Goldilocks

Several hundred million years ago, Mother Nature invented lignin to allow aquatic flora to flourish on land. Lignin is a natural UV blocker, antioxidant, antimicrobial agent, resin, energy carrier and much more. Global annual production of lignin by photosynthesis is over 20 billion metric tons vs. 4-5 billion for fossil oil. The paper sector, along with cellulosic ethanol plants, produce over 100 million tons of lignin annually as a by-product, which is burnt onsite for energy.
