Chandigarh, India, has officially launched a four-bin waste segregation system as part of the revised Solid Waste Management Rules, 2026. Residents are now required to separate their waste into four categories: wet waste in green bins, dry waste in blue, sanitary waste in red, and hazardous waste in black. This initiative, effective since April 1, aims to promote scientific disposal practices and enhance environmental protection. Municipal commissioner Amit Kumar emphasized the importance of strict adherence to these guidelines, stating that violators could face penalties of up to ₹14,000. The new system addresses previous shortcomings in waste segregation and aims to improve Chandigarh's performance in national cleanliness rankings. Additionally, bulk waste generators, such as housing societies and commercial establishments, are mandated to process wet waste at the source. The civic body has urged residents to cooperate in these efforts to ensure effective waste management.
