Imagine being able to cook with the energy that comes from your lunch leftovers. Yes, it sounds strange, we know, but it is already possible and maybe the future.

It is called HomeBiogas 2.0 and it converts food waste into gas and natural fertilizer, generating clean energy from what you would normally throw away.

It can produce up to 4.4 kWh and 53 gallons of gas per day, enough to cook or heat water for a shower! And without depending on the traditional supply, lower electricity bills, much less waste, and a much more sustainable home!

How it works

It is basically a “mini power plant” for your backyard. You throw in your organic waste (fruit peels, food scraps, vegetables…), and inside, the matter decomposes without oxygen and generates clean biogas and liquid fertilizer. It is ideal because it is a closed, ecological, and safe system.

Each day it can process about 4 liters of food and 4 of water, and the gas it generates is stored in a 700-liter tank, which provides around two hours of free cooking per day.

And it produces about 8 liters of liquid fertilizer that you can use for your plants or garden. So even your tomatoes benefit.

Designed for the home

You don’t need to be an engineer to use it, just have space. It is two meters long and a bit more than one meter wide and tall, so it fits in a garden or a large terrace.

However, it needs a mild environment (around 20°C or more) to work properly. If you live in a cold area, you might need a small heating system to help it.

It costs around 1,380 dollars, but it pays for itself in a short time thanks to the monthly savings on gas and electricity. It is already installed in more than 70 countries (from Kenya to Puerto Rico and Spain), which proves that this idea works in very different climates and contexts.

Less waste

Surely at some point you have wanted to make compost for your garden, but now you can make compost while also reducing your electricity bill. Maybe it’s not much, but you can get up to 130 kWh of energy per month just by reducing your organic waste, it sounds like a good saving to us, what about you?

Plus, you save on electricity, reduce waste, and also lower methane emissions, so you are helping take care of the planet. Who would have thought that the spaghetti and stew you didn’t finish could become the energy that powers your washing machine?

Circular energy and energy freedom

The great thing about this invention is that it gives you a bit of energy independence, you won’t depend so much on the power grid or natural gas. It is your energy, and you decide how to use it.

We like it even more now that prices keep going up and electricity bills are often impossible to pay. The world needs a break, and so does your bank account, so any solution like this seems like a good option.

Also, you don’t need to be an engineer or a big company to want to reduce your home energy costs a little!

Goodbye to bills

It doesn’t mean you’ll suddenly be 100% green, but waste is waste, and now it can lower your bill a little. We like sustainability, and we like paying less!

Could it be that the green revolution starts in every home, using our own waste?
