News Release (July 9, 2024)
Completion of the mass production system for "EcoEndTM,"
the Next-Generation Beverage Can Lid, Which Achieves a 40%
Reduction in Greenhouse Gas Emissions- A Collaborative Effort by UACJ and Toyo Seikan Toyo Seikan Co., Ltd. ("Toyo Seikan"), a consolidated subsidiary of Toyo Seikan Group Holdings, Ltd.,
has completed the establishment of the production system for EcoEnd, a beverage can lid that reduces
greenhouse gas (GHG) emissions by approximately 40% compared to current products, developed
jointly with UACJ Corporation ("UACJ").*1 This includes the establishment of a lid material production
system and the procurement of recycling materials by UACJ, as well as the preparation of lid
manufacturing equipment at the Toyo Seikan Ishioka Factory. We will now proceed with preparations
for mass production to meet the needs of our customers.

<EcoEnd's Features>① Significant reduction in GHG emissions
By significantly increasing the use of recycled materials, which have a GHG emission of
approximately 3% compared to primary aluminum, we have achieved a substantial reduction inGHG emissions during the production of raw materials. Compared to current beverage can lids,EcoEnd reduces GHG emissions by approximately 13,000 tons per billion lids.*2 If all beverage canlids sold by Toyo Seikan in Japan are replaced with EcoEnd, an estimated annual reduction of
approximately 140,000 tons can be achieved.*3

② Proposal for a new aluminum recycling flow with the increased use of recycled materials
Because the strength and other characteristics required for the lid and the body of the can aredifferent, a certain amount of primary aluminum needs to be used for the lid, and the compositionneeds to be adjusted. The material in the EcoEnd reduces the use of primary aluminum andincreases the proportion of recycled materials, such as used beverage cans (UBC), so that itmatches the composition of the can body more closely. Therefore, at the point of melting, thematerial of the EcoEnd and the can body can be considered the same mono-material. After it melts,
the composition can be adjusted, and the characteristics of the lid and the can body can bedifferentiated. The development of the EcoEnd has made it possible to circulate a large amount ofrecycled materials in the lid, which was previously challenging, through postmelting composition
adjustment and manufacturing techniques. In the future, more recycled materials will be used in
the lid, leading to a reduction in GHG emissions due to the decrease in primary aluminum usage.
The new aluminum material circulation flow realized by EcoEnd is as follows:
Current Aluminum Container Material Recycling Flow

New Recycling Flow Proposed by EcoEnd③ No need to change filling line equipment due to consistent lid thickness
When the same material as that used in the can body is used for the lids, it is generally necessary
to increase the lid's thickness to compensate for the lack of strength due to the increased amountof recycled material.
By combining the material manufacturing technology by UACJ and the lid forming technology by
Toyo Seikan, EcoEnd has achieved the same quality performance as the current lids, even withincreased use of recycled materials. Because there is no change in the thickness of the lid,*4 there
is no need to change the equipment that attaches the lid after beverage filling, allowing for smooth
replacement.
Our company and UACJ signed a business partnership agreement on February 6, 2023, aiming tofurther promote aluminum can horizontal recycling. The development of EcoEnd is also part of thispartnership. Going forward, we will continue to strive for further promotion of aluminum can horizontal
recycling and the reduction of greenhouse gas emissions throughout the entire supply chain throughthis business partnership.
