Revealing the Lightest Glass Wine Bottle Globally: Portugal's Innovation
In a groundbreaking development, the world's lightest 750ml glass wine bottle, weighing just 260 grams, was unveiled at Expo 2025 in Osaka. This ultra-lightweight bottle, a collaborative effort by Vidrala and LiDA (Laboratory in Design and Arts at the Polytechnic of Leiria), sets a new standard for eco-efficient wine packaging while maintaining strength and versatility for various products.
This innovative bottle, which reduces the glass surface area by 20% due to its optimised geometry and ultra-thin walls, is made with up to 80% recycled glass. The development focused on material reduction, weight reduction, strength retention, and sustainability, achieving remarkable results in each category.
The development of this bottle is a testament to the significance of long-term partnerships between academia, industry, and society, which enabled innovation in glass design through shared knowledge and trust. The project is part of the "Packaging of the Future®" consortium, an initiative with a total investment of €104.1 million, composed of 79 entities from across the country, including companies, universities, research centers, associations, and the Leiria Region Business Association/Chamber of Commerce and Industry (NERLEI/CCI).
The "Packaging of the Future®" agenda aims to create more ecological, digital, and inclusive packaging solutions within the scope of the Recovery and Resilience Plan (RRP). NERLEI/CCI has planned institutional meetings in Japan to promote "Packaging of the Future®" and foster commercial relationships between Portuguese and Japanese companies.
Other recent industry innovations include Ardagh’s 300g lightweight bottle combining ultra-light design with durability and Margaret River Wine Association’s regional charter promoting bottles averaging less than 420g to reduce wine packaging emissions by over 20%.
At Expo 2025, several examples of the lightweight bottle with wine will be available, in partnership with Esporão. The bottle is not the only project being presented; "Living Surfaces" and "Sleeping Beauties" are also being showcased. "Living Surfaces" involves ceramic substrates that replicate rock formations for sea urchin habitats as part of a sea urchin population regeneration program. "Sleeping Beauties" involves functional 3D-printed models of historical scientific instruments from Portuguese museums for public engagement with scientific knowledge.
Vangest is leading the project in collaboration with NERLEI/CCI, Leiria Polytechnic, the Intermunicipal Community of the Leiria Region, and with the support of INOVA+. The presentation of these projects at Expo 2025 is in collaboration with other research centers, industry, and museums. This collaboration underscores the potential for sustainable innovation when academia, industry, and society work together towards a common goal.
- The groundbreaking development of the lightweight wine bottle, initiated by Vidrala and LiDA, is a significant example of how collaboration between academia, industry, and society can influence the manufacturing industry, specifically in the realm of finance and technology.
- The "Packaging of the Future®" consortium, a joint venture consisting of various entities including companies, universities, research centers, and associations, demonstrates the potential for finance and technology to foster innovation in business and industry, as seen in the ultra-lightweight wine bottle project.
