Gypsum Waste Cubic Yards to Tons Calculator

Convert a gypsum waste volume into short tons for ordering, disposal and transport planning.

Approximate weight

5 short tons

High confidence

About 0.5 short tons per cubic yard for broken plasterboard offcuts; light but bulky waste. A planning figure, not a specification. Confirm the figure with your supplier or waste contractor before relying on it.

Conversion factor applied
0.5 short tons per cu yd

Plasterboard offcuts are among the bulkiest waste streams on a fit-out, and they are light enough that containers fill by volume long before they approach a weight limit. Gypsum also has to be segregated: most jurisdictions require it to be kept out of general mixed waste, because in landfill conditions it can generate hydrogen sulphide. Planning a separate container for board offcuts is therefore a compliance matter as much as an efficiency one.

Add the equipment this sizes

This result is a specification — 5 short tons — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Why must gypsum be separated?
Because in anaerobic landfill conditions gypsum can generate hydrogen sulphide, so most jurisdictions require it to be kept out of mixed waste. Segregation is a compliance requirement rather than a preference.
Can plasterboard be recycled?
Yes, where facilities exist — clean offcuts can be reprocessed into new board. Contamination with plaster skim, tape or insulation reduces or eliminates its value, so keeping the stream clean matters.
How do I generate less board waste?
Plan the layout before cutting and use sheet lengths that suit the walls. Longer boards on long walls produce fewer offcuts as well as fewer butt joints, so the same decision improves both waste and finish.
