Getting rid of fossil fuels and avoiding the accumulation of plastics in the environment is key to addressing the challenges of climate change, and to address such issues, the development of "lignocellulosic biomass", a degradable or recyclable polymer made from inedible plant material, has become A major aspect of future effor.
Of course, producing competitive biomass-based plastics is no easy ta.
Scientists led by Professor Jeremy Luterbacher from the School of Basic Sciences at EPFL have succeeded in developing a biomass-derived plastic similar to PET that meets the criteria to replace several existing plastics and is also more environmentally friend.
"We're basically just 'cooking' wood or other inedible plant material like agricultural waste with cheap chemicals to produce plastic precursors step by step," Luterbach sa.

By using a different aldehyde - glyoxylic acid instead of formaldehyde - we can simply sandwich the 'sticky' groups on either side of the sugar molecule and then make them act as plastic building bloc.
The comprehensive properties of these plastics allow them to be used in a variety of applications, from packaging and textiles to pharmaceuticals and electroni.
"This plastic has very exciting properties, especially in applications like food packaging," Luterbacher sa.
The research was published in Nature Chemist.
