“The Interceptor is an autonomous solar-powered device that uses a barrier stretching across a river to collect plastic. Rubbish is funnelled towards a floating processing plant that resembles a barge. The trash is passed up a conveyor belt and deposited into bins, which signal to the system when they are full so that a boat can come and pick them up for recycling.”
“The Bubble Barrier is a perforated tube laid across the bottom of the canal with compressed air pushed through it. It runs 24 hours a day, seven days a week, forming a screen that catches floating debris.”
“Mr. Trash Wheel, an anthropomorphic trash interceptor with googly eyes and his own Twitteraccount, has been scooping rubbish out of the Jones Fall River in Baltimore since 2014.”
“Using technology New Naval developed for responding to oil spills, the mesh barriers collect river plastic and channels it towards a floating cage. This is used to lift the plastic up to the level of the harbour wall so it can be removed.”
