Life Cycle Assessment of second generation bioethanol produced from low-input dedicated crops of Arundo donax L.

abstract：:Cellulosic plant material represents an as-of-yet untapped source of fermentable sugars for significant industrial use. Many physio-chemical structural and compositional factors hinder the enzymatic digestibility of cellulose present in lignocellulosic biomass. The goal of any pretreatment technology is to alter or re...
