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 market is representing local market for gravel in Switzerland. Almost all the gravel produced in Switzerland is also sold and used in Switzerland. According to Swiss Impex database (www.swiss-impex.admin.ch, accessed 20150119) 6.023E+09 kg of gravel has been imported to Switzerland from other European countries (Swiss-Impex cathegory name; 2517.10 - Pebbles, gravel, broken or crushed stone, for concrete aggregates, for road metalling or for railway or other ballast, shingle and flint, whether or not heat-treated). The import of gravel to Switzerland should be represented by an import activity. But this activity can be build only when European production of gravel, round is present in the database. The transport distances in this market are taken from a model based on statistics on transport of goods in Switzerland (Valsasina, 2016, Default transport data per commodity group for Switzerland, ecoinvent, www.ecoinvent.org). This market is supplied by the following activities with the given share: gravel and sand quarry operation, CH: 1.0 generalComment of gravel and sand quarry operation (CH): This dataset corresponds to the production of 1 kg of sand (35%) and gravel (65%). From the total sectoral production volume (100%) of mined gravel round, crushed and sand, about 85% is gravel round and sand. [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.]
