Bollegraaf now has dozens of Single Stream Systems in operation. The first ones were operating in Los Angeles at 20 tons/hr with 20 people (1998). The system produces perfect # 8 news automatically with the Lubo Starscreen for news. After this screen mixed fiber is automatically separated from bottles & cans by the Lubo Single Stream separator screen (or angled sorter). Hand sorting is still needed for the plastics and the glass by color. There are different systems for different capacities available. Key in the Bollegraaf Single Stream System is the speed of processing, quality of end products and low labor requirements.
