The systematic practice of minimizing resource waste through prevention, efficient use, and material recovery across industrial, commercial, and personal contexts.

Waste Reduction

Waste reduction encompasses the strategies and practices aimed at decreasing the amount of materials that enter the waste stream through preventive actions, efficient resource utilization, and material recovery systems.

Core Principles

Prevention First

The most effective form of waste reduction follows the principle that preventing waste creation is superior to managing waste after it's generated. This aligns with the broader circular economy framework and builds on concepts of resource efficiency.

Hierarchy of Actions

Waste reduction follows a clear hierarchy:

Source reduction (preventing waste creation)
Reuse of materials and products
Recycling and material recovery
Responsible disposal as a last resort
