Since 2010, researchers in wood durability and protection at the Forest Service’s Forest Products Laboratory have been evaluating extractives of naturally durable wood species and the potential to protect non-durable wood species. Several wood species studied have been shown to have desirable antifungal, insecticidal, and antiprotozoal effects. Laboratory tests identified several candidate species that have been scaled up into long-term field studies in Wisconsin and southern Mississippi.. Effective extractive utilization provides an innovative way to use woody biomass that isn't always suitable for material applications and could also be incorporated into biomass energy conversion to improve process efficiency. In addition to North American wood species, the researchers also partnered with university affiliates at the Agricultural University of Faisalabad in Lahore, Pakistan, to provide similar solutions for their underutilized durable wood species.
