Adnams, an award-winning brewer, retailer and distiller based in Southwold on the Suffolk Coast of the UK, has long been a leader in sustainable beer production.
Having already pioneered the use of lightweight branded glass for their products in 2007, Adnams wanted to see how far they could push their bottle as a key component as their overall carbon footprint, while retaining the distinctive shape and height the brand was known for.
O-I’s designers and manufacturing team pushed the boundaries of glass production to offer an embossed branded bottle at 280g, shaving 19g off the brand’s already market-leading bottle. The distinctive shape and height of the bottles remained intact, meaning there would be no impact on the filling equipment, tertiary packaging or brand image.
Adnams is now the UK’s lightest branded 500ml glass premium ale bottle, which sets a new benchmark for all brewers. This has created an additional carbon saving of 100 tonnes and removed 115 tonnes from the glass waste stream.
Constant environmental improvement is part of the DNA at Adnams. We wanted to see how far we could push our bottle as it is a key component of our overall carbon footprint. We had done it before and knew O-I. They are very forward thinking and share our ethos, so it was logical to work together.
