The environment is one of the central elements in the sustainable development of the country, and India is one of the global leaders in the adoption of environment-friendly measures by enacting stringent environmental legislation and has created institutions to monitor and enforce legislation. However, the concept is gaining prominence, especially with the Indian waste management industry offering huge potential.

Only 30% of the 75% recyclable waste is currently being recycled
