India’s construction industry is increasingly looking beyond conventional materials as the demand for sustainable and durable alternatives grows. One Chennai-based innovation is showing how agricultural waste can become a valuable resource for the built environment.
Indowud has developed Natural Fibre Composite (NFC) boards using rice husk, an agricultural by-product that is often discarded or burned. By converting this waste into wood alternatives, the company aims to reduce dependence on conventional timber while creating a productive use for agricultural residue.
The process involves transforming rice husk into a composite material that can be used across interiors, furniture and exterior applications. According to Indowud, its boards are designed to offer resistance to water, termites, weather and fire, making them suitable for demanding Indian conditions. They can be used for applications including furniture, wardrobes, partitions, wall panels, cladding and other architectural elements.
The concept also addresses two environmental challenges simultaneously: agricultural waste management and pressure on forests. Earlier reporting on the company highlighted its goal of creating a zero-wood alternative to plywood, while sourcing rice husk from farmers and nearby rice mills around its Chennai facility.
