speaking of heat and pressure, engineers at the University of Maryland have found that removing lignin from wood and then compressing it at 65°C causes the cellulose fibres to become very tightly packed, making it twelve times stronger than natural wood and ten times tougher. Would that also be called "plastic"? (https://www.umdrightnow.umd.edu/news/umd-researchers-create-super-wood-stronger-most-metals)
