Sungai Watch leads the first part of the process by identifying problem rivers and installing wide barriers to trap pollution. Since launching in 2020, the nonprofit has pulled 1,718,562 kilograms, nearly 1,900 tons, of plastic from the waterways.

Once cleaned and sorted, the waste is handed off to Sungai Design, which shreds and presses the material into large panels. CNC machines cut parametric components that are fashioned into a line of modern chairs, while offcuts are recycled into other products. Available in two shapes and three colors, the speckled designs both feature wide, sloping seats and angular legs. Each recycles an estimated 30 kilograms of plastic.
