Through its Sustainability Innovation (SI) business, Toray Group is helping to realize a sustainable society. The Group defines the products that constitute its Sustainability Innovation (SI) business as products and technologies that contribute to the four domains outlined in the Toray Group Sustainability Vision, and the products are selected based on the Group’s own criteria.

Sustainability Innovation Product Certification Process

To certify its SI products, the Group has established a Sustainability Innovation Product Certification Committee, and products are certified according to the procedures shown in the diagram below.
Based on a three-stage review process involving the relevant divisional committee, supervising organization, and the SI Product Certification Committee, SI products are certified based on objective assessment of their contribution to sustainability.

1. 1 In addition to estimates of CO₂ emissions reduction attributable to the product, and details concerning the intended applications and materials used, analysis results data based on 1) a product life cycle assessment (a method for quantitatively evaluating environmental impacts throughout the entire life cycle of a product, from resource extraction and material and component manufacturing, to distribution, use, and disposal), as well as 2) a life cycle inventory (a list of environmental impact items and the relevant resource inputs and emission outputs over the life cycle of the product or service)
2. 2 Supervising organizations (domains of responsibility):
   ・Corporate Sustainability Strategic Management Division
   Sustainability Business Development Dept. (Circular Economy and Life Innovation)
   ・Corporate Sustainability Strategic Management Division
   Environmental Transition Strategy Dept.(Carbon Neutral and Nature Positive)
3. 3 Sustainability Innovation Product Certification Committee: SI Business Expansion leader (committee chair: General Manager of Corporate Sustainability Strategic Management Division), General Manager of Corporate Marketing Planning Department, General Manager of Technology Center Planning & Administration Department, as well as external experts when necessary

Toray Launches TBW-XHR Series Reverse Osmosis Membrane Elements Enabling Ultrapure Water Production from Recycled Wastewater⁴

1. 4 Recycled wastewater: In recent years, in areas facing severe water shortages, biologically treated wastewater (secondary-treated water) has been further filtered through ultrafiltration and reverse osmosis membranes to produce “recycled water,” which is then used as a source for drinking water and other applications.

Toray Develops High-Precision Hollow Fiber Membrane Module with Nano-Structural Control that Can Streamline Food Production and Reduce Carbon Dioxide Emissions and Costs

Toray Industries has developed a high-precision hollow fiber membrane module for food and bio-related applications by employing its nano-pore structural control technology. This module features a pore size (molecular weight cut-off⁵) around one-quarter that of conventional products, while retaining high heat resistance and permeability. This enhances recovery rates and concentration ratios for proteins and polysaccharides, improving production process efficiency while also helping to reduce CO₂ emissions and manufacturing costs.
These products feature an outside-in module, enabling it to handle even highly turbid and viscous liquids. Toray’s proprietary composite hollow fiber membrane structure ensures high permeability and low fouling⁶. In addition, the module is highly resistant to steam and hot water temperatures of up to 125°C, making it possible to shift from conventional thermal concentration methods to membrane-based concentration, thus helping to cut CO₂ emissions.
In recent years, customer demand has grown for technologies, including those for functional foods, that concentrate relatively low-molecular-weight proteins and polysaccharides. By combining its proprietary composite separation membrane with a new manufacturing process retaining the high heat resistance of the membranes, Toray has realized a module that achieves both fine pore size and high permeability. The new products has a molecular weight cut-off of 10,000–20,000 daltons, allowing it to handle a wider range of molecular weights than conventional products.
Toray has begun shipping samples of the new modules to customers, several of whom are conducting assessments. In the future, customers will be able to optimize their production processes by selecting between the new and existing modules depending on the target molecular weight for concentration or purification.

1. 5 Molecular weight cut-off: Indicates the ability of a membrane to retain substances of a certain molecular weight
2. 6 Fouling: A phenomenon in which contaminants accumulate or block the surface or pores of the separation membrane, impairing its separation performance. Low fouling means the membrane is resistant to such accumulation or blockage.

• Relationship between module’s pore size and liquid permeability (high concentration example)

Full-Scale Launch of Nano-Multilayer Window Film that Delivers Both Solar Control and Transparency

Toray Industries has begun the full-scale rollout of its nano-multilayer film PICASUS^™ IR for window film applications. This innovative film combines outstanding solar control performance with glass-like transparency.
In recent years, driven by rising temperatures and the push for energy saving solutions, demand has grown for window films with excellent solar control performance. In particular, in buildings and automobiles, there is a strong need for highly transparent products that do not impair visibility or spoil views.
To meet these needs, Toray developed PICASUS^™ IR, a film that offers both transparency and infrared-ray blocking capability through advanced nano-multilayer technology, and has deployed it in applications such as automotive windshields. Leveraging this technology, the Company has now released a new standard type with a thickness of 50 μm, suitable for installation on windows of buildings and automobiles. In addition to its high transparency and solar control performance, it offers excellent rework properties needed during installation.
Toray is also evaluating a high solar-control type with approximately 40% improved solar control performance and is working to expand the product lineup.
PICASUS^™ IR also features outstanding electromagnetic wave transmittance, minimizing interference with 5G communications, thereby contributing to both safety and comfort.
