Danu Robotics’ fight to build a better recycling robot

For six years, Danu founder Amy Ma has been working on a better way to sort recyclable waste. For Danu Robotics founder Amy Ma, the eureka moment came after years of working as a software developer at a London bank. It was the kind of high-touch office that’s typical in finance — but despite all the perks, Ma was alarmed to realize that the building’s recycling bins were being emptied into the trash. “Even though they have tons of money, there’s all these different recycling bins that just end up in the same place,” Ma told TechCrunch. The more she dug into the problem, the deeper it seemed to go. It wasn’t just her building.

The economics of recycling as a whole often boil down to human beings sorting by hand through streams of waste to pull out different kinds of recyclable material. “I saw the technology and thought, we can do so much better,” Ma remembers. Now, she’s making good on that promise with six-year-old, Edinburgh, Scotland-based Danu Robotics, which makes a robot designed to sort through recycling more cheaply and quickly. Ma has been working on that idea for six years and is finally bringing her version of the product to market. Her robot, dubbed H.E.R.O., has a few advantages over its competitors. For example, it picks up
