To avoid wasting trees  木を無駄にしないために


Certain criteria exist for the logs that line the lumber market. Length, thickness, bend, species, etc., that may be sold for a high price are lined up. Then what happens to the rest of the trees, most of which are used as raw material for paper production, called chips. The chemicals of the trees I am focusing on has nothing to do with length, thickness, or bend.
