Wood is renewable when you can grow it, cut it up into useful shapes, then at the end of its useful life, compost it. As soon as you add a shit load of processing and plastic and other stuff it's not "wood" anymore than gasoline is a dead dinosaur. As for things like plywood that use glue for the laminations...glue is the most expensive and important part of the product. Not the wood so much. Replacing steel? I don't think so. Yes, steel is a dirty thing ecologically... but steel things last a long time... and require, in general minimal processing...unlike this hardened wood proposal. If steel showed up today as a new material, it would be lauded for all its technical properties. But it is now old and not so sexy.
