Description: technologyComment of bentonite quarry operation (DE, RoW): The technology used in the modelled German mine is probably state-of-art (first mining company in Europe taking part at an eco-audit based on EG-eco-audit requirements). The assumed thickness of the bentonite layer is 3 m. The thickness of overburden material is estimated to be 30 m. Digging and transportation is made by heavy diesel machines.

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 'bentonite', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. The product "bentonite" represents an industrial mineral with a high content of swellable threelayer clay minerals, which often originates from the transformation of volcanic ashes and tuffs. Bentonite is used for the production of activated bentonite. This market is supplied by the following activities with the given share: bentonite quarry operation, DE: 0.0222085132634176 bentonite quarry operation, RoW: 0.977791486736582 generalComment of bentonite quarry operation (RoW): This dataset represents the production of 1 kg of bentonite. Bentonite is an industrial mineral with a high content of swellable threelayer clay minerals, which often originates from the transformation of volcanic ashes and tuffs. Bentonite is used for the production of activated bentonite. The production volume of bentonite amounted to 12.04 million metric tons in 2013 (Virta 2015). This dataset is based on information published in an environmental report by a German company (Süd-Chemie AG).
