Paragraph starter
The production of Solid Recovered Fuels (SRF) from Mechanical-Biological Treatment (MBT) plants involves inherent trade-offs between maximizing output quality and managing reject material. Research indicates that achieving high purity in SRF is challenging due to the limitations of mechanical separation, and efforts to improve quality may increase the volume or problematic nature of waste streams. Therefore, a balanced approach is required, focusing on targeted improvements to meet specific market needs while acknowledging these fundamental compromises.
