Rice straw and rice husks occur in large quantities as side streams of the world wide rice production. These side streams can be used as a renewable source of energy via the biochemical as well as the thermochemical conversion route. Exemplarily for samples from various South-East Asian countries, the most important characterizing figures are measured analytically. Then, the two conversion routes—based on a thermochemical as well as on a biochemical conversion—are discussed in detail. Based on such technological solutions as well as the measured data, nine case studies for each conversion system are defined and assessed related to the levelized costs of electricity (LCOEl) and energy (LCOEn). Additionally, the specific substrate demands (SSDs) and specific land demands (SLDs) are calculated indicating the mass and area efficiency of chosen substrates and systems.
