Limestone - crushed - for mill (limestone production - crushed - for mill)

Emission factor summary

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. The product "limestone crushed for mill" represents a naturally occurring mineral that consists principally of calcium carbonate but may also contain magnesium carbonate as a secondary component. It is found in many forms and is classified in terms of its origin chemical composition structure and geological formation. Limestone occurs widely throughout the world and is an essential raw material for many industries. Limestone is generally used for construction cement quicklime agriculture metal refining and flue gas desulphurisation: Construction: Limestone is the most widely used crushed rock although it is generally sold in form of sand and gravel. Cement: The production of cement is the main use for chalk and a major use for dense high-calcium limestone. Quicklime: Approximately 1.8 t of limestone is required per 1.0 t of quicklime. Agriculture: Many crops grow best under neutral to slightly acid conditions (i.e. pH between 6 and 7). Thus soils which are more acidic than pH 6 generally benefit from the application of limestone. Metal refining: When limestone is used in metal refining it is initially converted to quicklime which reacts with acidic oxides (e.g. SiO2 Al2O and Fe2O3) to produce molten slag. Flue gas desulphurisation: A growing use of limestone is in the treatment of flue gas from combustion processes to remove sulphur dioxide. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
