Transition from formaldehyde-based wood adhesives to bio-based alternatives

Bio-based wood adhesives are increasingly receiving greater attention than those of synthetic formaldehyde-based adhesives from petroleum sources in response to climate change. In this respect, this editorial provides an overview on the transition of formaldehyde-based adhesives to bio-based adhesives for the bonding of wood. This transition is underway in academia and industry for practical applications. Bio-based adhesives offer low toxicity, lower greenhouse gas emissions, and increased sustainability with circular economy by promoting renewable and degradable sources, which generates a driving force for the transition.
