📖 Syllabus Scope & Overview
Impact of waste accumulation: Air pollution, water pollution, soil degradation, health hazards (epidemics, breeding of vectors like mosquitoes and flies), bio-magnification, and eutrophication of water bodies; Methods of safe waste disposal: 1. Segregation (Biodegradable wet waste vs Non-biodegradable dry waste at source), 2. Open Dumping (hazardous, causes leachate and foul smell), 3. Sanitary Landfills (lined with impermeable clay/plastic to prevent leachate from contaminating groundwater), 4. Composting (organic waste decomposed by microorganisms into humus), 5. Incineration (burning hazardous biomedical/hospital waste at high temperature in incinerators), and 6. The 3 Rs (Reduce, Reuse, Recycle).
