The results of a life cycle assessment study on aluminium closures for wine bottles show how the closure can reduce the ecological footprint of the bottles. Overall, the aluminium screw cap only accounts for 2 percent of the climate impact of a bottle of wine.\u00a0<\/strong><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The assessment, which is based on the PEF (Product Environmental Footprint), was carried out by Quantis in 2022 on behalf of the Aluminium Closures Group (ACG). The study shows that the aluminium screw cap only accounts for 2 percent of the climate impact of a bottle of wine, and investigates beyond that, how this impact can be further reduced<\/strong>.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

It is generally recognised that the recycling of aluminium after its use has a positive impact on the environmental balance of the closure, as bonus points are included in the calculation of the environmental balance for the avoided production of primary metal. For the Recycling aluminium requires around 95 per cent less energy than primary production.<\/strong> needed. The study shows that although current recycling rates in Europe are already contributing to a lower environmental footprint, there is still room for improvement. Room for further improvements<\/strong>.<\/p>

If the recycling rate for aluminium screw caps were increased from the current 69 per cent (according to the Product Environmental Footprint Category Rules (PEFCR) for wine) to 100 per cent, the recycling rate would be 100 per cent.The climate impact of a bottle of wine is reduced by 18 per cent and that of the entire bottle by 0.4 per cent<\/strong>. In this context, it should be noted that aluminium screw caps can be easily sorted and recycled, regardless of whether they are collected together with glass or other lightweight aluminium packaging.<\/p><\/div><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\u201eSmall things can make a big difference. At ACG, we remain committed to making a positive contribution to mitigating climate change. Although the aluminium screw cap does not make a significant contribution to the footprint of a wine bottle, the study has explored ways in which the environmental impact of the closure can be further reduced.\u201c<\/p>

Another parameter that was examined as part of the assessment is the weight of aluminium screw caps. If the amount of aluminium used in the closure is reduced by 15 percent (from 4.2 to 3.6 grams), the climate impact is reduced by 14 percent. The climate impact of the entire wine bottle is reduced accordingly by 0.3 per cent.<\/p>
