Waste Management in Rice Mills: Turning By-products into Sustainable Resources

Rice milling generates significant waste including husk, bran, broken rice, and wastewater. Modern waste management is essential for sustainability, efficiency, and profitability.

Rice Mill Waste Types

• Rice husk: outer paddy layer removed during de-husking
• Rice bran: nutrient-rich layer removed during polishing
• Broken rice: grains damaged during milling
• Wastewater: from soaking and parboiling

Waste Management Strategies

Rice Husk: Convert to biomass fuel for boiler energy generation or process into ash for cement and silica industries.

Rice Bran: Extract oil for additional income; residue serves as animal feed or fertilizer.

Broken Rice: Sell in local markets or process into flour and other food products.
