NMVOC Emissions from Solvent Use in Germany: Parties, Perspectives, and Discussion

This article discusses the projected NMVOC emissions from the solvent use sector in Germany, including methodology for calculation and projections, relevant source groups, emission factors, and the impact of legislation. The conclusion highlights the expected decrease in emissions due to current legislation, as well as projected emissions for 2010 and 2020.

  1. Parties perspectives and discussionProjected NMVOC emissions from thesolvent use sector in Germany Jochen Theloke University of Stuttgart

  2. Agenda • Introduction • Methodology for emission calculation • Results • Methodology for emission projections • Results • Conclusion

  3. Emissions from solvent use are the largest source group of NMVOC in Germany Source: Umweltdaten Deutschland (2005: 1128 kt) & National Plan for NEC midterm review (2010: 987 kt)

  4. Solvent Use • Application of solvents • Application of solvent containing products • Production of solvent containing products • Application of Propellants (Propane/Butane) • Extraction of fat, edible and non edible oil (n-hexane) • Cooling agents • Softening agents (Phtalates) • Concrete additives • Application of thinners

  5. Solvent relevant Source groups • Paint application • Printing application • Application of glues and adhesives • Degreasing processes • Plastics and rubber processing • Manufacturing of solvent content products • Domestic solvent use • Frost protection and deicing agents • Aerosolsprays • Other applications About 100 different solvent related activities are considered in the German inventory

  6. Emission calculation methodology Emission = Inland consumption x solvent content x emission factor Product-related calculation methodology – The calculation is on base of public available data operable

  7. Example: Paint Application • Identification of relevant Product groups: • Water based paints and varnishes • Solvent based paints and varnishes • Powder varnishes • Thinners for application • Other thinners • Assignment of the Product groups to the Systematic of the Productions statistic • Assignment of the systematic of the production statistic to the Foreign trade statistic systematic • Linkage between Inland consumed specific product to specific application field (from German Paint Association)

  8. Example: Paint application

  9. Example: Paint application Application of specific solvent content

  10. Emission from paint application in Germany 2005 (Sum: 346 kt)

  11. Solvent emissions Germany 2005 (sum: 743 kt)

  12. Emissions from printing processes in Germany 2005 (sum: 95 kt)

  13. NMVOC emissions from domestic solvent use (sum: 69 kt)

  14. Calculation of projected emissions for future years • Scenario „ Constant Emission factors“ • Assignment of Source groups to activity indices • Application of activity indices to emissions 2005 (Constant Emission factors assumed) • Reference scenario (CLE) • Estimation of capture grades of the solvent directive • Calculation of abatement grade through the solvent directive on base of the limit value for diffuse emissions • Estimation of abatement effect of the DECOPAINT“- Directive on base of the defined solvent contents

  15. 31. BImSchV (National solvent directive) National Implementation of the EU-Directive 1999/13/EC • Installation-related • 19 application areas captured above a defined yearly solvent consumption (solvent bilance) • Defined emission limits for captured und diffuse emissions • Reduction plan •  Legislation for old installations since 01. Nov 2007 • Legislation for new installations since 01. Nov 2004 • Abatement potential for Germany about 151 kt/a Abatement level [-] = Limit for diffuse Emissions [%] / Emission factor 2005 [%]

  16. Example for determination of the capture grade Source: Jepsen et al., UBA-Research Report, 1999

  17. „DECOPAINT“-Richtlinie • EU-Directive 2004/42/EG („DECOPAINT“-Directive) • Product related • 12 different Paint- und Varnish categories captured • Maximum Solvent content defined • Declaration requirements • Implementation in two stages until 2010 • First stage from 01. Jan 2007 • National Implementation: Chemikalienrechtliche Verordnung (since 23.December 2004 legislation) • Abatement potential about 26 kt/a Abatement level 2010 [-] = solvent-cont. (max., 2010)[g/l]/(solvent cont. (2005) [g/kg]*Density[kg/l])

  18. Reference scenario 2010

  19. Emissions from solvent use will be also the largest source group of NMVOC in 2020 in Germany Source: Umweltdaten Deutschland & National Plan for NEC midterm review (1051 kt)

  20. Conclusion • Germany calculate the emission from solvent use on base of a product related method => Emissions in 2005 : 743 kt from 100 different applications fields • The projections are done on base of economic indicators and estimated impacts of current legislation • The abatement effect of solvent directive until 2010 will be decreasing the solvent emissions in Germany of about 17% (151 kt) • For the implementation of the „DECOPAINT“-Directive is estimated a further decrease of 3% (26 kt) of solvent emissions until 2010 • In 2010 for the CLE-Scenario emissions from solvent use sector of are projected of about 686 kt • For 2020 are 800 kt projected in the CLE-Scenario • That means the NMVOC emissions will slightly increase from 2010 to 2020 (CLE-Scenario) in Germany

  22. Formulas for Reference scenario E Reference scenario, 2010 = E 2005 x Ai x (1-EG x MG) E2000 : Emissions for 2005 Ai : Aktivity index 2020/2005 EG : Capture grade of the solvent directive MG : Abatement potential of the solvent directive AG=EF2010/EF2005 EF2005 : Emission factor for 2005 EF2010 : Maximum limit value for diffuse emissions defined by the solvent directive
