Disposable and Single-Use Product Design Pebble Bagasse Plate and Bowl by Simi Gauba from Duni AB The Pebble Collection is inspired by the organic shape of the humble pebble. These elegant plates and bowls are made from bagasse. Bagasse is a robust natural by-product of sugarcane, which is renewable and compostable. It requires fewer chemicals for processing and uses less energy to process. Once composted, it returns to soil in just 8 weeks. What better raw material to use for a single use/disposable plate and bowl.
