A new report by the Organisation for Economic Co-operation and Development report found that 460 million tonnes of plastics were used last year, the number nearly doubling since 2000.
The amount of plastic waste had more than doubled during that time to 353 million tonnes, the Paris-based OECD said.
“After taking into account losses during recycling, only 9% of plastic waste was ultimately recycled, while 19% was incinerated and almost 50% went to sanitary landfills,” it said in its Global Plastics Outlook.
“The remaining 22% was disposed of in uncontrolled dumpsites, burned in open pits or leaked into the environment.”
The Covid-19 pandemic saw the use of plastics drop by 2.2% in 2020 compared to the previous year. However, single-use plastics rose and overall use is “projected to pick up again” as the economy rebounds.
Plastics contributed 3.4% of global greenhouse emissions in 2019, 90% of it from “production and conversion from fossil fuels”, the report said.
In the face of rampant global warming and pollution, “it will also be crucial that countries respond to the challenge with coordinated and global solutions”, OECD Secretary-General Mathias Cormann said in the report.
The OECD proposed a series of “levers” to address the issue, including developing the market for recycled plastics, which only represent 6% of the total – largely because they are more expensive.
It added that new technologies related to decreasing the environmental footprint of plastics was only 1.2% of all innovation concerning the product.
While calling for “a more circular plastics lifecycle”, the OECD said that policies must also restrain overall consumption.
It also called for “major investments in basic waste management infrastructure”, including 25 billion euros a year to go towards efforts in low and middle-income countries.
The reports come less than a week before the UN Environment Assembly begins on Feb 28 in Nairobi, where formal talks are expected to begin on a future plastics treaty, the scope of which is still unclear.
According to a survey published Tuesday by polling firm Ipsos for the World Wildlife Fund carried out in 28 countries, an average of 88 % of respondents said an international treaty to combat plastic pollution was “fairly important (23%), “very important” (31%) or “essential (34%).
