Waste management concepts

Believe it or not recycling is not top priority whne it come sto waste management methods.

Most favoured options are  prevention and minimisation (greener options at the top), then comes reuse and recycling, whereas energy recovery and disposal come last (red options at the bottom).

There are a number of concepts about waste managementwhich vary in their usage between countries or regions. Some of the most general, widely used concepts include:

  • Waste hierarchy – The waste hierarchy refers to the “3 Rs” reduce, reuse and recycle, which classify waste management strategies according to their desirability in terms of waste minimization. The waste hierarchy remains the cornerstone of most waste minimization strategies. The aim of the waste hierarchy is to extract the maximum practical benefits from products and to generate the minimum amount of waste see: resource recovery.
  • Polluter pays principle – the Polluter Pays Principle is a principle where the polluting party pays for the impact caused to the environment. With respect to waste management, this generally refers to the requirement for a waste generator to pay for appropriate disposal of the waste.
