How many main components are there in integrated waste management? 

The integrated waste management plan is the plan generally made for the disposal of solid waste.  

This plan has three key components:

1. Source Reduction: 

• ​It involves reducing the amount and toxicity of the wastes produced.  
• It is the most effective way to reduce the quantity of waste & also the cost associated with its handling, and its environmental impacts.

1. Recycling: 

• It helps to reduce the demand for resources and the amount of waste requiring disposal by landfilling. It involves the following:

1.  The separation and sorting of waste materials.
2.  The preparation of sorted-out materials for reuse or reprocessing.

3. Disposal: 

• ​It involves the alteration of wastes to recover conversion products like compost and energy.
• The processing of waste materials usually results in the reduced use of landfill capacity.
