Although Haz Waste Days provides a way to safely and responsibly dispose of household hazardous waste, there is no perfect way to dispose of it. The manufacture and disposal of hazardous waste impacts the environment and public health, and the best way to reduce its impact is to create less of the product. People can reduce household hazardous waste by following these tips:

  • Buy only what you need and use it up. Disposing of toxic products often costs more than buying them in the first place; stocking up on hazardous products is not a good idea.
  • Give your usable leftovers to someone who can use them safely.
  • Always use the least-toxic product available. Whenever possible, use latex or water-based paints and stains, which are less toxic than oil-based products. Missoula County Weed and Extension has information on less toxic alternatives for lawns and gardens. Call the Plant Clinic at 406-258-4213 or visit for more information.

Local health and fire agencies also urge people to clear out unneeded flammable liquids, such as oil-based paints, paint thinners, fuels, waste oil and solvents. These flammable products can be easily ignited and quickly accelerate a fire. They also pose a threat to the health of firefighters and neighbors when they are burned.
