Rejected hypotheses: analysing England’s recycling data

by Peter Jones and Andy Grant

 

Is the increase in recycling rejects in England due to an increase in the amount of contamination in recycling bins, caused by growing confusion amongst the public? Last month we identified a couple of other possibilities that would also explain the 184,000 tonne rise: better data capture, or better sorting at materials recycling facilities (MRFs). However, we didn’t attempt to assess which is the most plausible. In this article, we begin that tricky task.

Back to MRF: rejects and contamination

by Andy Grant and Peter Jones

 

When we wrote last month about the possible causes of the rise in reported recycling rejects, one of the concerns we raised was that materials recycling facilities (MRFs) have historically underreported rejects. We also highlighted the concerns reprocessors have in the past expressed regarding the quality of MRF outputs.

Can we sort out the contamination confusion?

by Peter Jones and Andy Grant

 

The latest flurry of disparagement around the 2014/15 stats on local authority recycling rejects provides an unfortunate reminder that this is a confusing topic. Indeed, it seems it is easy to misunderstand even if, like the Daily Mail and Daily Express, you’ve had it explained to you at length.

Material differences: collection methods, quality and export

MRF Material

by Andy Grant

 

Why is it that we export recyclate? The Daily Mail’s outrage regarding exports back in April may have been fuelled by the mistaken belief that much of the material is landfilled, but to some the fact that we ship recyclate overseas is quite outrageous enough: Doretta Cocks was reported as calling the practice “shameful”.
