Elephantech Publishes Quantitative Evaluation of Life Cycle Assessment Based Reduction in CO₂ Emission and Water Consumption

Japanese English

Elephantech Inc. (“Elephantech”) is pleased to announce that the company has published an estimate on LCA-based reductions in 1) CO₂ emission, 2) water consumption, and 3) toxic substances when using the company’s Pure Additive™ processing as compared to conventional PCB manufacturing methods.

【Background】
As can be seen with the Sustainable Development Goals (SDGs), environmental friendliness and conservation are gaining traction as global concerns. Amid such global trends, Elephantech believes it is an important corporate responsibility to disclose information on a company’s environmental strategy and has created data visualization to highlight its efforts towards reaching sustainability.

【Results of the quantitative evaluation of environmental impact conducted by Elephantech】 Comparing conventional PCB manufacturing methods to Elephantech’s Pure Additive™ processing, the following results were found.

• 77% reduction in CO₂ emissions when compared to conventional manufacturing methods
• 95% reduction in water consumption when compared to conventional manufacturing methods
• 85% reduction in processes that cause toxic substance emission when compared to conventional manufacturing methods

With regards to CO₂ emissions in particular, if all circuit board in global were to adopt Elephantech’s Pure Additive™ processing, it would have the potential to reduce CO₂ emissions by 268 billion kg-CO₂,equivalent to the reduction of nine 1000 MW-class thermal power plants. ¹

This LCA evaluation is based on the data and calculation logic from Carbon Footprint Analysis of Printed Circuit Board[1] by Winco K. C. Yung et al. of The Hong Kong Polytechnic University. The effect of the reduction is estimated by comparing the carbon footprint of the materials and energies required for manufacturing between the conventional manufacturing method and Pure Additive™ processing. ²

This comparison is based on assumptions at the time of publishing, and while there is an expectation for emissions to be further reduced and improved by technological advancement for both conventional methods and Pure Additive™ processing, there is reason to believe that the latter will maintain its superiority due to it requiring significantly fewer materials and processes.

Under the company’s mission of making the world sustainable with new manufacturing technologies, Elephantech will continue to strive to reduce CO₂ emissions, water consumption, and toxic substance emissions.
