Maybe? Even clean plastic degrades eventually (although I don't have a sense of how the timelines compare with modern carbon sequestration approaches), and much of the waste is probably things that decompose into methane and/or CO2 much faster. Meanwhile, you're not going to get much solar power at the times of year when Sweden probably most needs energy generation. The point is very well taken from other comments, though, that pollutants other than CO2 are probably also a significant concern even if CCS is, in isolation, up to the task.
