Imagine if you can a slab fire which has been kept alive day and night almost continuously over a period of 55 years by the refuse from a single large sawmill. Try to realize that this is an actual mill operating in the redwood region of California and that it is only one of many mills of similar size. You can not then help wondering why so much potentially valuable material must be wasted.
