Why regrind is worth tracking
Every kilo of regrind you reuse is a kilo of virgin compound you didn’t buy, so it’s real money. It’s also where quality problems start when too much goes back in, or the wrong grade or colour gets mixed. And when a customer complains, you need to know which runs fed the regrind in their batch.
This tracker handles all three. Each run is checked against its recipe’s maximum, so a run that went over is flagged the moment it’s entered, and the savings add up automatically so you can see what regrind is worth to you each month.
Tips for getting it right
- Keep grades separate. White rigid, grey rigid and flexible should never share a bag, and each needs its own grade code.
- Use a maximum of 0% for no-regrind specs. Some customers won’t accept any; the check will flag it if regrind slips in.
- Reconcile weekly. The difference between the stock the sheet expects and what’s actually there is your loss: sweepings, contamination and unrecorded use.

When the spreadsheet stops being enough
Mannin Systems does all of this as part of the day’s work: booked at the station as it happens, checked automatically, and linked to the jobs, stock and people involved. No retyping, and no Friday afternoon catching up.
