General comment on data set | TYPE OF DATASET For every chemical compound three datasets are created; the unit process (partially terminated system), the non-energy and transport component of the partially terminated system, and the cumulative life cycle inventory dataset (system process). For more information and flow chart see the report (ecoinvent, 2017, Data on the Production of Chemicals created for the EU Product Environmental Footprint (PEF) pilot phase implementation, www.ecoinvent.org, ecoinvent Association, Z\xc3\xbcrich, Switzerland). This dataset represent the cumulative life cycle inventory dataset (system process). PROCESS DESCRIPTION The production volume of ethoxylated alcohols in Europe in 2000 was of 320000 tonnes per year (CESIO statistics 2000). 86% of this is estimated to be consumed in the region and the rest is exported (HERA 2002). Imports are not estimated to be significant (HERA 2002). Similar values are reported as consumed in the Union in the year 2002 (HERA 2009). The distribution between the different average numbers of EO molecules added, is taken from table 3.8 in HERA (2009). EO7 are estimated to be 38% of the total. The split between oleo and petro based ethoxylated alcohols is taken from Shah et al. (2016), the authors report 40% of production to be petrobased. Of the petrochemical based products 18 % is produced from the Ziegler process, while 82 % from the Oxo route. These shares are the ones currently used in version 3 of the ecoinvent database, Shah et al. (2016) confirm in their article that these shares are appropriate and represent the current practice. The oleobased products are produced from palm kern and coconut oil, the split between these two is assumed to be 50% each. The production represents a mix of 27% produced from fatty acid splitting, 56% produced from methyl ester on the basis of crude vegetable oil and 17% from methyl ester out of refined oil.

J Surfactants Deterg. 19(6), pp. 1333\xe2\x80\x931351 Water content of the reference product: 0.0 kg Biogenic carbon content of the reference product: 0.321663484987061 kg DATA QUALITY ASSESSMENT The data quality ratings for the datasets were determined as the average of the 5 individual ratings for Technological Representativeness, Geographical Representativeness, Time-related representativeness, Precision/uncertainty, and implementation of the End of Life Formula. The final scores for these 5 descriptors were determined by the independent, external reviewer after a discussion with the internal reviewers. The basis for this determination was generally a contribution analysis of the material and energy inputs as well as direct resource uses and emissions. This process was required by the tender. The contribution analysis is based on the most important flows in the dataset, defined in the tender specifications as \xe2\x80\x9cthe unit processes contributing cumulatively to at least to 80% of the total environmental impact based on characterised and normalised results\xe2\x80\x9d. In addition to unit processes, direct emissions also qualified as input exchanges for this approach. For the normalization, the normalisation factors \xe2\x80\x9cEC-JRC Global (2010 or 2013), per person\xe2\x80\x9d available at http://eplca.jrc.ec.europa.eu/?page_id=140 were used. For each parameter, the DQR scores were chosen to best reflect the conditions and quality of the amount value, the appropriateness of the chosen exchange for the specific needs of the system under analysis, and the quality of the foreground and background data for aggregated inputs of exchanges from the technosphere, i.e. not direct emissions or resource uses. ENERGY AND TRANSPORT INFORMATION SOURCE Energy and transport was used in both the foreground and background of this dataset. When building the dataset, energy and transport demands were supplied directly by datasets provided by thinkstep. The background for every other input from technosphere uses a modified version of the ecoinvent database, created specifically for the PEF. In this version, every instance of energy and transport supply, anywhere in the database, was replaced by a dataset from thinkstep. This ensures that every demand for energy and transport, in the foreground and in the background, is supplied by a thinkstep dataset. BILL OF MATERIALS The bill of material includes the following inputs: fatty alcohol: 0.416 kg chemical factory, organics: 4e-10 unit ethylene oxide: 0.556 kg nitrogen, liquid: 0.019 kg tap water: 0.026 kg wastewater, average: -2.7e-06 m3 Electricity: 0.0676810844106 kWh Thermal energy (MJ): 0.834646632707 MJ. NOT INCLUDED EXCHANGES The following exchanges have not been included in the inventory as they are not part of the official list of elementary exchanges published by the JRC. The EC and JRC were not able to provide an extended flow list during the duration of the data creation. If the JRC decides to include these exchanges in the master data, they may be added to the exchange section of the dataset by ecoinvent as part of a maintenance. The absence of these exchanges does not change the scores calculated with the ILCD recommended methods, but that might not be the case for other LCIA methods.

Technology description including background system | Alcohol ethoxylates (AE) are produced by the reaction of fatty alcohols with ethylene oxide leading to a condensation of polyethylene glycolether groups on the alcohol chains. The fatty alcohols can be derived from petrochemical, palm kernel, or coconut oil. The reaction takes place at temperatures ranging from 150\xc2\xb0C to 200\xc2\xb0C. The grade of ethoxylation, e.g. the specific number of polyether units condensed to the alcohol chains, is controlled by the concentration of ethylene oxid in the ethoxylation process. |

Modelling constants | All modelling constants follow the requirements listed in the Tender Specifications ENV.B.1/SER/2016/0038vl. Completeness: All known environmental flows are included. All known resource uses and emissions are listed in the inventory. Water use: water use is modelled at country level using separate flows for water withdrawal, water release and water evaporation. Cut-off: All known environmental flows are included. All known resource uses and emissions are listed in the inventory. Handling multi-functional processes: the following PEF multi- functionality decision hierarchy is applied for resolving all multi- functionality problems: (1) subdivision or system expansion; (2) allocation based on a relevant underlying physical relationship (substitution may apply here); (3) allocation based on some other relationship. Direct land use change: GHG emissions from direct LUC allocated to good/service for 20 years after the LUC occurs, with IPCC default values. Carbon storage and delayed emissions: credits associated with temporary (carbon) storage or delayed emissions up to 300 years are not be considered. Emissions off-setting: are not included. Capital goods (including infrastructures) and their End of life: they are included. System boundaries: system boundaries include all processes linked to the product supply chain (e.g. maintenance). Time period: emissions and removals are modelled as if released or removed at the beginning of the assessment method. Fossil and biogenic carbon emissions and removals: removals and emissions are modelled as follows: All GHG emissions from fossil fuels (including peat and limestone) are modelled consistently with the most updated ILCD list of elementary flows. The non-fossil (biogenic) carbon flows are modelled consistently with the most updated ILCD list of elementary flows. | ||||||||||||||||||||||||||||
