Utilization of Banana Peel and Carton Waste in Manufacturing of Thermal Insulation Board

As the temperature continues to rise due to global warming, the used of polyurethane thermal insulation foam board has become prevalent over the recent years. Despite its usefulness, it has a negative impact on our environment because the production of a pound of polyurethane foam board emits 3.7 pounds of carbon dioxide. Several studies have found that banana peel and carton waste can be used as a potential substitute in the production of polyurethane thermal insulation foam board due to its thermal resistivity. This study employed four different tests which includes flammability test, bend test, screw test and thermal capability test to determine the effectiveness of the product. The tests result showed that the best proportion to produce an affordable, lightweight and environment friendly insulation board is 31.33% banana peel, 31.33% carton waste, 23.50% banana resin, 7.8% polyvinyl acetate and 6% chlorinated rubber paint. The computed payback period is 4 years and 266 days, indicating that the business is feasible.
