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 'pumice', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. The product "pumice" represents 1 kg of pumice stone. Crushed and classified pumice is employed as an additive in light insulating concrete used to make constructional units. Due to its limited compression strength, this building material can only be used for two-storey buildings, or for cladding load-bearing frameworks. Building blocks consist of pure, natural pumice granules treated to remove organic and inorganic im-purities. They are mainly used to build houses. Powdered pumice is used as an abrasive, as a polishing medium, and as an additive to pumice soap. It is also used as an absorption medium due to its large surface area (e.g., in packages carrying breakable liquid containers). This market is supplied by the following activities with the given share: pumice quarry operation, DE: 0.0605146238179278 pumice quarry operation, RoW: 0.939485376182072 generalComment of pumice quarry operation (DE, RoW): For a lack of data the dust emissions for bauxite mining are used as proxy. Further following proxys have been used: The amount of water has been copied from the water consumption in "sand, at mine"-wasing and for heating the "light fuel oil"-heating module has been used. [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.]
