Abstract for: Model for Assessment Sustainability Indicators in biofuels.

A method for representing systems that allows the study of chance and necessity is required for a dynamics sustainability indicators assessment. Therefore, in this study a model for dynamic and prospective assessment of the sustainability in biofuels, was developed. The proposal of this work is shown with an example in the bioethanol production from sugarcane in Colombia. First, a model of a bioethanol supply chain is obtained and it is linked with associated variables which represent sustainability indicators, these indicators were proposed by the Global Bioenergy Partnership- GBEP. Then desired regions of the state of the system and indicators are suggested, which were defined for some Time of Evaluation of sustainability such as: Desired Scenario, Alert Scenario and Non Desired Scenario. This model allowed important findings for monitoring and evaluation of sustainability in biofuels production.
