The contribution of aviation industry in managing the time of travel around the world is overwhelming. Though its services are highly needed, the serious threat posed by the deposition of rubber during take-off and landing has to be addressed in the airfield runway to mitigate the ground-based accidents. As rubber is non-degradable in nature, the present work aims to study the use of aircraft tyre rubber waste in the removal of toxic metals like chromium from wastewaters and for partial replacement of sand in the production of rubberized concrete. The characterization of vehicular and aircraft tyre rubber waste shows that the siliceous material is equal and the presence of oxygen is observed in the aircraft tyre rubber waste compared to vehicular tyre rubber waste. The utilization of the aircraft tyre rubber waste for partial replacement of sand in the production of rubberized concrete showed that the slump values and compressive strength are decreased with an increase in the percentage of the tyre rubber waste and the acceptable limits are within 5% range. The removal efficiency of chromium from wastewaters using aircraft tyre rubber waste carbon (ATRWC) was obtained at 67.56% in a batch study for various parameters. From the results, it can be observed that ATRWC can be used as a low cost adsorbent for removal of chromium from wastewaters. [ABSTRACT FROM AUTHOR] |
