Serious question, is the exhaust from the solid rocket boosters "environmentally friendly"?

"Serious question, is the exhaust from the solid rocket boosters "environmentally friendly"? "

I'm no expert, but here's my guess... the Solid Rocket Boosters are just as the name indicates. A solid chemical compound that is burned. That would most likely NOT be environmentally friendly.

The main tank, the big orange thing, is filled with liquid, mostly oxygen. That would be environmentally friendly.

So, the answer could be, yes and no.

LOX (Liquid Oxygen) + LH (Liquid Hydrogen) = Explosion + water.

Hell no!
Its main constituent is the dreaded Hydrogen Dioxide!

no - it is horrendously toxic.

so, yes: the ecofriendliness of the new foam amounts to less than a drop in the bucket per launch.
