That 10% is going to be country specific, much higher plastic recycle rates are possible and are already happening in some countries.

In the eu about 40% of plastic packaging waste gets recycled, but with significant differences per country: https://www.europarl.europa.eu/topics/en/article/20181212STO21610/plastic-waste-and-recycling-in-the-eu-facts-and-figures

Slovakia and Belgium are/were the eu's best performers in 2022. When looking for more general figures for Belgium, instead of only packaging, I found that 38.6% of plastic waste was recycled and 59.8% was used for energy generation, while the rest ended up in a landfill. https://plasticseurope.org/wp-content/uploads/2024/05/CircularEconomy_nationalinfographics_2024.pdf
