I think you might be referring to the pine bark nuggets, but I haven't checked out the mulch situation at Home Depot this year yet, so they may have some recycled mulches I don't know about. The nuggets break down more slowly than shredded bark, but some of them often end up in the lawn after a heavy storm. They don't work well on paths because they don't pack down enough to form a nice walking surface, but they are good around shrubs and trees.
