tPB: Reusable Alternative Materials to Plastic: Clear as Glass, Tough as Cardboard
What is tPB? A study published in Science Advances reports[1] a brand-new material called transparent paperboard (tPB). Made entirely from pure cellulose, it solves the century-old problem of opaque paperboard and sets a new bar for sustainability: it can be fully recycled in a closed loop and biodegrades across the entire ocean—from shallow waters to the deep sea. Using a proprietary lithium bromide aqueous treatment, researchers have cured cellulose hydrogels into a range of practical shapes—from drinking straws to cups. Tests show that the tPB material matches plastic in everyd......
