Description: technologyComment of bronze production (RoW): Assumed energy mix for melting. Abatement of air emissions assumed technologyComment of bronze production (CH): Production is basically done by melting the different metals. Due to the high vapour pressure of zinc and tin, parts of these inputs arise as air emissions. Filters are commonly used to abate these emissions.

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 'bronze', in the Global geography. In this market, expert judgement was used to develop product specific transport distance estimations. This market is supplied by the following activities with the given share: bronze production, CH: 0.00499999999999998 bronze production, RoW: 0.995 generalComment of bronze production (RoW): Stands for bronze with 95% Cu and 5% Sn. All data are calculated based on assumptions and theoretical models. Their overall quality is poor. [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.] generalComment of bronze production (CH): This dataset describes the processing of copper and tinup to production of 1 kg of molten bronze.

The overall quality of the dataset is poor, making it of insufficient quality for LCA where these metals play an important role.
