Teijin Cordley and WR Supply Announce
Japan’s First Project to Recycle Release Paperfor Artificial Leather Manufacturing
Tokyo, Japan, August 21, 2023 --- Teijin Cordley Limited and WR Supply Inc. today
announced they will jointly develop a new process for recycling release paper fromartificial leather manufacturing. Using the technology to manufacture the base paper for
artificial leather release paper using raw materials derived from 100% recycled paper, it
will be possible to recycle the used release paper into recycled base paper and otherpaperboard products. The new process incorporates WR Supply’s EB Series base paper.
When used to replace conventional products, EB Series base paper is expected toreduce CO2 emissions from manufacturing new base paper and incinerating used release
paper, as well as promote recycling. This achievement will be a first for Japan.

Release paper made with EB Series base paper featuring 100% recycled content

Teijin Cordley is the Teijin Frontier Group's high-grade artificial leather business; WR
Supply is a venture focused on ecologically recycled products and environmentalconsulting. Teijin Cordley has been promoting environmentally friendly products andmanufacturing processes, such as using recycled raw materials for artificial leather basefabrics and using water-based polyurethane without organic solvents. Teijin Cordley andWR Supply will start recycling of used release paper with Rengo Co., Ltd., a corrugatedboard, paperboard and packaging specialist, at the end of 2023. The two companies willcontribute to the realization of a recycling-focused society by working with the release
paper and artificial leather industries to build a system that advances sustainable
recycling.

Promoting Circularity
Release paper used in manufacturing artificial leather is a two-layer structure comprisedof a base paper and a resin coating. The resin is used as a mold to transfer patterns andtextures such as natural leather markings and geometric designs to the artificial leather
surface. In the new collaboration, Teijin Cordley will collect used release paper from its
artificial leather manufacturing production. Rengo will recycle and process the usedrelease paper, and produce EB Series base paper in accordance with WR Supply’spatent. Rengo will use the recycled release paper for other kinds of paperboard. WR
Supply will sell the EB Series base paper to manufacturers of release papers. To
complete the circle, Teijin Cordley will purchase release paper made with EB Series basepaper and use it for artificial leather production.
Reducing CO2 Emissions and Conserving Trees
WR Supply’s patented process and Rengo’s paperboard manufacturing technology
enable recycled paper to be dissolved in water, avoiding the need for heat and chemicals
to separate pulp chips. These environmentally impactful ingredients, as well as the fromvirgin pulp. Using this novel method reduces CO2 emissions during manufacturing byapproximately 60 percent, according to studies by WR Supply. Further, thanks to the useof 100 percent recycled content, there is no need to cut down additional trees. For
example, when 10,000m of conventional base paper is replaced with EB Series basepaper, approximately 100 acacia trees can be conserved. By recycling the base paper
portion of used release paper from artificial leather, Teijin Cordley will be able to reduce
CO2 emissions from incineration by approximately 100 tons per year, and to reduce thevolume of industrial waste derived from used release paper by 80 percent per year.
Importantly, EB Series base paper delivers the same quality as conventional base paper,even though it is made from recycled paper.
