Plastics Europe, the industry association for European plastics manufacturers, publishes an annual 'Fast Facts' summary of production volumes by region.
Its 2025 edition puts global plastics production at 430.9 million tonnes in 2024, up 4.1% on the previous year and 16.3% above 2018. Asia made 57.2% of the total (China alone 34.5%), North America 16.3% and Europe 12%. European output was 54.6 million tonnes, and 15.4% of EU plastics were classed as 'circular' (recycled or bio-based).
This is the most current production number available and the source for a 'plastic produced per second' counter: roughly 13.7 tonnes every second.
It is an industry source. The production volumes are widely used, but the 'circular plastics' framing should be treated with care.
