Amount of waste materials and recycled products
Within the mining sector there are thousands of millions of tons of by-products (tailings etc.) which are stockpiled and possible for use as aggregates in the construction industry. Many millions of tons are produced every year. The main problem is that they exist on remote locations.
From the metallurgical sector approximately 1.5 million tons per year is produced in the form of slag, approximately equally divided between iron slag and steel slag.
The amount of constructions waste is approximately 10 million tons per year (including excavation etc.) of which a big portion is used as for e.g. road bases and landfill. The amount of concrete being deposited is approximately 0.25 millions tons per year. The construction industry target is, reducing the construction industry waste by 50% in the year 2000.
The major part of concrete waste is used for subbases, road banks etc. Approximately 200,000 tons per year is recycled. Most of the recycling is likely to be done by small companies having mobile crushers but interest from big aggregate producers is increasing.
From the area of recycled consumer products could be mentioned that there is a yearly amount of 40,000 tons of waste glass.
