1.9 million tonnes of waste from building activities

In 2012, 1.9 million tonnes of waste was generated from new constructions, rehabilitation and demolition activities in Norway. This is an increase of 18 per cent compared to 2011. The increase is caused by a higher level of activity in the construction industries.

Thirty-seven per cent (702 000 tonnes) of the total waste generated from building activities in 2012 came from rehabilitation activities. Construction activities generated 33 per cent (615 000 tonnes) and demolition generated the remaining 30 per cent (563 000 tonnes). Heavy building materials; mainly bricks and concrete, constituted about 40 per cent of the total waste. This includes 21 000 tonnes of slightly polluted concrete and bricks.

Reduction in the amounts of hazardous waste

The amount of hazardous waste is reduced compared to 2011, and constitutes about 19 000 tonnes. The main reductions come from waste containing PCBs and PCTs. Waste containing phthalates has, however, quadrupled since 2011, and makes up 14 per cent of all hazardous waste. The amount of impregnated wood is 3 870 tonnes, and this constitutes the largest share of hazardous waste. Insulating glass units containing chloroparaffins have increased from 110 tonnes in 2011 to 960 tonnes in 2012.

The data from the statistics for hazardous waste shows that some waste that is related to construction activities is associated with industries other than construction. This applies in particular to hazardous waste such as impregnated wood, insulating glass units containing chloroparaffins and PCB and asbestos.

Uncertainties remain in the figuresOpen and readClose

The quality of the data used as a basis for the statistics is improving. There are still some uncertainties in the figures for demolition of buildings due to the quality of data for the area. The data for the square metres of rehabilitation is based on preliminary figures for 2012, and future changes might influence the waste figures.
