Missoula facility outlines hazardous waste disposal guidelines for common household products

The City of Missoula is taking significant steps to educate residents about the safe disposal of household chemicals through its Home Resource Zero Waste Lunch & Learn Series. During the latest session, held on June 9, 2025, community members learned about the various types of hazardous materials that can be disposed of at the local facility, as well as the importance of proper disposal methods to protect both public health and the environment.

One of the key topics discussed was the disposal of flammable materials, which include common household items such as old gasoline, paint thinner, and oil-based paints. Residents were informed that while oil-based paints are accepted, latex and acrylic paints should be dried out with materials like kitty litter before disposal. This distinction is crucial, as improper disposal can lead to environmental contamination.

The session also highlighted the challenges associated with aerosol spray cans, which are limited to five per household due to space constraints at the disposal facility. The costs associated with disposing of these materials were explained, as they must be transported to a high-intensity incinerator in Salt Lake City, making the process both expensive and complex.

Participants learned about the dangers of chlorinated solvents, such as perchloroethylene, which have been banned in Missoula for over 20 years due to their carcinogenic properties. However, these products can still be purchased outside the county, raising concerns about their safe disposal.

Additionally, the discussion covered the disposal of pesticides, herbicides, and corrosive substances like bleach and ammonia. Residents were encouraged to bring these hazardous materials to the facility to prevent them from entering the waste stream and potentially harming the environment.

The meeting underscored the importance of reducing the use of hazardous materials in the first place, promoting safer alternatives and practices. As Missoula continues to prioritize environmental health, these educational initiatives play a vital role in empowering residents to make informed decisions about chemical disposal.

In conclusion, the Home Resource Zero Waste Lunch & Learn Series is not only providing essential information on hazardous waste disposal but also fostering a community commitment to sustainability and safety. Residents are encouraged to participate in future sessions to further their understanding and contribute to a healthier environment.
