Soybean Sealant Used on SD Roads

The South Dakota Soybean Research & Promotion Council (SDSRPC) recently announced it has partnered with the City of Sioux Falls to treat roads with a soy-based concrete sealant.

PoreShield, developed with funding from the South Dakota Soybean Checkoff, was applied to Marion Road on Sept. 9, starting at the intersection of Madison Street. The soy-based sealant is reportedly proven to provide protection against water, freezing, thawing and salt, and increases the life of concrete by over five times.

“We’re always looking for new, innovative ways to improve roadways in our community, especially when we can use bio-based products,” said Nick Rezac, Engineer for the City of Sioux Falls. “The application was fairly simple and will bring great value for years to come.”

According to the SDSRPC, a 60-pound soybean bushel contains approximately 12.4 pounds of soybean oil, with 7.7 pounds of soybean oil per gallon of PoreShield and on average utilizing 200 bushels of soybeans per mile of highway joint.

SDSRPC reports that PoreShield has also been applied on patios and university walkways, fire station sidewalks, driveways and can be used in construction and architectural projects like parking lots, garages, curbing, buildings, dams and pipelines.

“We value partnerships with the communities we all work and live in,” said SDSRPC Chairman Tim Ostrem. “Opportunities where we can bring quality products to our communities and drive demand of soybeans for our farmers are a win-win for everyone.”

Other Soybean Products

Researchers from Kansas State University reported in 2017 that they developed and patented a new resin made from soybean, corn and other plant oils to formulate “the first plant-based resin of its kind.” Recommended applications include re-adherable painters’ tape, labels, packing tapes, stationery notes and other adhesive uses.

The resin could also be used in coatings for wooden surfaces, slick magazine pages, bags of potato chips and other items needing shiny and protective surfaces that are either flexible or rigid.

Initial funding was provided by the Kansas Soybean Commission and the United Soybean Board. Additional funding sources include the U.S. Department of Agriculture and the National Institute of Food and Agriculture.

The patent was issued to the Kansas State University Research Foundation, a nonprofit corporation responsible for managing technology transfer activities at the university.
