When used as a fuel, cellulosic ethanol releases less sulfur, carbon monoxide, particulates, and greenhouse gases.
en.wikipedia.org Many types of cellulosic materials have been used, including newspaper, cardboard, cotton, straw, sawdust, hemp and corncob.
en.wikipedia.org Corn ethanol may reduce overall GHG emissions by about 13%, while that figure is around 88% or greater for cellulosic ethanol.
en.wikipedia.org With advanced technology being developed, cellulosic biomass, such as trees and grasses, are also used as feedstocks for ethanol production.
en.wikipedia.org The properties of plastic-based synthetic fibers, most important among them being polyamide, polyester and polyacrylonitrile, are essentially different from those of natural cellulosic and wool fibers.
