With funding and mentorship support from the Reef Resilience Network, artist Paco Lopez-Mujica of Arrecifes Pro Ciudad—a community-based organization that manages the Isla Verde Marine Reserve in Puerto Rico—developed a cooking oil recycling program to protect the health of Isla Verde’s coral reefs. Over time, cooking oil from condominiums builds up and blocks pipes carrying wastewater, resulting in sewage overflows in the streets and on the beach. Sewage carries harmful levels of nutrients and sediment into coastal waters that can harm coral reefs and fish communities. To encourage residents to take action to keep cooking oil out of their pipes, Paco designed a graphic manual with artistic illustrations that inform residents on proper cooking oil disposal. He also held meetings at eight condominiums located near the Isla Verde Marine Reserve.  All eight condominiums voluntarily adopted and implemented the cooking oil recycling program, and the program has since expanded throughout Isla Verde. In addition, Paco is working with the municipalities of San Juan and Carolina and expects the recycling program to be adopted throughout both regions in the near future. Paco next hopes to determine the long-term impact of the cooking oil recycling program. To help him achieve this, the Environment Protection Agency has provided Arrecifes Pro Ciudad with monitoring equipment to collect water quality data in the Marine Reserve.
