Abstract

A method of recycling a contaminated article comprising: chopping and/or shredding the contaminated article; heating the shredded contaminated article to a temperature at a pressure to at least partially decontaminate the shredded contaminated article and/or to at least partially alter the physical form of the shredded contaminated article to provide a second article.The second article may be used in the manufacture of an end product such as a carrier bag.
