Sludge to resource workshop feedback

The past two weeks have been busy in the best way, but it means I’m behind on writing how it all fits together.

I attended a Sludge to Resource workshop in Durban, 23 – 24 October 2018. My write-up is available here (word doc) and I hope to pull some highlights into the post itself in due course. Some info, with some schedule changes: http://wisa.org.za/event/sludge-to-resource-symposium/
