Household Hazardous Waste

Household Hazardous Waste (HHW) is typically comprised of unused household products that may explode, catch fire, or be generally harmful to the environment if not properly disposed. Some examples of HHW are paint, pesticides, pool chemicals, drain cleaners, batteries, and motor oil. For a more complete description of HHW, check out our HHW explainer. The following list includes some general guidelines for reducing the environmental risks associated with the use of these materials:

  • When purchasing paint, pesticides, pool cleaners, etc., try to avoid buying more materials than are necessary to complete the job
  • Avoid mixing leftover HHW materials with other products
  • Check product labels for safety and handling instructions
  • Consider donating unused HHW materials to local organizations

  • DEP strongly urges residents of the commonwealth to properly dispose of their unwanted HHW materials. However, if your community does not have a collection program or you must discard the materials prior to the next scheduled event, you may legally discard them in your regular trash pickup, provided:
    • You have read the label and complied with any disposal directions.
    • Liquids have either been allowed to evaporate (if water based) or absorbed (if non-water based) on some material such as vermiculite, cat litter, or sawdust, so that there are no freestanding liquids).
    • The remaining residue has been packaged to prevent leakage while the material is being transported to the disposal facility
    • The material is placed out in small quantities, over several collection periods.
