Life Cycle Assessment of an integrated rice steaming and drying unit fueled with rice husk

Authors: Kwofie, E., M. Ngadi, R. Kok
Description: Parboiling is a hydrothermal process for improving physical and nutritional quality of rice. This process of soaking, steaming and drying is energy intensive and requires up to 2750 MJ/tonne of paddy processed. To improve energy use and efficiency, a rice husk fueled integrated parboiling unit for simultaneous steaming and drying with the same fuel has been developed. In this study, a life cycle assessment with the view of analyzing both energy and environmental aspects of the unit is presented. This is based on the account of energy and material consumption, waste releases and atmospheric emissions during all relevant processes. Emission factors and global warming indicators are used for emission evaluation and compared with current fuel-wood use being practiced.
