Project Profile – South Barrington Landfill

Facility: Closed Landfill

Location: Barrington, Illinois

Owner/Operator: Republic Services

System: Leachate Phyto-Utilization with Hybrid Poplar ETCap®

Installation Year: 2009

Design: Rows of hybrid poplar and willow trees over 9 acres

Phyto Systems Utilize Leachate as a Resource

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 poplars and willow trees.  The trees then utilize the leachate, normally considered a waste, as a resource by absorbing the needed moisture and contaminants, which act as micro and macro nutrients to fuel plant growth.

The South Barrington system has been a great success, with not a single load of leachate hauled off since operation began.  As of September 2018, the system has processed more than 11 million gallons of leachate.  The system has reduced the facility’s carbon footprint by sequestering CO2 and avoiding tanker truck emissions, as well as create significant long-term savings for the facility and habitat for wildlife.
