Verification
| Test | - Pick three jobs that allow regrind (plastic ground up and molded again).
- Put an empty bin at each press for one shift, for leftover plastic and rejected parts only.
- At the end of the shift, weigh each bin on the floor scale, less the empty bin.
- Write down the job, the plastic and the pounds.
|
| Cost | Under $100 of a material handler's time: 90 minutes over one shift, at $30 an hour. Nothing is bought. |
| Duration | One shift |
| Confirmed if | The three bins together weigh about 25 pounds or more. Over a year of shifts, that is the 6,250 pounds per grinder the figure assumes. |
| Ruled out if | - The three bins together weigh less than about 4 pounds.
- Then a grinder would not cover what it costs to run.
- In between, a grinder pays back more slowly than the figure assumes.
