Ozone depleting substances and the greenhouse gases HFCs, PFCs and SF₆

3 Ozone-depleting substances

All known importers of ODSs responded to the questionnaire survey. The responses provide information on imports/exports, sales/purchases, and areas of application relating to relevant substances (including both mixed and pure substances). All ODSs reported by the importers are new ODSs.

The information from importers is supplemented with statistical information from Statistics Denmark for 2002. Information on CFC-11, CFC-12, CFC-113, tetrachloromethane, 1,1,1-trichloroethane, and methyl bromide regarding imports and exports is available from Statistics Denmark, but for HCFCs, halons and other CFCs, the statistics are provided only for groups of substances and not for individual substances. Therefore, Statistics Denmark cannot be used as a source for these substances. Statistical data is used for cross-checking information on imports. The statistics do not distinguish between new and re-used substances, and thus imports could, in principle, consist of both new and re-used substances. It is therefore assumed that, in imports of CFC-113, the difference between data from importers and data from Statistics Denmark derives from imports of re-used ODSs.

There are no imports for feedstock except for methyl bromide.

None of the exported amounts of HCFC-22 and HCFC-141b are used for feedstock or for "essential use". It has not been possible to quantify in detail the export of 1,1,1-trichloroethane but it has been assumed that none is used for essential use or for feedstock purposes.

The foreign trade statistics for 2002 assign the following ozone-depleting substances to the following separate positions:

• CFC-11 (position no. 2903.41.00)
• CFC-12 (position no. 2903.42.00)
• CFC-113 (position no. 2903.43.00)
• CFC-115 (position no. 2903.44.90)
• Tetrachloromethane (carbon tetrachloride) (position no. 2903.14.00)
• 1,1,1-trichloroethane (methyl chloroform) (position no. 2903.19.00)

The foreign trade statistics also include some substance group positions that can indicate trends in imports and exports of HCFCs (and HFCs and PFCs, etc.), but due to the broad definitions of the substance groups it is not possible to utilise the position numbers in the evaluation since this relates to individual substances.

In the case of CFCs, Statistics Denmark does not distinguish between new and re-used CFCs. Data on CFCs from Statistics Denmark are therefore not used in the evaluation. The Statistics Denmark information can only be used for halons, tetrachloromethane, and 1,1,1-trichloroethane when making direct comparisons with information from importers and user enterprises.

3.1 Imports and exports

The following sections describe imports and sales of individual ozone-depleting substances.

3.1.1 CFCs

The sales of new CFCs in 2002, based on information on imports were 0.95 tonnes. In 2001, sales were 2.6 tonnes. This reduction is mainly due to a particular importer reporting, in 2002, that there are no longer any imports due to changes in the market.

Three importers report sales of 0.95 tonnes of CFC-113 for laboratory purposes.

Statistics Denmark registered imports of 20 kg of CFC-113 in 2001.

There is no other information available for imports of other CFCs.

3.1.2 Tetrachloromethane

In 2002, three importers reported imports and sales of a total of 0.87 tonnes of tetrachloromethane for laboratory purposes. In 2001, imports totalled 1.25 tonnes.

Statistics Denmark registered imports of 292 kg in 2002.

3.1.3 1,1,1-trichloroethane

In 2002, two importers reported imports and sales of approx. 20 kg of 1,1,1-trichloroethane.

Statistics Denmark registered imports of 4.1 tonnes in 2002.

3.1.4 Halons

No information has been received regarding imports of halons in 2002.

3.1.5 Methyl bromide

Methyl bromide was only imported for feedstock in 2002.

3.1.6 HCFCs

Five enterprises have imported HCFCs in 2002.

The consumption of HCFC-22 and HCFC-141b has fallen, and there has been no consumption of HCFC-142b.

In 2002, imports of HCFC-22 (new and regenerated) totalled approx. 178 tonnes, of which 5.5 tonnes came from HFC mixtures. Re-exports were approx. 148 tonnes, ie. net imports of HCFC-22 in 2002 were approx. 30 tonnes, of which 24.5 tonnes were imported as pure HCFC-22. In 2001, the consumption of HCFC-22 after re-exports was 249 tonnes.

Imports of HCFC-141b totalled 360 tonnes in 2002. In 2001, imports totalled 609 tonnes.

There were no imports of HCFC-142b in 2002. In 2001, imports totalled 15.8 tonnes.

Table 3.2 shows an overview of the Danish consumption of HCFCs by application area, using information provided by importers and producers.

3.1.7 Treatment

Denmark has two treatment facilities for processing ODSs - Kommune Kemi (KK) and Århus Genindvinding. All ODSs to be treated are sent to these plants.

The KK plant does not operate a registration system for individual substances because it receives and treats all substances in mixed tanks. Consequently, it is not possible to quantify the amounts of substances collected for treatment based on what the plant receives. Therefore, information is used from importers that receive and send on used ODSs for treatment at the KK plant.

The Århus Genindvinding plant can document specific annual quantities of individual substances processed at the plant.

The ODSs treated in 2002 appear from the table below.

Table 3.3 Treated ODSs in 2002, tonnes

Some of the HCFC-22 results from HFC mixtures (HFC-401a, HFC-402a, HFC-403a, HFC-408a, HFC-409a and HFC-502a) that are sent by Danish importers to the Kommune Kemi treatment plant for processing either as mixtures of pure refrigerants or in mixture cylinders.
