Automobiles generate tremendous amounts of hazardous waste. Two of the most common are used oil and antifreeze. If you are a mechanic who generates significant amounts of this waste, you need professional disposal. Master Environmental has been serving the Boise community for over 30 and is pleased to offer our disposal services to you. Please contact us today to find out what we can do for you.


Each year, Idaho residents throw away countless gallons of used oil. Many of the people improperly disposing of this oil are people who changed the oil in their cars. Unfortunately, used oil is dangerous and can easily work its way to drinking water. Oil dumped down drains, storm sewers, or in the garbage can seep down to groundwater or get washed into waterways, where it can poison wildlife and ultimately humans.

And when humans come into contact with used oil, the results are deadly. Many illnesses have been linked to contact with used oil that compromises the health and safety of our communities, such as:

  • Fetal abnormalities
  • Various cancers (lung, liver, kidney, bladder, and skin)
  • Death

Used oil is also lethal to plants and animals, which can also die from unnecessary contact. For these reasons, used oil must be disposed of in a proper manner.

There is simply no need for this waste. Used oil actually has many uses, such as:

  • Used oil can be turned into heating oil for homes.
  • Used oil can be re-refined so that is reusable.

Re-refining used oil is energy efficient and could save Idaho millions of dollars, so do your part and hire an environmental disposal company to dispose of your used oil properly.


Antifreeze is a chemical substance that lowers the freezing point of solvents such as water. Antifreeze is a popular coolant in internal-combustion engines because it allows the water to go below 32 degrees Fahrenheit without freezing. As a result, the engine can cool much more rapidly without risk of damage.

Common antifreeze substances are:

  • Ethylene glycol
  • Methanol
  • Ethanol
  • Propylene glycol
  • Isopropyl alcohol

Unfortunately, waste antifreeze is highly dangerous and contains heavy metals (like lead) which qualify it for regulation as a hazardous waste. If you need to dispose of antifreeze here in Boise, you should contact a professional disposal company like Master Environmental to make sure you properly dispose of it.

Because antifreeze is so dangerous, remember to wipe up any spills. You also should not dump excess or waste antifreeze down a drain, ditch, or well, since it can harm wildlife and the environment. Also remember to keep waste antifreeze in a properly labeled container so that you do not confuse it with antifreeze that has not yet been used.

I contacted Gary about an underground oil tank I discovered. He was very responsive and after a brief visit to the... site, determined that his services weren't needed. Even so, he loosened some pipes for me with his pipe wrench so they could be easily removed at a later date, and didn't charge me a thing. Although I wasn't able to use him on this project, I would highly recommend Gary and Master more
