Biogas is a type of natural gas. It is created by breaking down the bacteria in organic waste (such as plant and animal products) in ‘anaerobic digestion’ – a digestive process in a purpose-built vessel, and an oxygen-free environment.
When creating biogas from food waste, the biogas is created by anaerobic digestion, recycling the organic material fed into the vessel which releases biogas.
But that’s not all: the biogas from the food waste process separates the energy created – the biogas itself – and any other solid run-off (‘digestate’), which can also be used for sustainable living.
This anaerobic digestion process can happen naturally in some landfills, natural environments and even livestock manure processing factories, but not at any significant, environment-changing level. For that, we need to look at making longer-lasting and higher-impacting changes.
One of these could be harnessing the power of the anaerobic digestion process to produce biogas from food waste. It’s an optimized, controlled process, and has the power to make a huge impact on your personal contribution to landfills, while cutting down the amount of food waste you produce, and even saving your energy bills!
In Elumalai polytechnic college campus hostel such kind of biogas system has been implemented for creating biogas to be used for cooking in the hostel.It is similar to a process of recycling the kitchen waste from the Polytechnic hostel’s kitchen into another form of energy that is gas used for same Hostel cooking.
CREATING BIOGAS FROM FOOD WASTE
The HomeBiogas reactor brings you the ability to create your own biogas from food waste to your own home. Installing the reactor takes no time at all, and brings you an all-natural, environmentally-friendly way to cook your food and fertilize your garden.
In Elumalai Polytechnic about up to 6 liters of food scraps (or other organic waste) are put into the system.Which in turn is collected as gas to the stove, and we start cooking.
In the Polytechnic campus hostel the biogas is formed from the food waste,kitchen waste(vegetable).The formed gas is collected through a pipe and intern sent as fuel to the stove,so food can be cooked.
It’s odor-less, hassle-free…and gives you all the benefits outlined above.
You can feed the HomeBiogas system anything from fruit, dairy, eggs, meats, cooking oil and more that’s organic.In Elumalai polytechnic College hostel food waste are collected and it is the raw feed for creating biogas. The system itself is a one-time purchase that will last you up to 15 years before you need to replace it. Even better, it doesn’t require any cleaning (which makes it the best type of composter or stovetop you could ask for).
