Every year the world produces at least 30 million tons of coconut, which are abundant in coastal areas of tropical countries. The coconut husk is composed of 30% fiber and 70% pith, with high lignin and phenolic content (Panyakaew and Fotios, 2011). Due to the high lignin content, coconut fiber is very elastic, durable, and resistant to rotting.

Glass can form naturally from volcanic magma. Obsidian is a common volcanic glass with high silica (SiO 2) content formed when felsic lava extruded from a volcano cools rapidly. Impactite is a form of glass formed by the impact of a meteorite, where Moldavite (found in central and eastern Europe), and Libyan desert glass (found in areas in the eastern Sahara, the deserts …
