Contributing Solutions to Social Issues through Business ActivitiesApproach to Green Innovation Products
The following diagram outlines the Toray Group's process and procedures for certifying Green Innovation products. Products are subjected to a two-stage screening process conducted by the divisional committees of group companies and by the group-wide Green Innovation Certification Committee. Those able to demonstrate objective evidence of effectiveness are certified as Green Innovation products.
Green Innovation Product Certification Process
- 1 This includes LCA-related data, T-E2A data, and estimates of CO2 reductions attributable to the product.
- 2 Comprised of members of Toray's Global Environment Business Strategic Planning Department, Marketing Planning Department, and Technology Center Planning Department, as well as outside experts when necessary.
Fiscal 2016 Highlights
Introducing the World's First Waterless UV Offset Printing System Using Water Soluble Inks
Offset printing with conventional oil-based inks involves using cleaning agents that contain volatile organic compounds (VOCs) to wash plates and pieces of equipment. These VOCs are thought to contribute to PM2.5 formation, making it desirable to replace oil-based inks with water-soluble inks.
In fiscal 2016, Toray developed ink materials that incorporate hydrophilic polymers to enable manufacturing of VOC-free inks. The inks are used with Toray's Waterless Plate technology to realize a waterless UV offset printing system using water soluble-inks.
This system is considered to be the most environmentally friendly VOC-free offset printing system of its kind, as it enables waterless printing that does not use VOC-containing dampening water while also using VOC-free water-soluble inks and water-based cleaning agents for washing.
Developing High-Efficiency Organic Thin-Film Solar Cell Module for Indoor Sensors
Society today is being shaped in dramatic ways by the emerging Internet of Things (IoT), creating a need for solutions to power the wireless communication devices which connect all those many things. These devices typically run on AC or battery power, which require wiring or the labor and cost of replacing batteries. Neither solution is sufficient to power the more than a trillion devices that are predicted to be connected via the Internet annually in the future.
In February 2017, Toray developed an efficient organic thin-film solar cell module that is being piloted to supply stable power to drive wireless sensors, in darkly lit indoor conditions such as those only lit by fluorescent light. Toray will further refine the technology with the aim of introducing a commercial thin-film solar cell module by around 2019.
