Benefit of using rice husk as a biomass fuel is from the ash after the rice husk has been combusted. The Rice Husk Ash (abbreviated to RHA), is particularly high in silica (Si). Silica is an important raw material for many purposes, and RHA is therefore becoming increasingly valuable.
Dec 1, 2023 · Compared to traditional fillers like carbon black and synthetic silica, rice husk-derived silica offers a cost-effective alternative without compromising performance [156]. From an environmental perspective, rice husk-derived silica aligns with sustainability efforts by utilizing an abundant agricultural waste product.
