This year's 19th edition of the Paper & Plastics Recycling Conference North America, held in Chicago from October 17 through 19th and produced by the Recycling Today Media Group, was a very informative, well organized and well attended event, and a good reflection of the mixed feelings currently being expressed by the industry with respect to the state of paper and plastics recycling. On the technology side of the industry, things are largely positive. Business is good. From the latest plastics additive and stabilizing technologies designed to enhance the physical properties and thereby the quality of recycled plastics for compounders and other reprocessors, to the significant advances in sorting, screening and other equipment being put forward by leading manufacturers, it is clear that there is solid demand, and excellent solutions available to help profitably create better quality recycled materials from challenging input streams. The advances in this sector are in fact rapid and ongoing. The latest robotic and optical sorting, coupled with artificially intelligent (AI) "learning" technologies, are particularly impressive - making it difficult for anyone to deny that high-tech materials sorting has a huge role to play in the future of this industry.
