Minimization and Utilization of Byproduct

Abstract

- Negative effects arising from the presence of waste materials on the environment is a major problem worldwide, requiring emphasizing of the recycling processes and reuse processes. In this context, the objective of the research was based on finding of a for a sustainable development. To date, for a higher recovery of waste rubber is necessary to transform them into reclaimed rubber involving the use of polluting technologies. Thus, through the proposed technology, respectively through the grinding with tools activated in an ultrasonic field, has been possible to decrease rubber particle size and there was obtained a crumb rubber with a particle size of 100–150 μm. It can replace a large proportion of reclaimed rubber from the composition of a type of analyzed rubber, and the obtained results demonstrate changes in the physico-mechanical rubber properties thus produced with effects on the growth of the life of rubber products and reduce environmental pollution. Also, by applying new technology there is a clear improvement of sustainable development indicator (SDI) defined and analyzed in the paper. Currently, worldwide it is put increasing emphasis on ensuring sustainable development through innovation or, in accordance with the European Commission, on eco-innovation (represented by any innovation which may determine economic development and has a positive impact on the environment). Thus, eco-innovation is considered, ―key‖ to competitiveness‖, given that the manufacturing sector is stimulated to shift from methods such as ―end-of-pipe‖ to the ―closed-loop‖, with positive effects on consumption of raw materials and energy (European Comission). These clarifications were the basis of research conducted in the field of waste rubber regeneration, problem solved now by various methods, but that involving many technological operations, that, in turn, determine some environmental
