There are two types of wastes:
Biodegradable waste- The waste which can decompose in nature to form harmless substances is called biodegradable waste. All the garbage from plants such as fruits and vegetable peels, leaves, paper, jute, cotton etc. and from animals such as wool, silk, leather and cow dung etc. Biodegradable garbage is also known as organic waste.
Non-biodegradable waste – The waste which does not decompose in nature is called non-biodegradable waste. The garbage which consists of plastics, glass and metal objects is non-biodegradable. Getting rid of non-biodegradable part of garbage is a problem because it does not decay when buried and some of it gives poisonous gases when burned.
