It was about 150 thousand tons/year of waste tire were generated in Taiwan. The bulk of the waste tire nearly 70% which is incinerated for energy utilization pattern. However, the waste tire which is incinerated for “energy utilization pattern”, causing serious environmental pollution and resource wastage for linear economy. An environmental-friendly method of recycling is strongly desired for “circular use of materials” is the best choice for circular economy. Besides, Taiwan has a strong supply chain in the global bicycle industry and is an important base for the production and R＆D of bicycles. In response to a global current trends and export challenges of net zero emissions, circular economy, carbon tariff, and ESG (Environmental, social and governance) in the Taiwan's bicycle industry. Therefore, the goal of this project is to developing technology on the virgin rubber compounds blending with devulcanized waste tire rubber for bicycle tires application. The inhibits self-crosslinking of reclaimed rubber using a bis(3-triethoxysilyl propyl) tetrasulfide (TESPT) silane coupling agent. Simultaneously, the TESPT acts as a sort of intermediary which bonds rubber compounds to inorganic materials (SiO2). Finally, the bicycle tires will decreased virgin rubber consume (beneficial to carbon reduction), and supply the value-added digestion way for domestic waste tire and promote bicycle tires products export trade competitiveness.
