Capping production of new plastics will help cut their release to the environment — and brings other benefits, from boosting the value of plastics to helping tackle climate change.
“The amounts of plastics we have produced thus far have already exceeded planetary boundaries”
In a letter to the journal Science, an international group of scientists and experts now argue for tackling the issue right at the source, by regulating, capping, and in the long term phasing out the production of new plastics.
Recycling not enough
“Even if we recycled better and tried to manage the waste as much as we can, we would still release more than 17 million tons of plastic per year into nature,” says Melanie Bergmann of the German Alfred Wegener Institute, the initiator of the letter.
“If production just keeps growing and growing, we will be faced with a truly Sisyphean task,” she adds.
Research published in Science in 2020 shows that plastic emissions can only be cut by 79 per cent over the next 20 years if all solutions available today are implemented, including replacing some plastics with other materials, and improved recycling and waste management.
“The exponentially growing production is really the root cause of the problem, and the amounts of plastics we have produced thus far have already exceeded planetary boundaries,” says Bethanie Carney Almroth of the University of Gothenburg, Sweden. “If we don’t tackle that, all other measures will fail to achieve the goal of substantially reducing the release of plastic into the environment.”
Phasing out new plastics important
Phasing out the production of new plastics from fresh feedstocks should be part of a systemic solution to end plastic pollution, the experts from Canada, Germany, India, Norway, Sweden, Turkey, the UK and the U.S. argue.
“A comprehensive approach must also cover the supply side, meaning the actual amount of plastics produced and put on the market”
Along with measures to address the consumption and demand side of the problem — such as taxes — a comprehensive approach must also cover the supply side, meaning the actual amount of plastics produced and put on the market.
Reducing production increases value
Gradually cutting the production of new plastics will come with many societal, environmental and economic benefits, the scientists say.
Sedat Gündoğdu of Cukurova University, Turkey, says “the massive production also feeds the plastic waste transfer from the Global North to the South. A production cap will facilitate getting rid of non-essential applications and reduce plastic waste exports.”
“We gain a lot of benefits from plastics but reducing production will increase the value of plastics, boost other measures to curb plastic pollution, help tackle climate change and promote our transition to a circular and sustainable economy,” adds Martin Wagner, an ecotoxicologist at the Norwegian University of Science and Technology.
