| Use advice for data set | Notice: this data set supersedes the EF3.0-compliant version (see link under "preceding data set version" below calculated with the EF3.0). The life cycle inventory is not changed from the original EF3.0 data set. The LCIA results are calculated based on the EF3.1 methods which provide updated characterisation factors in the following impact categories: Climate Change, Ecotoxicity freshwater, Photochemical Ozone Formation, Acidification, Human Toxicity non-cancer, and Human Toxicity cancer. The review report and the data quality ratings refer to the original results. The data set has been updated by the European Commission on the basis of the original EF3.0 data set delivered by the data provider. |

| General comment on data set | The dataset represents the manufacture of raw materials for the paint industry. It is based on the models created for the CEPE Raw Material database, version 3 (European Council of the Paint, Printing Ink and Artists' Colours Industry; limited access), which have been updated with PEF-compliant background sources based on Ecoinvent 3.3 and process-based EF-compliant LCI datasets for energy and transport. The inventory is based on literature and background sources, following general assumptions for the paint industry. Biogenic carbon content 0%. Water content 0% |

| Technology description including background system | In the technology description below, specific dataset names refer to the original modelling based on Ecoinvent 3.3. They might have been updated using the names of the equivalent EF-compliant datasets (In particular transport, infrastructure, water, heat, energy and waste datasets). No specific data available. The process is modelled as an average of two ester solvents with specific data available, i.e. butyl acetate and ethyl acetate: • Butyl acetate – The process "RER: butyl acetate production" is modelled for the production of butyl acetate from 1-butanol in Europe. Raw materials are modelled with stoichiometric calculations. Energy consumptions are modelled with data from a similar process. The emissions are estimated. Infrastructure and transports are calculated with standard values (Ecoinvent Centre, 2016). This production takes place via the esterification of 1-butanol with acetic acid. The production of n-butyl acetate in 1985 was about 81000 t in the USA and 30000 t in Europe. (Riemenschneider, 2004) • Ethyl acetate – The process "RER: ethyl acetate production" is modelled for the production of ethyl acetate from ethanol in Europe. Raw materials and energy consumptions are modelled with literature data. The emissions are estimated. Infrastructure and transports are calculated with standard values (Ecoinvent Centre, 2016). An aequous solution of acetic acid is mixed with ethanol; then 1% sulfuric acid is added. The mixture is preheated before passing into an esterifying column where it is refluxed and some of the distillate removed overhead. The mixture, containing about 20% of the ester, goes into a second refluxing column where a ternary azeotrope (consisting of 83% ethyl acetate, 9% ethanol and 8% of water) is removed overhead at a temperature of about 70°C. An equal volume of water is mixed with the distillate after which it separates into two layers. The bottom layer is fed into a separator column and ester is recovered as a ternary azeotrope. Any alcohol remaining in the bottom layer is vaporized and recycled to the esterification column. The upper layer, containing around 93% ethyl acetate together with some water and ethanol, passes to a refluxing column where it is mixed with sufficient ester to ensure that the water and ethyl alcohol are removed as a ternary azeotrope overhead. The residue in the column, consisting of 95% ethyl acetate, is redistilled to remove any impurities. The process leads to a yield of 99 %. (Wells, 1991) |
