Design Engineer - Loowatt

Location: London, UK
Posted: 3 weeks, 3 days ago


Loowatt has designed and patented a waterless “waste-to-value” sanitation system with current applications as an environmentally friendly alternative to chemical flush toilets and porta loos at outdoor events and construction sites in the United Kingdom and as critical infrastructure in cities globally where access to sanitation is lacking. Loowatt has offices in London, England and Antananarivo, Madagascar with operations in the UK, Madagascar, and The Philippines. In the UK, Loowatt’s toilets serve a variety of applications where the waste is collected and processed in utility-run anaerobic digestion systems to produce power.
