循环经济的概念旨在促进废物，残渣或副产品在可销售的化学品和中间体中的创新利用，同时提高过程经济性和环境可持续性。在生物精炼厂中，现在的重点已转向“腐殖质”，聚合缩合副产物的研究远远少于木质素。在许多基于生物的价值链中产生了腐殖质，这些链从多糖预处理开始，目标是获取C6和C5糖，然后进一步转化为基于呋喃或乙酰丙的平台化学品。它们是复杂且用途广泛的基材，并且由于其有机性质而可燃。因此，在本文中提出了关于腐殖质安全性问题的第一个见解，考虑到人们对腐殖质作为各种应用的新型生物基原料的兴趣日益浓厚。当前的研究提供了在全球范围内建立安全信息所必需的表征细节。首次尝试已获得了初步的安全数据，主要针对胡敏石的热量和火灾隐患，以确保安全存储，搬运，运输和加工。所得结果表明，迄今为止，腐殖质的总体着火危险与常规纤维素燃料（如木质材料）相似。安全信息的进一步整合应采用基于情景的风险评估方法，以限制在其他创新应用中安全使用腐殖质。运输和加工。所得结果表明，迄今为止，腐殖质的总体着火危险与常规纤维素燃料（如木质材料）相似。安全信息的进一步整合应采用基于情景的风险评估方法，以限制在其他创新应用中安全使用腐殖质。运输和加工。所得结果表明，迄今为止，腐殖质的总体着火危险与常规纤维素燃料（如木质材料）相似。安全信息的进一步整合应采用基于情景的风险评估方法，以限制在其他创新应用中安全使用腐殖质。

Insights on Thermal and Fire Hazards of Humins in Support of Their Sustainable Use in Advanced Biorefineries

The concept of circular economy is aiming at promoting innovative use of wastes, residues, or byproducts into marketable chemicals and intermediates, while enhancing process economics and environmental sustainability. Within biorefineries, the focus has now shifted toward “humins”, polymeric condensation byproducts far less investigated than lignins. Humins are produced in many biobased value chains that start from polysaccharides pretreatment, targeting access to C6 and C5 sugars and further conversion to furanics- or levulinics-based platform chemicals. They are complex and versatile substrates, and combustible because of their organic nature. A first insight on safety issues of humins is therefore proposed in this paper, considering the growing interest in humins as new biobased feedstocks for various applications. The current study provides characterization details necessary to establish safety information on a global context. This first attempt has brought in preliminary safety data mainly focusing on thermal and fire hazards of humins, to ensure safe storage, handling, transportation, and processing. The obtained results show that overall fire risk of humins so far is similar to that of the conventional cellulosic fuels such as woody materials. Further consolidation of safety information shall be done with a scenario-based risk assessment approach for conditioning safe use of humins in further innovative applications.
