Recycled plastic spheres replace concrete in sustainability tour de force

04/20/2011

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....
