My crew rolls their eyes when I stash old cable, but I stand by it
In my experience, a lot of guys on the job think tossing every bit of removed wiring is the only way to go. They say it speeds things up and avoids clutter. But I always set aside good sections of coaxial or Ethernet from tear-outs in a marked bin. Last Tuesday, I fixed a customer's intermittent signal by using a salvaged ten-foot piece instead of cutting into a new spool. That saved money and kept more plastic out of the dump. Sure, it adds a minute or two to clean and coil the cable, but over a month, I've reused enough to fill a couple of trash bags. Your mileage may vary, but I feel we should try to reduce waste where we can. A little habit like this can help the environment without hurting our efficiency.
