It is worth mentioning that the old PET bottle to be recycled does not require manual removal of the bottle caps and labels, but instead automatically removes the bottle caps and labels through a series of physical methods during the treatment process. In addition, the chemical coating removal technology is used to caustic soda. The surface of the PET bottle is removed for the chemical coating remover so that contaminants adhering thereto can be removed. The PET bottle manufactured by this recycling technology has been subjected to microbiological testing by an authoritative organization, chemical composition testing, and challenge test testing. It meets the requirements of the FAO food grade standard, and the product has low acetaldehyde and yellow pigment content, which can satisfy purity and quality. The requirements are particularly applicable to the food and beverage industry, and its cost is 20%-30% lower than the average new material. At present, the Krones company's pilot plant has started operations, and the small-scale plant was officially put into production in Bangladesh in July this year.
Due to the different recycling, sanitary and storage conditions of waste PET bottles in different countries, Krones can also conduct relevant production tests for waste PET bottles from different countries, and conduct corresponding microbiological and chemical tests.
