Write about the 3R technology in waste management.

We can follow the 3R approach - reduce, reuse and recycle - for effective waste management.

Reduce: One can reduce the amount of solid waste at the source itself. Example: Use of less paper and less plastic carry bags.

Reuse: One can use plastic bottles and jars, aluminium foils and plastic bags over and over again, before recycling or disposing them of.

Recycle: Used and discarded materials like plastic, glass, paper and metal are sent to the respective industries, where they can be converted into other useful products.
