A constant shift of society's dependence from petroleum-based energy resources towards renewable biomass-based has been the key to tackle the greenhouse gas emissions. Effective use of biomass feedstock, particularly lignocellulosic, has gained worldwide attention lately. Lignocellulosic biomass as a potent bioresource, however, cannot be a sustainable alternative if the production cost is too high and/ or the availability is limited. Recycling the lignocellulosic biomass from various sources into value added products such as bio-oil, biochar or other biobased chemicals in a bio-refinery model is a sensible idea. Combination of integrated conversion techniques along with process integration is suggested as a sustainable approach. Introducing 'series concept' accompanying intermittent dark/photo fermentation with co-cultivation of microalgae is conceptualised. While the cost of downstream processing for a single type of feedstock would be high, combining different feedstocks and integrating them in a bio-refinery model would lessen the production cost and reduce CO emission.
社会对石油基能源的依赖向可再生生物质的持续转变是解决温室气体排放的关键。最近，有效利用生物质原料，特别是木质纤维素，引起了全世界的关注。然而，如果生产成本过高和/或可用性有限，木质纤维素生物质作为一种有潜力的生物资源，就不能成为可持续的替代品。在生物炼制模型中将来自各种来源的木质纤维素生物质回收成增值产品，如生物油、生物炭或其他生物基化学品，是一个明智的想法。建议结合综合转化技术和过程集成，作为一种可持续的方法。引入“串联概念”，伴随间歇性暗/光发酵和微藻共培养。虽然单一类型原料的下游加工成本会很高，但将不同的原料结合起来并将它们整合到生物炼制模型中，将降低生产成本并减少 CO 排放。
