Defining a 'Green' Cracker
First, let's clear up a common misconception. Green crackers are not silent, nor are they without smoke. Developed by the Council of Scientific and Industrial Research–National Environmental Engineering Research Institute (CSIR-NEERI), they are reformulated
fireworks designed to be less polluting. The primary goal is to reduce particulate matter emissions by at least 30-40% compared to traditional firecrackers. They achieve this by altering the chemical composition, using additives that suppress dust, and avoiding a list of particularly dangerous substances. Think of them as a 'healthier' option, not a completely 'clean' one.
The Supreme Court's Big Five Ban
The most significant regulations stem from a 2018 Supreme Court ruling that banned several toxic heavy metals from being used in any firecrackers. The prohibited list includes lithium, arsenic, antimony, lead, and mercury. These chemicals were commonly used in traditional crackers to produce vibrant colours and effects but are notoriously harmful to human health and the environment. Inhaling fumes containing these metals can lead to severe respiratory issues and other long-term health problems. This ban applies to all firecrackers, whether they are labelled 'green' or not.
The Contentious Case of Barium
Barium nitrate is perhaps the most talked-about chemical in the firecracker debate. It acts as an oxidiser, making fireworks burn more intensely, and is also responsible for creating brilliant green sparks. The Supreme Court explicitly banned the use of barium salts in its 2018 order due to their toxicity. However, the issue remains complicated. Some manufacturers and even certain scientific formulations have been found to use barium, leading to legal challenges and confusion. As a consumer, the key takeaway is that officially sanctioned 'green crackers' are not supposed to contain barium. Its presence in any firecracker makes it illegal.
Joined Crackers and Noise Limits
Beyond specific chemicals, the regulations also address the physical form and sound levels of firecrackers. The Supreme Court had initially banned 'laris' or joined firecrackers due to the high levels of air and noise pollution they generate in a short amount of time. However, there has been recent consideration for next-generation joined crackers that follow green formulations, burst at a slower rate, and meet noise standards. All legal green crackers must also adhere to a prescribed noise limit, which is generally set around 110-125 decibels, a significant reduction from the ear-splitting bangs of many traditional crackers.
How to Identify Compliant Green Crackers
With many products falsely labelled, how can you ensure you're buying genuine green crackers? The key is to look for official branding. Legitimate green crackers must have the CSIR-NEERI logo printed clearly on the box. More importantly, every box should feature a QR code. When you scan this code with your smartphone, it should lead you to a page that verifies the product's authenticity, including its manufacturing details and certification. If there's no logo or the QR code is fake, it's a major red flag that the product is illegal and likely contains banned chemicals.
