Turning Wood Into Plastic

University:  Yale School of the Environment

Objective of study: Development of high-quality bioplastic from wood byproducts and can be recycled or biodegraded.

Process and applications:

  • Biomass-based plastics from wood, but also plastic that delivers good mechanical properties as well
  • Process of deconstructing the porous matrix of natural wood into a slurry
  • To create the slurry mixture, the researchers used a wood powder — a processing residue usually discarded as waste in lumber mills — and deconstructed the loose, porous structure of the powder with a biodegradable and recyclable deep eutectic solvent (DES)
  • The material shows high mechanical strength, stability when holding liquids, and UV-light resistance
  • It can also be recycled or safely biodegraded in the natural environment, and has a lower life-cycle environmental impact

Benefits

  • The Bioplastics can be molded into a film that can be used in plastic bags and packaging. The bioplastic can be molded into different shapes, it has potential for use in automobile manufacturing, as well.
