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 'vermiculite', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. The product "vermiculite" represents a mineral. It is mined, and used as raw material for expanded vermiculite production. Vermiculite is utilized in the construction industry for thermal and sound insulation. This market is supplied by the following activities with the given share: vermiculite mine operation, ZA: 0.40268905950096 vermiculite mine operation, RoW: 0.59731094049904 generalComment of vermiculite mine operation (ZA, RoW): For a lack of data the dust emissions for bauxite mining are used as proxy. No recultivation is assumed. To account for the phosphate mined together with the vermiculite, the resource "phosphorus, 18% in apatite, 12% in crude ore, in ground" is inventoried. Since the apatite is dumped but afterwards used by other companies it is neither considered co-product nor waste. The paraffin fueled heating system is approximated with "light fuel oil, burned in industrial furnace 1 MW, non-modulating". For the electricity mix the UCPTE-mix has been used.

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.]
