Two types of waste woody biomass are used as feedstock from the surrounding forests: slash and pre-commercial thinnings. Slash piles (leftover tops and branches from timber harvest) would otherwise be burned as part of standard timber harvest management. Red Rock’s usage of this material means that it will no longer be burned in the forest, avoiding significant air and greenhouse gas emissions. Red Rock also uses pre-commercial thinnings, which local timber managers generate to help keep forests healthy and mitigate the risk of wildfire in overgrown timber stands.
