Aromatic chemicals are crucial in bioplastics to convey functionality, including strength and flexibility. Currently, these aromatic chemicals can only be sourced from fossil based inputs, limiting applications, increasing the cost and environmental impact. Lignin, the 2nd most abundant organic polymer in plants, is one of the few potential natural sources of aromatic chemicals. Building on a successful feasibility study that proved that the aromatic diacids inherent within lignin could be extracted and substituted in polyester based plastics, this project aims to demonstrate that these metabolites can be produced in a commercially viable manner by the innovative use of modified bacteria to selectively control lignin disintegration when matched with novel chemical processes in scalable batch/continuous reactors. Larger trials will convert the resultant kg quantities of diacids into novel block copolyesters, for evaluation in a high value global bioplastics market of value >£150m.

芳香族化学物质在生物塑料中是传递功能的关键，包括强度和灵活性。目前，这些芳香族化学品只能来自化石原料，限制了应用，增加了成本和对环境的影响。木质素是植物中含量第二丰富的有机聚合物，是芳香族化学物质的少数潜在天然来源之一。在一项成功的可行性研究的基础上，该项目证明了可以在聚酯塑料中提取和取代木质素中固有的芳香族二元酸，该项目旨在证明，当与可扩展的间歇/连续反应器中的新化学工艺相匹配时，通过创新地使用改良的细菌来选择性地控制木质素的分解，可以以商业可行的方式生产这些代谢物。更大规模的试验将把合成的千克二元酸转化为新型嵌段共聚酯，在价值1.5亿英镑的高价值全球生物塑料市场进行评估。
