Frequently Asked Questions

Frequently Asked Questions

If you don't find the answer to your question on our website, please contact Emma Rearick at 603-417-6570.


Household Hazardous Waste User Fee

User Fees = $15 per vehicle, for up to 10 gallons or 20 pounds of hazardous waste.
If you bring more than 10 gallons or 20 pounds you will be asked to pay an additional fee.

We accept cash or check. Please make your hazardous waste check payable to "NRSWMD."

Carpooling is encouraged. If you and your neighbors collectively have less than 10 gallons or 20 pounds of materials and you carpool in one vehicle, you’ll only be charged $15.00 total.

*Note: User fees apply to residential customers only.  Businesses participating in the Small Quantity Generator program will be charged directly by our hazardous waste vendor based on materials and volumes. Pre-registration is required at least 2 weeks in advance. See FAQ: "Who Can Participate" for more information.
Why is there a fee to participate in the HHW collection?
The Nashua Region Solid Waste Management District (NRSWMD) spends roughly $95 per household on disposal costs alone for each HHW event.  The NRSWMD receives a majority of its funding through municipal tax assessments and grants. However, the safe disposal of HHW is expensive, and these sources do not cover all of the program costs. Also, grant funding to subsidize the program is never guaranteed, so in order to ensure we can continue to offer a full collection schedule we ask participants to help offset the program costs with a $15 user fee.  We sincerely appreciate your support and participation, without which this program could not continue.
Is there a reduced fee for bringing only a few items? What about a senior discount?
Unfortunately, we do not have the ability to reduce fees below the standard $15.00 price. We do recommend that you "wastepool" with friends or neighbors to maximize your user fee and reduce vehicle trips to the event.
What forms of payment do you accept for HHW user fees?
We accept cash or check. Checks for the $15.00 HHW fee should be made payable to "NRSWMD" (Nashua Region Solid Waste Management District).

What is Household Hazardous Waste (HHW)?

What is HHW?
Household Hazardous Wastes (HHW) come from everyday products used in the home, yard, or garden. Oil-based paints, solvents, auto products, antifreeze, pesticides, gas, and household cleaners are just a few examples.  NRPC holds HHW Collections to allow residents to properly dispose of these products.
By definition, household hazardous waste is corrosive, flammable, toxic, or reactive.  When you are purchasing household products, be sure to read the labels carefully and avoid items with any of these properties.  

 corrosive  flammable.png  toxic.png  reactive
Corrosive substances will destroy or irreversibly damage other substances they come in contact with. They can damage eyes, skin, and tissue, with exposure resulting in chemical burns. Inhalation or ingestion can damage the respiratory and gastrointestinal tracts.

Look at the Label
Words such as “causes severe burns on contact” or “can burn eyes, skin, throat” indicate a product is corrosive.
Flammable substances can burn or ignite, causing fire. Solids, liquids, and gases can all be flammable. Flammable materials should never be used or stored near sources of heat, flame, sparks, static discharge, or in unventilated areas.

Look at the Label
Words such as “don’t use near heat or flame,” “combustible,” and “do not smoke near this product” indicate a product is flammable.
Toxic substances are capable of causing injury or death through ingestion, inhalation, or absorption. Many household cleaning products are toxic. In fact, cleaning products were responsible for almost 10% of all toxic exposures reported to Poison Control Center in 2000.

Look at the Label
Words such as “harmful or fatal if swallowed” or “use only in well ventilated areas” indicate a product is toxic.
Reactive substances can spontaneously ignite or create poisonous vapors when mixed with other products. They can also explode when exposed to heat, light, sudden shock, or pressure.

Look at the Label
Fortunately, with the exception of fireworks, most current consumer products are not reactive. The word reactive will likely appear on the label.
How can I identify hazardous materials in my home?
When you see the words "caution," "poison," "warning," or "danger" on a product label, you are dealing with a potentially hazardous material that cannot be disposed of as regular waste.

