Waste Disposal Methods
- Recycling
- Advantages: Conserves resources, reduces environmental impact, and produces new materials.
- Disadvantages: Expensive, challenging to separate useful materials from waste, and not all waste is recyclable.
- Waste Incineration
- Advantages: Reduces waste volume by approximately half, doesn’t require large land areas, and can be carried out in any weather.
- Disadvantages: Requires skilled specialists and produces unpleasant odors.
- Sanitary Landfill
- Involves systematic waste burial, requiring detailed planning, design, operation, and ongoing maintenance to minimize environmental impact.
Types of Waste
- Liquid Waste
- Examples: Household wastewater, industrial detergents, and chemicals.
- Solid Waste

Waste Management
Definition:
The process of handling discarded materials to mitigate their potential hazards and convert them into useful products through methods like recycling, composting, or landfilling.
Goals of Waste Management:
- Protect individuals and the environment from harmful waste effects.
- Reduce health risks associated with improper waste disposal.
- Promote sustainability by reusing or safely disposing of waste materials.
Example of Waste Hazard:
- Engine oil contamination: Just 3.75 liters of engine oil can pollute up to 3,790,000 liters of drinking water, highlighting the importance of proper disposal practices.
Effective waste management ensures the safety of ecosystems, conserves resources, and promotes a sustainable environment.
