Manufacture Of Value Added Products From Rice Husk Guide

Rice husk is increasingly used as a sustainable alternative to traditional wood and cement products due to its natural moisture and termite resistance.

Rice husk (RH), making up approximately 20% of paddy weight, is a resource-rich agricultural byproduct composed primarily of , lignin (20–25%) , and silica (15–20%) . Traditionally discarded or burned, it is now being manufactured into a diverse range of value-added products across multiple industries. 1.

RHA contains over , which can be chemically extracted for high-value applications. Rice husk is increasingly used as a sustainable

: Rice Husk Ash (RHA) acts as a highly reactive pozzolan, replacing 10–25% of Ordinary Portland Cement. This reduces the carbon footprint of construction while increasing the compressive strength and durability of the concrete. This reduces the carbon footprint of construction while

: Manufacturers like Modern Mill produce ACRE, a wood-free composite that resists rot and UV damage. These boards serve as termite-resistant alternatives to plywood and MDF for modular construction and furniture.

: Raw husks or compressed panels are used for translucent thermal insulation in walls and roofs, maintaining indoor temperatures effectively due to their low thermal conductivity. 2. Industrial Silica Extraction
