What are good garden/outdoor uses for resin coated MDF boards?

I've acquired a large stack of MDF boards from deconstructing old cabinets and what not and I'm looking for some uses for it. I'm not sure what the resins/laminates are made of; I'm thinking it's no good for direct contact with soil where I plan to grow edibles, but I don't know. Besides building shelves, do you have any clever ideas or uses? Or is there an easy way to remove the laminate to use the underlying wood?

The binders in the MDF aren't a lot better than the laminate adhesives. I have tried to use them in non-food areas and they die REALLY fast in the rain. And who knows what just soaked into the ground.
Personally, I'd use them for shelving or countertop in a potting shed, garage or barn, where they don't get rained on or leech unknown chemicals into the soil. Looking around, there's one in my grow light area holding a pot up at the right height.

That's just my two cents :)
Perhaps someone else will have better ideas
