A solid plan for dead wood

Graduate student Sorin Pasca thinks he has a concrete solution to the problem of what to do with millions of lodgepole pine trees killed by the mountain pine beetle epidemic.

Mr. Pasca, who completed his master's degree in forestry at the University of Northern British Columbia in Prince George in April, spent 2½ years mixing different ratios of wood chips from the infected trees with cement to create a new type of concrete that can be cut with regular woodworking tools, yet is stronger and more attractive than drywall.
