Highly Durable Asphalt Modifier Made from Waste PET Developed at Kao Corporation

Kao Corporation ("Kao") developed NEWTLAC 5000, an asphalt modifier made from discarded PET materials (waste PET) through proprietary processing. While conventional asphalt modifiers improve the durability of asphalt pavements, NEWTLAC 5000's durability is several times longer, which ensures it produces less microplastic. This unique technology supports Kao in achieving its sustainability goals through "positive recycling"—creating a new business through recycling.
