There's nothing that ruins a day out in the park like overflowing bins and rubbish everywhere!
Well maybe these new bins are the answer. They can hold eight times as much as ordinary ones and are powered by energy from the sun.
They also alert the rubbish collectors when they are full on a special website so they can be cleared out.
There are 1,000 of these futuristic bins around Britain at the moment, but they could be on every street sometime soon.
Hayley's been to Cambridge to chat to Dom Coughlan, the owner of the company behind the bins.
