ALTEMIRA Co., Ltd. (Head Office: Bunkyo-ku, Tokyo; hereinafter “ALTEMIRA”), part of the ALTEMIRA Group, and MA Aluminum Corporation (Head Office: Susono City, Shizuoka Prefecture; hereinafter “MA Aluminum”) have commenced the continuous supply of aluminum bottles and caps made from 100% recycled materials, aiming to realize a recycling-oriented society.

Since December 2022, ALTEMIRA and MA Aluminum have been manufacturing 410ml aluminum bottles using 100% recycled material (*1), progressing the switch to products that reduce CO2 emissions by approximately 25% compared to conventional aluminum bottles. This time, by using 100% recycled material not only for the aluminum bottles but also for the caps, CO2 emissions per can have been reduced by approximately 37%, enabling the provision of containers with a lower environmental impact.

Caps require high performance, such as sealing integrity, which traditionally necessitated high-strength materials containing significant amounts of virgin metal. Manufacturing caps from recycled material requires handling materials with properties unique to recycled content, rather than those used for conventional caps. To meet the same performance requirements as before, we approached the challenge from both material development and cap manufacturing perspectives. This has established a system enabling the continuous supply of aluminum bottles and caps made from used beverage cans (UBC).
