Anaerobic digestion

What Is Anaerobic Digestion?

Anaerobic digestion is a natural way to turn waste into energy. Tiny living things called microorganisms help break down biodegradable material without using oxygen. This process makes a useful gas called biogas, which can be used for power.

How It Works

During anaerobic digestion, the waste changes into biogas and something called digestate. The biogas is rich in a gas called methane, which can light fires or make electricity. The digestate can be used to help plants grow. People use this process in factories, on farms, and even at home.

Where It Happens

Anaerobic digestion happens naturally in places like soil, lakes, and the deep parts of the ocean. It was first discovered by a scientist named Alessandro Volta in 1776 when he found a special gas called marsh gas methane. Today, we use this process to help take care of waste and make clean energy.

Why It Is Important

This process helps us by turning waste into useful energy. It also reduces the amount of waste that ends up in landfills. The digestate left over can be used like fertilizer to help crops grow. Anaerobic digestion is a friendly way to care for our planet and make energy from things we might throw away.
