Define yourself as a Zero Waste Business Associate

Visit our upcoming events page for courses scheduled in 2016

Green Business Certification Inc. (GBCI) developed the Zero Waste Business Associate (ZWBA) certification system to train professionals to help businesses get to Zero Waste, and to help get their facilities certified as Zero Waste according to the GBCI Scorecard Certification System.

Certificate holders will gain a practical understanding of the most current Zero Waste business principles and practices, GBCI policies and processes, and demonstrate a clear commitment to professional growth in advancing Zero Waste.

GBCI Zero Waste Business Associates earn their credential by submitting an application, attending the 6-hour ZWBA Scorecard Training Course, paying applicable fees, and passing a computer-based assessment comprised of randomly delivered multiple-choice questions. Once certified, the role of a ZWBA is to implement Zero Waste programs, prepare businesses for the GBCI Zero Waste Facility Certification, and assist businesses through the certification process. Certified ZWBAs do not conduct certification audits, trainings, or any other business on behalf of GBCI.
