing project manager Tammy Strickland told MRW: Many councils collect mixed glass, which can sometimes be difficult to sort. A lot of this mixed glass is going into the secondary market like aggregate, for example. But we are working with Sainsburys to see if we can use mixed glass without colour sorting it. We will take the mixed glass and remelt it to produce another glass range of containers for various products. This could be anything from mayonnaise bottles, to wine bottles, to jam bottles.
The mixed glass has a different tint [light green] to other recycled glass. We will see what consumers think of this and see whether there is sufficient demand for the product.
Strickland also explained that the wine industry was still a traditional industry and there sometimes can be strict colour perimeters as to what is used in their products. The results of the Sainburys trial will come out in the summer.
