To oversee the study a core group of IZA members and staff were assembled to direct, review and coordinate activities associated with methodology, data collection, modeling, as well as the appropriate presentation and dissemination of the LCI results. The seven core group members and their affiliations at the time of the project were:
• Bill Adams [Rio Tinto]
• Anne Dekker [Nyrstar]
• Christian Canoo [IZA]
• Andrew Green [IZA]
• Walter Kuit/Mark Edwards [TeckCominco]
• Robert Prairie [Xstrata Zinc]
2. Allocation of burden to co-products has been already addressed within the model for this dataset. The results include credits to the zinc production system equivalent to the environmental burdens associated with the production of sulphuric acid from nonferrous sources as well for other co-products like lead, copper, silver and gold. Allocation to co-products within the precursor chains is documented within the GaBi database documentation.

Quality network: 375GLOThe primary zinc (special high grade zinc) production data set is based on data from 2005. It represents 32% of the global zinc production. The data set is created by using data representing applied technologies. These technologies are electrometallurgical smelting (90% of production) and pyro-metallurgical smelting (10% of production). It can be used for all LCI/LCA studies where special high grade zinc is needed.Unit process, single operationAttributionalnoneGaBi 4 Software and Databases32.00The data is overall of good quality. The data collected on a global basis represent state-of-the-art-of technology applied within the zinc industry. The data are based on information from 2005. Data provided represent either measured values from the participating sites or result from using emission factors e.g. emissions to air. In general, the highest quality of available data was used, with preference given to measured data. Additional information on process-specific data quality information is available upon inquiry with PE.No statementAndrew Green2019-02-01T00:00:00.000ILCD format 1.1Andrew Green2019-02-01T00:00:00.00000.00.001Data set finalised; entirely publishedNREL US Life Cycle Inventory (USLCI) LibraryVarious (NREL USLCI)trueFree of charge for all users and usesGaBi (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
