Biorefinery based on multi-feedstock lignocellulose can be viable where a sustainable supply of a single substrate is limited, for example in arid regions. Processing of mixed feedstocks has been studied in lab scale, however, its economics are less studied. In this study, an economic comparison was made between separate and combined (mixed) processing approaches for multi-feedstock lignocellulose for the production of monomeric sugars. This modular approach of focusing on sugar platform makes the results applicable for many applications using the sugars as feedstock. Feedstock considered in this study were the green and woody lignocellulose residues: Bermuda grass, Jasmine hedges, and date palm fronds. Results showed that, at an identical total feed rate, combined processing was more advantageous as compared to separate processing. A further sensitivity analysis on mixed combined processing showed that the cellulase enzyme price and feed price are the two major factors affecting the production cost.
基于多原料木质纤维素的生物炼制在单一底物可持续供应有限的情况下是可行的，例如在干旱地区。已经在实验室规模上研究了混合原料的处理，但对其经济性的研究较少。在这项研究中，对生产单糖的多原料木质纤维素的单独和组合（混合）处理方法进行了经济比较。这种关注糖平台的模块化方法使结果可适用于许多使用糖作为原料的应用。本研究中考虑的原料是绿色和木质纤维素废料：百慕大草、茉莉树篱和枣椰树的叶子。结果表明，在相同的总进料速率下，与单独处理相比，组合处理更有利。对混合组合处理的进一步敏感性分析表明，纤维素酶价格和饲料价格是影响生产成本的两个主要因素。
