How much drywall waste does a project produce?

Industry sources estimate that about 10 to 15 percent of drywall delivered to a project ends up as trim scrap, plus whatever is torn out.

Should I keep drywall dry?

Yes. Wet drywall is heavier, harder to recycle, and wet gypsum in landfills can produce hydrogen sulfide gas.

Can old drywall contain asbestos?

In homes built before the 1980s, joint compound and some textured finishes may. Have suspect material tested before tearing it out.

Drywall Disposal and Recycling: A Practical Guide

Q: Can drywall go in a dumpster?

In most places yes. Massachusetts bans clean gypsum wallboard from disposal and Seattle bans new construction gypsum scrap from C&D garbage; there it must be recycled.

Two kinds of drywall waste

Demolition drywall: old board torn out of walls and ceilings. It is often painted, papered or taped, may have nails and screws in it, and can be mixed with insulation. Harder to recycle.
New construction scrap: clean offcuts from installing new board. Clean gypsum scrap is the most recyclable form.

Industry sources estimate that roughly 10 to 15 percent of the drywall delivered to a project ends up as trim scrap. On a big remodel or new build, that adds up.

How heavy is drywall?

Gypsum board is heavier than it looks. A standard sheet weighs roughly 50 to 70 pounds depending on thickness and size, and wet drywall is much heavier. A room’s worth of torn-out board can weigh several hundred pounds; a whole-house gut, several tons. For most remodels, drywall fills a container by volume before weight – unless it is wet or mixed with plaster.

Can drywall go in a dumpster?

In most places, yes. Drywall is standard construction debris and is accepted in roll-off containers. A few things to know:

Massachusetts: the state bans clean gypsum wallboard from disposal at solid waste facilities; it must be recycled. Mixed loads go to facilities that sort it out.
Seattle: the city bans new construction gypsum scrap from disposal in C&D garbage containers; it must go to recycling or a qualified facility.
Recycling rules elsewhere: California’s CALGreen and several city ordinances require high recycling rates for construction projects, which often includes clean drywall scrap.

Ask the provider whether they want clean drywall kept separate. Clean scrap can often be recycled more cheaply than mixed debris is disposed of.

Why keep drywall dry and separate?

Wet gypsum in landfills can produce hydrogen sulfide gas, which is one reason some facilities and states prefer to keep gypsum out of landfills and recycle it. For you, the practical reasons are weight – wet drywall is heavy – and price: a clean, dry load of new scrap is the easiest kind to recycle.

Recycling options

Gypsum recycling facilities: some regions have processors that grind clean scrap back into gypsum for new board, cement production or agricultural use.
Manufacturer take-back: some drywall manufacturers accept clean scrap from large projects.
Soil amendment: clean, unpainted gypsum can be used as a soil amendment in some agricultural settings. Don’t spread old painted board in your garden.
Your hauler: the simplest option for homeowners – ask whether they take clean drywall separately to a recycler.

Old drywall: test before tearing out

In homes built before the 1980s, joint compound and some textured wall and ceiling finishes may contain asbestos, and old paint may contain lead. The EPA recommends testing suspect material before a remodel disturbs it. If the tests are positive, removal must be done by trained professionals and the waste handled separately – not in a regular dumpster.

How to load drywall efficiently

Break sheets flat, don’t crumble them; flat pieces stack tightly.
Remove large nails and screws where practical, or at least bend them over for safe handling.
Keep insulation separate if the provider asks; it is bulky and light.
Cover the container in rain so the drywall stays dry and light.
Bag the dust and small pieces for cleaner handling.

Container size for drywall-heavy projects

One room tear-out: a 10 yard container or less.
Several rooms or a basement: 15 to 20 yards.
Whole-house gut: 20 to 30 yards, often in several hauls, especially with plaster.
New construction: a smaller container dedicated to clean scrap may be worth it where recycling is available.

Dust and safety

Cutting and breaking drywall creates fine gypsum dust. Wear a dust mask or respirator and eye protection, seal off the work area with plastic, cover HVAC vents and use a shop vacuum with a fine filter for cleanup. Wet-wiping surfaces afterwards picks up dust that sweeping spreads around.

Drywall in water-damaged homes

After a leak or flood, drywall that was soaked usually has to be cut out – typically in a straight line some distance above the visible water line – along with wet insulation behind it. The EPA advises drying wet building materials within 24 to 48 hours to limit mold; drywall that stays wet longer often grows mold on the back side. Wet drywall is heavy and crumbly: bag it, tell the provider it is water-damaged, and photograph the damage for your insurer before removal. See storm debris cleanup.

Who handles drywall waste on a remodel?

On most professional remodels, the drywall contractor or general contractor removes scrap as part of the job, often in their own container. If you are acting as your own general contractor, clarify in each trade’s agreement who is responsible for debris, so scrap doesn’t pile up in the garage.

Plaster versus drywall

Homes built before about the 1950s often have plaster walls on wood or metal lath instead of drywall. Plaster is much heavier and dustier than drywall, and the lath adds volume and nails. A plaster tear-out fills a container’s weight allowance far faster than the same wall area of drywall. If you are gutting an older home, tell the provider it is plaster, choose the container by weight, and plan for more than one haul.

Estimating drywall from a remodel

Drywall is usually counted in sheets. Measure the wall and ceiling area you are removing or installing and divide by the sheet size – 32 square feet for a 4-by-8 sheet or 48 square feet for a 4-by-12 sheet. A typical 12-by-12-foot room with 8-foot ceilings has about 384 square feet of walls plus 144 square feet of ceiling – roughly 17 sheets of 4-by-8 board before openings. For new installations, the 10 to 15 percent trim scrap estimate gives you an idea of how much waste to expect.

Small amounts

For a few pieces from a repair, many cities accept small amounts with regular trash if bagged and under weight limits – Kansas City, Missouri, for example, allows sheetrock or plaster in bags under 40 pounds with weekly trash. For anything more, a container or hauler is the way.