These products often have one or more of the following properties:
  • Flammable: easily ignited or set on fire
  • Corrosive/Caustic: can cause burns or destroy living tissue through contact
  • Explosive: may explode if exposed to heat or pressure
  • Toxic: may cause injury or death if inhaled, ingested, or absorbed through skin
Why can't I dispose of household hazardous waste in the same manner as my regular trash?
Household hazardous waste needs to be treated differently than regular waste items because it contain chemicals or has properties that are hazardous to human health or the environment if not managed properly. Improperly disposed of materials (such as dumping down the toilet, drain, or storm sewer) can damage sewer treatment plants or private septic systems. Materials may flow directly into streams and ponds, which are common sources of drinking water. Materials that are incorporated into the solid waste stream with regular trash can commingle, ignite, and explode.
How can I reduce the amount of household hazardous waste in my home?
First, become familiar with labels and their code words. Products that include "flammable, corrosive, explosive, or toxic" in their labels are likely hazardous, as are most aerosol products. Products that would not be considered hazardous often have the word "nontoxic" on the label. Purchase nontoxic substitutes when possible and stay away from hazardous items. Click herealternatives.html for earth friendly alternatives.

When no substitute product is available, purchase only the quantity of product that you need to complete the job at hand. If you end up with leftover product despite your best intentions, donate it to a friend, relative, or community group that might need the item for their own purpose.

Collection Events FAQ

Antifreeze, Batteries, CRTs, Bulbs, & Mercury Containing Devices
Antifreeze, Batteries, CRTs, Bulbs, & Mercury Containing Devices
1. Do not put these items in your household trash. They contain mercury, lead, cadmium, and other substances that are hazardous to human healthy and the environment.

2. Check with your municipality to see if they can accept these items. In many cases it is less expensive to dispose of them through your municipality than it is to bring them to a house-hold hazardous waste (HHW) collection. Help keep HHW disposal costs down.

3. Cathode ray tubes are NOT accepted at HHW collections. All other items can be brought to a HHW collection if they cannot be disposed of through your municipality. For more info visit or call 603-417-6570.

4. If you have a broken mercury thermometer, you may bring it to the hazardous waste collection events. Be careful when cleaning up and transporting the mercury because mercury vapors are toxic. Make sure to double-wrap the mercury-containing elements in plastic so that vapors cannot leak out. Label the container with a description of the materials contained, making sure to note the presence of liquid mercury. Click here for instructions for cleaning up a small mercury spill.

Alternative Automotive Products

Alternative products do exist, such as motor oil made from  saturated fats, wiper fluid made from bio-matter, and brake fluid made from vegetable oil.  Unfortunately, these products are often difficult to find.  NRPC surveyed a number of auto parts stores in the region and none carried these products.  It is up to us as consumers to begin asking for these products.  If there is enough demand, stores will stock them.

NRPC was able to find one environmentally friendly auto product that is available locally.  SIERRA Antifreeze is made from propylene glycol, which is less toxic than ethylene glycol, the standard ingredient in antifreeze.  SIERRA can be purchased at NAPA and Ace Hardware.

Compact Fluorescent Bulbs

Fluorescent Bulb Pricing/Invoice
For large quantities of bulbs, use this form.

Benefits of CFLs

  • CFLs last up to 10 times longer than incandescent bulbs.
  • CFLs use up to 75% less energy than incandescent bulbs.
  • This adds up to money savings for you!

Why Recycle CFLs?

  • CFL bulbs can break when thrown in the trash, releasing mercury into the
    environment.  Recycling CFL bulbs prevents the risk of mercury release.
  • When recycled, many components of the bulb are reused, including glass & metal. 
  • NH law prohibits mercury containing bulbs from being placed in landfills.

How to Recycle CFLs

  • Bring unbroken bulbs to your local transfer station.  Please contact your local transfer station to determine if you can recycle bulbs there instead of bringing them to a Household Hazardous Waste collection. 
  • Bring unbroken bulbs to a Household Hazardous Waste collection. 

Why is Mercury Used in CFLs?

  • Mercury is an essential element to allow CFLs to be an
    efficient light source.
  • The amount of mercury used in CFLs has fallen over 20% in the past few years.  There is an average of 4 mg of mercury in each bulb, compared to 500 mg in old thermometers.
  • No mercury is released from CFLs when they are intact or in use. 

Why is Mercury Harmful?

  • Mercury can damage the central nervous system, endocrine system, kidneys, and other organs.
  • Exposure over long periods of time or heavy exposure to
    mercury vapor can result in brain damage and death.
  • Mercury is particularly toxic to infants, young children, and pregnant women.

CFLs Can Actually Decrease Mercury in the Environment

  • Electricity use is the main source of mercury emissions in the US.
  • The EPA estimates the US is responsible for the release of 103 metric tons of mercury emissions annually.  More than half of these emissions come from coal fired electrical plants. 
  • CFLs use less electricity than incandescent bulbs.  As a result of this decreased electricity demand, CFLs reduce the amount of mercury in the environment.

