19. Waste Generation and Management

Waste generation is the result of human activities producing unwanted materials and managing this waste is crucial for environmental and public health. Various types of waste exist, including biodegradable, non-biodegradable, and hazardous waste, each originating from distinct sources such as households, industries, and medical facilities. Improper waste management leads to pollution, disease spread, and ecological harm, making effective recycling, composting, and community involvement critical.
