Development of Next-Generation Eco-Friendly Can Lid "EcoEndTM"
with Major Revisions to Materials and Manufacturing Methods– Joint efforts by Toyo Seikan and UACJ reducegreenhouse gas emissions by 40% –Toyo Seikan Co., Ltd. ("Toyo Seikan"), a consolidated subsidiary of Toyo Seikan Group Holdings Ltd.,
has jointly developed with UACJ Corporation ("UACJ") a beverage can lid "EcoEnd" that reduces
greenhouse gas ("GHG") emissions by approximately 40% by significantly increasing the use ofrecycled materials that have a GHG emission level approximately 3% of that of new aluminum.
Compared to current beverage can lids, the use of EcoEnd will reduce GHG emissions byapproximately 13,000 tons*1 per billion lids. If all beverage can lids sold by Toyo Seikan in Japan are
replaced with EcoEnd, a GHG emission reduction of approximately 140,000 tons*2 is expected annually.
Current beverage can lids require a substantial quantity of new aluminum to ensure the necessarylevel of quality in terms of material workability and strength. By combining UACJ's material
manufacturing technology and Toyo Seikan's lid-forming technology, we have realized thedevelopment of a next-generation lid with the same quality performance as the current lid even when
the use of new aluminum is reduced. Since the thickness of the lid is maintained, there is no need tochange the equipment for beverage manufacturers that attaches the lid after the beverage is filled.

With the development of EcoEnd, it is expected that more recycled materials, such as used beveragecans (UBC), will be incorporated in future production, leading to a reduction in GHG emissions due toa decrease in the use of new metals. The following images illustrate the new aluminum material

New Recycling Flow Proposed by EcoEnd

Toyo Seikan Group Holdings and UACJ signed a business alliance agreement on February 6, 2023,
with the goal of further promoting the horizontal recycling of aluminum cans; the development ofEcoEnd is part of this alliance. Together, we will continue to advocate for the horizontal recycling ofaluminum cans and the reduction of GHG emissions throughout the beverage container supply chain.
