The paper presents the method of recycling and quality management in the recycling process of polymeric materials. Recycling of mixed polymer materials is one of the most complex processes in manufacturing. It is important to be able to manufacture the materials of the secondary properties of an acceptable degree of mixed polymer waste. In this way have been eliminated long and costly separation processes. Properties of such materials are polymers which are disadvantageous because constitute them - mainly PE, PP, PS, PVC, PET etc. - are incompatible and form a multi-component system in which the individual phases do not exhibit significant adhesion. In addition, other materials present different types - paper, metals, dyes - act as contamin...
