Project description

From your toilet to the garden

Don’t take your toilet for granted! So much has changed since the first ones made their debut in the 1800s. From the high-tank toilets that ruled during the Victorian era to the modern marvels we are used to today, there’s one thing that has not changed: water usage. Did you know that toilet flushing accounts for about a third of household water usage? While dry toilets may be part of the solution, they are not designed for city residential blocks. The EU-funded SANIBUILDING project will develop a unique method designed specifically for storey buildings. Using small amounts of water and electricity, this new technology will be capable of transforming faeces into high-quality compost used for gardening.


Today, sanitation systems at western countries are based on flushing toilets and its subsequent treatment of waste waters. This method implies a huge amount of water used per person as well as a lot of energy that is used for waste water treatment plants. This method does not always comply with the standards, polluting soils and watercourses. On top, the extension of Europe dry regions could increase to 26% if the average temperature rises 2 degrees Celsius. New flushing toilets incorporating less litres at their tank still don’t solve the problem. For the reasons expressed above, new approaches of feces and urine management at urban level need to be considered in order to ensure natural areas’ preservation, improve water/energy management and reduce its consumption. Dry toilets are a part of the solution, but most of them are conceived for individual houses or isolated cabins but not for storey buildings. In response, SANISPHERE, a French SME leader at dry toilets with a patented urine and feces separation system and composting method based on earthworms created SANIBUILDING, an unique method able to be used at storey buildings no matter the number of storey, with a negligible use of water and electricity with the possibility to transform feces in high quality compost used for gardening, with a very easy maintenance. SANIBUILDING project aims to finalise now its technical development and market preparation. To achieve these objectives first we need to prepare a Feasibility Study that help us warrant our project from all technical, financial and commercial points of view. This study will allow us to set the plan to push our technology forward, from TRL6 to TRL9. Once completed, this project will bring key advantages to society and the environment while boosting the growth of our company. Indeed, we estimate to gain €5.7 million in profits and reach a ROI of €3 from this project after 5 years, with a positive impact regarding employments with 31 job creation.
