Marvellous microbes

Microbes have an important role to play in making biogas, a good source of renewable energy. This video explains how microbes convert kitchen waste into biogas, and how the process improves the lives of people in Bangladesh.

Helping improve health by getting rid of waste, and using biogas as a fuel for cooking is a good example of  technology justice in action. Technology justice is about making sure everybody has access to the technology that is essential for life. For other examples of #techjustice in action please also take a look at these videos:

Beat the flood  Investigating the properties of materials used to build a flood-proof house
Pump it up!  Explaining the science behind how a water pump works. 

To explore technology justice further with your pupils please look at our technology justice activities
