We construct machines that are used in the plastic recycling process. PET are handled by our equipment. Since each type of plastic has unique properties and the production of recyclable new ground materials must meet a variety of demands, recycling requirements may differ.


Shredded waste material reaches the washing line as polluted PET flakes, which are first passed through a friction washer to remove light pollutants like liquids and paper with cold water. Following the first wash, the material stream is dried and more contaminants, such as dust and sand, are separated. In a mechanical dryer, this is achieved. Another washing stage can be needed for highly contaminated material, such as to remove adhesives from labels and meet food grade requirements. The flakes are immersed in a mixture of hot water washing solution in a continuous PET hot washer before being rinsed in a friction washer. PET flakes can be separated from lighter plastics such as PE/PP from bottle caps in a sink-float tank. Finally, a mechanical dryer will dewater the PET flakes, while a thermal dryer will dry the polyolefins.
