Project Profile – Mallard North Landfill

Facility: Closed Landfill

Location: Hanover Park, Illinois

Owner/Operator: Forest Preserve District of DuPage County

System: Leachate Phyto-Utilization™ with Hybrid Poplar ETCap®

Installation Year: 2018

Design: Rows of hybrid poplar and willow trees over 14.5 acres

The Mallard North Landfill is our largest Phyto-Utilization™ system to date, covering over 14 acres of the closed landfill.  Since operation began, the system has processed over 16 million gallons of leachate with flow as high as 25,000 gallons per day.  The system is reducing the facility’s carbon footprint by sequestering CO2 and creating significant long-term savings for the facility and habitat for wildlife.  Read more about the project in Waste Advantage Magazine!

Soon After Planting

Our Phyto-Utilization™ systems use fast-growing and non-invasive plants to consume liquid waste in a GREEN and sustainable way in order to greatly reduce or eliminate the need for other, more costly disposal methods.  The systems are engineered to pump leachate from a pond or tank through a fully automated pre-treatment and distribution process and up to a field to irrigate the rows of hybrid poplar and willow trees.  The trees then utilize the leachate, normally considered waste, as a resource by absorbing the needed moisture and contaminants, which act as micro and macro nutrients to fuel plant growth.
