Timber Waste Recovery Calculator: Reusable vs Scrap Wood
Sort measured timber offcuts into potentially reusable and scrap groups using minimum length, width and thickness thresholds. The tool reports both volume recovery and piece-level classification.

How timber waste recovery is classified
A piece is considered potentially reusable only when its length, width and thickness all meet or exceed the thresholds entered by the user.
Reusable volume = reusable-piece volume × reusable count
Recovery rate = reusable volume ÷ total volume × 100
Why classify by dimensions?
A pile of offcuts often contains material that can be reused for blocking, short components, battens, templates or repair pieces. A simple percentage waste figure cannot show how much of that pile remains practically useful.
Thresholds are application-specific
A 300 mm offcut may be valuable for one job and unusable for another. Define the threshold based on the actual reuse plan rather than a generic waste rule.
Volume recovery is not economic recovery
Even a high geometric recovery rate does not guarantee financial value. Sorting, storage, handling, machining and labor can make some recovered pieces uneconomic to use.
Frequently Asked Questions
Does a piece need to meet every threshold?
Yes.
Does this inspect defects?
No.
Can the threshold be zero?
Yes, mathematically; that effectively removes that criterion.
Does recovery rate include scrap volume?
No. It expresses the potentially reusable portion of the measured volume.
