Project context

Bioremediation of creosote-treated wood by fungal fermentation – Identify fungal strains capable of growing on creosote-treated wood (class 4)

In France, 6 million tonnes of wood waste are generated every year, of which 1.4 million tonnes are treated with chemical agents presenting environmental risks. This waste is simply incinerated, as recycling or recovery is impossible due to the toxicity of the compounds used to preserve wood.

Among these substances, creosote is one of the most toxic and persistent. It is mainly used to treat wood for railway, electrical and telecommunications infrastructures.

Every year, around 100,000 tonnes of creosote-contaminated wood are produced.

Goals

Feasibility study of an innovative creosote wood treatment method based on fungal diversity.

Evaluation of 30 fungal strains for their ability to grow and degrade creosote on two types of wood (hardwood and softwood).

Outcomes – Expected Impacts

  • 30 fungal strains will be evaluated for their ability to grow and degrade creosote on 2 wood models (1 hardwood and 1 softwood) from representative samples of industrial waste.
  • New technology for treating creosote-treated wood
  • The strains identified could also be used for the bioremediation of effluents from wood preservation treatments.
  • At the same time, we are exploring possible uses for depolluted wood residues.

Target markets

  • Wood recycling
  • Materials: panels, composites
  • Energy: shreds, pellets
