Disclaimer: The LCI and LCIA results of this dataset can vary from the published Eco-profile on PlasticsEurope website due to the conversion of the original LCI to an ILCD compliant LCI, and some updates of characterization factors used in the Eco-profile since the time of the publication. This was done in agreement with PlasticsEurope. null
Salt (NaCl) recovered from various sources (rock salt, solar salt, solution-mined brine, vacuum salt) is dissolved in water and the resulting brine is purified and fed to the electrolysis unit where the brine is electrochemically decomposed into chlorine, hydrogen, and sodium hydroxide. Three different electrolysis techniques are applied: Mercury, diaphragm, and membrane cell technology.
