Project Profile – Quad Cities Sanitary Landfill

Facility: Closed, Subtitle D Landfill

Location: Milan, Illinois

Owner/Operator: Republic Services

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

Installation Year: 2015

Design: Rows of hybrid poplar and willow trees over 4 acres

The Quad Cities system was the first Phyto-Utilization™ system installed on a closed, Subtitle D landfill, and represents another successful project.  Since operation began, the system has processed more than 8 million gallons of leachate.  The system has reduced the facility’s carbon footprint by sequestering CO2 and avoiding tanker truck emissions, as well as created significant long-term savings for the facility and habitat for wildlife.

Tree Growth - 2019

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.
