A biorefinery scheme with separate processing of the two main carbohydrate streams (cellulose and hemicellulose-derived) was employed to the energy crop cardoon (Cynara cardunculus L). to fractionate the whole stalk material.
All the material was dried to constant weight in an oven at 60 °C and the dry mass of leaf and stalk material determined individually for each pot.
There are circumstances in which it would be convenient to harvest stalk material and then proceed with the isolation of cores at a later time.
The dried stalk material was subsequently ground and sieved (1 mm mesh) for determination of Si content in Trial 1, and Si and N [using Kjeldahl method for N; (Sahrawat et al. 2002)] content in Trial 2, separately for each pot.
As the IPL matures and RGCs extend processes further into the IPL, iAC and dAC somas appear to move further apart owing to the growing IPL, such that iACs and dACs with somas originally directly adjacent to the BC plexus develop a short stalk (supplementary material Fig. S6).
Alongside PLA fibres, firms are investigating plants such as bamboo, seaweed, nettles and banana stalks as raw materials for textiles.
He said only the stalk and waste material was used in second generation biofuels fermentation, allowing corn, soya or other foodstuff to be saved for making food.
Mr. Hershkowitz said that using agricultural waste products, like corn stalks or other materials left over from farming, was better than using crops, such as sugarcane or corn that are grown specifically for plastic production.
Plant stalks are cellulosic materials consisting of cellulose, hemicelluloses and lignin.
The aim of this work was to evaluate cotton stalk (waste plant material after harvesting the cotton) as feedstock for bioethanol production.
