Sungai Design’s source of materials comes from its sister organisation, Sungai Watch, a nonprofit working to intercept and recover waste from Indonesia’s most polluted rivers. Sungai Watch collects, sorts, and processes river waste for up-cycling, ensuring that discarded materials are transformed instead of ending up in the ocean. With an estimated 80% of ocean pollution originating from rivers, the team focuses on stopping waste at the source. To date, Sungai Watch has installed over 400 floating barriers across the country to intercept river waste and has collected more than 4,000,000 kg of waste.
