Starlinger - recycling technology for post-consumer plastics

1 2 3 4 Odour reduction technology Post-consumer plastics often contain migrated substances from food, cosmetics or detergents, which cause an unpleasant smell during the recycling process. But also residues of monomers, oxidation, as well as decomposition products (VOCs – volatile organic compounds) can be the reason for unwanted smells in regranulate. Depending on the polymer type, source or type of the odour, its intensity, and the specifications of the produced regranulate, Starlinger recycling technology individually 1. Material preparation: The SMART feeder heats and homogenises the input material until the ideal operating point is reached. Highly volatile odours are already extracted during this process. adapts the recycling and odour reduction process. It includes the steps material preparation, melt filtration, degassing and post-treatment. 2. Melt filtration: In continuous melt filters solid contaminants are immediately scraped off the filter media. This ensures that contaminants such as paper and organics can no longer release odour. 3. Degassing: The C-VAC degassing module placed after the melt filter increases the melt surface by 300 %, thus achieving an extremely high degassing efficiency. This results in permanently removing also deeply embedded odours. 4. Post-treatment: The odour reduction process is completed after pelletizing. The most persistent odours are reliably extracted and permanently removed from the regranulate.
