Glass Remelt Savings Calculator
Glass Remelt Savings helps glass plants value internal cullet loops, cutting scrap recovery, and rejected glass remelt. It combines remelt tons, avoided cost, allocation, and fixed handling cost.
What this calculator does
- Estimate net savings from returning scrap glass or cullet to remelt instead of buying virgin batch or disposing waste.
- a glass plant needs to quantify savings from remelting cullet or internal scrap
- The result estimates net savings assigned to the remelt stream.
Formula used
- Allocated glass remelt savings = cullet or scrap glass returned to remelt × avoided virgin batch or disposal cost per ton × allocation share
- Glass Remelt Savings = allocated cost + fixed cost
Inputs explained
- Cullet or scrap glass returned to remelt: Use cullet or scrap glass returned to remelt from the same material, product, equipment, batch, shift, or order scope.
- Avoided virgin batch or disposal cost per ton: Use avoided virgin batch or disposal cost per ton from the same material, product, equipment, batch, shift, or order scope.
- Savings assigned to this furnace, line, or product: Use savings assigned to this furnace, line, or product from the same material, product, equipment, batch, shift, or order scope.
- Fixed sorting, crushing, or handling cost: Use fixed sorting, crushing, or handling cost from the same material, product, equipment, batch, shift, or order scope.
How to use the result
- Use it for cullet projects, cutting-room recovery, defect loops, and furnace batch cost reviews.
- Savings depend on cullet quality, color compatibility, contamination, crushing cost, and actual virgin-material offset.
Common questions
- What is Glass Remelt Savings for? Estimate net savings from returning scrap glass or cullet to remelt instead of buying virgin batch or disposing waste.
- What information do I need before using it? Enter remelt tons, avoided cost per ton, allocation share, and fixed sorting or handling cost.
- When is the result only an estimate? Savings depend on cullet quality, color compatibility, contamination, crushing cost, and actual virgin-material offset.
- How can I use the result? Use the result to justify cullet handling, improve scrap segregation, or update batch cost assumptions.
