Evaluation of lignin-based amendments for hydrocarbon remediation applications

Leaky fuel tanks and spills from fuel storage and retail locations have resulted in over 30,000 hydrocarbon contaminated brownfield sites across Canada. The objective of this project is to develop an injectable solution that will encourage local bacteria in the subsurface to degrade oil, diesel, and gasoline hydrocarbons on brownfield sites. Lignin, a by-product from the pulp and paper industry, will be modified to form a material that can both adsorb fuel hydrocarbons and attract hydrocarbon-degrading bacteria. Experiments will be conducted at the bench scale to evaluate the material and to ensure the biodegradation process is environmentally safe. In addition to helping cleanup the environment, the results from this project may help to expand the lignin market for West Fraser and drive job creation in Canada.
