About the 2017 Cleantech Open Northeast Regional Winners:

change:Water Labs

Category: Agriculture, Water, and Waste

Based in: Cambridge, MA

Summary: change:WATER Labs is developing a toilet that can be deployed to every vulnerable household. We are developing a revolutionary evaporative ("self-flushing") toilet-a low-cost, compact, off-grid, portable solution that decouples household toilet access from sewerage infrastructure. Our evaporative toilet rapidly shrinks onsite sewage accumulations down to 5-10% of produced daily volumes. Sewage is 85-99% water. By cheaply, quickly eliminating that water, we eliminate 90% of the sewage problem.


Category: Chemicals and Advanced Materials

Based in: Waltham, MA

Summary: CoolComposites is improving the thermal performance of buildings with an additive called CoolFlux. By storing energy when heated and releasing that energy when cooled, CoolFlux automatically lowers the use of air conditioning by 50%. Competing products require substantial building modifications, are very expensive, or both. Their additive doesn’t change the look, feel or installation of materials that architects and contractors are already using, and is priced for a payback period of under five years.


Category: Information and Communications Technologies

Based in: Cambridge, MA

Summary: Joro provides real-time, automated, holistic carbon emissions tracking and tailored feedback to help citizens make energy-saving choices about everyday activities and purchases. The Joro platform enables users to compete and engage with friends and family, in order to earn rewards for environmentally conscious consumption, to save money, and to reduce their overall carbon footprints.

P2S Technologies

Category: Information and Communications Technologies

Based in: Framingham, MA

Summary: Our innovation is building the first comprehensive and user-friendly, system for corrosion monitoring and detection in pipelines, integrating both hardware and software components. These hardware devices attach to existing wires inside each test point. When a survey device using Lync Reader software is in range, the hardware device broadcasts the calculated AC/DC output values to the reader. Those survey devices then use their internet connection to send the data to our servers. The cathodic protection data is captured and stored in digital form, making it very accessible for reporting and analysis.
