Biodegradable

Reuse

Using items more than once instead of throwing them away, such as using glass jars for storage.

Recycle

The process of collecting and processing waste materials to change them into new products.

Waste

Any material or object that is no longer needed.

Organic Waste

Composting

The process of turning organic waste, like fruit peels and vegetable scraps, into compost to help plants grow.

E-Waste
