“We were surprised that simple sugar could bind sand together so strongly,” Kaichang Li, a professor of wood science and engineering at Corvallis, Ore.-based Oregon State University (OSU), told Inner Circle. “The binder systems we’ve developed should be much less expensive than existing sand binders and do not pose toxicity concerns,” he added, noting that materials such as furan and phenol formaldehyde resins can emit toxic fumes during the mold-making and metal-casting process.....
