Waste Management
Wastes are substances that are formed as a result of human activities and cannot be used directly. These substances, which have the potential to harm the environment, can cause the ecological balance to deteriorate and endanger human health when not managed with appropriate methods.
Solid wastes are divided into two main groups:
- Harmful Wastes: These are wastes that may harm human health and the environment and must be disposed of with special processes. These can be toxic, flammable, or have corrosive properties. For example, chemical wastes, batteries, medical wastes fall into this group.
- Harmless Wastes: It consists of organic and inorganic substances that do not directly harm the environment and human health. Domestic and natural waste is in this category.

There are six types of solid waste according to their source:
-
Domestic Waste
Organic and inorganic garbage, ashes, old furniture, etc. -
Industrial Waste
Metal, plastic, chemical and production residues from industrial facilities. -
Commercial and Institutional Waste
Waste from offices, schools, restaurants, and stores. -
Municipal Waste
Waste collected from street cleaning, parks and gardens. -
Special Waste
Wastes that contain hazardous components and require special disposal (e.g. paint, batteries, medical wastes). -
Agricultural Wastes
Organic wastes, fertilizers and animal wastes from agricultural activities.
