Mint Innovation, a New Zealand cleantech company, has scaled biological processes that recover valuable metals from waste. The first process is a unique biometallurgical approach to recover metals from electronic scrap. A key aspect of the Mint process is the use of proprietary microbes that are selective for specific metals. Combined with the advantages of low-cost green chemistry, Mint aim to make it viable, both economically and environmentally, to capture value from e-waste near its point of collection.

Enterprise Angels first invested in Mint Innovation in 2018 and it is part of  EA Fund 2.
