Rapeseed pomace bound fibreboard (bulk density 800 kg/m³).


Abstract

To produce wood-based composites urea-formaldehyde resin is the most widely used binder. However, UF resins are susceptible to hydrolysis and wood-based materials will thus emit formaldehyde. Scientists at the University of Göttingen, Germany developed an alternative formaldehyde-free binder based on oil plant residues (pomace).


Background

By far the most commonly used binders for the production of wood-based composites are the so-called urea-formaldehyde (UF) resins. However, these are susceptible to hydrolysis and therefore the produced wood-based materials still emit formaldehyde even years after their production. Scientists at the University of Göttingen, Germany developed a biological binder based on oil plant residues for the production of composite materials. The new formaldehyde-free binder has excellent properties and could therefore replace existing binders in many applications.

Problem

Currently, mostly petroleum-based polycondensation urea-formaldehyde (UF) resins are used for the production of wood-based materials. With all the technological  advantages of these resins, however, a decisive disadvantage remains, namely that these resins are basically susceptible to hydrolysis and therefore the wood-based materials produced still emit formaldehyde even years after their production. It is therefore necessary to provide alternative binders, in particular binders that are formaldehyde-free so that no or only insignificantly formaldehyde will be emitted after production of wood and composite materials.


Solution

Scientists at the University of Göttingen, Germany developed a biological binder based on oil plant residues for the production of composite materials. In addition, the invention also refers to a process for the preparation of binders containing further processed pomace of oil plants. The new formaldehyde-free binder has excellent properties and could therefore replace existing binders in many applications.


Advantages

  • Bio-based binder for production of wood and composite materials.
  • Products are formaldehyde-free or emit only insignificantly formaldehyde after production.
  • Simple and fast manufacturing process of binder containing processed pomace of oil plants.
  • Sustainable production due to use of waste products (byproducts) from plant oil production.

 


Scope of application

Production of of wood and composite materials using new bio-based binders that are formaldehyde-free or emit no or only insignificantly formaldehyde after production.
