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 'perlite', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. The product "perlite" represents a natural glass that is usually black or gray, but sometimes brownish red. It has curved shrinkage cracks, and therefore breaks up into spheroidal granules. It is usually produced by rapid cooling of rhyolitic melts (rhyolite being the volcanic equivalent of granite). Being a glass, perlite contains few crystals and has a low water content. Naturally-occurring glasses containing 3 – 8 % water are known as pitchstone. Perlite is usually used in its expanded form. This market is supplied by the following activities with the given share: perlite quarry operation, DE: 0.0605146238179278 perlite quarry operation, RoW: 0.939485376182072 generalComment of perlite quarry operation (DE, RoW): As no data are available, data from vermiculite mining are copied. Uncertainties are raised accordingly. [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.]
