Launching plastic waste into space would be possible but far too costly. Estimates vary between £20,000 and £40,000 per kilogram for launching material into near-Earth orbit, and much more if we were to send it further away. This means that transporting the 300 million tonnes of plastic waste we produce globally each year into space would cost at least £6,000 trillion yearly. The same material could be recycled for a fraction of the cost.
Furthermore, there’s the ethical question of whether it is acceptable to dump our waste in near-Earth orbit. Article IX of the UN Outer Space Treaty obligates nations to avoid the harmful contamination of space, so any such endeavour would require some form of international agreement, which would be difficult to obtain.
