Poplar trees are useful in a variety of environmental applications, in addition to being a promising bioenergy crop. Poplar farms can sequester carbon, improve water quality, and cleanup contaminated industrial sites. Poplar can be used in environmental applications to “polish” treated wastewater, remediate contaminated soil, and contain landfill leachate and agricultural runoff.
These topics and others are featured in the WSU Extension publication, “A Roadmap for Poplar and Willow to Provide Environmental Services and to Build the Bioeconomy.” A second publication, currently in-review, “Growing Poplar for Environmental Applications in Washington State” will describe projects in Washington State where poplar is being grown for wastewater management, phytoremediation, landfill leachate control, among other uses. Once released, this publication will be available through WSU Extension Publications.
