Banana fruit stalks promising material to make composite insulation boards

A researcher from the Department of Science and Technology-Forest Products Research and Development Institute (DOST-FPRDI) recently spoke about the waste material that is banana fruit stalks, also called peduncles.

“Our study shows that fibers from the fruit stalk of the saba banana [Musa paradisiaca] are promising material for composite insulation boards,” said engr. Gilberto N. Sapin of DOST-FPRDI. “Such boards can be used in tropical countries to keep heat outside of homes and buildings. The sample panels we produced are not yet perfect. We still need to make a few adjustments on them, but our initial findings are very encouraging.”

The Philippines is one of the world’s top producers of banana, therefore, one of the top generators of banana fruit stalk wastes. In Mindanao alone, some 1.35 billion kilograms of the stalks are produced every year and left in the fields to rot.

Sapin reported: “Mixed with the right amount of fibers and binders, the banana peduncle fibers we studied gave us boards suitable for thermal insulation. For tropical countries like the Philippines which are getting hotter temperatures due to the climate crisis, insulation panels will be very useful as they keep heat outside of homes and buildings.”
