- Biofuels
- Can be made by fermentation...
- ...of natural products
- Fermentation is when bacteria or yeast break sugars down by anaerobic respiration.
- Ethanol made by Anaerobic Fermentation of Sugar
- Yeast make ethanol when they break down glucose by Anaerobic Respiration.
- The Ethanol is distilled to separate it from the yeast and remaining glucose
- Yeast make ethanol when they break down glucose by Anaerobic Respiration.
- Biogas is made Anaerobic Fermentation of waste material
- Biogas is usually 70% methane and 30% carbon dioxide
- Lots of different microorganisms are used to produce biogas
- Can't be stored as a liquid as it needs to be a high pressure, so it has to be used straight away

- Biogas is usually 70% methane and 30% carbon dioxide
- Fuel production can happen on a large or small scale
- Large-scale generators are now being set up.
- Human waste, waste from keeping pigs and food waste can be digested by bacteria to produce biogas
- By products are used to fertilse crops and gardens.
