Clean 2015 will be held over four days, rather than three, and take place from Thursday 16 April to Sunday 19 at the Georgia World Congress Centre in Atlanta.

The Clean Executive Committee (CEC) made the decision to revert to the four-day format after reviewing post-show surveys and feedback from exhibitors and visitors.

CEC chair Brian Wallace said the feedback on the three-day Clean 2013 had been very positive but it was clear that the best way to build upon that success was to add an extra day. He said that it would not only give visitors more time to explore the exhibits but it would also allow them to attend more educational sessions.

Clean 2015 will be the first time the event has been held in Atlanta since 1987 John Riddle describes the city as "a major destination with much to see and do."
