Household Hazardous Waste
Waste Prevention Tips
Hazardous Products and Guidelines
Some of the products you use at home are potentially
hazardous. Safe handling and proper disposal of these materials
will protect you, your family and our environment.
This section provides instructions for proper disposal
of your household hazardous waste products and tips for
minimizing their use in the future. The Waste Prevention
Tips is probably the most helpful and valuable section.
You can avoid having to dispose of hazardous products if
you buy only what you need and use it all, and whenever
possible, use nonhazardous alternative products.
Waste Prevention Tips
The best way to handle household hazardous waste is to
prevent it in the first place. By learning more about which
types of products are hazardous and about ways to use less,
use it up and use nonhazardous alternatives, you can significantly
reduce the generation of this type of waste right at the
Before you buy a product, read the label and make
sure it will do what you want.
Once you buy something, you are also responsible for disposing
of it properly.
Buy only what you need, and use it all up.
Be conservative in selecting the product container size.
A large container is not a bargain if you don't use it all.
Give away unwanted leftover products.
Ask friends, neighbors or non-profit groups if they
can use the products.
Look for nonhazardous alternatives.
Safer substitutes, like vinegar, lemon juice, baking
soda, salt, borax, olive oil and cedar chips, used alone
or in various combinations can get the job done as well
as their more hazardous counterparts. Consider the following
suggestions for nonhazardous alternatives:
- To keep drains clear and fresh smelling, mix and apply
1/4-cup baking soda and 1/2-cup vinegar. Let stand in
drain for 5-10 minutes. Flush with hot water.
- Windows can be cleaned with a mixture of 2 cups each
of vinegar and water and 2 tablespoons of lemon juice.
Use newspaper for a lint-free finish.
- An ice cube can be used to harden chewing gum before
scraping it from carpet.
- For a rug deodorizer, mix 2 parts cornmeal to l part
borax. Sprinkle over rug and leave for l hour, then vacuum.
- To polish furniture, combine 2 parts olive oil to 1
part lemon juice.
- Processed manure or fish emulsion is a good substitute
for chemical fertilizers.
- Mulch and compost are great soil enrichment products.
You can purchase them locally, or you can make it yourself
from your yard trimmings.
- Select water-based latex and non-toxic paint products
over oil-based paints and varnishes.
- Instead of mothballs, use cedar chips or dried lavender.
- Instead of bug sprays, use baited traps.
- Use glue or spring traps instead of rodent poison.
- Clean copper pots and stainless steel with salt and
- Clean stains from coffee cups and dishes with baking
soda and vinegar.
- To clean, disinfect and deodorize, use a mixture of
1/2-cup borax and 1 gallon

can be conveniently and safely

Flush down drain: Flush down the
drain with plenty of water; rinse and throw empty container
away in trash container.
|There is no reason to leave batteries
on the roadside or let them pile up in your carport.
Retailers are required to take your old battery when
you purchase a new one and recycle it. Many retailers
will take them without a sale. Or you can drop-off
old batteries at City Drop-off Convenience Centers.
Sprays: Place absorbent material
in a plastic bag, spray until can is empty, being careful
not to inhale the fumes; leave can in bag, then tie and
throw bag away in trash container.
Trash can: Close container
securely to prevent spillage, then throw away. Wrap light bulbs in newspaper before disposal.
Drop off: Take to a Drop-off
Convenience Center. Propane tanks may be empty,
or fully/partially full. Or you can take tanks (empty
or containing gas) to Air
(fee). Call Air Liquide at 842-4125 (Kalihi) or 682-2100
(Campbell Industrial Park).
Absorb and trash: Pour liquid
into a plastic bag with absorbent material, such as shredded
newspaper, old rags, or sawdust. Once liquid is absorbed,
seal the bag, then throw away in trash can. An oil change
box provides the same results. Paints can be hardened in
the can, then thrown away.
Return to retailer: Retailers
of auto batteries are required by law to accept your old
battery when you purchase a new replacement. For excess
auto batteries, call a battery recycler or ask retailers if they'll
accept additional batteries.
