We are a team from North Carolina State University passionate about developing and bringing to market the best pit-latrine emptying device to billions of people. We made the first version of the Excluder in 2011 with funding from the Bill and Melinda Gates Foundation. Since then, more than four iterations of the design have been tested with support from our partners in South Africa, Malawi, India, Zambia and Kenya. Our most recent phase of development began in September 2017 and includes a partnership with Catapult Design and Triangle Environmental Health Initiative to bring the prototype machine to several target countries and establish markets for entry.

We received the 2020 USPTO Patents for Humanity Award and the Grand Prize for the 2018 RELX Environmental Challenge
