You bet, say researchers at Michigan state university and the USDA’s Forest Products Laboratory in Madison, Wis. The scientists are working on a fiber from digested manure solids that may someday replace sawdust in fiberboard. So far, the experimental product has performed well in mechanical tests, with it meeting or exceeding standard fiberboard requirements. Plus, it does not smell like manure. The real test is whether the product will be accepted by the construction industry.
