Evaluation of life cycle inventory data for recycling systems.

Highlights: [•] Paper reviews data on material recycling used in LCAs of waste management systems. [•] In total 366 datasets, from 1980 to 2010, covering 14 materials, were evaluated. [•] Totals for emissions of CO₂-equivalent were compared to illustrate variations. [•] The choice of dataset is crucial for the outcome of an LCA on waste management. [•] Recycling in general showed lower emission of CO₂/kg material than primary production. [ABSTRACT FROM AUTHOR]
