All glass collected in Sweden is transported to the Svensk Glasåtervinning works in Hammar in southern Närke, the only reprocessing plant for recycled glass in the country. Demographically, Närke is in the middle of Sweden, i.e. as many people live north of it as live south.
All collected glass goes through a number of manual and mechanical controls to grade out pollutants and foreign matter. Recycled glass must have a high degree of purity if it is to be successfully turned into new glass raw material. The glass is crushed into different orders of magnitude depending on what it is to be used for.
