Single stream recycling is a single-sort recycling collection system. Many collection agencies in the UK and all across the United States are using this system to simplify their recycling bin collection process. Residents can place a mixture of recyclable goods into their recycling bins instead of having to separate them as in the past. All items collected will then be sorted at a Materials Recovery Facility (MRF) for reuse. Councils across the UK are hoping that single stream recycling will encourage residents to recycle more goods.