Fertilizers & Pesticides
Why Worry?


  • According to the US Fertilizer Institute, annual revenue for the fertilizer business is $10 billion.
  • The US is the second largest consumer and producer of fertilizer behind China. 
  • The US agriculture industry uses roughly 800 million pounds of pesticides annually.
  • Roughly 90% of US households use pesticides of some form.  Homeowners in the US use roughly 70 million pounds of pesticides annually on their lawns.


  • When fertilizers enter a water body, they promote the increased growth of aquatic plants.  As these plants die, the dissolved oxygen content of the water decreases, which suffocates and kills fish. 
  • The algae that proliferates as a result of fertilizer contamination in water bodies can be toxic.  Blue-green algae, for example, can cause rashes, nausea, and respiratory problems in humans and can kill livestock and pets that drink affected water. 
  • When pesticides are dumped down the drain, septic, or sewer, they contaminate the water supply, harming humans and wildlife. 
  • Each year, 110,000 pesticide poisonings are reported to poison control centers in the US and 23,000 people go to the emergency room as a result. 
What's the Alternative?


  • Test your soil regularly.  It’s the only way to know what’s already there.  If you have sufficient amounts of nutrients then you don’t need more.
  • Know the nutrient needs of your plants.  Providing more nutrients than a plant needs will not help it to grow and will likely be unused.  Unused fertilizer can wash into lakes, rivers, and streams, and leach into ground water. 
  • Pay attention to time.  Only apply fertilizer during periods when plants will use it. 
  • Skip store bought fertilizer.  Use compost or plant debris instead.  Placing dried leaves on top of garden plots in the fall creates great fertilizer by spring.


Ants ~ red chili powder at entry points

Fleas & Ticks ~ scatter pine needles, fennel, rye, or rosemary on pet beds

Flies ~ keep a well watered pot of basil nearby

Insects on plants ~ soapy water on leaves then rinse

Mosquito repellant ~ citronella candles

Rodents ~ “Havahart” or other humane live animal traps

Slug/snail/nematode repellant ~ onion and marigold plants

What to Do?
If you are discarding pesticides and fertilizers on the ground, into a storm drain, or even placing them in the trash in a sealed container, you are disposing of them improperly. 

  • Use it up.  The best way to dispose of fertilizers and pesticides is to use them as they were intended.  Avoid overuse by purchasing the smallest amount possible to complete your job. 
  • Control erosion.  Be extra cautious when applying fertilizer and pesticides on slopes.  Control runoff into streets and storm drains to prevent surface water contamination. 
  • Store fertilizer and pesticide properly.  Keep these products under a shelter and off the ground so they can’t be washed away by the rain.  Follow manufacturer’s instructions for proper storage.
  • Contact the manufacturer.  Some companies offer programs to take back outdated products or empty containers. 
  • Do not rinse empty pesticide containers or place them in with household recycling.  Instead, bring empty containers to an HHW collection.


If you do find yourself with products that you cannot use, bring them to a Household Hazardous Waste collection.  See the reverse for a complete schedule.  Accepted items include herbicides, fertilizers, insecticides, No-Pest strips, pesticides, and rodent killers.

Latex Paint Disposal Guide

Latex Paint Disposal Guide

How do I know if my paint is latex?paint can

Look for Key Words—if your paint is latex, it will have the words “latex,” “water-based,” or “acrylic” on the can.  Non-latex paint will say “oil based” or “alkyd.” 

Check Clean-up Instructions—if you can’t find the words “latex,” “water-based” or “acrylic,” check the label for clean-up instructions.  Latex paint cleans up with soap and water.  Oil-based paint requires cleanup with paint thinner, turpentine, mineral spirits, or solvent.

What if I still cannot tell if it is latex?
If you cannot read the label, assume the paint is oil-based and bring it to a Household Hazardous Waste collection. 

How do I dispose of unwanted latex paint?
Latex paint is not accepted at Household Hazardous Waste events, but you can safely and easily dispose of it yourself.  Liquid latex paint cannot be thrown away.  Instead, dry it out using the following techniques.  Once dried, latex paint and cans may be taken to your local transfer station or landfill for disposal.krud kutter

# If the paint can is less than 1/4 full, harden the remaining paint using an absorbent material such as kitty litter, newspaper, or sawdust.

