PET could replace stainless steel beer kegs in a material swap product developers say will be more environmentally friendly and cost effective for the beer industry.
Antwerp, Belgium-based Dispack Projects worked with Quadrant Creative Molding & Systems on a package that combines the PET 20-liter and 30-liter kegs with a glass-reinforced nylon valve system rather than standard steel.
The Dolium tanks connects with more standard filling and dispensing systems while the finished system is both lighter to transport, and — because PET is easy to recycle — doesn't have to be transported back to the beer companies when they're empty.
“Brewers can avoid huge capital investments in pools of metal kegs that have a very low yearly rotation, especially in use on long distance,” said Albert Wauters, the founder of Dispack and inventor of Dolium. “By optimizing the outbound shipment — efficient geometry replacing the stainless steel weight by more product — and by avoiding long distance return transport, we skip important transport costs as well as the excessive energy consumption of a one-way keg.”
Quadrant CMS, part of Japan's Mitsubishi Plastics Inc., developed the injection molded recyclable valve system.
