A new floating river park just opened on the Maas River, and it’s composed entirely of recycled plastic found within Rotterdam, Netherland’s rivers.

The structure, known as Recycled Park, is made from trash gathered by volunteers over a year-and-a-half timeframe. In addition, the city partnered with the Recycled Island Foundation to set what it called “passive litter traps” in the river and port to capture plastic waste.

The waste was recycled into 28 floating blocks that are bolted together to create islands that can be used as seating for visitors or plant beds for growing greens.

One man’s trash is another’s floating river park. At least that’s the case in Rotterdam, where a new floating structure called the Recycled Park just opened on the Maas River.

The 1,500-square-foot park is made from trash gathered from the city’s rivers over a year and a half. Volunteers scoured the city’s river banks for trash and the city partnered with the Recycled Island Foundation to set passive litter traps in the river and port to capture plastic waste via the stream’s natural current.
