Cleantech covers a broad spectrum of growing industries. From state of the art software to innovative methods of hydroponic gardening, electric vehicles to biodegradable jerseys for marathon runners, cleantech is an essential component to improving quality of life and growing the economy in a responsible and sustainable manner.




Ento Foods is exploring the development of sustainable food ingredients derived from edible insects protein powder and omega -rich oils. Insects require less water, animal feed and land, than conventonal protein sources. Sustainable, nutritious products from insects can alleviate pressure on resources that are currently used to raise animals for meat as well as reduce the impact of fish farming. Ento Foods is led by Charles Wilson, a recent law graduate of the University of Oregon, and Yesenia Gallardo from Yale University.

Infinity Homes is developing a sustainable small home construction process that sources all building materials from the waste streams they contribute to. Their goal is to save 90% of home owners’ HVAC costs by adhering to Passive House energy efficiency standards. Infinity Homes is led by Amanda Stowe, Zac Neubauer, and Joe Brinkman, Entrepreneur Scholars at the University of Portland.

Kale Tek is developing a water resistant spray by extracting the microcrystal surface of kale leave.

The group is looking at testing the product on different surfaces, but sees potential in fabric and wood applications as well as agricultural applications. Kale Tek is led by Joshua Proto, Emily Kelley, Ian Dechow, Jonah Svihus and Blake Slatengren, biochemistry and liberal arts students at Lewis & Clark college

Liquid Wire has developed a highly conductive thermal material that could allow for heat harvesting also can be used as printable fluid to power electronic devices in soft robotics and wearable products. Liquid Wire is led by Mark Ronay, an electrical and computer engineering graduate student at PSU, and Bahar Ajdari, a physics Ph.D. student at PSU.

Agriculture requires the application of a high volume of fertilizer to grow as much food as possible. Since the amount of fertilizer is often more than the uptake rate of plants, extra dissolved nutrients make their way into water, leading to contamination of drinking water. The Living Filtration System is a regenerative technology for agriculture which captures excess nutrients in runoff and improves soil health. The team is led by Alison Lewis, Casey Howard, Wade Hanson and Matt Jorgensen, landscape architecture students at the University of Oregon.

Ocean Hexapod aims to radically improve the cost and efficiency of wave power generators by using a robot that can move along six different axes. Ocean Hexapod is led by Jonathan Bird, an associate professor of electrical and computer engineering, Wei Qin and Mojtaba Bahrami Kouhshahi graduate students at Portland State University.

Vineyard managers plan pesticide schedules using temperature and humidity data recorded from weather stations.  This approach fails to take into account topological and microclimate variability. Plantalytics developed a network of temperature and humidity sensors to provide vineyard managers a detailed, real-time map of their vineyards. Plantalytics is led by Ben Nahir, Doug Beyers, Brad Scardino and Troy Brown, business and engineering graduate students at Portland State University.

Energy production is a major contributor to climate change. Actions to reduce carbon output can be done now with the existing infrastructure without waiting for new energy technology to be developed. As 20% of power is lost between generation and consumer electrical outlets. Transposition is developing a system that increases the efficiency of the electrical grid by interfering with losses that occur as electricity transfers between power lines. Transposition is led by Autumn Engh and Brianna Dickenson, renewable energy engineering graduate students at Oregon Tech

When timber is falling, the main goal of the cutter is to fall directional lyso there is the least amount of breakage when the tree hits the ground. Tree  Dog is designing a safe tree-cutting system that holds a cut tree in place and directs its fall to a desired location. Tree Dog is led by Dylan Gould and Zach Caprai, business and engineering students at Oregon State University.

A key environmental problem is groundwater and surface water pollution from landfill leachates. Landfills are the common practice for municipal solid waste disposal. Seepage of landfill leachate into underground aquifers can make them unsuitable for human use. Water Boys developed an on-site treatment system to both remove pollutants and recover resources from landfill leachate. Water Boys is led by Steve White and Hossein Tabatabaie research associates from Oregon State University.
