What is waste?

Two young girls taking their rubbish to some recycling bins

In our daily lives, we come across different materials like paper, plastic, metal and food

When we are done using these things, they become waste.

Waste is anything that we throw away because it is broken, old or we simply don't need anymore.

If waste is not disposed of properly, it can end up in our rivers, ocean and land.
