Plastics not only harm the environment when they're thrown away, they also produce greenhouse gases during manufacturing. But it is possible to make plastic from wood, reducing the need for fossil fuels and reducing the impact on global warming. This video is funded by Dow.

CORRECTION: When the cellulose is being extracted from the wood to make paper, both the lignin and the pitch are left behind. But it's the pitch (not the lignin) that goes into the crude tall oil. Sorry I got this wrong in the video (and I wish the YouTube annotations feature was still a thing).
