Household Hazardous Waste

Disposing of toxic materials in your trash, down the drain, or on the ground can seriously impact our environment and public health. Household hazardous wastes can contaminate septic tanks, wastewater treatment systems, ground water, and even our drinking water if not disposed of properly. Household hazardous wastes are leftover household products that are toxic, ignitable, corrosive, or reactive, such as – cleaners, paint, pesticides, adhesives, polishes, and fuels.

Household Hazardous Waste Collection Day

Concord and Penacook residents can bring their unwanted household hazardous waste to the City of Concord’s Household Hazardous Waste Day for safe disposal. The event occurs once a year, so be sure subscribe to Notify Me to be notified of future collection dates.

Household Hazardous Waste Collection Day 
When: September 12, 2026
Where: Douglas N. Everett Arena (15 Loudon Road, Concord, NH)
Time: 9:00 a.m. to 3:00 p.m.

Concord residents can bring up to 10 gallons or 20 pounds of household hazardous waste. Proof of Concord or Penacook residency is required (driver's license, utility bill, etc.). Safely transport household hazardous waste in your car by leaving materials in their original containers, tightening lids, and packing items in sturdy boxes to avoid spills. Never mix chemicals or smoke while handling hazardous waste.

Help minimize hazardous waste by only buying what you would use. Seek alternative methods and products to reduce use of hazardous waste materials. Always read the product labels for information about proper disposal and special directions for storage. Excess materials should be carefully stored in a cool and dry location out of reach from children and animals. Product labels that read, “danger,” “poison,” “warning,” “flammable,” “reactive,” “corrosive,” “toxic,” or “caution” indicate that an item is a hazardous waste product. All household hazardous materials need to be carefully disposed of for public safety and to protect our environment.
