🟢 India's Plastic Footprint & Statistics
• India accounts for more than 6.5% of global plastic consumption.
• While official figures estimate 4.1 million metric tonnes of annual plastic waste, the Central Pollution Control Board (CPCB) reveals that India actually generates 26,000 tonnes daily, culminating in 9.5 million tonnes per year.
• The bulk of this waste comes from cities and suburbs, leaving substantial rural waste largely uncollected.
• Unlike Australia and Canada, which use plastic for banknotes, India retains paper currency but utilizes plastics extensively for credit cards, PAN, and Aadhaar cards.
🟢 Recycling & Waste-to-Energy Solutions
• Organizations like the Plastics-India Foundation promote recycling discarded plastics into medically safe bottles, while plastics like Teflon and Nylon are repurposed for consumer goods packaging.
• Through a high-heat process called pyrolysis, plastic waste is being effectively transformed into useful fuels.
• Technologist P. Sahasrabuddhe in Pune and a dedicated firm in Hyderabad have successfully generated cooking gas (such as 'Vaayu') from domestic and plastic waste.
• Highlighting regional success, a waste-to-energy plant in Karnataka currently generates electricity by burning garbage sourced from Bengaluru.
🟢Advancements in Hydrogen Production
• Plastic waste can produce hydrogen gas, which generates clean electricity when oxidized.
• Researchers at the University of California, Los Angeles (UCLA) recently demonstrated hydrogen production from plastic waste using heat and atmospheric carbon dioxide.
• Concurrently, the CSIR-Indian Institute of Chemical Technology in Hyderabad produces hydrogen from seawater via catalysts, and Columbia University generates it from seaweed biomass.
• Scaling these innovations, the Indian Railways recently demonstrated long-distance services running on hydrogen instead of coal, and a nuclear plant in Kalpakkam (Tamil Nadu) produces hydrogen gas by heating copper chloride.
