Australians love cooking with gas, but what if you could make your own supply, using leftover food waste? It may be time for more households to embrace home biogas – and stop paying gas bills.

In practical terms, I put in about 2kg of food waste each day and so far I have had enough gas to cook with, sometimes twice a day. If I ever needed more gas, I could put in more organic matter. I will continue to monitor the system as part of my research and will publish updates in due course. If interested, watch this space.
