这一重要的审查提供了一个调查说明了最近的参考不同的战略，以实现可持续的生物质转化为生物产品。由于可能生产的化学产品数量巨大，因此已经完成了对起始材料和目标化学品的选择。此外，生物质热解或气化等热化学转化过程以及生物燃料的合成也没有考虑在内。通过转化由生物聚合物的解聚和发酵获得的平台分子来合成化学品是目前最广泛设想的方法。将研究这些结构单元成功地催化转化为中间体、特种产品和精细化学品。然而，平台分子价值链正在与来自化石资源的优化的、具有成本效益的合成路线竞争，以生产已经有市场的化学品。将分析涵盖生物聚合物在一个或几个步骤中转化为功能材料的替代价值链的文献。这种方法不需要使用分离的纯化学品，非常适合生产高吨位产品，如纸张添加剂，油漆，树脂，泡沫，表面活性剂，润滑剂和增塑剂。审查的另一个目标是严格审查转化过程的绿色特征，因为使用可再生能源作为原材料并不能免除遵守绿色化学原则（368篇参考文献）。
This critical review provides a survey illustrated by recent references of different strategies to achieve a sustainable conversion of biomass to bioproducts. Because of the huge number of chemical products that can be potentially manufactured, a selection of starting materials and targeted chemicals has been done. Also, thermochemical conversion processes such as biomass pyrolysis or gasification as well as the synthesis of biofuels were not considered. The synthesis of chemicals by conversion of platform molecules obtained by depolymerisation and fermentation of biopolymers is presently the most widely envisioned approach. Successful catalytic conversion of these building blocks into intermediates, specialties and fine chemicals will be examined. However, the platform molecule value chain is in competition with well-optimised, cost-effective synthesis routes from fossil resources to produce chemicals that have already a market. The literature covering alternative value chains whereby biopolymers are converted in one or few steps to functional materials will be analysed. This approach which does not require the use of isolated, pure chemicals is well adapted to produce high tonnage products, such as paper additives, paints, resins, foams, surfactants, lubricants, and plasticisers. Another objective of the review was to examine critically the green character of conversion processes because using renewables as raw materials does not exempt from abiding by green chemistry principles (368 references).
