The accumulation of agricultural waste either in solid or liquid form causes environmental concern. In the utilisation of agricultural waste for developing sustainable construction material, cyclotriphosphazene-incorporated sago wastes as pendant groups were prepared and structurally characterised using infrared spectroscope and scanning electron microscope. The chemically-modified sago waste composite was applied with binders and developed as sound-absorbing panels. These panels are a class of organic–inorganic-based material that is fire resistant. The absorption coefficient of panels gave higher values at low (250 and 500 Hz) and medium (2000 Hz) frequencies. The panel was 51% lighter than fibreboard. The function and basic manufacturing of sound-absorbing panels were similar to other products available in the market. The panels showed excellent anti-termite properties.
