Waste Management: An Overview
Types of Waste

Waste Management Methods
1- Reduce, Reuse, Recycle (3Rs)
Reduce: Minimize waste production.
Reuse: Extend product life by repurposing.
Recycle: Convert waste into new products.
2- Landfilling
Waste is buried in designated landfill sites.
Modern landfills use protective liners to prevent pollution.
3- Incineration (Waste-to-Energy)
Waste is burned at high temperatures to generate energy.
Reduces landfill use but may release pollutants.
4- Composting
Organic waste is decomposed into nutrient-rich compost for agriculture.
Environmentally friendly and promotes soil health.
5- Biogas Production
Organic waste is processed to produce methane gas for energy use.
Reduces reliance on fossil fuels.
6- E-Waste Recycling
Recovering valuable metals and materials from electronic devices.
Prevents toxic heavy metals from contaminating the environment.
