Danu Robotics, a six-year-old Edinburgh startup, is bringing its recycling-sorting robot to market after years of development. Founder Amy Ma says she was inspired to act after seeing office recycling bins at a London bank emptied into the trash. The company's robot, called H.E.R.O., uses a pincer claw instead of the suction systems common on competitor machines from firms like Glacier and RecycleEye.

Danu says it has $500,000 in signed contracts and letters of interest from two large customers, with more than 200 prospects in its pipeline. The company has raised $5 million in late-seed funding. Ma argues the economics are compelling: she estimates a working site would earn $485,000 in additional revenue from the robot, against a $160,000 initial investment and $24,000 in yearly maintenance.

The source notes that Danu's differentiator is its business approach as much as its hardware: the company uses AI to keep improving the robot's software after deployment. Ma's next goal is to make the unit smaller and portable enough for use at events, shopping centers, hospitals, and airports, allowing waste to be sorted at the source. Danu is set to appear at TechCrunch Disrupt's Startup Battlefield 200 in San Francisco in October.
