2.D.3.a Domestic solvent use including fungicides** NMVOC T2 NS CS NMVOC (L/T)

This source category comprises NMVOC emissions from the use of solvent-based products in domestic applications excluding paints and lacquers. (The latter products are included in source category 2.D.3.d).

The following product groups are taken into consideration:
i) Domestic solvent use

  • Soaps
  • Laundry detergents, dishwashing detergents and cleaning products (fabric softeners; universal detergents; washing agents; auxiliary washing preparations; dishwashing liquids; detergents for dishwashers; floor detergents; carpet shampooers; car cleaning shampoos; glass cleaners; WC cleaners)
  • Care products for footwear, leather articles, furniture, floors and cars
  • Polishing agents (for metal)
  • Deodorizers (for rooms and others)
  • Perfumes (after shaves; eau de toilette, perfumes)
  • Cosmetic and make-up preparations (make-up; hand care products; nail care products; pedicure products; face cleanser; suntan lotions; face and body care products and others)
  • Shampoos and hair care products (shampoos; preparations for permanent waving or straightening; hair sprays; lotions and brilliantines; toning shampoos; hair colouring products; hair bleaching and other)
  • Other personal care products (shaving creams; personal deodorants and antiperspirants; bath essences; depilatories, deodorants, preparations for intimate hygiene and other)
  • Antifreeze agents for cars

ii) Domestic use of pharmaceutical products

‘NMVOC’ is defined in keeping with the VOC definition found in the EC solvents directive. For purposes of the definition of solvents, the term ‘solvent use’ is also defined in keeping with the EC solvents directive.

Method

General procedure

NMVOC emissions are calculated in keeping with a product-consumption-oriented approach.

In this approach, solvent-based products or solvents are allocated to the source category, and then the relevant NMVOC emissions are calculated from those solvent quantities via specific emission factors. Thus, the use of this method is possible with the following valid input figures for each product group:

  • Quantities of VOC-containing (pre-) products and agents used in the report year,
  • The VOC concentrations in these products (substances and preparations),
  • The relevant application and emission conditions (or the resulting specific emission factor).

The quantity of the solvent-based (pre-)product corresponds to the domestic consumption which is the sum of domestic production plus import minus export.

NMVOC Emission = domestic consumption of a certain product * solvent content * specific emission factor

The calculated NMVOC emissions of different product groups for a source category are then aggregated.

The product / substance quantities used are determined at the product-group level with the help of production and foreign-trade statistics. Where possible, the so-determined domestic-consumption quantities are then further verified via cross-checking with industry statistics.

Specific information

Calculation of domestic consumption was based on:

  1. the German production statistics and external trade statistics for the subgroup “Domestic solvent use”.
  2. turnover values of pharmaceuticals produced in Germany for the subgroup “Domestic use of pharmaceutical products”,

Solvent contents for this product group correspond to personal information from industrial associations and German literature.1

For alcohol-based cleaning detergents an emission factor of 3% was assumed for calculations2 For all other products of this source category (e.g. hair spray, after shave, perfumes), an emission factor of 95% was applied.

Discussion of emission trends

General information

Since 1990, so the data, NMVOC emissions from use of solvents and solvent-containing products in general have decreased by nearly 38%. The main emissions reductions have been achieved in the years since 1999. This successful reduction has occurred especially as a result of regulatory provisions such as the 31st Ordinance on the execution of the Federal Immissions Control Act (Ordinance on the limitation of emissions of volatile organic compounds due to the use of organic solvents in certain facilities – 31. BImSchV), the 2nd such ordinance (Ordinance on the limitation of emissions of highly volatile halogenated organic compounds – 2. BImSchV) and the TA Luft.

Specific information

Until 1999, data of the present source categories 2.D.3.a, 2.D.3.h and 2.D.3.i were treated as one source group. Since 2000, a more detailed data collection enables to follow the development of source group 2.D.3.a, which accounts for about 10 – 12% of total NMVOC emissions from solvent-based products (Figures 1-3).

Figure 3: Share of NMVOC emissions from source groups 2.D.3.a, h, i on total NMVOC emissions from solvent-based products and applications since 1990.

Only a slight decrease in the overall NMVOC emissions can be observed since 2000. Table 1 lists four products groups that cause major emissions in category 2.D.3.a: hair sprays, antifreeze agents for cars, eau de toilette and pharmaceutical products.

Major emissions from … 2001 2006 2007 2008 2009 2010 2011 2012 2013
Hair sprays3 29% 7% 10% 25% 18% 12% 14% 17% 15%
Antifreeze agents for cars 11% 31% 29% 21% 24% 37% 24% 16% 22%
Eau de Toilette 8% 10% 11% 3% 7% 9% 11% 16% 10%
Domestic use of pharma-ceutical products 4% 10% 10% 11% 10% 9% 11% 11% 10%

Table 1: List of product groups that primarily contributed to NMVOC emissions of category 2.D.3.a. The table presents the share of emissions on total emissions of this source group. These four product groups comprise together 50 – 70% of total emissions depending on the considered year. Semi-aggregated data from 2002 until 2005 do not allow calculating shares for the listed product groups in this period.

As emission factors and solvent contents largely remained robust since 2000, domestic consumption of products caused visible changes in NMVOC emissions. For instance, the amount of used ‘antifreeze agents for cars’ per year primarily depends on the weather situation of the specific year. As antifreeze agents have one of the highest domestic consumption values of the category ‘domestic solvent use’, they significantly influence the final value of emitted NMVOC of this category. The increase in emissions of 2.D.3.a in 2010 can be majorly explained by a long-lasting cold season and the need for antifreeze agents.

Major emissions from … 2001 2006 2007 2008 2009 2010 2011 2012 2013
Hair sprays4 100% 18% 25% 64% 52% 41% 40% 47% 43%
Antifreeze agents for cars 100% 179% 181% 124% 164% 304% 162% 104% 117%
Eau de Toilette 100% 89% 103% 25%5 73% 109% 116% 152% 89%
Domestic use of pharma-ceutical products 100% 207% 217% 217% 235% 246% 241% 238% 230%

Table 2: List of product groups that primarily contributed to emissions of category 2.D.3.a and their relative development compared to 2001. Semi-aggregated data from 2002 until 2005 do not allow calculating shares for the listed product groups in this period.

The domestic consumption and hence NMVOC emissions decreased for some products such as hair sprays, personal deodorants and antiperspirants, after shaves and car surface protectants, compared to the years 2000 and 2001. However, domestic consumption and hence NMVOC emissions increased for other product groups, such as soaps and pharmaceutical products in the same period. The simultaneous increase and decrease of NMVOC emissions for different product groups and seasonal variations are causes for an only minor decrease in recent years and greater fluctuations.

Uncertainty

Uncertainties for emissions for each product were obtained by error propagation and refer to the 95% confidence interval.

Domestic Consumption:
For all values based on the official statistics, a relative uncertainty of ±10% was applied. (An exception is the complex value for ‘antifreeze agents for cars’ at ±20%.)
Solvent content:
For each product, a relative error at ±15% was applied, but not exceeding 100% or falling below 0%.
Emission factors:
For each product, a relative error at ±15% was applied, but not exceeding 100% or falling below 0%. (An exception is the value for ‘antifreeze agents for cars’ at ±25% based on expert estimation.)

Hence the overall uncertainty of emissions caused by application of products of this source group is 40% with exception of ‘antifreeze agents for cars’ at 60%.

Recalculations:

An error in calculation of the domestic consumption of hair sprays for the years 2010 and 2011 was corrected.
