There are so many ways to turn food waste into energy, and many people have been looking for more effective ways to do this. With the costs of fuel rising to new highs, why don’t you use that waste to help your family get cleaner air and save money?

If you’re buying or building your new home, make sure you have a list of everything that you’ll need, and one of them is a water heater. While most of us think about heating water for our home, in reality, many things could be heating water. Whether it’s a pool, a hot tub, or a water heater, you can reuse it to heat your home and save you money.

If you find yourself using hot water for your hot tub, you know how much you’re wasting. Unconsciously, you may not realize is that all of the hot water that’s wasted is not going to the hot tub, but it’s going straight from the water heater to your hot tub. You will also notice that your hot tub is not as clean as it once was. This is because most hot tubs are not designed to handle this waste, and you need to clean it every so often.

In fact, many people who are not planning on ever installing a water heater are just throwing out the water they’ve been using in the tub for a very long time. 

Aside from eliminating your food waste, you can turn them into energy to heat your water, and here’s how:

1. Autolysis

The process of simply decomposing the waste in the water is called autolysis. The energy you’ll generate is great for the environment, and your family will love the water you have to drink.

You can use autolysis to recycle all kinds of unwanted waste. In the case of food waste, it breaks down, and its component chemicals break down into simpler compounds. The simplest form is methane gas. When these gases escape into the atmosphere, the gas mixture becomes very hot and toxic, making it difficult to capture. However, when an enzyme is used, a heat exchanger kicks in and converts the heat into energy, which then is used to heat a chamber containing water and food waste.

Then, you can get the autolysis system used for a water heater, or you can use a cheaper alternative to it that’s a combination of autolysis and heat exchange. You’ll also need the right plumbing to get it done properly and make sure you get all of the pipes and fittings done correctly.

2. Use Heat Exchanger

A better alternative for autolysis is a heat exchanger, which allows you to use the waste from the water heater to heat your water. The rest of the water in the water tank is heated to a different temperature. That way, you can drink the water at whatever level you desire. You can even change the water level as you need to. If you live in an apartment, you can still use your water heater for your drinking needs.

Moreover, as the food is processed, it breaks down and turns into a solid that you can use in other ways. This waste is usually fertilizer, which can be put in the garden or used in composting.

3. Filtration Process

Lastly, you’ll need a filtration system in place to remove any excess waste from your pipes. This is usually not as hard as you might think since many of these systems are very inexpensive and easy to install.

If you need a new a water heater, you can save some money with the autolytic system. Since it has already been installed, there’ll be no extra costs to install anything new and add an autolytic system. If you don’t have a water heater, you can always put in a heat exchanger and use it for your drinking water.


There are many other options for heating water using your food waste by turning it to energy. If you’re not living in a big home, then using your existing water heater is a great way to turn food waste into energy. You might even combine these methods to create both water heating and heat to power your house for free.

By doing so, you can decrease food waste disposal while saving money from heating water.
