ECOBI (Eco friendly biofoam) is a biofoam product that can be used as a substitute for styrofoam. This product is made from waste of cassava dregs ( Manihot utilissima ) which contains starch and corn ( Zea mays) which contains fiber. So, this product is not only biodegradable but also renewable. In the process of making ECOBI, it does not use harmful chemicals such as carcinogenic benzene and styrene, but takes advantage of the ability of starch to expand due to heat and pressure processes.
