This year’s BlueTech Forum in San Francisco on 1st June brought together industry leaders, entrepreneurs, innovators, end-users and investors for a dynamic day of thought-provoking discussion and learning. There were three main sections: 1) innovation showcase company roundtables – water technology briefings where selected firms presented new developments and case studies; 2) roundtables where views were exchanged on specific technology issues such as nutrients and brine management; 3) thought-leadership panels where wider industry topics from corporate water risk to the future of decentralised water treatment were discussed. Here we present a brief round-up of the some of the main points raised and key takeaways.
