Modified Atmosphere Packaging (MAP packaging) is finding increasing application for the wrapping of foodstuffs, including meat, sausage and fish as well as delicatessen thanks to its strong barrier against oxygen. MAP packages are typically made of PVC/PE or PET/PE composites and ensure that the food will last longer.

But what happens to the packaging once it is discarded? A recent press release from the European Rigid PVC Films Association (ERPA, Frankfurt / Germany; www.pvc-films.org) showcases a new stormwater attenuation application for used PVC/PE composites packaging, the brainchild of a cooperation between French film manufacturer Cifra (Château Thierry; www.cifra.fr) and water treatment systems producer Hamon Thermal Europe (St. Denis / France; www.hamon.com).

Cifra calanders the PVC/PE packaging recyclates into thick films, which Hamon then turns into profile sheets that are glued together to form water cisterns. Known as “Geolight”, the system forms controllable water reservoirs and can be adapted to the site’s specific characteristics and limitations, ERPA says. Geolight’s advantages include reduced excavation costs, quick installation, low water resistance, reduced risk of flooding as well as less environmental pollution.

ERPA says new projects of this kind are already in the planning stage in both Germany and The Netherlands. PVC package films manufacturers have already dubbed the initiative “pack-upgrade”, the PVC film group – which is part of European Plastics Converters (EuPC, Brussels / Belgium; www.plasticsconverters.eu) – adds.
