Biodegradable plastics

Biodegradable plastics are special polymers designed to biodegrade after use. Also, biodegradable plastics have physical characteristics that are very unique and do not match those of conventional polymers. The processing of biodegradable plastics is also unique, as they are very susceptible to heat and mechanical stress. The availability of technologies to handle the so called post-industrial scrap or rejects is scarce to inexistent.

The new Bio-Gran technology by CMG

Conventional granulation equipment cannot handle biodegradable production rejects adequately. As a consequence, those are not reintroduced in the production process and are given away for random recycling attempts.

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