LCA gives recycled LDPE a clear edge

Producing carrier bags from recycled polyethylene gives massive reductions in energy and water consumption and releases to the environment when compared to production from virgin material, according to a life-cycle analysis (LCA) carried out for the leading recycling business Alida.

The results were obtained in a study carried out by a University of Nottingham team.

The study was based on a comparison of measured resource consumption and releases to atmosphere from Alida's collection, transport and recycling operation with literature data for virgin low density polyethylene (LDPE) production.

The results are summarised in the table . They show that, on all five parameters, recycled LDPE carrier bags offer hand
