Technology Helps Turn Salvaged Trees into Moneymakers

When insect scourges run rampant through forested ecosystems they can leave behind entire stands of dead and dying trees – especially if that scourge is the spruce budworm. In the Upper Midwest, where the spruce budworm infests forests on a cyclic 30-50 year pattern, forest managers oftentimes use salvaged logs from the dead and dying trees to produce low-value wood products, such as wood pulp, or merely count the dead trees as a loss and leave them standing.

But Forest Products Laboratory (FPL) researchers developed ways to evaluate the quality of salvaged wood and sort out the higher-quality wood for production of cross-laminated timber (CLT) – a high-value wood product that can increase forest revenues. “We’re at the point of demonstrating commercially available technologies,” said FPL engineer Robert Ross, “and the idea that we can take high-grade material out [of dead tree stands].” Continue reading

Environmental Building Declarations: Analyzing a Structure from Cradle to Grave

The USDA Forest Service, Forest Products Laboratory, in cooperation with US WoodWorks, engaged the Athena Institute to prepare an environmental building declaration (EBD) for the Design Building on the Amherst campus of the University of Massachusetts. This is a new four-story 87,573 square-foot home for three departments: Architecture, Landscape Architecture and Regional Planning, and Building Construction Technology. The cross-laminated timber building, designed by Leers Weinzapfel Associates Architects with structural design engineer Equilibrium Consulting, was completed in January 2017. Continue reading

CLT and ‘America’s Forests’: Television Program Highlights Benefits of Sustainable Building

A new public television series focused on maintaining and sustaining healthy forests in America kicked off by exploring cross-laminated timber (CLT) and the future of green building.

In the premiere episode of America’s Forests with Chuck Leavell, music industry giant and tree conservationist Chuck Leavell steps into the world of sustainable construction, as he investigates the innovative possibilities of building with CLT. Continue reading
