Beyond Plastics: Problem and Solutions in Puerto Rico

Environmental justice and the changes needed to achieve it start from our communities. Therefore, we invite you to a training that covers the current state of the plastic waste crisis on the Island, what you need to know to act, the measures that have been taken from the point of view of public policy, and the platform created by already-established actors. This workshop has been organized as a result of the collaboration between Beyond Plastics, Syracuse University Center for Sustainable Materials, CAMBIO, Generación Circular and Estuario. Two dates available, Friday, May 13 and Saturday, May 14, 2022, from 10AM-12PM.  Both dates will feature the same workshop.
