Protecting grapes from birdsBirds such as robins and starlings enjoy grapes as much as humans do, which tends to cause endless headaches for Willamette Valley growers. Winemakers Dick and Gretchen Evans sponsored mechanical engineering majors Robert Elgin, Peter Cathcart, and Greg Meshnik to develop a solution that would mitigate crop damage by birds before and during the grape harvest season.

Reclaiming wastewater nutrientsThe City of Corvallis wants to harvest and recycle nutrients from landfill leachate to create a revenue stream for the city while cleaning up its wastewater. Last year, a College of Engineering senior project team worked with Multiform Harvest, Inc. and the City of Corvallis Wastewater Reclamation Plant to make a fertilizer called struvite from landfill runoff at the Coffin Butte Landfill. However, the 2011 team discovered that excess calcium was interfering with the reclamation process, so this year’s team addressed that issue. Continue reading

Improving compostable utensilsA Corvallis-based, award-winning startup called EcNow Tech provides compostable cutlery to the Oregon State University dining center and several local restaurants. The cutlery breaks down like green waste and therefore avoids the landfill. The company invited chemical engineering majors Chad Thomsen, Meaghan Jones, and Sean Crawford to investigate which locally sourced materials might serve as superior filler to augment the base from which their cutlery is currently derived.

“It’s really cool from the sustainability standpoint,” said Thomsen, “they’re looking to incorporate locally sourced products and benefiting local businesses.” Continue reading

Many people are familiar with hydroelectric power, and we can thank large dams for a lot of the energy we enjoy in homes. An Oregon State associate professor in mechanical engineering, Kendra Sharp, has been working with a smaller and more sustainable form of hydro energy called micro or pico hydropower that can improve energy accessibility all over the world.
