Nanostone Water, Inc. is named in the 2015 Global Cleantech 100 Ones to Watch

List Recognizes Up-and-Coming Private Companies in Clean Technology

Eden Prairie, MN, USA – January 26, 2016: Nanostone Water, Inc., a membrane solutions company with a unique portfolio of ceramic and polymeric membranes for water treatment and industrial process fluids, today announced it was named in the 2015 Global Cleantech 100 Ones to Watch list, produced by Cleantech Group, whose mission is to connect corporates to sustainable innovation through its i3 Connect platform and global events.

The Ones to Watch list seeks to highlight a group of upcoming companies that are catching the eye of leading players in the market. They are companies who did not quite have enough market support to make the 2015 Global Cleantech 100 list itself, and who have never been on a previous Global Cleantech 100 list, but who clearly carry pockets of strong support among key corporations, investors, and Cleantech Group analysts within the Cleantech Group’s Expert Panel. The Expert Panel consists of an influential group of 100 panelists who help determine the annual Global Cleantech 100 list.  The diversity of panelists results in a list of companies that command an expansive base of respect and support from many important players within the global cleantech innovation ecosystem.

“Nanostone Water is honored to be a recognized by Cleantech’s Expert Panel, and we are proud to serve our customers with our new, innovative ceramic UF monolith and broad portfolio of robust polymeric membranes,” said David Jellison, Nanostone’s CEO.

This year, a record number of nominations for the annual Global Cleantech 100 list were received: 6,900 distinct companies from 60 countries. These companies were weighted and scored to create a short list of 323 companies. Short-listed nominees were reviewed by Cleantech Group’s Expert Panel, resulting in the Ones to Watch list, in addition to annual the Global Cleanteh 100 list. To qualify for the both lists, companies must be independent, for-profit, cleantech companies that are not listed on any major stock exchange.

About Cleantech Group Founded in 2002, Cleantech Group’s mission is to accelerate sustainable innovation. Core to this mission is i3, an online platform that connects corporates with innovation, at scale, by allowing them to find, vet, and connect with start-ups—efficiently building an innovation pipeline.
