Recycled granulate without disturbing smell

Permanent odour reduction: Smell the difference!

You would like to produce high-quality regranulate, but your input material is smelly, and consequently your regranulate, too?

This is a problem that many plastics recyclers are facing, especially when reprocessing polyolefin packaging waste. Recyclers of post-consumer plastic waste often have to deal with materials containing migrated substances from food, cosmetics, or detergents. But also residues of monomers, oxidation, hydrolysis and decomposition products (VOCs - volatile contaminants) can cause unwanted smell in recycled pellets.

Starlinger is presenting a technology at K 2016 that reduces the smell during and after recycling significantly and allows recyclers to "upcycle" their end product. The method works without additives, achieving excellent resin quality with improved smell on a permanent basis. The odour reduction process consists of three steps: material preparation in the SMART feeder, where the material is heated and homogenised until the ideal operation point is reached; the C-VAC degassing module with 300 % increased melt surface for highest possible degassing efficiency, and the Smell Extraction Unit which gives the regranulate the final touch. The result: up-cycled, permanently smell-improved regranulate of highest quality that can be used in a wide range of applications.

Smell the difference: Visit Starlinger recycling technology in Hall 9 at the K show in Düsseldorf and compare different input and output materials before and after this advanced recycling method.
