Unlike celebrations in previous years, this year’s Diwali will have an interdiction of usage of fireworks. In addition as mentioned yesterday, firecrackers that have reduced emissions and are of the category of “green crackers” can only be manufactured and used.
Director of the Council of Scientific & Industrial Research (CSIR) National Environmental Engineering Research Institute explained that the firecrackers that are permitted are called green crackers as they are void of harmful chemicals that lead to air pollution. The composition of regular firecrackers are altered to create crackers that are less dangerous to the environment.
Those responsible for this innovative idea include Science & Technology Minister Harsh Vardhan who introduced it, Central Electro Chemical Research Institute (CECRI), Indian Institute of Chemical Technology, National Botanical Research Institute and National Chemical Laboratory which were labs of the CSIR who were responsible for bringing the thought to reality.
The CSIR-CECRI was instrumental in developing eco friendly products that include flower pots of that nature which can limit particulate matter by 40%. The institution is also its testing stage for bijli crackers which is intended to eliminate use of ash as desiccants.
Crackers of such innovative nature are named Safe Water Releaser (SWAS), Safe Thermite Cracker (STAR) and Safe Minimal Aluminium (SAFAL). What is special about these products is that there is a release of water vapour and/or air as dust suppressant and diluent for gaseous emissions and thus matching its performance in terms of sound in comparison to conventional crackers. These crackers are being tested for its safety by the Petroleum and Explosives Safety Organisation.
