General comment 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
This activity represents the production of 1 kg of liquid aniline. Aniline is a colourless oily liquid of a sweet, amine-like odour, and becomes brown when in contact with air and light. Aniline is used as an intermediate in many different fields of application such as, isocyanates, rubber processing chemicals, dyes and pigments, agricultural chemicals and pharmaceuticals. In the plastics industry, aniline is used for the production of methylene diphenyl diisocyanate (MDI). Aniline is mostly synthesised by hydrogenation of nitrobenzene.
The activity starts when the raw materials enter the process.
This activity ends with the production of 1 kg of aniline. The dataset includes the raw materials and chemicals used for production, estimated emissions to air and water from production (incomplete), as well as estimated energy demand and infrastructure of the plant (approximation). Solid wastes are omitted.

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:
chemical factory, organics: 4e-10 unit
hydrogen, liquid: 0.07 kg
nitrobenzene: 1.33 kg
nitrogen, liquid: 0.019 kg
tap water: 0.026 kg
wastewater, average: -2.7e-06 m3
Electricity: 0.433729354807 kWh
Thermal energy (MJ): 2.80202798123 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.
