Biomanufacturing has the potential to reduce demand for petrochemicals and mitigate climate change. Recent studies have also suggested that some of these products can be net carbon negative, effectively removing CO from the atmosphere and locking it up in products. This review explores the magnitude of carbon removal achievable through biomanufacturing and discusses the likely fate of carbon in a range of target molecules. Solvents, cleaning agents, or food and pharmaceutical additives will likely re-release their carbon as CO at the end of their functional lives, while carbon incorporated into non-compostable polymers can result in long-term sequestration. Future research can maximize its impact by focusing on reducing emissions, achieving performance advantages, and enabling a more circular carbon economy.
生物制造有潜力减少对石化产品的需求并缓解气候变化。最近的研究还表明，其中一些产品可以实现净碳负排放，有效地从大气中去除 CO 并将其锁定在产品中。本综述探讨了通过生物制造实现碳去除的幅度，并讨论了一系列目标分子中碳的可能归宿。溶剂、清洁剂或食品和医药添加剂在其功能寿命结束时可能会将其碳重新释放为 CO，而掺入不可堆肥聚合物中的碳则可能导致长期封存。未来的研究可以通过专注于减少排放、实现性能优势和实现更循环的碳经济来最大限度地发挥其影响。
