Pollution is not a distant threat — it is a daily reality. This is the problem we set out to solve, and why we decided a machine had to do it.

tonnes of plastic waste are found around the earth each year — every single year.

Organic waste decays and returns to the soil. These materials do not — they only get smaller, spread wider, and stay.
Plastics
Bottles, bags, wrappers and packaging do not biodegrade. Sunlight and abrasion only break them into smaller and smaller fragments, which spread further than the original object ever would.
Foam and polystyrene
Extremely light and easily carried by wind and water. It crumbles into small beads that scatter across a wide area, which makes collecting it by hand almost impossible.
Synthetic textiles
Clothing made from synthetic fibre sheds microfibres. Once loose in the environment, those fibres are far too small for any manual cleanup to recover.
Metal and glass
Chemically inert but physically persistent, and sharp when broken. This is the waste that makes hand-collection genuinely hazardous for volunteers.
Cleanup drives matter, and the people who run them matter. But the arithmetic does not work in their favour.
Coverage never matches volume
A cleanup drive clears one area on one day. Waste keeps arriving every other day, across every other area, and the gap only widens.
Cost scales with people
Every additional square metre of coverage needs additional hands. The cost of cleanup rises in step with the area, so it never gets cheaper with scale.
The work is repetitive
Spot an object, walk to it, pick it up, repeat. It is exactly the kind of task where human attention fades and a machine does not.
Handling waste is hazardous
Broken glass, sharp metal and contaminated material make manual collection risky, which limits who can safely take part.
Cleanups are episodic
Pollution is continuous but cleanup is occasional. Anything that only runs when people are available will always be behind.
“What if we create something that automatically does this for us, without the need for human involvement?”
The question that started the project
Every decision on the robot gets measured against these.
Autonomy first
If it needs someone standing over it, it does not solve the scaling problem. The robot has to decide and act on its own.
Built to be affordable
A cleanup machine only matters if it can be reproduced. Cost is a design constraint, not an afterthought.
Continuous, not occasional
Pollution arrives every day, so cleanup should run every day rather than waiting for an organised event.
Safe to be around
It works in shared public spaces, so it has to behave predictably around people going about their day.
