“…The changes refer to the mixing ratio of chemical powders. Various testing procedures like thermal analysis, sensitivity analysis (friction & impact) and performance testing (noise level of recrackers) are performed for both the existing and modi ed chemical composition and it is compared (Manikandan et al 2019).…”

Environmental pollution is one of the major concerns leading to the rise in the temperature of the earth's surface. Owing to this serious concern, many countries in the world are facing so many environmental disasters every year. Hence, it becomes the need of the hour to act immediately to reduce environmental pollution so that the future becomes safer. Fireworks form an integral part of the Indian Subcontinent in almost all the festivals and cultural rituals. This results in the emission of a huge amount of various toxic fumes that directly affect the environmental purity of the air. The objective of the current research work focuses on the reduction of pollution caused due to the emission from burning reworks. One of the important ingredients used in pyrotechnics is ash powder. The traditional ash powder composition contains aluminium powder as fuel, potassium nitrate as an oxidizer and Sulphur as an igniter at de ned levels. To reduce the impact of toxic emissions in ash powder, an organic compound like Sargassum wightii brown seaweed powder is used as a replacement at prescribed levels and the experimentation is carried out. It is found that the Sulphur weightage in the ash powder composition can be replaced up to 50% with the Sargassum wightii brown seaweed powder without affecting the traditional performance of the ash powder. To study the emissions taking place in the ash powder composition, a specially designed ash powder emission testing chamber has been developed. Upon testing, it is evident that the ash powder composition with Sargassum wightii showed that there is a reduction in toxic emission upto 21% on the modi ed ash powder. This helps in generating cleaner emission and leads to attain greener pyrotechnics norms.
