[p2tech] Creosote replacement

Robert,
 
Another option might be to make ties out of alternative materials that do not require preservatives. There are commercially viable alternatives that utilize recycled plastics, recycled tires and wood/plastic mixtures. Moving forward, the viability of creosote or other chemical preservative use as a "necessity" may be very limited.

I am working with a manufacturer of railroad ties. They currently use creosote distilled from coal tar in a pressure treatment system. Are there any environmentally friendly replacements for creosote? Can anyone point me towards some studies showing replacements that work as well as creosote? I have spent a few days searching and have not found anything note worthy. I did notice a discussion on CR4 about cedar oil, but there were not any valid references provided.
Thank you,
