Modern technology is increasingly becoming part of our daily lives. For example, dacha owners or owners of private homes everywhere are beginning to abandon the traditional pit latrines in favor of so-called biotoilets. This is not surprising, because this equipment does not need any sewage equipment, does not require connection to other utilities.
Due to the fact that in the wide sale of such devices appeared not too long ago, not all users know how to properly proceed to the selection of similar products. Exactly for them we decided to make a rating of the best bio-toilets of the year. In today’s article, we will consider in detail the useful characteristics of the most popular models on the market, as well as give a number of key rules, based on which you should buy these products. Let us begin with it.
How to choose the optimal bio-toilet?
All similar structures are divided into three main groups – liquid, peat and electric. They differ from each other by principle of functioning, as well as some operational features. Liquid devices are characterized by their compact size and the presence of a sealed container. Depending on the liquid used, they can be formaldehyde, ammonium and bacterial. Formaldehyde compounds are one of the cheapest bio-toilets on the market, but they use quite poisonous liquid. Pour the waste directly from such a device on the site or near water bodies is strictly prohibited, so the way of disposal must be thought out in advance.
Ammonium are safer, the liquid they contain will independently decompose into harmless compounds for about a week. Bacterial bio-toilets are the most environmentally friendly. They contain colonies of active bacteria, so the waste from the toilet can be later used as fertilizer on the site. Liquid bio-toilet consists of two main elements: a toilet bowl and a storage tank, where the waste will be broken down without releasing gas. These designs are compact and hermetically sealed.
In the peat bio-toilet the waste is processed by the bacteria contained in the peat. There is a special dispenser, where consumable material is poured. If necessary, it will evenly cover the waste. It is desirable to install such a structure in a separate room or a special annex, because it will need to be equipped with an exhaust pipe. The mixture is consumed efficiently and economically. Waste does not become toxic after processing; therefore it can be added to humus or compost.
It is most convenient to use electric bio-toilets, but you need to think beforehand where and how they will be connected to the network. These models are equipped with a fan and compressor. The solid and liquid fractions are separated in the storage tank. Liquid waste is discharged through a hose, and solid waste is thoroughly dried to a powdery state and goes to a collection container. It is worth noting that these models are the most expensive. It is desirable that any composting toilet is equipped with a display of the tank’s filling. Pay attention to the volume of the storage tank and dimensions of products.
When we chose models for inclusion in our rating, we were mainly guided by all the principles discussed above, but also took into account the price/quality ratio and user feedback. We tried to include not the most expensive models so that each of our readers could choose the most suitable product.

Compost type filler is poured into the bin where the sewage arrives and a special humus catalyst is added. These are mixed thoroughly until they reach a homogeneous mixture, where they immediately activate the decomposition processes. The engine starts when the faeces enter and mixes it with the compost, ensuring constant access of oxygen. The lower part of the tank, where the waste is processed, is a grid through which the dry humus is poured into a tray. Recycled waste can be poured into the composting box.
