Abstract: The perennial grass species Agropyron elongatum, commonly named "tall wheatgrass" (Poacea), has been gaining attention in recent years for its potential as a bioenergy and biorefinery feedstock. A. elongatum is native to southern Europe and Asia Minor, and was introduced to other places in the world as an energy crop, fodder and reclamation grass also marginal sandy soils. Therefore, A. elongatum is an attractive alternative to traditional energy crops such as corn and sugarcane. Improved biomass yield by targeted fertilization in sand using alternative nutrient carriers such as digestate has already been successfully demonstrated earlier and was transferred to the present investigation. One of the key benefits of using A. elongatum for energy and biorefinery applications is its high cellulose content and processability. Depending on the pre-treatment (alkaline or acidic) of the bulk, more than 75% crystalline cellulose and more than 25% lignin can be obtained. As demonstrated earlier, acid pre-treatment even allowed for a direct conversion of 25% of the cellulose into glucose without the need for enzymatic digestion.
