Glass recycling prospects and limitations

Abstract

Since 1974 the glass recycling in Germany, Switzerland and the Netherlands has grown from less than 10% to almost 50% of the one-way produced glass. With the increased tonnage of collected glass the demands on the quality of the produced glass cullet by the glass recycling industry have changed. These quality changes in the cullet feed of the glass production process were necessary to guarantee the same high quality product of bottles of the glassworks as before.
