How one public works department developed a spec to use recycled aggregate which allows for construction waste — including toilets
Currently, Whatcom County’s two regional solid waste management companies accept toilets for a small fee and provide them for future Poticrete installations. This use, along with other options for recycled aggregate, will help the city include more than 400 tons of recycled materials in concrete alone in street projects each year, Freeman points out.
“This is a situation where everyone wins,” he says. “This project and this use of toilets is an example of the strategic risks that public agencies need to take in this day and age to encourage local markets that support recycled materials and more sustainable road projects.”
This project received the first GreenRoads certification, according to Freeman.
