Some people take their vehicles to a mechanic for maintenance and detailing, while others prefer to do the work themselves. If you handle car care at home, remember to dispose of hazardous waste properly and safely. Items like used oil, old filters, and empty chemical bottles may not look harmful, but when thrown out improperly, they can be swept into storm drains or leach chemicals when it rains, contaminating our waterways and damaging our environment.
Here are some common types of auto materials, how to dispose of them safely, and why proper disposal matters.
- Motor Oil
- What to do: Never dump used motor oil in the trash, down the drain, or anywhere outside. You can safely dispose of used motor oil in the trash by pouring the liquid into a plastic bag filled with absorbent material such as shredded newspaper, old rags, or sawdust. Once all the oil is absorbed, seal the bag and throw it away. A commercially available oil change box works the same way. You can also reuse empty motor oil bottles in place of the plastic bag. Just make sure to seal it well to prevent leaks!
- Why it matters: Even a small amount of oil can pollute a large volume of water. Proper disposal keeps it out of the environment.
- Car Batteries
- What to do: Shops are required to take your old battery when you buy a new one. You can also bring used batteries to any City drop-off convenience center or transfer station.
- Why it matters: Batteries contain lead and acid, two things that donʻt belong in landfills or waterways.
- Old Tires
- What to do: Dealers must accept and recycle your old tires when you purchase new ones. You can also drop them off at City convenience centers or the Kapaʻa and Kawailoa Transfer Stations.
- Why it matters: Tires take years to break down. Recycling gives them new life as playground surfaces, construction materials, and other products.
Properly disposing of auto care materials takes little extra time and makes a big difference. It keeps harmful chemicals out of Hawaiʻi’s environment and helps reduce waste through recycling.
