Abstract:
Lignocellulosic biomass as can be derived from post-harvesting process in agricultural section in Thailand are abundant resources, which could potentially replace conventional feedstocks and benefit in saving plantation areas and avoiding food-energy competition. The current work aims to propose schematic designs of decentralized production in order to effectively exploit dispersedly available residual biomass. Determination of optimal locations for decentralized facilities is conducted through the suitability analysis, using integrated methods from multi-criteria decision analysis and geographical information systems (GIS-MCA). The present study explores the optimal numbers of installation units based on the best installation proposal for maximizing residues collection. Moreover, by increasing facility units in respective regions, agricultural residues could be spatially covered in broader areas, leading to more accessibility to higher utilization rates in total. The advantage of decentralized function has also been discovered regarding the logistics cost reduction due to shorter delivery distances per bioethanol capacity. Although implementing decentralized biorefineries involves small-scale productions that would result in higher total capital investment, the decentralized configuration is a promising system that allows the regionalized biomass to be systematically valoraized and developed into higher valued biobased products.
