管理数量惊人的食物垃圾（约13亿吨）是一项严峻的挑战。可利用的未开发的食物垃圾可以成为建立生物精炼厂的有希望的原料，面包垃圾就是一个很好的例子。目前的审查重点是生物原料作为可持续生产平台和商业重要化学品的原料的能力。它描述了生物原料（100亿吨）作为可持续生物炼制原料的可用性，然后介绍了利用生物原料生产的平台化学品的例子，包括乙醇、乳酸、琥珀酸和2,3-丁二醇。这些代谢物的基于体重的生产与1G和2G（木质纤维素生物质）原料进行了比较。该评论还讨论了与使用生物质作为原料相关的物流和供应链挑战。最后，讨论了生物质生产的生命周期分析，并与其他原料进行了比较。
The management of staggering volume of food waste generated (∼1.3 billion tons) is a serious challenge. The readily available untapped food waste can be promising feedstock for setting up biorefineries and one good example is bread waste (BW). The current review emphasis on capability of BW as feedstock for sustainable production of platform and commercially important chemicals. It describes the availability of BW (>100 million tons) to serve as a feedstock for sustainable biorefineries followed by examples of platform chemicals which have been produced using BW including ethanol, lactic acid, succinic acid and 2,3-butanediol through biological route. The BW-based production of these metabolites is compared against 1G and 2G (lignocellulosic biomass) feedstocks. The review also discusses logistic and supply chain challenges associated with use of BW as feedstock. Towards the end, it is concluded with a discussion on life cycle analysis of BW-based production and comparison with other feedstocks.
