It’s a common assumption that a county government runs local recycling and waste rules, and in a lot of states, it does. New Hampshire isn’t built that way. Hillsborough County — Nashua’s own home county — has no land-use or waste-management authority at all; every town here, including Nashua itself, runs its own trash and recycling program independently. What actually governs disposal statewide, across every town in Hillsborough County and beyond, is the New Hampshire Department of Environmental Services, known as NHDES. This guide covers what NHDES actually restricts, and where those restricted items go, rather than pointing you toward a county office that doesn’t handle any of it.
Your Dumpster and These Rules Do Different Jobs
A dumpster rental is built for volume — the bulk of a cleanout, remodel, or construction job, delivered to your driveway and hauled away in one trip. NHDES’s two real, statewide bans cover a much shorter, more specific list of items that need separate handling, not general household debris. Most projects around Nashua need both: a dumpster for the bulk of the job, and a separate stop — often just an item or two — for whatever falls under one of the two rules below.
The Video Display Device Ban: Real, Active, Statewide
New Hampshire bars video display devices from ordinary landfill or incinerator disposal — a real, long-standing, statewide rule, not a takeback suggestion. That covers televisions, computer monitors, any screen over 4 inches diagonal, and computer CPUs. None of these can go in your roll-off dumpster or your household trash. If a cleanout turns up an old TV, a monitor, or a desktop tower, set it aside as its own small pile rather than mixing it into general debris — it needs a certified electronics recycler or a participating retailer instead.
The Lithium-Ion Battery Ban: New as of July 1, 2025
A newer statewide rule took effect on July 1, 2025: NHDES bars disposing of rechargeable lithium-ion batteries in the trash, landfill, or incinerator. This covers the battery packs inside phones, laptops, cordless power tools, e-bikes, and plenty of other everyday devices, and it applies to both households and businesses. This isn’t just a recycling preference — a punctured or crushed lithium-ion battery pack is a genuine fire risk in a collection truck or at a transfer station, which is exactly why the rule exists. The right path for these is a certified recycler, a Call2Recycle drop-off point, a participating retailer such as Best Buy or Staples, or your local transfer station. If a job you’re clearing out includes old cordless tools, laptops, or similar battery-powered devices, pull those batteries aside before the dumpster fills in around them.
Asbestos: Never in a Roll-Off, No Exceptions
Asbestos is the one category with no gray area and no recycling workaround. It’s never permitted in any container, of any size, for any reason — older insulation, certain floor tiles, and some roofing or siding materials in homes built before the 1980s can contain it, and disturbing or hauling it without proper handling creates a real health risk. If a renovation or demolition on an older property turns up suspected asbestos-containing material, the right move is a licensed abatement contractor, not a dumpster, regardless of how small the amount seems. Mention it to us before delivery if you know or suspect it’s part of the project.
Paint, Fuel, Chemicals, and Medical Waste
Paint, fuel, motor oil, other household chemicals, and medical waste are all standard prohibited items in any roll-off dumpster, the same as they are everywhere else. If a garage or shed cleanout turns any of these up, plan on a separate disposal path for them rather than loading them into the container with everything else.
Crossing Into Massachusetts
Three towns in our service area — Tyngsborough, Dunstable, and Pepperell — sit across the state line in Massachusetts, which runs its own solid waste program through MassDEP rather than NHDES. If your project is in one of those towns, the video display device ban and the lithium-ion battery ban above are New Hampshire rules and don’t automatically carry over; MassDEP sets its own requirements, so it’s worth confirming current rules with them directly rather than assuming the New Hampshire list applies as written.
What Belongs in Your Dumpster
Outside the categories above, the list of what you can put in a roll-off is long: furniture, cabinetry, flooring, drywall, general construction debris, yard waste, and standard household junk are all fair game across our size lineup. For the complete breakdown by category, see our guide on what can go in a dumpster in New Hampshire.
Where Permits Fit Into This
None of the disposal rules above change anything about where a dumpster itself can sit. Placement entirely on private property still needs no permit anywhere in our service area; street placement runs through whichever town’s own office handles it, since neither Hillsborough nor Rockingham County has any permitting authority here either. Our permit guide covers that by town.
Sorting It Out Before Your Container Arrives
When you call to book, mention anything you know is coming out that might fall on this list — an old TV, a stack of cordless tool batteries, a laptop that’s seen better days — and we’ll tell you up front what needs a separate path rather than having it turn up as a problem on pickup day. Call us at (603) 704-3257, or see our junk removal and estate cleanout pages if your project is likely to turn up a mix of these items.
