The ecological and economical treatment of derivatives from non-renewable sources is a current trend in the development of polymer systems, which supports global activities leading towards a sustainable environment. This article, therefore, deals with the effective management of powdered waste material (PA 12), which is no longer usable for additive technologies. Throughout recycling process, the material was modified and optimised for injection moulding technology, and transformed into pellets in the next step. The resulting thermoplastic material has a wide application potential, especially with regard to its very good mechanical and physical properties, which are evaluated in this contribution. The advantages of the resulting polymer are based, among other things, on the economic aspect, whereby a material with the nature of a structural plastic will be more available compared to plastics from an analogous category.
