Abstract

Research on recycling, scarcely visible only a few decades ago, is now a very active, fastgrowing discipline, particularly focusing on wastes re-use as second raw materials. This chapter presents an overview on the state-of- art in recycling, the most recent technologies, and recent developments. Rubber and PET are the most frequently recycled polymers, and are particularly addressed to within this chapter. Recent results are presented on rubber/thermoplastic-based micro/nano blends, along with their manufacturing and characterization methods. There are described methods to obtain the rubber-PET composites, based on ground discarded tires as a matrix composites, using as fillers plastic materials (PET, HDPE, and LDPE) and inorganic oxides (CaO, ZnO, and fly ash). Based on the structural and output properties and the chapter outlines the role of various components in the polymer composites. It is demonstrated that inorganic materials in the polymer composites allow obtaining performances unrecorded by pure polymer composites. However, the control of the inorganic material (type, quantity, particle size, and molecular structure) dispersed in polymeric matrix is essential in achieving the expected performance. Using different recipes, the composites can be tailored for various indoor and outdoor applications, as building materials as paving slabs, as thermal and electrical insulators, etc.
