Interwaste merged with two companies in 2015 that were registered with the Green Building Council of South Africa. To maintain their client base and demonstrate that the merger would not affect their Green Star Rating, Interwaste needed to register with the GBCSA and showcase how the merger would benefit clients with extended service offerings. Their exhibit at the 2016 GBCSA expo had a budget of R100,000 and aimed to promote this message to all attendees, including international guests and media.
