3. Introduction
The major residues from sugarcane harvesting & Processing are;
Sugarcane Leaves & Tops referred to as Sugarcane Trash
Sugarcane Bagasse
Sugarcane Molasses

4. Introduction contd. Hemi-cellulose Lignin
The Major constituents of Sugarcane Bagasse & Trash are;
Cellulose
Hemi-cellulose
Lignin

5. Introduction contd.
Sugarcane bagasse and Sugarcane Trash can be converted to bioethanol through several biochemical conversion processes
Bioethanol is a biofuel capable of serving as alternative energy source can be Produced

6. Schematic of Ethanol Production from Sugarcane Bagasse & Sugarcane Trash

7. A diagram showing sugarcane bagasse & Trash both obtained from sugarcane plants

8. Significance of Study
Nigeria has failed to harness sugarcane residues in bioethanol production despite the realization that bioethanol can serve as an alternative energy source to replace or complement the existing energy sources
Fortunately Sugarcane is grown as cash crop in several communities of Bayelsa State
This study focuses on the production of bioethanol from the sugarcane bagasse & trash readily available in Bayelsa communities in large quantities
The use of sugarcane bagasse to generate energy will further reduce problems associated with waste management such as pollution, greenhouse gaseous emissions and fossil fuels use

9. Problem statement
Rising cost of fossil fuel-based petroleum products has made the product unaffordable to rural dwellers that constitute about 70% of Nigeria’s population
Most parts of Nigeria are suitable for biofuels crops cultivation and so the country cannot afford to be left behind in the recent quest for renewable sources of energy
The use of Sugarcane bagasse & trash as feedstock for bioethanol production would not compete with staple food
The study of bioethanol production obtained sugarcane bagasse & trash would provide industrialists a feedstock base to set up a bioethanol production plant in Bayelsa state

10. Objectives
To conduct an extensive review previous works on the production of bioethanol from sugarcane bagasse and sugarcane trash
To compare the yield of bioethanol using sugarcane bagasse and a combination of sugarcane bagasse and trash
To investigate the effects of Temperature, Concentration and some other on the yield of Ethanol during fermentation

11. Scope of work
There have been numerous research projects that have extensively reviewed the production of bioethanol from agro wastes like sugarcane bagasse, rice husk, wheat straw, corn fiber, crop residues, grasses etc.
Therefore the scope of this research will be limited to a comparative analysis using of sugarcane bagasse and sugarcane trash as feedstock for the production of bioethanol

12. Limitations
Only sugarcane residues namely; bagasse, leaves and trash were experimented on as feedstock for bioethanol production. Other agro-based residues were exempted
The pretreatment and hydrolysis methods were restricted only to acid pretreatment and acid hydrolysis. The use of Enzymes for the pretreatment or hydrolysis is ignored

13. Methodology The basic stages of this process will be;
A "pre-treatment" phase, to make the samples amenable to hydrolysis
Hydrolysis, to break down the molecules of cellulose into sugars
Extraction of fermenting yeast from palm wine
Yeast fermentation of the sugar solution
Distillation to produce 99.5% pure ethanol

14. Expected outcome
The ethanol concentration should increase as the number of days increases
The ethanol concentration should decrease as the molarity of acid used is increased
The statistical analysis of variance will indicate that the process variables will have a significant effect on the yield of bioethanol from sugarcane bagasse and sugarcane trash
