“…Machinery and equipment costs were estimated with the MachData model (Lazarus, ), which uses economic engineering‐based estimates of per‐hour and per‐acre costs of labor, tractor, and equipment use. This machinery cost estimator is used widely by farm management advisors and farm managers (Myhre, ; Venuto & Daniel, ; Maung & Gustafson, ). The results indicate a representative cost per activity rather than that specifically incurred in the field – or in this case, on the research plot.…”

Switchgrass (Panicum virgatum L.) has been the principal perennial herbaceous crop investigated for bioenergy production in North America given its high production potential, relatively low input requirements, and potential suitability for use on marginal lands. Few large trials have determined switchgrass yields at field scale on marginal lands, including analysis of production costs. Thus, a field-scale study was conducted to develop realistic yield and cost estimates for diverse regions of the USA. Objectives included measuring switchgrass response to fertility treatments (0, 56, and 112 kg N ha À1 ) and generating corresponding estimates of production costs for sites with diverse soil and climatic conditions. Trials occurred in Iowa, New York, Oklahoma, South Dakota, and Virginia, USA. Cultivars and management practices were site specific, and field-scale equipment was used for all management practices. Input costs were estimated using final harvest-year (2015) prices, and equipment operation costs were estimated with the MachData model ($2015). Switchgrass yields generally were below those reported elsewhere, averaging 6.3 Mg ha À1 across sites and treatments. Establishment stand percent ranged from 28% to 76% and was linked to initial year production. No response to N was observed at any site in the first production year. In subsequent seasons, N generally increased yields on well-drained soils; however, responses to N were nil or negative on less well-drained soils. Greatest percent increases in response to 112 kg N ha À1 were 57% and 76% on well-drained South Dakota and Virginia sites, where breakeven prices to justify N applications were over $70 and $63 Mg À1 , respectively. For some sites, typically promoted N application rates may be economically unjustified; it remains unknown whether a bioenergy industry can support the breakeven prices estimated for sites where N inputs had positive effects on switchgrass yield.

“…117 The choice of a particular harvest method needs to consider other factors, such as the economic impact on the farmers, so that the most advantageous method can be applied. 118 Mineral reduction can also be achieved by feedstock preprocessing such as separating biomass by particle size and anatomical fraction, continued by selecting the fractions with lower mineral content. 101 The effectiveness of biomass handling in managing mineral content using air classification and size fractionation in multiple feedstocks (corn stover, switchgrass, and grass clipping) has been proven because fractions with higher mineral content are usually obtained from the smallest size and lightest airclassified fractions.…”

Minerals in biomass have a significant impact on both biofuel quality and yield. This is especially true for current thermochemical biomass conversion processes. However, the roles of plant minerals in biochemical conversion have not been studied extensively, even though they are generally considered to lower the sugar yield because they reduce the feedstock proportion of carbohydrates. A successful strategic solution is thus necessary to overcome the challenges caused by the minerals in biomass, which include (1) decreased quality of biomass feedstocks; (2) reduction of process efficiency; and (3) reduction of the product quality and quantity from biomass conversion. This review summarizes the roles of plant minerals in a biorefinery, focusing on these key challenges. The discussion covers many issues related to plant minerals in biofuel production, including their sources, functions, and distribution in plant biomass, methods of characterizing them, their influence in a biorefinery, and the strategic handling required to manage their occurrence in biomass, based on reported studies. It could inspire better strategies to deal with the variance of mineral content in biomass feedstocks to increase process efficiency and reduce costs while supporting the concept of a circular bioeconomy.

“…Among the 32 papers, more than 55% were published after 2008, suggesting a growing interest in optimization analyses of LCB feedstock and biofuel supply chains. The objectives of the mathematical programming models in many studies, including more recent studies after 2011, were single objective optimizations using economic criteria such as cost minimization, net present value maximization, or profit maximization (e.g., Dunnett, Adjiman, and Shah, 2007;Kondili, Pantelides, and Sargent, 1993;Mas et al, 2010;Maung and Gustafson, 2013), whereas a few studies considered dual economic and environmental criteria in the design of a feedstock supply chain. For example, You and Wang (2011) evaluated minimum economic cost and minimum GHG emission criteria to examine the optimal biofuel supply chain as a case study in Iowa and found that efficient conversion technology was the key for commercialized LCB-based biofuel production.…”

A multiobjective optimization model integrating with high-resolution geographical data was applied to examine the optimal switchgrass supply system in Tennessee that considers both feedstock cost and greenhouse gas (GHG) emissions in the system. Results suggest that the type of land converted into switchgrass production is crucial to both plant gate cost and GHG emissions of feedstock. In addition, a tradeoff relationship between cost and GHG emissions for the switchgrass supply is primarily driven by the type of land converted. The imputed cost of lowering GHG emissions in the feedstock supply system was also calculated based on the derived tradeoff curve.Biofuel production from lignocellulosic biomass (LCB) is being advocated as an alternative to fossil-based transportation fuels in the United States. LCB-based biofuel production has the potential to mitigate greenhouse gas (GHG) emissions from the transportation sector and to enhance rural economic activity through more intense use of agricultural lands (English et al., 2006). The Renewable Fuel Standard (RFS) established in 2005 and revised in the Energy Independence and Security Act 2007 mandates 21 billion gallons of advanced biofuel (other than ethanol derived from corn starch) available for transportation use by 2022 with 16 billion gallons to be produced from LCB feedstock (U.S. Congress, 2007). Based on the recently revised One Billion Ton Update study (U. S. Department of Energy, 2011), considerable LCB feedstock, including dedicated energy crops, will be required to fulfill this goal. Notwithstanding the potential availability of LCB feedstock to meet the mandate, the cost of LCB feedstock will be an important factor influencing the sustainability of an LCB-based biofuel industrial sector.
