Green pyrotechnics /firecrackers reported herein are driven by thermite reactions for self-contained and self-sustained exothermic chemical reactions to make heat and sound by the usage of minimal fuel (aluminium), oxidizer (potassium nitrate), and Sulfur. These firecrackers have the potential for generating less emissions (70%) compared to commercial firecracker-based counterparts due to the presence of additives and are therefore designated as “Green firecrackers” or reduced emissions firecrackers. The functional performance and long-term stability of the composition was investigated through sound measurement and different tests, including ageing, thermal stability, and moisture test. The thermodynamics of the facilitated thermite reaction was cross-checked with experimental and theoretical methods. Prevalent mechanism for a substantial reduction in emissions to the tune of about 70% has been discussed. Cost of the green firecrackers is at par with the commercial firecrackers as cost of raw materials being used to prepare the formulation is comparable to the relatively toxic oxidizer substituted. “Green firecrackers” developed and reported here are environmentally benign in nature with higher business potential as far as a green chemistry-based sustainable solution for the society is required.

本文报道的绿色烟火/鞭炮由铝热反应驱动，用于自给自足的放热化学反应，通过使用最少的燃料（铝）、氧化剂（硝酸钾）和硫来产生热量和声音。由于存在添加剂，这些鞭炮与基于商业鞭炮的对应物相比有可能产生更少的排放 (70%)，因此被指定为“绿色鞭炮”或减少排放的鞭炮。通过声音测量和不同的测试，包括老化、热稳定性和水分测试，研究了组合物的功能性能和长期稳定性。用实验和理论方法交叉检查了促进铝热剂反应的热力学。已经讨论了将排放量大幅减少至约 70% 的普遍机制。绿色鞭炮的成本与商业鞭炮相当，因为用于制备配方的原材料成本与替代的相对有毒的氧化剂相当。此处开发和报道的“绿色鞭炮”对环境无害，具有更高的商业潜力，需要为社会提供基于绿色化学的可持续解决方案。
