• The goal is to propose a • management model for the transport of agro-

industrial waste from the harvesting of sugar cane from the field to the collection site.

- Know the operations management or logistics of harvesting sugar cane in sugar mills general

- Describe the characteristics, uses and management that are giving crop residues of sugar cane in various countries and in Colombia, especially in the Ingenio Manuelita.

- Identify technologies that are being used or have been used at national or international transport of agro-industrial waste from the field.

• Develop a model to make a decision to minimize travel to major estates and maximizing resources and equipment to use.

• Evaluated using the simulation model to optimize the transport of waste.

• And finally, design a support system for making decisions in the process of transporting the waste from sugar cane.

• Standardization of methods for green harvesting residues characterization

• Determining composition variability according to lignocellulosic feedstock type and origin in order to determine its effect in subsequent stages of bioethanol production.

• Organosolv delignification of sugarcane green harvesting residues

• Ultrasound delignification of sugarcane green harvesting residues
