Periodic Reporting for period 1 - SANIBUILDING (INNOVATIVE AND DISRUPTIVE DRY-VERMICOMPOSTING TOILET CONCEIVED FOR EU STOREYS BUILDINGS)

Reporting period: 2018-11-01 to 2019-02-28

Summary of the context and overall objectives of the project

The generalization of flush toilets in the 19th century, together with the growth of sewage systems, significantly improved the health of human urban populations. However, these systems came at a huge environmental cost: they pollute large amounts of clean water in a lengthy and energy-intensive process. At Sanisphère we believe it is time for the next great transition in human waste treatment, using on-site waterless vermicomposting of faecal matter. Commonly used in Scandinavian countries, composting toilets have been spreading to the rest of Europe and the US as a solution for remote areas without sewage systems. Indeed, this has been the base of Sanisphère's business model since 1991, installing over 600 stand-alone public toilets in Europe and Canada. However, current systems cannot be installed in multi-storey buildings without a limit on height, and the volume of the composted final product is considerably large, hindering adoption in cities. With Sanibuilding, we have a designed a system capable of overcoming these limitations. Firstly, we will use worms to accelerate the composting process, reducing the volume of the final material. Secondly, we will use several technical innovations including our patented urine and faeces separation device, a large, slow conveyor belt to support the composting process, and a passive ventilation system assuring the absence of odours

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

Our technical feasibility study has shown that it will be possible to integrate these components into a multi-storey building, however, further technical work is needed to reduce manufacturing costs. In addition, experimental work to assure the sanitary and agronomic qualities of the compost needs to be carried out. In order to achieve these objectives, Sanisphère will require collaboration with other companies with relevant expertise. Commercially, we will thus focus on populations with an already strong environmental motivation, willing to pay more for sustainable products. Our market study has shown that public institutions and housing cooperatives are ideal candidates, already seeking greener building solutions.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

The launching of Sanibuilding could trigger a key cultural shift towards sustainability in large cities, and would greatly impact our company. Our target markets would significantly expand, allowing us to grow with 7 new employees in 5 years, and obtaining an ROI of 1.4 over that period.