# If very little paint remains, remove the lid and allow the paint to air dry.

# For larger quantities of paint, line a cardboard box with plastic and fill with a thin layer of paint (about 1 inch deep).  Add shredded newspaper and allow paint to harden.  Repeat this process one layer at a time until all of the paint has hardened.   You can also purchase a commercial waste paint hardener at your local home improvement store to help dry latex paint.paint hard

Why can’t I bring my latex paint to a household hazardous waste collection?
Today's latex (water-based) paint has a very low level of toxicity and is not considered household hazardous waste when dried.  Disposing of it at a household hazardous waste collection day is very expensive.  Therefore, we ask people with unwanted latex paint to use other options to dispose of it.

Can I get my containers back after the contents have been disposed of?
Yes, just let the staff know which containers you would like to keep.
Should I bring empty bottles/cans/containers that once held HHW to the collection?
If the container is truly empty, you can dispose of it with regular household trash and you do not need to bring it to a HHW collection.
Do you accept styrofoam peanuts or packing materials?
Styrofoam is not accepted at HHW collections since it is not acutely corrosive, toxic, flammable, or reactive in its normal form. However, that doesn’t mean Styrofoam is good for our environment. It can pose significant risks to fish and wildlife and it takes a very long time to biodegrade.

Styrofoam is difficult for municipalities to handle as a recyclable material because it is bulky and hard to store. No municipal facilities in the NRPC region are currently able to recycle Styrofoam materials.

Many packaging companies (UPS, Mailboxes etc.) gladly take packing peanuts and Styrofoam materials for reuse. Give your local packaging store a call to see what their policy is. If you have some storage space, keep these materials for reuse yourself. You can also contact the parent company when you receive a new item that is packaged in molded Styrofoam bricks (like a DVD player, or coffee maker) to see if the materials can be mailed back for reuse. Finally, avoid Styrofoam altogether and instead opt for more environmentally friendly cornstarch peanuts (they simply dissolve away in water) or paper shreds.
How can I safely dispose of lead paint chips?
Lead paint, in either dried or liquid forms, cannot be disposed of with your regular trash. You can bring lead paint chips to a HHW collection. When remodeling, remember to minimize the risk of lead poisoning, especially if the paint is chipping or pealing. Never dry-sand, dry-scrape, or burn lead paints and consider hiring a certified professional contractor to remove and safely dispose of lead-based paint.
How should I package my items for the collection?
Materials should be kept in their original containers with original labels, if possible. Make sure that caps and lids are secure, and place any items at risk of tipping or spilling in an upright cardboard box lined with a garbage bag. Since many chemicals have noxious odors, we recommend that materials be kept in the trunk or rear of the vehicle. Do not store materials in a very hot or very cold vehicle or in direct sunlight. Smoking is not permitted once inside the facility gates.
Why do I have to fill out a survey to participate in the HHW collection?
The data allows us to apply for grant monies to help fund the collections and is required by the State. The survey also helps us objectively evaluate our collection program and identify any areas that need improvement. The survey is easy to complete and does not ask for personal or incriminating information.
Who operates the household hazardous waste collection?
The Nashua Regional Planning Commission (NRPC) organizes and staffs the household hazardous waste collection program on behalf of the Nashua Regional Solid Waste Management District (NRSWMD). The NRSWMD was formed in 1988 specifically to address the problem of how to safely and legally dispose of household hazardous waste. The NRSWMD is comprised of the towns of Amherst, Brookline, Hollis, Hudson, Litchfield, Merrimack, Milford, Mont Vernon, Nashua, Pelham, and Windham.
Why doesn't my town accept household hazardous waste at the landfill / transfer station?
Household hazardous waste (HHW) is different than regular trash and requires specific handling and disposal techniques to ensure that it is safely managed. When improperly handled, HHW can cause explosions, fires, or toxic releases that threaten air, water, and soil quality. State and federal laws prohibit the disposal of hazardous waste in municipal landfills and regulate the transport of hazardous wastes when they occur in large quantities or are industrially produced.

As a result, it can be very expensive to safely dispose of HHW, so few municipalities have the facilities, training, or funding to host their own collections or to process materials on site. By working together through the District, municipalities are better able to afford to offer collection events.
Are there other locations in the State of NH where household hazardous waste collections take place?
The NH Department of Environmental Services compiles information on all of the household hazardous waste collections taking place throughout the state. If you are moving soon and can't make any of these collections, we recommend asking friends or neighbors to store your HHW materials and bring them to a regularly scheduled event for you.
