Washing Systems, LLC receives
the 2019 Green Chemistry Challenge Award from the US EPA

On June 7 (local time), Washing Systems, LLC (headquarters: Cincinnati, Ohio; hereinafter, WSI), a subsidiary of Kao Corporation, received the 2019 Green Chemistry Challenge Award by the United States Environmental Protection Agency (EPA) and the American Chemical Society (ACS) for its wash process for commercial laundry companies, TRUpathTM.
The Green Chemistry Challenge Award has a 23-year history and is given to companies, organizations, and individuals that develop innovative green chemical technology that turns latent environmental problems into business opportunities and contributes to innovation and economic development.


WSI develops and provides industry-leading wash processes for water-based commercial laundry companies mainly in North America. It also provides integrated detergent supply systems, best-in-class customer service, and boasts a large market share.
The award-winning TRUpathTM is a wash process that eliminates alkali (sodium hydroxide) on the large majority of items processed. Alkali is environmentally harmful but widely used in the commercial laundry. TRUpathTM enables shorter wash time, less water use, and low-temperature wash leading to reduced fuel consumption.
WSI has long been working on reducing the use of environmentally harmful raw materials that are widely used in the industry, such as NPE*1 and phosphates. WSI has already been awarded the Platinum Level award by the Ohio EPA for two consecutive years in 2017 and 2018 for its contribution to making the commercial laundry industry greener. This is the first time WSI is honored by the US EPA.
"We are both humbled and extremely proud to be selected as a recipient of this award. The selection criteria are exhaustive, and set a very high standard. I believe this elevates our entire laundry industry," stated John Walroth, CEO.
