Tanning, aldehyde process

This dataset covers the aldehyde tanning route of leather to arrive at wet white leather, including all beamhouse and tannery processing steps. Environmental impacts of provision of hide are not included. Waste water emissions represent average conditions, i.e. waste water quality after treatment in a wastewater treatment plant with average removal efficiencies. The data set covers all relevant process steps / technologies over the supply chain of the represented partly aggregated cradle to gate inventory with a good overall data quality. The inventory is mainly based on industry data and is completed, where necessary, by secondary data. This data set is based on primary data from internationally adopted production processes, connected with regional precursor chains.
