We are keeping quite a large pile of good hardwood logs for milling (we have a Timber King sawmill) or firewood (we have a 37-ton log splitter), as well as a separate pile of black walnut (a prize). Most of it is logistics. With our service area being 50 miles, fuel economy and stretching the crew across 2-3 trucks can make it economically unfeasible. That and if it's undesirable wood (Siberian elm or Ash), we would rather chip & dump ($10 or $20 per load, depending on where we dump, or free if we bring it home and put it in our Free Mulch pile). Dumping logs as the organic wood recycler is $90 a load, plus unloading time. Often we are rolling out 2-3 jobs per day, so we don't want to roll with logs from a large removal to another lighter pruning job in a small residential neighborhood.
