Danu Robotics’ fight to build a better recycling robot

Amy Ma spent years as a software developer at a London bank before a recycling-bin mess changed her career. She noticed that even in a polished office full of money and perks, the building’s separate bins were all being emptied into the trash. Once she started looking, the problem got bigger, not smaller: recycling often still depends on people sorting waste by hand.

That’s the hole Danu Robotics is trying to fill. The Edinburgh, Scotland-based company has spent six years building H.E.R.O., a robot that sorts recycling more cheaply and quickly. It uses a pincer claw rather than a suction system, and Ma says the software improves continuously through AI as the machine learns.

The company says the pitch is starting to land. Danu has letters of interest from two large customers, $500,000 in signed contracts, and more than 200 customers in its sales pipeline. That gives it an opening into a $20 billion market for recycling sorting across Europe and North America. It has also raised $5 million in late-seed funding to push the product into the market.

There’s already competition, including suction-based robotic waste-pickers from Glacier and RecycleEye. But Ma argues the economics make room for a newcomer, because recycling centers earn money from the materials they recover. She estimates a working site could bring in $485,000 in extra revenue, against a $160,000 upfront cost and $24,000 a year in maintenance.

For now, the priority is not flash but durability. Ma wants the robot sturdier, smaller, and more versatile so it can move beyond dedicated waste facilities. If that happens, she sees it being used at events, shopping centers, hospitals, and airports, sorting waste at the source instead of after the fact. Danu Robotics will show up at Startup Battlefield 200 at TechCrunch Disrupt in San Francisco on October 13-15.
