If you transport a thousand tonnes of plastic bottles from industries to ports by road, load them onto gigantic ships, take those ships 10,000 miles away from the UK to China, unload all the waste bottles, and move them to recycling centers, thats going to generate lots of carbon emissions. Nevertheless, a recent UK-based study shows rather than sending the waste to landfills in the UK!

mentions in the report that recycling is far better for the environment than landfilling, even if you ship waste from one end of the world to another. When used paper is taken from Britain to China for recycling, it saves around two-third emissions that would have otherwise resulted from landfilling. And when it comes to plastic bottles, savings are even greater.
In addition to all this, since most ships go empty from the UK back to China because of the imbalance of trade, they would release CO2 whether you export waste or not. WRAP estimates that every tonne of waste recycled this way results in emissions reductions of around 1300-1600 kg of CO2.
