Targeting the issue of global plastic waste leakage, the Yunus Environment Hub has developed a modular social business approach. Through the development of local social businesses, municipal waste management systems in developing countries highly affected by plastic waste leakage are strengthened. In collaboration with the Alliance to End Plastic Waste, the first two Zero Plastic Waste Cities have successfully been piloted in India and Vietnam. Two more Zero Plastic Waste Cities are currently being developed in East Africa. Run by teams of local entrepreneurs and staff, all social businesses founded during the course of the Zero Plastic Waste Cities program increase the amount of locally collected and recycled plastic waste while providing income opportunities to informal waste pickers and improving local livelihoods.
