This Perspective explores how new technologies can expand lignocellulose biorefineries to include coproducts for animal feed and microbial protein with potential applications in human food. Using the Brazilian sugarcane industry as a case study, the analysis highlights synergies from the spatial coexistence of sugarcane and livestock, as well as economies of scale and product multiplicity in biorefineries. The technology outlook examines selected biomass pretreatments that can generate pretreated biomass with dual use: reactive intermediate for cellulosic ethanol production and ruminant nutrition. However, reliance on biorefined feed requires rebalancing ruminant diets and enhancing nutritional value. Emerging technologies for microbial protein production from biorefining streams are briefly contextualized, considering the potential addition in the diets of livestock and humans. In conclusion, research and development in this domain can unlock key opportunities to enhance the sustainability of bio-based value chains.
本视角探讨了新技术如何扩展木质纤维素生物精炼厂，使其包括用于动物饲料的副产品和微生物蛋白，并在人类食品中具有潜在应用。以巴西甘蔗产业为例进行分析，强调了甘蔗与牲畜在空间上共存所产生的协同效应，以及生物精炼厂的规模经济和产品多样性。技术展望研究了选定的生物质预处理方法，这些方法可以产生具有双重用途的预处理生物质：用于纤维素乙醇生产的反应中间体和反刍动物营养。然而，对生物精炼饲料的依赖需要重新平衡反刍动物饮食并提高营养价值。考虑到在牲畜和人类饮食中潜在的添加量，简要介绍了从生物精炼流中生产微生物蛋白的新兴技术。总之，该领域的研发可以开启增强生物基价值链可持续性的关键机遇。
