New Bio-Gran Technology Processing Biodegradable Plastics

The new Bio-Gran technology by CMG Granulators was designed to handle small to large quantities of biodegradable polymer effectively and dependably, reportedly preserving all physical and mechanical characteristics of the polymer itself.

According to the company, conventional granulation equipment is not able handle biodegradable production rejects adequately. As a result, those are not reintroduced in the production process and are given away for random recycling attempts.

The Bio-Gran technology was designed to accomplish the objective of allowing recycling and reintroduction of biodegradable production rejects at the production site, by performing adequate size reduction and consequential storage/handling/processing so not to compromise the integrity of the polymer. The reject rate, predominantly deriving by post production finishing phases of the product, can be of a few percentage points up to tens of percentage points.

The first Bio-Gran units are today in operation at industrial sites producing biodegradable plastic products and one test unit is available at the CMG Tech Center in Bologna, Italy. The range of capacities of the Bio-Gran line spans form 200 kg/h all the way to 2,000 kg/h. Bio-Gran is a new patent pending technology and a 100% proprietary development of CMG Granulators.
