I created a class called Water and Sanitation: Design and Practice with inspiration from Ethiopian faculty colleagues because so much of what is needed in water treatment for majority of the world is not in our conventional textbooks, across Global South and North. Almost to the end of the term. For tomorrow's topic, we start Ecosanitation and will focus on #peecycling and circular economy - for those new to this: it is about recovering N and P elements from wastes in concentrated forms by separating at the point of excretion, and using technology to process to safe NPK fertilizers. Last topic after this will be science communication & environmental justice, a topic in great demand by students. Happy to connect with anyone else creating similar content in their courses.
