MADISON, Wis. — The USDA Forest Service’s Forest Products Laboratory held an Earth Day celebration to showcase the work they’re doing to make the earth greener. The lab’s work revolves around wood and products that come from trees. Researchers study everything from the anatomy of a tree to the ways a tree can be used. “We work on sustainability, we work on reducing our footprint, we want to be more eco-friendly,” said Alicia King, Assistant Director of Communications said. “So, a lot of the research that we do enables us to discover more ways to utilize trees, all of their glory, and all of the fun things that can come from that.” Visitors got a glimpse at cutting-edge research being done at the lab, from testing the durability of different types of wood products, to products that help reduce waste.
