Innovative cleaning technologies for recycling processes of plastics

Removing residues, labels and adhesives from bottle material is a crucial step in plastics and PET recycling. Special cleaning agents and defoamers ensure increased productivity and safety of recycling processes.


Chemetall develops reliable solutions that process the plastic material with efficient cleaners and defoamers in a water and material saving manner. This can significantly reduce costs and increase the quality retention of the material. Plastic flakes processed with Chemetall technologies meet the strictest quality regulations, compatible with the requirements of the food industry. Our products Gardoclean® , Gardobond® additive , Gardo®Pure , and Gardofloc® offer the highest standards for exceptional results in washing and wastewater treatment – including savings of 10-30 percent* in energy consumption, wastewater, and overall process costs vs. traditional processes.

*(Savings are dependent on the plants and process requirements.)


Comprehensive solutions for high quality and consistency

Whether automotive manufacturers, the consumer goods industry, or the apparel and textile sectors, more and more producers are turning to PET recycled material. Due to legal requirements and initiatives, like the European Green Deal, as well as an increased awareness of the need for sustainable use of resources, the market with products made from recycled plastic is growing. Chemetall has more than 20 years of experience in the treatment of plastics and offers technologies for significant preservation of PET flakes, which is important for the reuse and the development of a circular economy.
