For quite some time, the European community has clearly stated that the primary path for reducing microplastics and emissions lies in the recycling of post-consumer plastic materials. For this reason, Baracco Srl has developed specific plants that, combined with compounding extruders, ensure the production of crystallized PET granules. The technology developed by Baracco Srl enables the production of pellets from washed PET flakes, using particularly controlled cutting conditions to obtain high-quality granules. Subsequently, these granules are partially crystallized using an internally designed crystallizer. The process begins with PET flakes, which have undergone a washing process to remove contaminants and impurities. These washed flakes are fed into the underwater cutting system, where they are transformed into granules through a controlled extrusion and cutting process. During the underwater cutting process, operational conditions such as temperature and pressure are carefully controlled to ensure uniform and consistent granule production. This ensures that the resulting granules are of precise size and shape, ideal for use in specific applications. Once the granules are obtained, they are transferred to the crystallizer designed by Baracco Srl. The crystallizer is designed to provide a controlled environment where the PET granules can partially crystallize. This partial crystallization process helps improve the mechanical and thermal properties of the granules, making them more suitable for use in a variety of applications. This report explains in detail the conditions and criteria for the construction of the Baracco plant to ensure what has been achieved on multiple industrial plants already operational since the beginning of the year 2023
