2.D.3.i - Other Solvent Use

This category is a key source of NMVOC emissions in terms of emissions level and trend.
In source category 2.D.3.i - Other Solvent Use, emissions from various product groups and processes are reported. Relevant pollutants are NMVOC and some heavy metals.

Emissions from lubricants use in stationary and mobile applications were reported here just to the submission 2023. For the actual submission emissions of all lubricants use are reallocated to 2.G.4 due to a NECD review recommendation.

In sub-category 2.D.3.i - Other product use: Other solvent use the following product groups and processes are taken into consideration:

• Glass and mineral wool enduction (SNAP code 60401/02)
• Fat, edible and non-edible oil extraction (SNAP code 60404)
• Application of glues and adhesives (SNAP code 60405) (paper and packaging; wood; footwear; transport; Do-it-yourself-applications; others)
• Preservation of wood (SNAP code 60406)
• Underseal treatment and conservation of vehicles (SNAP code 60407)
• Vehicles dewaxing (SNAP code 60409)
• Other: (SNAP code 60412)
  • Plant protectives
  • Dichloromethane in strippers
  • Removal of paints from incorrectly coated aluminium parts
  • Removal of paint from steel parts
  • Concrete additives
  • De-icing (Aircraft de-icing; De-icing of operated areas; Other de-icing applications)
  • Applications in scientific laboratories (R&D; analyses; universities)

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 category 2.D.3.i, which accounts for about 12 to 26 % of total NMVOC emissions from solvent-based products.

The following product groups cause major emissions in category 2.D.3.i:

• Concrete additives,
• Underseal treatment and conservation of vehicles,
• Application of glues and additives,
• Deicing and
• Fat, edible and non-edible oil extraction

In total, these six activities account for between 88 and 93 per cent of total NMVOC emissions from 2.D.3.i.

A decrease in these NMVOC emissions can be observed since 2005 mainly due to a clearly reduced consumption of concrete additives.

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

Exceptions were de-icing applications, applications in scientific laboratories with a relative error at 25%.
