David is a recognised circular economy expert, having been involved in resource and waste management policy making at local, regional and government levels in his early career, to developing circular economy businesses such as SOENECS and Tech-Takeback, that demonstrate the possibilities of circularity in the last decade.

The Venture studio teams builds early-stage businesses, develops ground-breaking resource and material technology, and creates commercially valuable intellectual property.
