Abstract

5-Hydroxymethyl furfurals (HMF) is one of the versatile platform chemicals. However, green routes to produce it directly from lignocellulosic biomass are lacking. A significant amount of HMF produced during the hydrothermal valorization of lignocellulosic biomass is considered undesired and ends up in a waste stream. The study transformed the undesired byproduct into a valuable coproduct by advancing the existing biofuel production process. A detailed economic and environmental sustainability analysis of the integrated biorefinery design was performed. The evaluation showed that the biorefinery could afford a maximum feedstock purchasing price of $115.17 per MT and produce HMF with a minimum selling price of $4.54 per kg which is ∼75% lower than the commercial price of HMF. The median global warming potential of HMF was estimated to be 3.92 kg CO₂-eq. per kg HMF which was ∼32% less than its counterpart bio-based p-xylene. Diverse coproducts produced in the biorefinery using transgenic feedstock positively impacted sustainability.

从木质纤维素生物质中生产和回收生物基 HMF 的经济和环境可持续性†。

5- 羟甲基呋喃（HMF）是一种多功能平台化学品。然而，目前还缺乏直接从木质纤维素生物质中生产这种物质的绿色途径。在木质纤维素生物质水热值化过程中产生的大量 HMF 被认为是不需要的，最终成为废物流。该研究通过推进现有的生物燃料生产工艺，将不受欢迎的副产品转化为有价值的副产品。对综合生物精炼厂设计进行了详细的经济和环境可持续性分析。评估结果表明，该生物精炼厂可承受的最高原料采购价格为每公吨 115.17 美元，生产的 HMF 最低销售价格为每公斤 4.54 美元，比 HMF 的商业价格低 75%。据估计，HMF 的全球变暖潜势中值为每公斤 HMF 3.92 公斤二氧化碳当量，比其对应的生物基对二甲苯低 32%。生物精炼厂利用转基因原料生产的多种副产品对可持续发展产生了积极影响。

期刊介绍： Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
