Gypsum Waste tonnage as delivered.
About 0.25 short tons per cubic yard (500 lb/yd³) for broken plasterboard thrown loose into a container; published C&D factors run 394-500 lb/yd³. The board itself is roughly twice as dense.

About 0.25 short tons per cubic yard (500 lb/yd³) for broken plasterboard thrown loose into a container; published C&D factors run 394-500 lb/yd³. The board itself is roughly twice as dense. Light bulky materials fill a container by volume long before they reach its weight limit.
- Conversion factor applied
- 4 yd³ per short ton

How this was calculated
Formula source(s)
- Inverse of approximately 0.25 short tons per cubic yard
- 1 short ton = 2,000 lb; a metric tonne is about 10% heavier
Inputs used
- Gypsum Waste weight (short tons)
- 10
Intermediate steps
- Conversion factor applied
- 4 yd³ per short ton

What this calculation does not cover
- A skimmed or dot-and-dabbed strip-out is not the material behind this figure. Set skim, and the adhesive dabs on the back of a direct-bonded lining, are denser than the board they are stuck to, so that tonnage occupies fewer cubic yards than the result gives — size a container from it and you hire more space than the load fills.
- Rated capacity and usable capacity are not the same number. Some yards quote a container level and others quote it heaped, and how far a load may sit above the rim is a matter of the hire terms and the local haul rules rather than of the box, so establish which basis the rating uses before you match these cubic yards to a size.
- The disposal route decides which container these cubic yards can go in. Where gypsum has to be kept out of mixed waste, board needs a container of its own and cannot be absorbed into the general skip already standing on site, so even a small volume arrives with its own hire and its own collection.

Converting a gypsum waste tonnage into volume shows how much container space it will occupy, which on a boarding job is a great deal. Because the material is light and bulky, the practical saving comes from generating less of it: planning board layouts to reduce offcut, and using longer sheets where walls suit them, cuts both the material bill and the disposal cost. Offcuts large enough to reuse are worth keeping rather than skipping.
