In fact, Weidema et al. (2009) identified that the dependent products which are not fully utilised will require waste treatment process and the use of the non-fully utilised dependent products will avoid the waste treatment. In this study it is assumed in these sensitivity scenarios that the dependent products (molasses and bagasse) will be stored without throwing them as waste due to their economic values. Therefore, the avoided waste treatment is not included. Although the cases on which molasses and bagasse are not fully utilised may be possible, these unconstrained condi- tions have to be further assessed to ascertain whether they are realistic for the case of Thailand.
