The quantity of consumer and production waste generated in industry totalled 2.5 million tonnes last year, compared to three million in 1993. The composition of materials was almost the same in both years. Wood waste still accounts for the biggest share, with 32 per cent, compared to 30 per cent three years ago. Food, slaughtering and fish waste and paper and cardboard accounted for the same percentage both years, with 15 and seven per cent respectively. On the other hand, the percentage of iron and metal waste increased from six to 10 per cent.
2,9 million tonnes (metric tons) of waste were generated in Norwegian industry in 1996. This includes all types of waste, i.e. consumer waste, production waste and special waste. Overall, this represents a decline of 410,000 tonnes from 1993. On the other hand, the quantity of special waste increased from 320,000 to 400,000 tonnes during the same period.
More recycling
A considerably larger percentage of manufacturing and consumer waste is recycled or reused than previously. Forty-four per cent was delivered for recycling and/or reuse in 1996, compared to 27 per cent in 1993. In 1996, 19 per cent of the waste was incinerated to produce energy and 23 per cent of the waste was put in landfills. The comparative figures for 1993 were 30 and 28 per cent.
The group of materials with the highest recycling percentage in 1996 was iron and metals, with 93 per cent. Food, slaughtering and fish waste were also high, with 89 per cent. There were only small changes for both groups of materials from 1993.
There has clearly been a change in the handling of wood and plastic waste, where material recovery has climbed by 26 and 24 percentage points respectively. The 1996 recycling percentage for the reported quantity of glass was 75 per cent, while it was 69 per cent for paper.
