Description: technologyComment of borax production, anhydrous, powder (RER, RoW): Production out of sodium borates by melting technology, using a rotary kiln and a subsequent fusion furnace. The overall process yield is assumed as 98%. Input amount bases on stoechiometric calculations. The energy consumption is estimated based on filament glass production in Europe.

Comment: This is a market activity. Each market represents the consumption mix of a product in a given geography, connecting suppliers with consumers of the same product in the same geographical area. Markets group the producers and also the imports of the product (if relevant) within the same geographical area. They also account for transport to the consumer and for the losses during that process, when relevant. This is the market for 'borax, anhydrous, powder', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. 'borax, anhydrous, powder' is an inorganic substance with a CAS no. : 001330-43-4. It is called 'disodium;3,7-dioxido-2,4,6,8,9-pentaoxa-1,3,5,7-tetraborabicyclo[3.3.1]nonane' under IUPAC naming and its molecular formula is: B4Na2O7. It is solid under normal conditions of temperature and pressure and appears in odourless, crystalline form. The substance is modelled as a pure substance. On a consumer level, is used in the following products: lubricants and greases, washing & cleaning products, anti-freeze products, heat transfer fluids and adhesives and sealants. On industrial sites, the substance is used for the manufacture of products in the following sectors: building & construction work. This substance is used for the manufacture of: chemicals, mineral products (e.g. plasters, cement), machinery and vehicles, metals and fabricated metal products. This market is supplied by the following activities with the given share: borax production, anhydrous, powder, RER: 0.000768617021276596 borax production, anhydrous, powder, RoW: 0.999231382978723 generalComment of borax production, anhydrous, powder (RER, RoW): The functional unit represent 1 kg of anhydrous borax powder. Large uncertainty of the process data due to weak data on the production process and missing data on process emissions. [This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.]
