Solid Waste and Recycling Info


How do I dispose of.. ?

Bring it to the Recycling Center. The antifreeze must be clean and clear. If it is contaminated with any other type of waste (i.e. oil or gasoline) it must be disposed of as a hazardous waste.

Portsmouth residents can recycle rechargeable batteries through an organization called Rechargable Battery Recycling Corporation (RBRC).  There are two drop-off boxes from the company located at the Recycling Center another at the Department of Public Works. 

Place each individual rechargeable battery, or cell phone with battery, into a separate plastic bag (provided at the drop –off box).  Drop the battery into the box.

Cooking Oil?

Residents can recycle used cooking oil under a new City pilot project with a company that will convert it into bio-fuel for vehicles and home heating. Used or unwanted cooking oil should be taken to the City's Recycling Center, where City personnel will provide assistance. Bean's Commercial Grease Incorporated has provided a storage drum for the cooking oil, which will be taken to Bean's New England facility to be refined for reuse.

Computer Monitors and TVs?

Computer monitors and television sets both have cathode ray tubes, which contains heavy metals, including lead, mercury and/or cadmium. Therefore they cannot be disposed of in the landfill with regular household rubbish. Bring your unwanted electronics to the Recycling Center or Call DPW to schedule for curbside Bulky Waste. There is a nominal fee for disposal of electronics. For more information on the hazards of cathode ray tubes, click here.

Fluorescent Light Bulbs?

These lights contain mercury and proper disposal is essential.  You may bring your old bulbs to the Recycling Center. For operating hours of the Recycling Center please click here.  Please ask the attendant for instructions where to place the bulbs.  For more information on the hazards of mercury and/or how to clean up spilt mercury, click here Mercury

Medical Waste?

Emptying the Medicine Cabinet
Disposal Guidelines for Pharmaceuticals in the Home

The approach for the proper disposal of medicine promotes not storing unneeded medicine; not flushing medicine or pouring down the drain; rendering medicine unusable and disposing of unneeded medicine in an appropriate manner as described below:

  1. Pour medicine into a sealable plastic bag.
  2. If the medicine is a solid, add a small amount of water to dissolve it.
  3. Add coffee grounds, kitty litter or something similar to the liquid medicine in the plastic bag.
  4. Seal the bag and immediately dispose of it in the trash.
  5. Use a marker to black out any personal contact information on the empty medicine container prior to disposing of it in the trash.
  6. For more information, consult www.nh.gov/medsafety  Disposal information for household generated sharps may also be found on this website.

To reduce the amount of waste pharmaceuticals:

  1. Only purchase what you need. Why waste money on pharmaceuticals to just sit on the shelf and expire over time?
  2. Say “No” to samples if you are not going to use them. You will only need to dispose of them later.
  3. Stop junk mail. Take your name off mailing lists so you don’t receive free sample products, such as pain relievers. If you don’t use them, then you will need to dispose of them later. Visit www.des.nh.gov and search on “junk mail” to find out how.
  4. Centralize all pharmaceuticals in one location. This may help to limit over purchasing of products you already have (and save you money, too!)

Household Generated Sharps
Household generated sharps may be disposed of in the solid waste, provided:

  1. Sharps are enclosed inside rigid, puncture resistant containers, such as an empty liquid laundry detergent or bleach container.  Also, containers can be purchased that are specifically designed for the disposal of sharps. Before placing a container of sharps in the trash, reinforce the lid with heavy duty tape and place the container in a securely fastened plastic bag.

Containers encasing sharps are sealed and labeled “not for recycling.”  For more information, visit www.nh.gov/medsafety and for a flyer click here.

Paint?

OIL based paint is a hazardous waste and must be disposed of accordingly.  Twice a year the City of Portsmouth provides hazardous waste disposal services, via Household Hazardous Waste Collection (click here) for more information on hazardous waste and the next collection date.

Latex paint in its liquid form is hazardous and cannot be thrown away with household trash.  But latex paint, once hardened, no longer displays hazardous characteristics and can be disposed of just like any other solid waste item.

NOTICE, the paint must be hardened all the way through.  If you leave the lid of the paint can open for a few days, it will harden – but only on the surface.  The core may still be liquid. 

One way to expedite the hardening process: go to your local hardware store, in the paint section, you can find packets of paint hardener.  Add it to the paint.  When the paint becomes solid, bring it to Portsmouth’s Recycling Center for disposal in the trash.

We ask you to bring it to the Recycling Center, instead of putting it curbside for rubbish collection because we need to make sure the paint is truly hardened.

  

Shingles, Roofing?

Answer: Public Works is not set up to handle this type of waste.  You can dispose of shingles at the Aggregate Recycling Corp in Eliot, ME. Call 207-439-5584.

Smoke Detectors?

According to the U.S. EPA, both photoelectric and ionization smoke alarms contain plastic, electronic circuit boards, radioactive material and in some cases, batteries. When it comes time to dispose of your device, it’s important to know that ionization chamber smoke detectors (ICSDs) cannot be recycled, due to their radioactive content. For this reason, it is extremely important to properly dispose of the unit. Do this by:

  1. Removing the battery and recycling it.
  2. Safely removing the plastic cover, and recycling it with your other plastic casing.  If it has the recycling symbol – the chasing arrows with a number – 1 thru 7, the casing can be recycled with other plastics curbside.  If there is no chasing arrow and number, dispose of it in the trash).
  3. Sending it back to the manufacturer, who will properly dispose of it. The address of the supplier is usually listed in the product warranty or user’s manual.
  4. If you no longer have the manufacturer information try contacting one of the big box home goods stores, such as Home Depot or Walmart - they frequently look to be good neighbors and often offer take back programs to be more “green”. 
  5. Please note, the City cannot accept smoke detectors at the Household Hazardous Waste collection events, the contractor is not permitted to ship low levels of radioactives.   AKPC_IDS += "4953,";

Tires?

Portsmouth residents may bring tires to the Recycling Center. There is a nominal fee for disposal of tires.

Used Oil and used oil filters?

1) collect and store your used oil in an empty steel or plastic container - but not one that was used previously to store chemicals
2) bring it to the Recycling Center there is a large gray tank, marked with a sign, "Used Oil". Place your container(s) on the pallet next to the tank and Public Works employees will take it from there.

Do not dump any other materials into the tank. This will contaminate the entire contents and we will have to dispose of it as a hazardous waste, which in turn costs you tax dollars.
