Sustainable Products, Projects and Green Design Bonyeon Biodegradable Material by Jooen Lee Bonyeon is a biodegradable material used for household products such as lighting and trays. Bonyeon consists only of discarded agricultural and fishery byproducts, such as rice bran, bark and seaweed, bound with natural adhesives of proteins and microorganisms. The material is light and durable, and imitates the colour, scent and texture of nature. Bonyeon decomposes completely in a natural environment and leaves no harmful substances. Production is possible in a small workshop or at home with little capital, and the use of byproducts adds income for farming and fishing villages.
