TL;DR: Transportation biofuels such as synfuel hydrocarbons or cellulosic ethanol, if produced from low-input biomass grown on agriculturally marginal land or from waste biomass, could provide much greater supplies and environmental benefits than food-basedBiofuels.

TL;DR: In this article, the authors present an optimization study of the net present value of a biomass-to-ethanol supply chain in a 9-state region in the Midwestern United States.

TL;DR: In this paper, the authors evaluated the economics, energy inputs, and greenhouse gas (GHG) emissions for a proposed "field to facility" corn stover logistics system, which included collection and transport by round bales to local storages within 3.2 km (2 mile) of the field during the fall harvest period followed by processing at the local storage sites throughout the year using mobile units which converted the bales into bulk material by tub-grinding and roll-press compacting to 240 kg/m 3 (15 lb/ft 3 ) to achieve 22.7

TL;DR: In this article, a spreadsheet model is used to conduct the analysis based on the assumptions and interactions of various factors, such as corn prices, ethanol prices, DDGS and CO2, natural gas prices, and interest rates.

TL;DR: In this article, the development of the production factors for wood pellet markets in Finland, Germany, Sweden, Norway and the US is analyzed. But the analysis is based on two model plants, one for small-scale pellet production based on dry residues from sawnwood production, and the other for large-scale production using a blend of dry and wet materials.
