Reinvent the toilet: Using hydrothermal carbonization – or simply pressure cooking – to manage faecal sludge

2011 - 2016 • Loughborough University (Water, Engineering & Development Centre, WEDC)

Purpose

The energetically self-sufficient toilet uses an autothermic, hydrothermal carbonising process to produce material that is safe to handle and could be used for soil conditioner.

Activities

Loughborough University is developing a toilet that transforms faeces into a highly energetic combustible material. The schools/departments contributing to the project include: Water, Engineering & Development Centre, (WEDC), Chemical Engineering, Design, Materials, Civil and Building Engineering, Chemistry, Mechanical and Manufacturing, and Systems.

The new toilet uses an autothermic, hydrothermal carbonising process to produce material that is safe to handle and could be used for soil conditioner. In parallel with our engineering development we are designing the system to suppress smells and provide users with a positive and comfortable experience. The system is designed to be self-sufficient in terms of energy input, is cost efficient and will work for a single family or community.

The Water, Engineering and Development Centre is one of the world’s leading education and research institutes for developing knowledge and capacity in water and sanitation for sustainable development and emergency relief. We focus on solutions for people in low- and middle-income countries, helping to provide evidence-based answers to important questions – not only about what needs to be done to improve basic infrastructure and essential services – but also how to go about it. Founded in 1971, WEDC is based in the School of Civil and Building Engineering at Loughborough University, one of the top award-winning UK universities.

Projects

The project database contains nearly 400 sanitation projects of many different organizations dealing with research, implementation, advocacy, capacity development etc. Advanced filtering functions and a global map are also available. Information on how and why this database was created is here.

People working for SuSanA partners can add their own projects through their partner profile page. You might need your SuSanA login upgraded for this purpose. Please contact us if you would like to add a project.
