Code: HHW – Household Hazardous Waste (Special waste category)
Description: (Household Hazardous Waste) is the term environmental agencies use for leftover household products like paints, solvents, chemicals, and some batteries that can be toxic, flammable, corrosive, or reactive, and it is not about tenant heat and hot water service. These products need special handling and must not be thrown into normal trash, recycling, or poured down drains because they can harm people and the environment.
Practical Meaning: For a homeowner, HHW means certain leftover products—such as oil‑based paint, strong cleaners, pesticides, and some electronics—must go to a Special Waste Drop-Off site or SAFE Disposal Event, not into regular trash or recycling. Storing or throwing away these materials the wrong way can create fire risks, poison hazards, and fines if they cause a spill, fire, or illegal dumping situation.
Where You May See It: DSNY and NYSDEC guidance, NYC311 “Special Waste” and SAFE Disposal Event pages, county or state recycling guides, environmental flyers, and event notices about HHW collection days.
Why It Matters: Proper HHW disposal protects your home, neighbors, and the environment from dangerous chemicals, and helps you avoid problems if a fire, spill, or illegal dumping investigation traces back to your property. NYC also offers free or low‑cost HHW drop‑off and SAFE events, so understanding HHW rules can save you money on private disposal and reduce long‑term liability.
