University of Maine Process Development Center made the prototypes for Maine Coasters + Bio Boards using pine and spruce wood pulp as a base along with spent grain and vegetable dyes. Maine-based paper mills have already begun producing the coasters.
“Our pulpboard is unlike anything else on the market,” says a statement on Maine Coasters + Bio Boards’s website. “We use softwood pulp native to Maine, combined with spent grain from local breweries, to form a multilayered web. It is highly absorbent with a smooth surface, ideal for offset lithographic printing.”
Currently, nine out of every 10 beverage coasters in the U.S. come from raw materials in Germany, a company spokesman told Woodworking Network. “Maine has the natural resources, infrastructure, and world-class research facilities to make them in-state. That’s our goal. We want to create bio-based products locally that are healthy for the environment and connect consumers to their favorite brands.”
There are over 100 craft breweries in Maine.
