Hempcrete

cartoon boy

The hemp is used to make a type of concrete called hempcrete. It uses the tough, stringy fibres from the hemp plant stems. It needs less energy to make it than normal bricks or concrete. That's good for the environment.

When the hemp plant grows it takes in carbon dioxide. This means that when the bricks are made, the carbon becomes part of them, and is not released into the air.

Hemp does not even need lots of fertiliser to grow.

Watch this short film about making and using hemp.

But how much do you need for a whole house?
