Systematic Evaluation of a Sustainable Plasticizer Derived from Coconut Shell Bio-Waste in a Reinforced Styrene Butadiene Copolymer System

The utilization of copiously available bio-waste significantly contributes to sustainable development and solid waste management. In the present study, the pyrolytic extract of coconut shell bio-waste is evaluated as a plasticizer in carbon black filled styrene butadiene rubber (SBR) compared with conventionally used aromatic oil (AO) at varied levels of 5, 10, 20, 30, and 40 phr. The pyrolysis of the coconut shell was accomplished in an inert environment using a tube furnace. The coconut shell oil (CSO) was evidenced to take part in the curing reaction increasing mechanical properties. Tensile strength increased to 36
