A novel method to recover VFAs from a continually-fed 100 L food waste bioreactor was developed using industrially applicable methods. The in-situ recovery of VFAs increased production rates from 4 to 35 mg_vfa g_vs⁻¹ day⁻¹ by alleviating end-product inhibition and arresting methanogenesis, and electrodialysis was able to concentrate the recovered VFAs to 4000 mg L⁻¹. There remains considerable scope to increase the production rates and concentrations further, and the VFAs were recovered in a form that made them suitable for use as platform chemicals with minimal refining. This is the first time that continuous VFA recovery from real-world food waste has been reported at this scale with continual feeding, and represents a promising means through which to produce sustainable platform chemicals. Furthermore the production of VFAs arrests methane production in bioreactors, which is a low value product around which there is a growing concern about fugitive emissions contributing to climate change.

利用工业上可应用的方法，开发了一种从连续进料的100 L食物垃圾生物反应器中回收VFA的新方法。在原位的VFA的回收率提高的生产速率从4至35mg _VFA克_VS ^-1天^-1通过减轻终产物抑制和阻止甲烷，和电渗析能够以浓缩回收的VFA至4000毫克的L ^-1。仍有很大的空间可以进一步提高生产率和浓度，并且以某种形式回收了VFA，使其非常适合用作平台化学品，而无需进行精制。这是首次报道了通过连续进料以这种规模连续不断地从现实世界的食物垃圾中回收VFA，这是生产可持续的平台化学品的有希望的手段。此外，VFA的生产阻止了生物反应器中的甲烷生产，这是一种低价值产品，人们越来越关注逸散性排放对气候变化的影响。
