How much plastic has humanity produced in total?

Humanity had made about 8.3 billion tonnes of plastic by 2015, and production has run above 400 million tonnes a year since, so the total now exceeds 10 billion tonnes. Of all plastic waste ever generated, roughly 9% has been recycled, 12% incinerated and the rest landfilled or lost to the environment. Half of all plastic ever made was produced after 2004.
