Cappint semi-liquid solids with geosynthetic layers

A U.S.-based polyethylene and polyester resin/polymer producer recently closed a manufacturing facility in Wilmington, N.C. (Photo 1). The company hired an engineering firm to manage the demolition and removal of the expansive structures and infrastructure. Part of the environmental responsibilities was to also find a viable solution for closing a 12-acre sludge basin. But first, the engineers needed to determine sludge volume and understand which dewatering methods would be the most effective.
