7.1 Incineration plants

In 1996, total waste incineration capacity was 2,474,000 tonnes, distributed on 31 plants, cf. Table 17. In the beginning of the nineties, an extensive conversion of waste incineration plants from heating generation to combined power and heating generation took place. In this connection, capacity adjustments were effected in relation to expected waste amounts for incineration in future.

As a result of the ban on landfilling of waste suitable for incineration that took effect on 1^st January 1997, increased pressure on incineration capacity is expected. Amounts of non-recyclable waste suitable for incineration will be surveyed regularly in order to ensure necessary incineration capacity.

Table 17. Number of incineration plants and available incineration capacity in 1989, 1993, 1994/95 and 1996	1989	1993	1994/95	1996
Number of incineration plants	38	31	31	31
Theoretic capacity, ‘000 tonnes	2164	2329	DH: 1217 CPH: 1315	DH: 1060 CPH: 1413
Nominal capacity, tonnes/hour	313	335	DH: 174 CPH: 188	DH: 171 CPH: 194

The Danish Environmental Protection Agency and the Danish Energy Agency 1997: Waste amounts for incineration year 2000. Figures for 1989 and 1995 are calculated on the basis of nominal capacity at 7,000 hours/year. Figures for 1996 are based on actual hours of operation of plants. District heating capacity (DH) may be subject to restrictions under the Act on heating supply. CPH = combined power and heating.

7.2 Landfills

Total remaining capacity at landfills in 1994 amounted to 24.7 million tonnes distributed on 64 sites. Remaining capacity at landfills for inert waste in 1994 was 6.4 million tonnes distributed on 49 sites. Remaining capacity at separately located mono-landfills amounted to 6.2 million tonnes in 1994, distributed on 63 sites.

A landfill is defined as a site receiving waste that, immediately or over time, presents a risk of pollution of groundwater, surface water and/or air. A landfill for inert waste is a site receiving waste that does not, or only to a very limited extent presents a risk of pollution of groundwater, surface water and/or air. A mono-landfill is a site receiving only one or a limited range of waste types with known composition.

As a consequence of the above-mentioned ban on landfilling of waste suitable for incineration, in combination with an increased and further differentiated waste tax, a drop in landfill capacity needs is expected. Thus, at the national level, it is not expected that there will be a need for large extensions of landfill capacity in future.

Remaining capacity, million tonnes	30.9	24.7	14.3	6.7	6.2
