Nope. However, I'd avoid the shiny stuff as I've heard the ink isn't eco friendly. We just got a new (small) paper shredder, and my wife has been using the stuff for the baby chicks crate. It'll decompose.
I worked at a humane society a long time ago. We tossed anything in the newspaper with color ink, only kept the black and white pages. It was something about the chemicals in the ink. Of course this is mulch, not animal bedding....No idea if the ink chemicals would affect veggies if you used it to grow.
I don't see a problem at all since paper is a wood product and most ink any more is a eco friendly soy based product. Be careful of the shiny adds in the news though. They is to slick to blow yer nose in or wipe yer azz without making a big greezy mess.
Itll all decompose. Some is just more eco friendly than others. If we are talking organic, nope...skip the paper. If we are talking green cycling, compost away. The B&W paper is easier to make disappear. Side note...have you ever tested the burn rates of colored vs B&W newsprint? If not, try it. You'll see why.
Kind of similar to the burn rate of a 4 month old Christmas tree! I regularly use cardboard boxes to start fires in the outdoor fireplace. Works great. Too much shredded paper to get rid of via the controlled burn techniques. No restarts after November 1 in the wood stove, so no need for it there.
Shiny printed pages- the shine , aka slick surface , is a clay coating that crushed into the fibers of the page, also the reason doesn't like to burn to well.
