The pressing impact of climate change is forcing our species to rethink the way we live our day-to-day lives. The rising CO2 levels in the atmosphere have been strongly correlated to the emissions generated from energy production, and as society seeks alternate energy sources, the influence that petrochemicals once held would seem to be in decline. However, carbon is still essential to feed the chemicals market. It forms the backbone of almost all molecular structures used in commercial goods, so it is clear it still needs to be provided from somewhere. Although the petrochemical industry fights to continue sourcing the market by reconfiguring its processing techniques, its non-renewable nature and poor recyclability necessitates a replacement for a sustainable future. Biomass, organically derived carbonaceous matter, is believed to be the most promising alternative for a fully integrated circular economy.Its highly diverse geographical distribution combined with its abundance and ability to produce a diverse plethora of platform molecules are just some of the reasons behind the widespread interest. Nonetheless, several challenges still exist in generating products from these feedstocks. The highly topical discussion regarding land use for food vs fuels is currently prohibiting the mass adoption of biochemicals sourced from microbially catalysed processes. In response, there has been much research covering the application of 2nd generation feedstocks. Predominantly composed of lignocellulosic substrates, these feedstocks offer an alternate route to the production of glucose streams that can be sourced from by-products of the agricultural industry. However, given the more recalcitrant nature of this feedstock, harsher pre-processing conditions are required. This typically results in conditions unsuitable for biological processes due to the spectra of inhibitorysubstances that remain in the feed. Resultingly, greater attention has been given to the importance of chemocatalytic upgrading routes for these process streams.

气候变化的紧迫影响正迫使人类重新思考我们的日常生活方式。大气中不断上升的二氧化碳水平与能源生产产生的排放密切相关，随着社会寻求替代能源，石油化工曾经拥有的影响力似乎正在下降。然而，碳仍然是供应化学品市场的必需品。它构成了几乎所有用于商业商品的分子结构的支柱，所以很明显，它仍然需要从某个地方提供。尽管石化行业通过重新配置其加工技术来争取继续采购市场，但其不可再生的性质和较差的可回收性需要替代可持续的未来。生物质，有机衍生的碳质物质，被认为是完全一体化循环经济最有希望的替代方案。它高度多样化的地理分布，加上它的丰富和生产各种平台分子的能力，只是广泛兴趣背后的一些原因。尽管如此，从这些原料生产产品仍然存在一些挑战。关于粮食与燃料的土地利用的高度热门讨论目前禁止大规模采用来自微生物催化过程的生化物质。因此，关于第二代原料的应用研究也越来越多。这些原料主要由木质纤维素底物组成，为生产可从农业副产品中获取的葡萄糖流提供了另一种途径。然而，考虑到这种原料的顽固性，需要更苛刻的预处理条件。由于饲料中残留的抑制物质的光谱，这通常会导致不适合生物过程的条件。因此，人们更加重视这些工艺流程的化学催化升级路线的重要性。
