Effective utilization of naturally durable wood biomass offers an overlooked source of potential wood protectants
Snapshot: Forest Service researchers at the Forest Products Laboratory in Madison, Wisc., are evaluating extractives as potential next-generation wood preservatives. This bio-rational approach offers environmentally friendly alternatives to wood preservatives and provides a utilization platform for underutilized and invasive wood species.
The stakes in the image are southern pine pressure treated with extractives of naturally durable wood species. These stakes have been installed in ground contact in Mississippi and Wisconsin and will be evaluated for the next 10 years.
