Short description
The sub-category 1.A.2.b - Non Ferrous Metals includes aluminium production (sub-divided into primary and resmelted aluminium) as well as lead production, thermal galvanisation, copper and zinc production.
In Germany, aluminium is produced at four foundries, in electrolytic furnaces with pre-burnt anodes. The principal emission sources are resulting from fuel provided in the energy related processes.

Method
Activity data
The source of the fuel inputs consists of the statistics for the manufacturing sector (Statistik 060 - Energieverwendung des produzierenden Gewerbes / energy use in the manufacturing sector), DESTATIS, reporting number 27.43 and 27.44, production and initial processing of lead, zinc and tin, production and initial processing of copper - and, for differentiations relative to heat and electricity production, Statistik 067 (DESTATIS).
Data for fuel consumption for production and initial processing of precious metals are also provided by these statistics.
Emission factors
Reported pollutants are NOx, NMVOC, SO2, NH3 and CO.
All particulate matter emissions are reported as process emissions under 2.C.
The underlying data for the emission factors used is provided by the report on the research project "Ermittlung und Evaluierung von Emissionsfaktoren für Feuerungsanlagen in Deutschland für die Jahre 1995, 2000 und 2010" (Determination and evaluation of emission factors for combustion systems in Germany for the years 1995, 2000 and 2010"; RENTZ et al, 2002) [1]. The values for the intermediate years 1996 - 1999 and 2001 - 2010 are obtained via linear interpolation; adjusted values for the following years.
Recalculations
Recalculations were necessary for the latest reference year due to the availability of the National Energy Balance. Germany has a federal structure which causes a time lag for the National Energy Balance. Therefore recalculations are always necessary.
For pollutant-specific information on recalculated emission estimates reported for Base Year and 2016, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.
Planned improvements
At the moment, no category specific improvements are planned.
