Diageo has collaborated in a successful pilot project to create the first low carbon footprint glass bottles produced by a Scotch whisky brand.
It is working with glass manufacturer Encirc and industry research and technology body Glass Futures to use biofuel-powered furnaces to reduce the carbon footprint of the bottle-making process by up to 90%.
The group used its Black & White Scotch brand for the trial, producing 173,000 bottles.
Further work now needs to be carried out to develop and scale the trial for future production, but Diageo said it represents a step forward in the drive towards and sustainable grain-to-glass supply chain.
Diageo has supported Glass Futures from concept and following the the trial has agreed a 10-year partnership to accelerate collaboration and innovation in the glass industry.
John Aird, senior packaging technologist at Diageo, said: “This trial is just a first step in the journey to decarbonise this aspect of our supply chain, and we still have a long way to go, but we are delighted with the results of the collaboration and the platform it creates for future innovation.”
Adrian Curry, managing director at Encirc, said: “We have set the standard globally with this trial and now the glass industry needs to work towards realising what we’ve proved is possible – we now know that glass can be the most sustainable of all packaging types and must all work together to ensure that happens.”
The project is part of the UK Government Department for Business, Energy and Industrial Strategy’s Energy Innovation Programme.
Glass Futures is leading a £7.1m initiative to explore the most effective routes to switching glass manufacturing to low carbon fuels.
