New research by The Pew Charitable Trusts and SYSTEMIQ has found that the plastic flow into the oceans could triple by 2040 without immediate action. But the study, “Breaking the Plastic Wave: A Comprehensive Assessment of Pathways Towards Stopping Ocean Plastic Pollution,” also outlines solutions that could cut this plastic waste by more than 80%. According to the researchers, the methods currently used to deal with plastic pollution are less effective unless they are consolidated and accompanied by new technology and more research.
The report shows that if governments continue addressing plastic waste as they are currently, the amount of plastic waste flowing into oceans could only be reduced by 7% in the next 20 years. With no intervention, the plastic waste entering the ocean could grow from 11 million to 29 million metric tons by 2040. Because plastic lasts for hundreds of years, the cumulative amount pf ocean plastic could reach 600 million tons (the equivalent weight of 3 million blue whales) by that point.

“Breaking the Plastic Wave” identifies eight measures that could reduce plastic waste by 80%. The proposed measures include reducing plastic production and consumption, substituting plastics with biodegradable alternatives, designing product packaging for recycling, increasing recycling, increasing waste collection rates and reducing plastic waste exports. More technological advancements, business models and research and development are needed to completely eliminate plastic waste in the oceans, according to the study.
Although many of these methods are already being applied by some governments, the report proposes a more consolidated approach. The researchers estimate that governments could save up to $70 billion and reduce plastic-related greenhouse gas emissions by 25% by 2040 by adopting these measures together.
According to Martin Stuchtey, SYSTEMIQ’s founder, the plastic pollution problem is solvable if action is taken now. “Our results indicate that the plastic crisis is solvable,” Stuchtey said. “It took a generation to create this challenge; this report shows we can solve it in one generation.”
