The aim of the paper consists in the treatment of post-consumer and technological waste ofelastomers and plastomers, according to the 4R principle (reduction, reuse, recycling and recovery)by transforming them into raw materials with added value and integrating them into differentindustries. This will lead to the developing of new processing concepts regarding obtaining newbiodegradable composite materials, with various waste contents (10-50 wt%). The composite isbased on chloroprene rubber, and added post-consumer recycled rubber particles, with size of 45mesh, eco-reinforcing material, and active fillers, plasticizers, vulcanizing agents, antioxidants. Inorder to enhance the compatibility and their level of interaction, the elastomer waste was finelyground (cryogenic mill) and functionalized with potassium oleate. Rubber waste acts as a fillingmaterial which leads to lower carbon footprint of the composite and lower mass. Tensile, tearstrength, elasticity, hardness, abrasion resistance, melt flow index and morphological study (FT-IR)of those composites were examined in order to determine their viability in various application areas.The transformation of waste (cryogenically ground, and functionalized) into new products withadded value will lead to remarkable improvements in the life cycle of raw materials and thesustainable use of this waste, contributing to increasing sustainability, improving eco-efficiency andeconomic efficiency and reducing the carbon footprint on the environment.
