Circularity Study on PET Bottle-To-Bottle Recycling

With the European Green Deal, importance of recycled products and materials has increased. Specifically, for PET bottles, a high content material (rPET) is demanded by industry consumers. This study was carried out in lab environment replicating real-life industrial processes, to investigate possible impacts on rPET quality over eleven recycling loops, aiming use amounts repetitively. A cycle included extrusion, solid state polycondensation (SSP), second extrusion simulate bottle production, hot wash drying step. 75% 25% virgin were extruded cycles production process. Samples underwent chemical, physical biological analysis. The not adversely affected. Parameters such as coloring, intrinsic viscosity, concentration critical chemicals presence mutagenic contaminants could be positively assessed. produced likely influenced input material’s standard. closed loop process using an up when following proposed process, indicating that this level can maintained indefinitely without compromising quality.
