I want to say one word to you. Just one word. Are you listening?

Lignin.

Just how do you mean that, sir?

Meant as a thesis topic, for a graduate.

Back before there was plastic (1930s), in the days when they started manufacturing cars (1890s), Henry Ford used hemp resin-soaked and oriented-strand pressed board for durable contoured door layers and dashboards.

There have been promises and some use of wood for chemicals and plastics in the past. But using wood for houses and paper are still the major use for our continuously renewable forests (vs. finite oil). Using the lignin is ingenious. I sure hope this takes off. I'll be harvesting my once-in-a-lifetime crop of timber in 10 years or more when I'm 80+.

Since lignin is about half of the volume of a tree, you can imagine there is a lot of it around. Mostly it is concentrated and burned as a fuel to provide steam for papermaking,reducing demand for alternative fuel to dry paper. But there is another pulping process where the lignin is a waste product so there should be lots of it available.
Wood chemists have been intrigued with lignin for years and years.

Great movie.
