Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
Green liquor is an inorganic substance and it is not biodegradable in a sense of microbiological utilization as a source of carbon and energy. In favourable environmental conditions, the constituents may still be subject to biologically mediated processes leading to biotransformations. Carbonates and inorganic sulfur anions take part in the natural biogeochemical cycles of carbon and sulfur. The sulfur cycle and carbon cycle are of major importance to aquatic and terrestrial life. These cycles consists of biological (and abiotic) processes that transforms the elements to meet the purpose and needs of the target organisms. These cycles transfer, degrade and transform speciation of the inorganic constituents by characteristic way and depending on local environmental conditions. Anthropogenic emissions of GL constituents in to the environment will be inevitable affected by these natural cycles. Green liquor does not contain any constituent which could be regarded nontransformable (persistent) in the environment. Quantitative estimates of transformation rates is often hard to give. Transformation rates are related to environmental compartment, local environmental conditions, geographic area and season. However, after sufficient dilution and neutralization, no difference can be made whether it is question of anthropogenic sources or natural background levels of these constituents.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
