| 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 12,1%. Water content 50% |

| 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). For this RM no specific data was found, therefore, it was modelled as described in Gooch, 2002, in which the alkyd (in 50 wt% white spirit) is emulsified in 48% water and 4 wt% emulsifying agent (75% nonylphenoxypoly, 25% dodecyl sodium sulphate). However, since LCI-data for the emulsifying agent was missing it was therefore neglected in the model. For the modelling, the data set from Ecoinvent “RER: alkyd resin production, long oil, product in 70% white spirit solution state”, was used, which was modified according to the above amounts, and to use soya oil instead of long oil. 0.05 MJ/kg electric energy was added during the emulsification step in the model. When no data regarding amount of electricity use was found, a default value of 0.05 MJ electric power/kg product per process step was used for calculations. Process steps can be e.g. mixing or pumping. This value was derived from studying LCA data of different plastics and chemicals and theoretical calculations of energy use. For the entire product chain, values are often between 0.5-2 MJ/kg plastics (incl. different steps and upstream use), making 0.05 MJ/kg a conservative estimate for one process step. Process description: The dataset “RER: alkyd resin production, long oil, product in 70% white spirit solution state” models the commonly used solvent process. It assumes the use of soybean oil as fatty acid, phthalic anhydride as polybasic acid and Pentaeritol as polyol. Activities include the transport of raw materials and production of resin. Packaging is neglected. |
