Large-scale biofuel production requires a large geographical area of land to supply the necessary biomass (switchgrass, rapeseed, corn, wood, etc.). However, the larger a production facility gets, the farther biomass has to be transported, leading to increased fuel consumption, environmental impact, and cost of transport. Borrowing from the philosophy of the "buy local food" movement, this waste can be reduced by replacing large facilities with multiple, smaller production facilities distributed over the supporting land area. However, the economies-of-scale of the production facilities themselves do not favor this at present. Therefore, this proposal seeks to develop a new type of production strategy for biofuels, called semicontinuous processing. Semicontinuous processing is a novel processing intensification technique which uses a cyclic operating strategy to perform multiple separation or reaction steps in less equipment than typical continuous operating strategies. This has been shown in other contexts to significantly reduce the costs of operating at smaller scales.

大规模的生物燃料生产需要大面积的土地来提供必要的生物量（柳枝稷、油菜籽、玉米、木材等）。 然而，生产设施越大，生物质运输的距离就越远，导致燃料消耗、环境影响和运输成本增加。 借鉴“购买当地食品”运动的理念，可以通过将大型设施替换为分布在配套土地上的多个较小的生产设施来减少这种浪费。 然而，生产设施本身的规模经济目前并不支持这一点。 因此，该提案寻求开发一种新型的生物燃料生产战略，称为连续加工。 半连续过程是一种新型的过程强化技术，其使用循环操作策略在比典型的连续操作策略更少的设备中进行多个分离或反应步骤。 在其他情况下，这已表明可大大降低小规模运作的成本。
