Having done a lot of DIY projects over the last decade, I've really shifted my view of OSB. Originally I would lump it in with particleboard, but I've since drastically changed my view of it. Particleboard is, truly, junk. OSB and plywood are both pretty good products, and for some uses superior to hardwoods (dimensional stability, for example). High quality plywoods are amazing products. OSB for structure or underlayments are really quite good.

Unless there is a drop of moisture, then you throw it all away.
It’s so depressingly wasteful.
I'm using it for my next workbench top.
Unless there is a drop of moisture, then you throw it all away.
I went with IKEA's Sektion cabinets to replace some forty year old particleboard cabinets that warped after years of water damage from a burst pipe. They came with a twenty-five year warranty so there's clearly some expectation of longevity.
But as with all things, I'm certain some producers are using raw/virgin materials. Probably from wood that is dirt cheap.
The amount of sawdust needed to create a sheet of this stuff is astronomical compared to the output, not to mention the manufacturing process being very resource intensive. You also cannot just take bags of sawdust from the wood mill - it must be macerated and ground to a very fine dust with roughly the consistency of flour.
The main advantage it has is that it is heavy (to weigh down furniture) and very easy to cut with bandsaws, mills, lasers, etc because of its uniform distribution of its constituent parts. It’s also good for applying vinyl wraps and edging which is one reason why arcade cabinets are often made from it.
All this for a product that is roughly the same price as A cabinet-grade ply:
MDF 3/4” x 4’ x 8’ for $52.98: https://www.homedepot.com/p/3-4-in-x-4-ft-x-8-ft-MDF-Panel-D...
Radiata Pine plywood 23/32” x 4’ x 8’ for $55.98: https://www.homedepot.com/p/23-32-in-x-4-ft-x-8-ft-Cabinet-G...
If I'm building something I try really hard to avoid it, I can only assume the dust is really toxic to breath in and I don't have money or space for a fancy dust collection system.
Baltic birch would be stronger, no doubt, but that's 3 times the price and I am not exactly storing a geode collection up there.
