Unit process data for lignin extraction in a softwood kraft pulp mill

    This unit process represents the gate-to-gate production of 1 air-dried metric tonne of kraft lignin, coproduced with southern bleached softwood kraft pulp (SBSK), high voltage electricity and unrefined tall oil soap. The pulp is derived from pine or loblolly pine in a kraft pulping process at a mill in the southern United States (U.S.). Lignin is extracted via precipitation and acid washing. All flows are production weighted to kraft lignin. The SBSK pulp production technologies are an aggregation of those applied in the southern U.S. in 2013.

    Feedstock Readiness Level Instructions, Checklist, and Report Template for Evaluations

      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. This document contains instructions, checklists for crops and for woody materials and residues, and a template for the report, as well as examples.

      Feedstock Readiness Level (FSRL) evaluation: Pennisetum purpureum (napier grass), Alcohol-to-Jet, Southeast, Sept. 2016

        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 September 2016, assesses the maturity of *Pennisetum purpureum* (napier grass), as a feedstock for the Alcohol-to-Jet conversion process in the United States Southeast region.

        Feedstock Readiness Level (FSRL) evaluation: Panicum virgatum (switchgrass), Alcohol-to-Jet, Southeast, Sept. 2016

          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 September 2016, assesses the maturity of *Panicum virgatum* (switchgrass) as a feedstock for the Alcohol-to-Jet conversion process in the United States Southeast region.

          Feedstock Readiness Level (FSRL) evaluation: Miscanthus x giganteus (giant miscanthus), Alcohol-to-Jet, Southeast, Sept. 2016

            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 September 2016, assesses the maturity of *Miscanthus x giganteus* (giant miscanthus) as a feedstock for the Alcohol-to-Jet conversion process in the United States Southeast region.

            Feedstock Readiness Level (FSRL) evaluation: Brassica napus (Canola), hydroprocessed esters & fatty acids (HEFA), Southeast, Sept. 2016

              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 September 2016, assesses the maturity of *Brassica napus* (Canola) as a feedstock for the Hydroprocessed Esters and Fatty Acids (HEFA) conversion process in the United States Southeast region.

              Product system model for distributed renewable syngas production

                This product system model represents the generation of two co-products from forest or wood product mill operation residues using the Tucker Renewable Natural Gas (RNG) Thermochemical conversion process. The two co-products are a synthesis gas (syngas) and biochar (a form of charcoal made from woody biomass via pyrolysis, used as a soil amendment, and under investigation as an approach to carbon sequestration to produce negative carbon dioxide emissions). Data for this process were collected in St. Regis, Montana and Locust, NC, where the Tucker RNG conversion process has been tested and demonstrated.

                Unit process data for bio-jet fuel production from poplar biomass via bioconversion at a biorefinery

                  A partial Life Cycle Assessment (LCA) is conducted to investigate the life cycle impacts of a biorefinery designed to convert poplar tree chips into jet fuel via fermentation and subsequent hydrogenation. The goal of producing jet fuel from Populus (poplar) trees (bio-jet) is to create an alternative to petroleum based jet fuel (petro-jet). Currently no jet fuel producing biorefineries are in commercial operation and the results of this LCA will be used to assess a potential environmental impact that could result from scaling up the proposed system. Work is part of the Advanced Hardwood Biofuels Northwest project.

                  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.
