One solution to the supply chain challenges of cellulosic biofuels is a network of local biomass processing depots (LBPDs) that can produce stable, dense, intermediate commodities and valuable co-products prior to shipping to a refinery. A techno-economic model of an LBPD facility that could incorporate multiple technologies and products was developed in Microsoft Excel to be used to economically and environmentally evaluate potential LBPD systems. In this study, three technologies (ammonia fiber expansion or AFEX (TM) pretreatment, fast pyrolysis, and leaf protein processing) were assessed for profitability. Pyrolysis was slightly profitable under the base conditions, leaf protein processing was highly unprofitable, and AFEX was profitable if biomass drying was not required. This model can be adapted to multiple feed-stocks and end uses, including both economic and environmental modeling. (C) 2011 Elsevier Ltd. All rights reserved.
