New Study Reveals PVC Waste Recycling's Potential to Significantly Reduce China's Carbon Footprint by 2050
A new modeling study indicates that recycling polyvinyl chloride (PVC) waste in China could substantially decrease the nation's environmental footprint by 2050. Researchers developed an integrated material flow analysis and life cycle assessment for all 31 mainland provinces, tracking PVC waste from five sources: construction, household, industrial, agricultural, and medical. The study projects China's PVC waste to increase from 11.51 million tonnes in 2020 to 20.59 million tonnes by 2050. Mechanical recycling is identified as having the lowest environmental footprint among treatment options, while chemical recycling becomes more competitive as China's power grid decarbonizes. Construction waste accounts for the largest portion of PVC waste at 51.70%, followed by household waste at 25.83%. The study highlights that improved recycling rates, particularly for construction and household PVC waste, could lead to a 77.53% reduction in mismanaged PVC waste and a 778.61% increase in regenerated resources by 2050....
