A plastic recylcing company practices setting the temperature of the contamination removal steps at limits exceeding the optimum setting. Resetting the set points to the supplier’s recommended setting saved 5% of the energy, and improved the product quality.

To recycle PET plastic material, the raw material has to be cleaned of dirt, labels and caps. The production line starts with a grinding and washing process, followed by sorting stations to remove all undesirable contamination.
Installing a pre-sorting station prior to raw material feed to the washing line, served in increasing the production throughput. That pre-sorting station served to remove the sand, dust, fine particles, and partially remove the labels from the input material.
