2.A.3 Glass Production

2.A.3 - Glass Production

Short description
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 key source relevance you find within the overview '2.A'.

The emissions are calculated via a higher Tier, near a Tier 2 method, because 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 (and thus time ranges are given as average over all glass types):

pollutant Name of Category EF unit current Trend
NOx glass production 1.0-2.5 kg/t falling
SO2 glass production 0.39-1.9 kg/t falling
NMVOC glass production 0.96 kg/t constant
NH3 glass production 0.03-0.7 kg/t falling
TSP glass production 0.02-0.04 kg/t constant
PM10 glass production 0.01-0.03 kg/t constant
PM2.5 glass production 0.01-0.02 kg/t constant

Trends in emissions

All trends in emissions correspond to trends of emission factors in table above. No rising trends are to identify.


Recalculations were necessary due to updated activity data for the last reported year.
