Product System Model for Beef Production 2011

    Product system boundaries (cow-calf-finisher, CCF) include all material and energy flows associated with crop production and live cattle operations. Cattle inventory flows include the cow-calf operation and end with market weight finisher cattle and culls resulting from one full year of operation. The total live weight produced in one year is 2914841.44 kg and is comprised of the following animals: Finished cattle: 3724 (581 kg/finisher), Culled cows: 1156 (636 kg/cow), Culled bulls: 58 (908 kg/cow). These data were developed using Integrated Farm System Model and are intended to represent the MARC cattle operation in Nebraska in 2011. The data were a product of a project funded by the National Cattleman's Beef Association.

    Feedstock Readiness Level (FSRL) evaluation: Triticum aestivum (wheat straw), Alcohol-to-Jet, Central East, May 2017

      Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in May 2017, assesses the maturity of *Triticum aestivum* (wheat straw), as a feedstock for the Alcohol-to-Jet conversion process in the United States Central East region.

      Feedstock Readiness Level (FSRL) evaluation: Herbaceous perennial grasses, Alcohol-to-Jet, Central East, Mar. 2017

        Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in March 2017, assesses the maturity of *Panicum virgatum*, *Andropogon gerardii* and *Sorghastrum nutans*, as a feedstock for the Alcohol-to-Jet conversion process in the United States Central East region.

        Feedstock Readiness Level (FSRL) evaluation: Zea mays (corn stover), Alcohol-to-Jet, Central East, Mar. 2017

          Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in March 2017, assesses the maturity of *Zea mays* (corn stover) as a feedstock for the Alcohol-to-Jet conversion process in the United States Central East region.

          Feedstock Readiness Level (FSRL) evaluation: Andropogon gerardii (big bluestem), Alcohol-to-Jet, Central East, Mar. 2017

            Feedstock readiness level evaluations are performed for a specific feedstock-conversion process combination and for a particular region. FSRL evaluations complement evaluations of Fuel Readiness Level (FRL) and environmental progress. The data from this evaluation, compiled in March 2017, assesses the maturity of *Andropogon gerardii* (big bluestem) as a feedstock for the Alcohol-to-Jet conversion process in the United States Central East region.

                Unit process data for Rapeseed production in the U.S. wheat belt

                  Unit processes represent wheat-wheat-fallow and wheat-wheat-rapeseed crop production simulations that illustrate using the IPCC (Tier 1) method for calculating changes in soil C and the roundtable on sustainable biomaterials (RSB) method for estimating N2O emissions in different locations for the use in modeling the crop production portion of the HRJ lifecycle. Data are archived in a SimaPro .csv file, which can be imported into various life cycle assessment modeling tools.
