One of the most common sights on the coast - a tug pulling a chip barge between 2 scows of hog fuel. This is the Seaspan Navigator, on Malaspina Strait, almost at her destination of the Mill. Unfortunately the days when the Mill produced much of its own chips to turn into paper are long gone. And even at the best of times hog fuel was purchased on the open market to supplement that made in the now-gone Woodroom.
Hog fuel is a wood by-product - bark, sawdust, woodscraps - all are put through a "hog", a set of rotating hammers that pulverizes everything into fine particles, and this is used as fuel in the steam boilers to replace relatively expensive natural gas.
