Abstract: A method of manufacturing sugar cane polyvinyl alcohol wherein sugar cane bagasse is processed into polyvinyl alcohol. Processing raw materials including sugar cane bagasse and deionized water. Enzymatically hydrolyzing and using saccharification on the sugar cane bagasse to obtain sugar cane bagasse enzymatic hydrolysate. Fermenting the sugar cane bagasse solution. Distilling the fermented sugar cane bagasse solution to obtain ethanol solution and lignin solution. Transferring the distilled solutions to an ethylene plant area to obtain a polymer grade ethylene product. Transferring the polymer grade ethylene product to an acetic acid evaporator to generate vinyl acetate. Introducing the vinyl acetate into an autoclave with methanol solution wherein said solutions undergo a reflux reaction process. Ethyl acetate is then dissolved in methanol to prepare a polyvinyl acetate solution which undergoes alcoholysis wherein the product is then washed and deionized, yielding polyvinyl alcohol.
