Conversion of Hemicellulose to Coatings

About HEMICOAT

Conversion of Hemicellulose to Coatings

The main focus of this project is the valorization of hemicellulose by-products from paper pulp manufacturing but also from other agricultural lignocellulosic biomass to obtain high value-added chemicals toward sustainable coatings, adhesives, and functionalized additives.

The two main objectives of the project are (i) to recover most of the hemicellulose oligomers from lignocellulose biomass processing and (ii) to use monomeric sugars and other residual compounds in fermentative conversion of the xylose fraction to produce itaconic acid as a building block for chemical synthesis of surfactants. Regarding the oligomers, the feasibility use in adhesives manufacture will be tested.

The Biorefinery concept

Fermentation/ Purification centrifugation filtration Itaconic Acid Chemical modification Surfactants Mixing with Chitin or Chitosan HC/Chitin/Chitosan Mix in water Evaporation Adhesives Pretreatment HC-containing Hydrolysate Purification/ Fractionation Lignocellulose C5 Sugar Hemicellulose Oligomers

Hemicellulose-containing hydrolysates from lignocellulose pretreatment are provided and the resulting products are tested by various companies in both User Committees.

Primary refining

  • Hemicellulose oligomers and C5 sugars are recovered and purified from hydrolysates.

Secondary refining

  • The concentrated and purified monomeric C5 sugars are fermented in a fed-batch process to itaconic acid. The product is purified for subsequent chemical modification to produce biobased surfactants, polymers, and building blocks.
  • The hemicellulosic oligomers are applied in formulations with chitin or chitosan as wood adhesives.

The User Committees

Since results obtained in the frame of the HEMICOAT project would be beneficial for a variety of small and medium enterprises (SMEs) which already using products or chemical reagents derived from itaconic acid by diversifying sources of supply, increasing quality or decreasing cost.

The results of the Hemicoat project will help small and medium enterprises (SMEs) that work with Itaconic acid-based products by diversifying sources of supply, increasing quality, or decreasing cost. Moreover, we see the possibility of technological breakthroughs for SMEs to replace their commonly used fossil-based reagents and materials with bio-based alternatives from itaconic acid, and extend the field of application towards anhydrides, coatings, plastics, or functionalized additives. We are convinced that the project will likewise impact SMEs interested in the valorization of their lignocellulosic and hemicellulosic agro-industrial wastes, and therefore open the perspective for new and sustainable business ideas. Hence many different companies (small- medium sized enterprises as well as large enterprises) have expressed their interest in the research and are therefore members of one of the two User Committees:
