Plastic waste is choking our waterways and harbors. Eight million tons end up in our oceans each year, killing wildlife and poisoning the food supply. A lasting solution will require bold policy innovations, industrial curbs and lifestyle changes. Meanwhile, there’s an urgent need for clean-up efforts. BluePhin Technologies developed six prototype robots that, when deployed, pull plastic waste out of the ocean. Now, founder Simran Chowdhry is adapting the robots’ waste-detection algorithm to be able to filter out liquid waste like oil and algae. Chowdhry speaks with Bloomberg New Economy Managing Editor Katheryn Glass. (Source: Bloomberg)
