This week I had the pleasure of visiting HomeBiogas to check out their newest accessory: the Bio-Toilet.
The Bio-Toilet connects to the HomeBiogas system, which is an off-grid appliance that turns organic waste into cooking gas. The main appliance- the HomeBiogas system- takes waste such as food scraps and animal manure and using a biological process, turns that into gas.
Now, I hate chemicals and toxins, so when I say biological process I mean that’s 100% a process that is constantly happening in nature all around us. (If you’re interested in more details, look up anaerobic digestion, which is the scientific name for the process that HomeBiogas uses.)
The new Bio-Toilet, therefore, adds human waste (or humanure, as permaculturists may know it as) and uses that as an additional resource to generate the cooking gas.
1. It looks just like a regular toilet, so when the in-laws come to visit, they won’t have to deal with some eco freako situation.
2. It can work either in an outhouse or inside of a home.
3. Once you’ve set up the system, you don’t have to deal with your waste at all. An outlet pipe can connect the effluent directly to a sewage system, septic tank, or a drainage field. In my opinion, dealing with effluent is the biggest shortcoming of standard compost toilets. Like no, I don’t want to drain leachate with my morning cup of coffee, thanks. And let’s just say I’ve had leachette splatter on my face once too many times.
4. You can use grey water to fill up the water in the toilet. This is amazing, because pooping into drinkable water is a shame on western civilization, and is offensive to all those who die from a lack of clean water.
5. It generates energy!!
6. The Bio-Toilet also uses only 1.2 liters of water per flush, as compared to regular toilets which use 7-9 liters of water!
The mechanical hand-pump that fills up water into the toilet does take a few moments of pumping, but I think its important for us to have direct contact with these things, and exert some energy sometimes. Our current household practices where water just magically appears makes us dull to the reality that water is a scarce resource. So I personally don’t mind the pumping at all. For those who aren’t into it, you can also just dump a bucket of water right into the toilet instead.
The system comes stocked with pretty much all the parts of the puzzle; is packaged in two small boxes; and a manual walks you step-by-step through the process of constructing it.
The DIY set up has pros and cons. Pros: it’s a learning experience for both kids and adults. Cons: It’s a good half-day’s work to set it up. Pros: You get to brag to your friends that you set it up all by yourself! Cons: You may have to call up a few friends and bribe them to help you out…
Obviously, this is incredible for refugee camps where sanitation and energy are scarce. But I also think that more “typical western families” should be adopting this type of technology as well. We’re entering an era where our planet just cannot afford to keep going in the linear (extraction -> use -> landfill) method anymore. We just don’t have enough resources to keep digging from the earth and not give anything back. This closed-loop system is exactly representative of the kind of technologies we need to adopt if we’re going to keep living happily on this planet. What’s really great about the Bio-Toilet and the HomeBiogas system is that it makes sustainable living so easy. HomeBiogas have perfected the concept of user-experience. So you don’t need to be an earthy hippy to enjoy their products- they’re made for any type of family.
Final note: I do think this product is better for families than for individuals, because you do need a nice amount of waste to produce a strong and steady flame for cooking. Then again, individuals can also ask their neighbor for some extra food scraps… or they could invite the neighbor to use the Bio-Toilet once in a while.
Cooking food on renewable energy is a unique experience. To know that your meal was made sustainably is exhilarating. Hopefully one day all of our meals will be #renewable.

Read MoreMost people take hot water, indoor plumbing, and flushing toilets for granted, but things aren’t always that easy. Outside centralized sewers, managing waste and wastewater can be a challenge all year round, and having the right equipment can become a game-changer for homeowners. Off-grid toilets and sanitation systems make waste management easier while providing comfort and sustainable solutions. You can pick from multiple systems, from flush toilets to compost toilets to waterless toilets. This blog post will tell you everything you need to know to make an educated decision for your homestead.
Read MoreWhen a household can’t connect to sewage or wishes to live sustainably, composting toilets (or compost toilets) offer homes sustainable, environmentally friendly solutions to human waste management. But selecting the ideal product isn't always straightforward. A bit of research is needed before buying the best composting toilet for your home, and this blog post can help you get started.

But what happens to all the food that is left in the buffet after we're done piling it up on our plates? The hotel industry is responsible for 37% of the food waste in Israel, this is how the environmental and economic damage can be reduced.
