Research Idea Details

New and retrofit technology for capture of gross and fine plastic waste within DOT ROW

Research Idea Scope

How to effectively capture waste plastic debris (cigarettes, syringes, bags. etc.) prior to discharge from inlets, ditches/curbs, and culvert outfalls to receiving waters that retains designed hydraulic flow characteristics. What is required for plastic waste debris maintenance and disposal (time, people, money).

Research tasks may include:
Literature review, design of prototype technologies for gross trash/waste capture, lab/field testing to quantify capture performance, and design specifications for successful technologies.

Urgency and Payoff

Trash management requirements and discharge limitations are an increasing common requirement in NPDES stormwater permits nationwide. Additionally, the public is demanding that state DOTs do more to capture and remove trash from the right of way and prevent the discharge of plastics into waterways. Capture and removal of waste plastic debris within the upland drainage area prior to aquatic deposition is one mechanism for the reduction of microplastic generation. Keeping needles and other biohazards from entering public waters is an important public health and safety measure.
