Sweden is the best country in the world at recycling glass. An important part of this work takes place at Svensk Glasåtervinning (Swedish Glass Recycling), which recycles glass containers from all across Sweden. Their processing plant is the only one of its kind, yet the company is upgrading its entire control system in order to optimize productivity and improve the quality of the glass it sells to its customers. FVB has been enlisted to upgrade the system and the plan is for it to be up and running by the autumn.
The processing plant is located in Hammar, on the northern tip of Lake Vättern and operates 24 hours a day, five days a week. Approximately 25 lorries laden with waste glass arrive every day. The glass is sorted by colour (green, brown and clear) and washed and about one third of it is pulverized. But several important steps are involved in order to produce the product that the customers require, because it is not just waste glass that ends up in the recycling bins up and down the country. – We find stones, ceramics, organic material, and metals etc., things that need to be removed. The first screening is done by hand, says Ulf Hellström, Head of Technology, Environment and Quality at Svensk Glasåtervinning.
