There's actually no need to compost wood and bark chips before use.
Just spread them in your paths. (It's what we do in Southwark/Queen
Village Garden.) Depending on how humid/rainy the year is, the lower
levels of the mulch will rot in a season or two...or over
winter...and can then be dug out as a really nice compost. (Just rake
off the top or dry layer and put it back after you've dug out the
compost.) Meanwhile, the chips do a fairly decent job of keeping
one's feet dry and one's weeds under control.
