Description: technologyComment of flat glass production, uncoated (RER): Basic principle is pouring molten glass onto a bath of molten tin and forming a ribbon with the upper and lower surfaces becoming parallel under the influence of gravity and surface tension. Average technique used in European flat glas production.

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 dataset represents the supply of 1 kg of flat glass, uncoated from activities that produce it within the geopgraphy of Europe. No transportation is taken into account here as its consumption is generally considered to take place in the production site. Product losses during transportation are assumed negligible and are therefore not included. A regional market for Europe [RER] is assumed justified, due to the low share (in the range of 8.7%-16.4% of total trade quantities between 2010-2016) of import quantities to EU28 from outside (excluding Norway and Switzerland) the Union.

This market is supplied by the following activities with the given share: flat glass production, uncoated, RER: 1.0 generalComment of flat glass production, uncoated (RER): This dataset represents the production of 1 kg of uncoated flat glass.The amount of raw materials is calculated based on the composition of flat glass. The total amount of energy is partitioned in 58% from natural gas, 38% heavy fuel oil and 5% electrical. The amount of tin yearly added to the tin bath is assumed to leave the system by air, as part of the particulates. The same with lead. Both emissions are double counted: as particulate and as emission to air. Most other emissions are a mean value of plants with and plants without abatment. It is assumed that half of water evaporates and other half is treated. [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.]
