Recycled plastic spheres replace concrete in sustainability tour de force


Make better use of plastic recylate, reduce weight and carbon emissions during shipping, and reduce the time and energy required during construction: these are some of the sustainable highlights realized by a new blowmolded application that makes use of the skills of plastics processor Meredith-Springfield.

The processor's work is part of a project tapping into a patented building and construction technology that may help builders reduce the weight of concrete slabs by 30-40%. Making it happen are extrusion blowmolder Meredith-Springfield Associates Inc. (Ludlow, MA), which has been tasked by neighboring firm Barker Steel LLC (Milford, MA) to supply plastic blowmolded spheres, about the size of a volleyball, for use inside a Cobiax voided concrete system. Barker is the U.S. distributor of structures made using the patented Cobiax procedure, which was developed by a Swiss company. In such structures, plastic spheres are set into steel wire cages, which are then used as reinforcement for concrete structures....
