In India, the life of people during festival seasons is disturbed because of the extremely polluted environment. During festival times, people are habituated to use firecrackers to celebrate; bursting and burning of firecrackers leads to environmental pollution. The chemical composition used results in the firecrackers releasing harmful gases during bursting and burning, affecting the quality of life. In this work, the chemical composition of the firecrackers is modified with natural biofuel material to reduce environmental pollution. Among the various chemical compositions, the effect of sulfur on the firecrackers have a significant effect in affecting the environmental conditions. In the proposed work, the amount of sulfur content is reduced by replacing it with tamarind seed powder (TSP). The addition of TSP with the regular composition is used to make modified firecrackers. Its performance is analysed in terms of pollution-related aspects and its performance. The test is conducted as per the industrial standards for modified chemical composition and compared with regular firecracker chemical composition. From the experiments, it is observed that the emission rate of the modified chemical composition is comparatively lesser than the regular chemical composition firecrackers. For regular chemical composition firecrackers, the rate of emissions for CO, CO2, HC, O2, and PEF is 0.032%, 0.020%, 15%, 28.13%, and 0.546% whereas for the modified chemical compositions sample- 1 have 0.018%, 0.10%, 6%, 22.12%, and 0.546%. The modified chemical compositions sample- 2 has 0.016%, 0.12%, 4%, 21.12%, and 0.546%. The discharged rate of CO, HC, and O2 is reduced for modified firecracker composition. The noise level and sensitivity of the modified chemical composition are also compared with regular chemical composition firecrackers. Both noise levels are within the limit prescribed by the Petroleum and Explosive Safety Organization, India. Similarly, the sensitivity of both chemical compositions also meets the requirements.
