German water bottle company air up has partnered with speciality material company Eastman to create a new line of reusable bottles.

Intended for the European market, the new bottle range is made with Eastman's Tritan Renew material, which has 50% certified recycled content via Eastman’s molecular recycling technology.

This technology breaks down hard-to-recycle plastics into their molecular building blocks to allow them to be reused for manufacturing new polymers.

air up’s new Generation 2 bottles containing Tritan Renew are the result of this partnership and are available in two sizes, 600ml and one litre.

The lightweight and durable bottles are developed at production facilities within the EU.

According to Eastman, these facilities are powered by 100% renewable energy and use up to 88% less plastic when compared with single-use plastic bottle plants.

air up co-founder and chief 'evangelist' Lena Jüngst said: "We believe it's time to think new when it comes to product development, recognising that addressing climate change requires more than simply urging immediate behaviour change.

“Our approach is to create high-quality products that not only appeal to consumers but also lead to an impact on society and the environment. Our new bottles made with Tritan Renew are a powerful example of how we are actively working to create change together with Eastman, a leader in circular materials innovation.”

Last month, Eastman teamed up with cosmetic packaging solutions supplier ICONS|ICS to launch a new monomaterial cosmetic compact product.

The container is made of Eastman Cristal One Renew, an RIC1 resin with 100% certified recycled content.
