There are lots of concepts about waste management which differ in their usage as per the varying regions or countries. Some of the widely used concepts include Waste hierarchy, Extended producer responsibility and Polluter pays principle. The waste hierarchy points to the “reduce, reuse and recycle” that classify waste management strategies as per their effectiveness in regards to waste minimization. The waste hierarchy is the cornerstone of majority of waste minimization strategies. It focuses on taking out the maximum practical advantages from products and generating least amount of waste.

The Extended Producer Responsibility (EPR) is a strategy that is intended for the integration of all costs related with products across their life cycles into the market price of the product. The Polluter Pays Principle suggests that in case of waste leading to any impact on the environment, the polluting party is held responsible and it needs to pays for it.
