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 'coke', in the Global geography. Transport from producers to consumers of this product in the geography covered by the market is included. coke' is a fossil fuel with a calorific value of 28.6 MJ/kg. It is used as a solid fuel and is sourced from hard coal coke furnaces. Its main applications are in the following sectors: industrial fuel. This market is supplied by the following activities with the given share: coking, DE: 0.00713214444866748 petroleum coke to generic market for coke, GLO: 0.000197765516090137 coking, RoW: 0.992670090035242 generalComment of coking (RoW): The multioutput-prozess "hard coal, in coke plant" delivers the coproducts "coke oven gas, at plant", "tar, at coke plant", and "benzene, at coke plant". 79.8% of the total energy and material input as well as emission from the coke plant are allocated to coke production, 15% to coke oven gas production, 4.1% to tar production, and 1.1% to benzene production. This allocation has been performed considering the energy content of the coke compared to all other byproducts. Due to lack of information, the allocation factors are the same as for Germany. Hypothesizing that coke production worldwide is mostly based on the byproduct process, this is described here. Emission data are maximum for US plants. Energy and material consumption as well as water emission and solid waste are taken from the DE module. The assumed uncertainty factors should somewhat frame the incomplete information about coke making outside Europe and USA. This module shall be considered only as a first approximation for the purpose to serve metal manufacturing processes within ecoinvent. In some countries coke making might exhibit worse environmental performance. Hence, when country-specific LCA studies will need to address coke making directly or indirectly, a specific assessment of local conditions should be pursued. [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.] generalComment of coking (DE): The multioutput-prozess "hard coal, in coke plant" delivers the coproducts "coke oven gas, at plant", "tar, at coke plant", and "benzene, at coke plant". 79.8% of the total energy and material input as well as emission from the coke plant are allocated to coke production, 15% to coke oven gas production, 4.1% to tar production, and 1.1% to benzene production. This allocation has been performed considering the energy content of the coke compared to all other byproducts. Hard coal coke is assumed to have a low heating value 28.6 MJ/kg and bulk density is 530 kg/m3. [This dataset was already contained in the ecoinvent database version 2.

The purpose of this activity is to link certain amount of a specific petroleum coke to the coke market, in which both products are sustitutable by another.
