Toward a Zero-Waste Society


Basic Perspective
Toyo Seikan Group's business involves processing raw materials, such as metals and petroleum, to manufacture packaging containers and steel plates. Therefore, effectively utilizing resources, including reducing input materials and minimizing waste generation through recycling, is a significant mission for the group. In particular, packaging container waste accounts for 63.6% of household waste by volume, according to the composition survey conducted by the Ministry of the Environment in 2023.
Under the "Eco Action Plan 2030," we have set a goal to reduce the use of finite resources by 30% and are actively working towards achieving a resource-circulating society. In addition to the ongoing efforts to lightweight containers, we are also actively promoting the use of recycled materials. Improving the usage rate of recycled materials in metal cans and increasing the use of recycled materials and plant-derived resins in plastic containers contribute not only to the goals of the "Eco Action Plan 2030" but also to solving societal issues. These activities are not only important for the effective utilization of resources but also contribute to energy reduction during material manufacturing, making them crucial in terms of addressing global warming. We are also working on creating mechanisms to promote product design and development suitable for sorting and facilitate the collection of used containers, contributing to the realization of a circular economy.

Sustainable Packaging
Packaging play a crucial role in protecting and facilitating the transportation and storage of products. They also provide information to consumers and stimulate their purchasing desires. However, traditional packaging have largely been disposable, placing a significant burden on the environment. It is now important to reduce the environmental impact of packaging. Achieving sustainable packaging requires the use of renewable materials, promoting recycling, and lightweighting, among other measures. Additionally, it is essential for companies and consumers to collaborate in making environmentally conscious choices. To preserve the Earth's environment while sustaining economic activities, our group is committed to developing sustainable packaging.
Reduce: Activities to Lightweight Packaging
Tokyo Seikan Group has been working on lightweighting packaging to reduce the amount of materials used. By lightweighting packaging, we can reduce the use of depleted resources such as iron and aluminum, which are materials for metal cans, and petroleum, which is a material for PET bottles. Our group packaging to make efforts to effectively utilize limited resources while maintaining and improving the usability and quality of packaging to protect their contents.
Beverage Steel Cans and Aluminum Cans
The weight of beverage steel cans and aluminum cans has been reduced by using thinner steel sheets and aluminum plates, and the weight reduction rate in the 2023 fiscal year is approximately -16% for steel cans compared to the 2004 fiscal year, and approximately -6% for aluminum cans.

Activities for FY2024
"Zero Waste Fest 2024" Opening Event Held on May 3rd (Waste Day)
In collaboration with "Takizawa Garbage Club," led by comedian and garbage collector Machine Guns Takizawa, Toyo Seikan Group held a public opening event at our company (Osaki Forest Building) on May 3, 2024 (Fri, holiday), which marked the first day of "Zero Waste Fest 2024."
The theme for this year was "Waste x Art," aiming not only to promote SDGs but also to provide an enjoyable event for people of all ages through art created from garbage. On the day of the event, various activities related to garbage, such as talk events and workshops, were conducted to make SDGs more relatable. Many people, including local residents and those interested in environmental issues, attended the event.
Activities for FY2023
Building a Supply Chain for "Horizontal Recycling" of Aluminum Cans towards Achieving a Circular Economy
Toyo Seikan Group Holdings, Sumitomo Realty & Development Co., Ltd. ("Sumitomo Realty"), and UACJ Corporation ("UACJ") have jointly established a supply chain for "horizontal recycling" of used aluminum cans, where they are recycled into raw materials and utilized again for aluminum can manufacturing. After conducting test operations in 2023, the supply chain officially commenced operations in April 2024, starting from office buildings owned by Sumitomo Realty in Tokyo.
In this newly established supply chain, aluminum cans discarded from Sumitomo Realty's office buildings undergo the recycling process and are delivered as recycled materials to UACJ's factories, where they are processed into aluminum sheet products. Ultimately, these aluminum sheet products are reused within the Toyo Seikan Group to produce aluminum cans and beverage aluminum cups called "Lumisus®."
Furthermore, to raise awareness and promote recycling consciousness among office users, Sumitomo Realty plans to introduce and utilize "Lumisus®" as outdoor beverage cups, starting with events such as the Sakura Festival held in their offices. The cups will follow a similar scheme to aluminum cans for horizontal recycling.
Aluminum primary metal is predominantly imported, making it susceptible to international influences. Achieving horizontal recycling promotes the substitution of aluminum primary metal with recycled metal, contributing to domestic resource circulation and reducing greenhouse gas emissions.
Opening Event of “Zero Waste Fest 2023”
The Group partnered with the Takizawa Garbage Club, organized by garbage collector and comedian Shuichi Takizawa (a member of comedy duo Machine Guns) on a waste reduction initiative to raise public awareness.
The Takizawa's club held the Zero Waste Fest 2023, a month-long campaign from May 3, 2023 (“Garbage Day”) to May 30, 2023 (“Zero Garbage Day”), in various locations across Japan. On May 3, the first day, we co-hosted the opening event of the Fest at the Group's head office building in Osaki, Tokyo, under the theme of ""Embrace the SDGs not out of obligation, but out of desire."" The event was designed to create an opportunity for participants to find fun in recycling activities through various small programs that are linked to everyday life.
Admission was granted in exchange for recyclable waste containers brought by the visitors. At the venue, we arranged interactive exhibits with products developed by the Group, including a prefabricated cardboard tent that is recyclable; Captain Box, game-like equipment to collect used PET bottle caps; Re-CUP WASHER, a cup washer to promote paper cup recycling; and Loopiece, craft materials “upcycled” from used glass bottles. The stage featured a talk session with Mr. Takizawa, other comedians and guest speaker Ken Noguchi, an alpinist and environmental activist, as along with a picture-story show and music performance themed around waste issues and the SDGs.
The event was attended by around 300 individuals from the neighborhood and other areas.


Initiatives towards the Deployment of the Cup Cleaning Machine "Re-CUP WASHER"
Tokan Kogyo is actively working on the implementation of the "CUP TO CUP Recycling System" using the cup cleaning machine "Re-CUP WASHER" to recycle paper cups and convert them into recycled cups. In the fiscal year 2023, they carried out the following initiatives and will continue to expand the deployment of Re-CUP WASHER to contribute to the realization of a circular economy:
