Creating a “green composite binder material from industrial waste stabilisation” offers a more environmentally friendly approach for the benefit of future generations. Unlike conventional binders, which often rely on non-renewable materials like petroleum-based plastics and have adverse environmental effects, green binders contribute to a greener environment. They also have the potential to stimulate market demand for sustainable and eco-friendly products, thereby driving innovation within the binder industry. Various green binders have been created, such as using green polyol-based polyurethane for grouting substances and integrating liquid natural rubber to augment the durability of thermoset polymers. Analysis has shown that green polyol-based polyurethane's mechanical, physical, thermal, and morphological characteristics make it appropriate for use as grouting materials. Using liquid natural rubber as a toughening agent, combined with the insertion of carbon black filler and kenaf fibre as reinforcements, has dramatically enhanced rubber-toughened polyester composites’ mechanical, thermal, and electrical characteristics. The findings emphasise the potential of green binders as alternatives to petroleum-based binders.
