用于生产电力、运输燃料和各种化学品的农作物生物精炼有可能为生物质提供显着的经济附加值。工业资源基础从化石资源向生物质资源的转变也需要原材料生产、处理和加工的技术基础的转变。生物技术将在为生物质生产、处理、增值到各种产品等不同阶段提供工具方面发挥重要作用。第一代炼油厂提出了一些与土地利用和能源密集型作物种植造成的环境效益不足相关的关键问题。丰富的残余木质纤维素生物质将构成未来生物精炼厂的重要原料，从而将对粮食供应的影响降至最低。从长远来看，需要对技术开发进行必要的投资，以实现新生物经济的好处。
Biorefining of crops for production of power, transport fuels, and a diverse array of chemicals has potential for providing significant added economic value to biomass. A shift in the industrial resource base from fossil resources to biomass also requires a shift in the technology base for producing, handling, and processing of raw materials. Biotechnology will play an important role in providing tools for different stages ranging from biomass production, treatment, and valorization to various products. First generation refineries have raised some critical issues related to land use and insufficient environmental benefits due to energy-intensive cultivation of crops. The abundant residual lignocellulosic biomass will constitute an important feedstock for the future biorefineries so as to have a minimal impact on the food availability. Necessary investments in technological development will be needed to realize the benefits of the new bio-economy in the long term.
