Burning treated lumber

[Brian Kloepfer]

Would you or would you not burn old dry treated lumber in your arch to make maple syrup. I now the lumber puts off a poisonous gas when being burnt.

NO. To many nasty's in the fumes and smoke and ash.

Never burn it all (not even on the brush pile), it gets sent to the landfill.

[Russell Lampron]

I agree, don't burn it ever, especially not in your evaporator.

[wnybassman]

Made it a point since the beginning never to burn it.

[motowbrowne]

I wouldn't burn it in the cooker or anywhere else.

As others have said, don't ever burn it ever. Especially the older stuff (pre-early 2000's), as it most of it from that time period contains chromated copper arsenate. Super super nasty stuff.

Stick to firewood, for sure.

Not only that, but I've seen pans riddled with tiny pinholes caused by burning various things (treated lumber, maple tubing, etc.) in the arch. Apparently it left small deposits of various chemicals on the bottom of the pans, which then combined with moisture in the air over the summer to create some really nasty acids which ate right through the metal.
