  Around 70 million tons of oranges are grown worldwide per year.

During the production of orange juice, it is estimated that up to 20 million tons of waste is produced mainly from the peel, pulp, seeds, orange leaves and fruits that do not meet quality standards. Among them, only little percentage of orange waste is turned into pellets for animal feed, spread onto soil or simply burned. Many researches insist that food waste has hidden-effective values and oranges are the excellent example that could shows the possibility that utilizes food waste resources.

After extracting the juice, around half of the orange is discarded. Orange peels contain soluble sugars, cellulose, pectin and other essential oils that could form the basis for several industrial processes. The peel has largely divided into two sections, exocarp (orange colour) and mesocarp (white colour). Based on researches and experiments, I obtained two types and colours and comparable strength to wood.
