Water-Related to Bioethanal Production in Thailand
คำสำคัญ:
Bio-ethanol, life-cycle consumptive water use, water resource managementบทคัดย่อ
The Thai government has been promoting a bio-ethanol production to reduce
greenhouse gas emissions and government expenses on crude oil imports. There
are many profound concerns related to such policy especially limited fresh water
resources of crops. This study provides an overview of bio-ethanol water footprint
in sugarcane and cassava based ethanol which is the main sources of bio-fuel
production in Thailand. The result shows that the production of bio-ethanol requires
large amount of consumptive water use. The government should aware of this
tremendous increasing demand in the areas where farms and ethanol plants are
located to avoid water shortages and conflicted uses between industrial sector and
human consumption. Additionally, irrigation systems and water allocation policy
should be adjusted properly for this oil transition.
