Polyurethane foams are so commonly used, from rigid dashboards in cars, to insulation in buildings, and the comfy mattresses we sleep upon. Replacing the petrochemical resources used to make them with renewable resources like bark would be a great stride towards sustainability. In order for this to be done the conversion process of bark into a liquid must be better understood. This project will try to elucidate how alcohols interact with the bark to digest it during the conversion process.
