Each kg of paddy grain produces around ∼ 0.20–0.25 kg of rice husk (RH) during the milling process. RH has poor nutritive value but retains significant calorific value (∼15 MJ/kg) [39]. Thus, it is usually utilized as a fuel in boilers via combustion. This burning process generates ∼25 wt% of waste, namely Rice husk ash (RHA).
