Germany's glass industry produces a wide range of different glass types that differ in their chemical composition. Germany's glass sector comprises the following sub-sectors: container glass, flat glass, domestic glass, special glass and mineral fibres (glass and stone wool). The largest production quantities are found in the sectors of container glass and flat glass. Further processing and treatment of glass and glass objects are not considered.
Information about the key source relevance can be found in 2.A Mineral Industry.

Method

The emissions are calculated via a higher Tier method resembling a Tier 2 method, as the activity rates are tied to specific emission factors for different glass types.

Activity data

The production figures are taken from the regularly appearing annual reports of the Federal Association of the German Glass Industry (Bundesverband Glasindustrie; BV Glas). "Production" refers to the amount of glass produced, which is considered to be equivalent to the amount of glass melted down.

Emission factors

The procedure used to determine emission factors for the various glass types involved and the pertinent emissions is described in detail in reports of research projects (Report-No. 001264, search "UBA-FB 001264" in [http://doku.uba.de] => OPAC => Signatur). The emission factors were calculated for the various industry sectors. The factors vary annually in keeping with industry monitoring, not only as steady trends, but as time ranges. Ranges below are given as averages over all glass types for main pollutants, but as averages over time for heavy metals:

Table 1: Overview of applied emission factors

pollutant	products	EF	unit	current Trend
NOx	all glass types	1.0-3.4	kg/t	constant
SO2	all glass types	0.39-1.9	kg/t	constant
NMVOC	all glass types	0.96	kg/t	constant
NH3	all glass types	0.03-0.7	kg/t	constant
TSP	all glass types	0.02-0.04	kg/t	constant
PM10	all glass types	0.01-0.03	kg/t	constant
PM2.5	all glass types	0.01-0.02	kg/t	constant
As	container glass	0.04-0.13	g/t	rising
Pb	container glass	0.22-0.41	g/t	rising
Cd	container glass	0.01-0.04	g/t	rising
Cr	container glass	0.03-0.07	g/t	falling
Cu	container glass	0.10-0.23	g/t	falling
Ni	container glass	0.01-0.02	g/t	erratic
Se	container glass	0.8-1.9	g/t	erratic

Trends in emissions

Trends in emissions correspond to trends of emission factors and of activity data. The resulting trends are not constant, but a complex result of different EF for various glass types.

Recalculations

Recalculations were necessary due to updated activity data for the last reported year and due to first time reporting of heavy metal emissions.

For pollutant-specific information on recalculated emission estimates reported for Base Year and 2015, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

At the moment, no category-specific improvements are planned.
