Post consumer recyclates are obtained from the waste of the end consumer, i.e. the yellow bag or the yellow garbage can. The post consumer waste is collected, sorted by type of plastic (PP, PE, PS) and then shredded, washed and melted down to new plastic granulate. Since the post consumer recyclates obtained in this way can only be used again to a limited extent as primary packaging for food, pharmaceuticals or cosmetics due to the high demands on hygiene and product safety, research has been underway for some time now into new recycling processes for the recovery of plastic waste. In these new methods of chemical recycling, the unsorted plastic waste is returned to the starting products of plastics production by pyrolytic decomposition. By the action of heat, catalysts and solvents, the polymer chains of the plastic waste are shortened and even broken down into monomers. New plastic raw material can then be refined from the basic components obtained. Recycled material obtained by chemical recycling may also be used for packaging materials in the food, cosmetics and pharmaceutical industries.

Pre consumer recyclates are obtained from industrial waste, which is usually generated during production processes, during the start-up of production plants, in the form of sprues or as scrap. Industrial plastic waste is usually produced in large quantities and sorted by type, and can therefore be shredded without major sorting or cleaning effort and then reused. Many plastics processing companies have special plastic mills for this purpose, in which pre-consumer recyclates are produced by shredding the production waste. Unfortunately, there are areas of application for even the highest quality Pre Cosnumer recyclates, which are not allowed to be used due to high demands on product safety and hygiene. For example, the use of recyclates for primary packaging materials in the food and pharmaceutical industry is largely prohibited due to strict legal requirements of the regulations EU 2022/1616, EC 10/2011 and EC 1935/2004. Even in cosmetic packaging, recyclates may only be used to a limited extent and under certain circumstances.

A recycled plastics material, or recyclate, is generally the product of a recycling process. Transferred to the recycling of plastics, the term "recyclate" is thus a synonym for recycled, i.e. reprocessed plastic waste. Although a wide variety of materials, such as wood, paper or glass, can be recycled, the term "recyclate" is mainly used in relation to recycled plastics. By reusing the valuable raw material plastic, not only resources but above all the environment can be protected. Depending on the condition of the plastic waste to be recycled, recyclates can be obtained by different reprocessing methods. Basically, plastic recyclates are divided into two main categories, the "Pre Consumer Recyclates" and the "Post Consumer Recyclates":
