We are pleased to introduce invited papers selected from authors who presented at the 8th International Conference for Conveying and Handling of Particulate Solids (CHoPS2015) held in Tel Aviv, Israel, during 3rd to 7th May 2015. All papers have been rigorously and independently peer reviewed and we extend our thanks to the authors for submitting work of such high quality. Over the past 20 years, CHoPS events have become leading conferences on the handling and processing of bulk solids. CHoPS2015 was, as the organizers promised, “a great scientific event but also a most pleasant and memorable experience” as will be the next CHoPS conference to be held in London, UK, on 10th to 14th September 2018.
