一个简单的生物燃料生产系统，可以首先检查其政策的合规性方面的温室气体减排目标相对于化石燃料的同行。借助边际减排与额外经济利润的图形分析，可以发展出更具集成性和优化性的多联产生物精炼系统。这种自下而上的方法有助于通过综合系统设计实现更大的温室气体减排，从而为支持实现气候变化缓解目标的政策制定更严格的基准。综合经济价值和环境影响分析是一种多层次的方法，可用于将生物精炼系统性能表示为生物精炼产品的不同经济和环境影响边际的总和。在本文中，该方法扩展到支持过程集成策略，使生物炼制产品在温室气体排放量节约方面实现政策合规。介绍了产品的经济和环境影响概况，以图形方式显示经济成本和价值以及环境影响节约的赤字和盈余。扩展方法的有效性已被证明使用麻风树为基础的生物精炼系统将麻风树种子转化为生物柴油，甘油和蛋糕，作为一个案例研究。生产的生物柴油可实现53%的减排，而甘油和蛋糕可通过替代类似功能的化石产品实现57%的减排。
A simple biofuel production system can be first examined for its policy compliance in terms of GHG emission reduction target relative to fossil-based counterparts. More integrated and optimised biorefinery systems with polygeneration can then be evolved with the aid of graphical analysis of marginal emission savings vs. additional economic margins. This bottom-up approach helps to achieve greater GHG emission cut by integrated systems design and thereby setting a more stringent benchmark to support policies towards achieving climate change mitigation goals. The combined Economic Value and Environmental Impact analysis is a multi-level methodology that can be used to represent biorefinery system performances as an aggregate of differential economic and environmental impact margins of biorefinery products. The methodology is extended in this paper to support process integration strategies that allow achieving policy compliance of biorefinery products in terms of GHG emission savings. An economic and environmental impact profile of the products is introduced for a graphical visualisation of economic costs and values as well as deficits and surpluses in environmental impact savings. The effectiveness of the extended methodology has been demonstrated using a Jatropha-based biorefinery system converting Jatropha seed into biodiesel, glycerol and cake, as a case study. The biodiesel produced can achieve 53% emission cut, while glycerol and cake can achieve an emission cut by 57% by displacing similar functionality fossil based products.
