Every year 11 million tons of trash enters our oceans, out of which, 6.6 million tons stays within coastal waters. This creates a large impact on waterfront coastal businesses, specifically marinas who are responsible for maintaining the cleanliness of their waters. As a result, Harmful algal blooms and marine debris create massive workflow inefficiencies by forcing employees to clean by hand. That's why we have created a "Roomba" for marinas that autonomously skims for trash, collects oil, and reads water data in live time. We give predictive analytics on the next pollution event and automate the cleanup processes so that marinas can run efficiently and stay informed about the health of their waters.

Crystal Clear Technologies is reclaiming clean water the way nature intended. By using waste shrimp and crab shells to create a nano coating that mimics ocean bottom dwellers, which filter out the impurities in the water left behind from the upstream ecosystem, we are able to separate toxic metals like selenium from power plant wastewater. Our sustainable solution is simple (like a home water filter on the end of your kitchen sink) and costs 70% less to install than the current next best solution on the market and 20-30 percent less to operate while terminating end-user liability for the utilities because the nano coating binds to the toxic metals in perpetuity so they can be disposed of in a non-hazardous state. An independent analysis conducted at Arizona State University shows CCT's chitosan-based, NMX technology as far and away the best of the 38 substrates they tested to remove selenium from water, and with new pending EPA regulations on the level of toxins allowed in power plant wastewater, there is an entire market of over 500 domestic coal and natural gas steam generated utilities that need a solution or risk the potential of fines, closures and trillions in stranded assets. CCT's NMX technology is the only one currently on the market capable of meeting these new, higher standards.
