The framing here is a bit binary - it's not that recycling is either totally fine or pointless, it's messier than that. Yes, some exported plastic does end up mismanaged abroad, but the real question is whether your local council actually sends material for export or processes it domestically, and that varies hugely by region. I looked into what happens with my own recycling bin after a few stories like this circulated, and it turned out my local authority has contracts with UK processing facilities for most of it - some plastic still gets exported, but to licensed operations, not dumpsites. The honest answer is you can't know for certain what happens to yours without checking your council's waste reports or contacting them directly. That said, the best thing you can do isn't to stop recycling; it's to reduce plastic consumption in the first place, since less waste leaving your house means less that can go wrong downstream.
