When I was in college, I got a job as a student researcher in my Engineering department. My job was to research coconuts. My professor was trying to find ways to turn coconuts into value-added products. The goal was help promote economic development in countries like Papua New Guinea where coconuts are plentiful but are not fully utilized. We researched all aspects of coconuts and how they can be used. As a result, I gained a lot of random knowledge about coconuts. So I thought that I would share some of the more interesting things with you. Here are some unusual uses or coconuts.
The husk of a fresh coconut is made of very strong fibers. The material between the fibers has a high lignin content. This lignin can act as a natural glue. All you have to do is shred the coconut husk and press it into a mold. Then heat it up to a few hundred degrees and it will turn into a solid board that is similar to medium density fiber board. You don't need to add any additional glue or filler. It can be made from 100% coconut husk. This can be used for construction just like regular fiber boards. Coconut boards are even being considered for use in car floor boards.
