Household Hazardous Waste (HHW)

Household hazardous waste (HHW) includes products that we purchase and use every day in our home that contain materials that can harm us or the environment. Common household products that are a HHW when discarded include fluorescent light bulbs, cleansers, electronics, medications, needles, pesticides, paints and stains. Look for words such as 'warning,' 'caution,' 'flammable,' 'toxic,' 'poison,' etc. on the labels. Many of these products may be partially used, then stored in your homes, basement or garage. The best option is to use all the products you buy.  However, if you have left over materials like this, it is best to take them to a local HHW collection instead of sending them to a landfill, if HHW collections are available. This will help protect both your family and the environment.

These pages contain information helpful to collecting discarded materials not subject to hazardous waste regulation.

 

You can reduce HHW by:

  • Checking the label before you buy. If you see a cautionary notice, understand that this material will become a household hazardous waste if not used up properly.
  • Using the product as the manufacturer instructs. Companies are required to test their products to comply with federal regulations. Directions should be followed to get maximum benefit from the products you use without compromising your safety.
  • Buying only what you need. Some products cost more to dispose than they do to purchase. So use forethought when purchasing products that may be costly for you or your community to dispose.
  • Storing products safely. Children, pets, and others may accidentally injure themselves if products are not safely stored. So make sure these types of materials are stored according to manufacturer instructions, out of harm's way.If you have questions about proper handling of household hazardous waste, contact your local HHW program, recycling coordinator, wastewater treatment plant or department of public works.  Use the links below to obtain information about the hazards associated with household products, where to find a HHW collection program, and what you can do to reduce hazards in your home and community.  The resources shared below are neither endorsed nor supported by the Michigan Department of Environmental Quality (MDEQ).  This list is provided to help you find more information about household hazardous waste management and provide general information about what you can do to protect Michigan's natural resources and your environment.

GENERAL HHW INFORMATION 

MATERIALS 

  • Batteries. Lead acid (such as car batteries), dry cell (commonly used in flashlights and toys), rechargeable (found in power tools, cameras, and phones), button batteries (found in hearing aids and watches) and more. Batteries are found everywhere and proper management is important to ensure they do not cause harm to us or the environment when we are through using them.  See the US DOT advisory of battery transport and consider taping the ends of dry cell and rechargeable batteries so they do not touch each other and potentially spark during transport.  The Rechargeable Battery Recycling Corporation sponsors free collection and recycling of rechargeable batteries throughout the country.
  • Cleansers.  Cleansers often have a very high or very low pH and can burn the skin.

  • Electronics.  Electronics, such as computers, computer monitors, televisions, laptops, VCRs, cell phones, printers, computer mice, remote controls, telephones, video games, fax machines, and printers, often contain toxic materials such as lead, cadmium, chromium, mercury, and fire retardants.  These products are commonly collected for recycling through HHW collections and other recycling/takeback programs. See www.michigan.gov/deqewaste for more information.  
  • Light Bulbs.  Compact fluorescent lights (CFLs) and traditional fluorescent bulbs are a popular way to reduce energy use.  However, fluorescent light technology and some high intensity discharge bulbs use mercury, making it important that these lights be managed properly when unwanted and that the mercury be recycled where possible. 
  • Medications.  Medications should be stored in their original containers and kept secure so they cannot be easily accessed by others.  When medications are no longer needed, they should be disposed through a residential takeback program where possible.  They should not be flushed down the drain.  Studies have shown that medications entering our wastewater are generally not removed by the wastewater treatment process.  Therefore, takeback programs that incinerate the chemicals are encouraged.  If a collection is not available follow our safe disposal recipe for disposing of unwanted medications in the regular trash.  The following resources and more are available at www.michigan.gov/deqdrugdisposal:
  • Medical Waste.  Unwanted needles and lancets, also called sharps can injure waste handlers if they are disposed in the trash or in a recyclable.  If possible, take unwanted sharps to a residential takeback program where they can decontaminate them prior to recycling or disposal.   
  • Mercury.  For decades mercury (Hg) has received attention as a serious pollutant because it is toxic and it bioaccumulates in living organisms. Take unwanted mercury containing items like thermostat switches or thermometer.  Where possible, take sharps to a residential takeback program where they may be decontaminate them prior to recycling or disposal.   
  • Paint.  Many HHW programs collect oil-based paint and associated liquids.  Latex paint does not normally contain materials considered hazardous and it is not normally collected at HHW collections.  When collected, it is generally collected and recycled.
  • Pesticides.  Pesticides are designed to be toxic, so they should be managed carefully and taken to a collection where that will provide for them to be incinerated, to destroy the chemicals in the pesticides. Be sure to follow the label instructions at all times as required by law. 
  • Used Oil Motor.  Oil picks up small particles of metal and dirt as it lubricates a car engine.  Since motor oil needs to be replaced periodically, recycling used oil is a good way to protect the environment and conserve this petroleum based product.
