The Interwaste golf day was held in September 2014 to celebrate the company's 25 years in waste management. Over 360 personnel from Interwaste, its customers, suppliers, and shareholders participated in the event across two golf courses. Various suppliers sponsored each hole and prizes. Planning for the event took 3 months and involved coordinating sponsorships, the golf courses, and other logistics through a team of 30 people. The total cost was R750,000 with Interwaste contributing R300,000.
