New resalable aluminum bottle more eco friendly than glass
A team of scientists has made a new type of glass from opaque titanium and zirconium, which is harder, tougher and weighs less. A consumer packaging company has developed a lighter, resalable aluminum bottle that it hopes will replace glass bottles for many beverages, as it is more eco friendly.
According to a report in The Presidio Buzz, the new aluminum bottle has been developed by Rexam, which is one of the world’s largest consumer packaging companies.
Rexam uses a manufacturing process, DWI, or “drawn wall ironed,” which uses substantially less metal than impact extrusion, a more common method.
The company claims that the low weight of their bottle, 20 grams (.75 oz), compared to 180-200 grams for glass, markedly decreases its carbon footprint, in the form of lower manufacturing and distribution costs.
About 45 percent of aluminum cans are recycled, versus a mere 25 percent for glass bottles.
