Waste Treatment

Waste treatment encompasses the various technological and biological processes used to handle, process, and dispose of waste materials generated by human activities. This fundamental aspect of environmental management aims to protect public health and ecological systems while increasingly focusing on resource recovery.

Core Principles

The primary objectives of waste treatment include:

• Reducing environmental hazards
• Minimizing public health risks
• Recovering valuable resources
• Meeting regulatory requirements
• Supporting circular economy initiatives

Major Categories

Municipal Solid Waste Treatment

• landfill disposal method in many regions
• waste sorting and material recovery
• incineration with energy recovery
• composting of organic materials
