It would be for an enterprise doing that on an industrial scale. Then it would be worth the capital investment. Looks like it turns out very good briquettes. Briquettes the size and weight of which could be stacked manually. I've seen the briquettes turned out by a local scrapyard here and they are shambolic, with the compaction being shambolic, bits and pieces falling off and always close to actually falling apart. But, true, not worth it for the backyard enthusiast.
