Growing concerns around the generation of biomass waste have triggered conversation around sustainable utilization of these seemingly waste materials as feedstock towards energy generation and production of chemicals and other value-added products. Thus, biotechniques such as utilization of microbes and enzymes derived thereof have become important avenues for green pretreatment and conversion of biomass wastes. Although the products of these bioconversions are greener at an overall level, their consumption and utilization still impact the environment. Hence it is important to understand the overall impact from cradle to grave through lifecycle assessment (LCA) techniques and find avenues of process optimization and better utilization of all the materials and products involved. Another factor to consider is overall cost optimization to make the process economically feasible, profitable and increase industrial adoption. This review brings forward these critical aspects to provide better understanding for the advancement of bioeconomy.
人们对生物质废料产生的担忧日益加剧，这促使人们开始探讨如何以可持续的方式利用这些看似无用的材料作为原料，以用于能源生产、化学品和其他增值产品的制造。因此，利用微生物和其衍生酶等生物技术已成为绿色预处理和生物质废料转化的重要途径。尽管这些生物转化的产物在整体上更加环保，但它们的消耗和利用仍会对环境产生影响。因此，通过生命周期评估（LCA）技术了解从摇篮到坟墓的整体影响，并找到优化工艺和更好地利用所涉及的所有材料和产品的途径非常重要。另一个需要考虑的因素是优化总成本，使该工艺在经济上可行、盈利，并提高工业采用率。本综述提出了这些关键方面，以期为生物经济的发展提供更好的理解。
