    Plastic becomes recycled plastic

    Plastic can take on many different properties depending on its composition. This makes it so practical and versatile – whether as packaging, in automotive construction, as textiles, or as household items, from mixing bowls to rubber ducks.

    Anyone who can modify the material’s properties also determines what can be made from recycled plastic. This not only increases the possible applications but also advances the circular economy.

    At the competence center, Interzero Plastics Innovations is researching the efficient use of our raw materials: formulations are being developed that give the granules the properties required by customers in the plastics processing industry.

    Interzero receives patent for previously impossible mechanical recycling process - HDPE for bottle production made from 100% used packaging from the Yellow Bag for the first time

    hdpe bottles interzero recycling

    The patented recycling process was developed in the company’s own competence center for plastics recycling and involves the production of a recycled plastic material from lightweight packaging (LVP) containing at least 80% HDPE and is used in the production of blow-moulded products.
    This is a mechanical recycling process in which a special combination of additives produces high-density polyethylene (HDPE) with a flowability during processing that is comparable to that of new plastic. The material used consists of 100% used packaging from the Yellow Bag in Germany. The new recycling process does not require the addition of newly produced plastic or the re-sorting of used packaging.
    Packaging can be produced according to individual requirements, including bottles that can be used for products such as detergents and cleaning agents.
