Waste Statistics 1997

4. Hazardous waste

Table 9 on hazardous waste amounts, includes waste from primary and secondary sources distributed on treatment options. Waste from secondary sources, such as waste from incineration plants, is not included in total waste generation, cf. Table 1. However, it is reasonable when assessing the total generation of hazardous waste to include waste from both primary and secondary sources.

Table 9 shows a slight decrease from 1996 to 1997 of 15,600 tonnes in hazardous waste arisings. This decrease covers different developments for different fractions. For example, an increase of 7,500 tonnes in total generation of oil and chemical waste from primary sources has been registered, whereas there has been a decrease of 10,600 tonnes in the generation of fly ash and flue gas cleaning products from waste incineration plants.

In 1996, Kommunekemi received 82,500 tonnes of oil and chemical waste, or 10 per cent less than amounts received in 1995, and the lowest amount since 1984. This trend continued in 1997, with 74,200 tonnes of oil and chemical waste delivered to Kommunekemi, corresponding to around 10 per cent less than in 1996.

This result shall be seen in connection with the fact that amounts of oil and chemical waste subjected to special treatment at other treatment plants than Kommunekemi more than doubled in 1997 compared to 1996. As mentioned above, total generation of oil and chemical waste increased by 7,500 tonnes or almost 7 per cent.

Amounts of nickel-cadmium batteries collected in 1997 were 95 tonnes against only 33.5 tonnes in 1996. This increase can be attributed to Statutory Order no. 93 of 22^nd February 1996 on Collection of Hermetically Sealed Nickel-Cadmium Accumulators (Closed Nickel-Cadmium Batteries) and Remuneration for Collection and Disposal for Recycling. Under the terms of this Statutory Order, a remuneration was introduced amounting to DKK 120/kg of nickel-cadmium batteries collected for recycling.

Since subsidies were introduced in 1993 for incineration of waste oil at district heating plants, amounts of waste oil delivered to such plants have increased steadily. In 1994 and 1995, around 19,000 tonnes were delivered, and in 1996 a delivery of 20,734 tonnes was registered, whereas 22,500 tonnes of waste oil were delivered to district heating plants in 1997.
