Technological innovation in environmental mitigation: a relevant GS3 Science & Technology topic.

Why in news

Scientists at the Council of Scientific and Industrial Research (CSIR) have developed second-generation green crackers to significantly reduce air pollution emissions.

Background

Dr Sadhana Rayalu and CSIR scientists developed green crackers following a 2017 challenge by Dr Harsh Vardhan. While first-generation crackers reduced particulate matter by 30%, the new second-generation formulations achieve 45 to 60 per cent emission reductions.
