Theoretical Bioenergy Potential in Cambodia and Laos

Abstract

This paper investigates theoretically potential energy of residues of some biomass sources in Cambodia and Laos by considering agricultural residues and forestry residues for the year 2006 since both country have limited access to grid-quality electricity. The theoretical potential biomass energy of rice husk, straw, corn cob, cassava stalk, bagasse and sugarcane trash and logging residues, sawnwood and plywood residues are calculated by using their lower heating values (LHV). The potential biomass energy obtained from these residues in Cambodia can contribute approximately 1.4 Mtoe to the total final energy consumption of Cambodia. On the other hand, 0.6 Mtoe biomass energy can be obtained potentially from the biomass residues in Laos, 2006. Furthermore, the paper presents the theoretical bioethanol production from some biomass residues such as rice straw, corn stover, bagasse, and cassava pulp in Cambodia and Laos. The potential bioethanol production in Cambodia is about 0,648 Gl for the year 2006 whereas 0,355 Gl of bioethanol can be produced in Laos from 2006 biomass residues. The potential results are investigated in whole country level and they do not consider the collecting and transportation cost of the biomass residues, their possible other usage purposes, exports and imports.
