将木质纤维素转化为增值产品通常集中在通过乙醇或热量生产燃料。在这项工作中，一个生物炼制三个产品流，纤维素，半纤维素和木质素的技术经济评估。此外，通过优化，在供应链的背景下对技术经济评估进行评估。一个混合整数线性规划，以允许灵活的方案，以确定供应链上的技术和预处理的变化的影响。技术经济和优化模型的整合是在苏格兰的案例研究中使用木质生物质，无论是作为锯材或锯木厂芯片。已确定锯木厂木片是首选，但一旦考虑被动干燥至30%含水量（湿基），锯木原木就具有竞争力。建模方法的灵活性允许在供应链的背景下考虑技术节约，这可能影响发展选择。
Conversion of lignocellulose to value-added products is normally focussed on fuel production via ethanol or heat. In this work, a techno-economic assessment of a biorefinery with three product streams, cellulose, hemicellulose and lignin is presented. Moreover, the techno-economic assessment is evaluated in the context of the supply chain through optimisation. A mixed integer linear program was developed to allow for flexible scenarios in order to determine effects of technological and pre-processing variations on the supply chain. The techno-economic and optimisation model integration was demonstrated on a case study in Scotland using woody biomass, either as sawnlogs or sawmill chips. It was established that sawmill chips is the preferred option, however sawnlogs became competitive once passive drying to 30% moisture content (wet basis) was considered. The flexibility of the modelling approach allowed for consideration of technology savings in the context of the supply chain, which can impact development choices.
