Setiap hari kita membuang pelbagai jenis sampah, tidak kira di rumah, di sekolah, di tempat kerja, di tempat awam, atau di mana-mana saja selagi kita hidup yang mana memerlukan makanan, minuman, pakaian, dsb. Bekas atau bahan yang telah digunakan atau tidak boleh digunakan lagi, akhirnya akan menjadi sampah. Bayangkan apa yang akan terjadi jika seminggu lori sampah pihak berkuasa tempatan mogok dan tidak mahu mengutip sampah di taman-taman perumahan? Tentulah kawasan tersebut dipenuhi lalat dengan bau yang busuk dan mengganggu kesihatan penduduk setempat.

Kebanyakan kita membuang sampah atau bahan buangan dari rumah tanpa mengetahui bahan yang dibuang itu berbahaya kepada umum atau tidak? patutkah bahan-bahan buangan tersebut diasing-asingkan terlebih dahulu sebelum dibuang ke dalam tong sampah? Semua ini memerlukan pengetahuan asas dan kesedaran siviks supaya bahan-bahan yang dibuang tidak membawa kemudharatan kepada diri sendiri dan orang lain di sekelilingnya.

Oleh itu, pengetahuan asas tentang pembuangan secara selamat bahan-bahan terpakai atau bahan buangan dari rumah perlulah diwar-warkan kepada orang awam. Semoga ini dapat mengelakkan kemalangan atau kejadian-kejadian yang tidak diingini, seperti kebakaran, letupan, dan lain-lain, yang boleh mengancam nyawa.

Panduan untuk membuang bahan terpakai atau bahan buangan dari rumah dipanjangkan di bawah ini untuk manfaat semua….

Disposing of household nasties – safely

Wondering what to do with all those chemical nasties lurking in your cupboards? Here’s how to dispose of them safely.

Next time you have a big clean-up, stop and consider what happens to all those old medicines, pesticides, pool chemicals, cleaners, paint thinners and batteries after you’ve thrown them in the bin or down the sink, or hosed them down the gutter.

Some chemicals become more dangerous when mixed with other chemicals, food scraps or even just water. Some things are hazardous because they contain heavy metals and other poisons that contaminate soil and pollute waterways.

Flammable chemicals and sharp objects pose a serious risk to others — such as waste collectors and handlers, children and curious animals — when they’re sitting in your garbage bin and going into the garbage truck.

Clearly you don’t want all these nasties sitting around your house either, endangering the health and safety of you and your family. So what do you do with them?

The following are some health and environmental hazards associated with products commonly found in the home, and options for their safe disposal.

Paint and related products

Paints, thinners, varnish, wood stain, solvents, methylated spirits, turps, glues and fillers.

The problems:

* They can be highly flammable.
* They can give off toxic fumes when they evaporate or burn.
* They can be toxic to plant, animal and aquatic life, as well as people.
* Aerosol cans are potentially explosive if heated or punctured.
* Oil-based paints contain flammable solvents, and brushes have to be cleaned with turps, another disposal problem.

The solutions:

* Use water-based paints rather than oil-based whenever possible.

* Calculate the area to be painted, and buy the smallest tin of paint that will meet your needs.

* Never pour these products down the sink or an outside drain.

* Use up the products, or give them to friends or neighbours who can use them. There may be a paint collection centre near you for community projects.

* Old paint that has hardened can be thrown out with your normal garbage. Leave the lid off the tin if there isn’t much left (preferably outside, so the fumes don’t cause harm), or pour it over newspaper, let it dry, then throw it away.

* If none of these options is practical, phone your local council for advice.

Medical waste

Medicines, needles and syringes (including veterinary products).

The problems:

* If left around the house, expired or left-over medicines pose a safety risk, particularly to children or people with poor eyesight.

* If you dispose of them in your household garbage, children or animals could be poisoned.

* Putting medicines down the toilet or sink can affect sewage treatment (which depends on bacteria and other organisms to break down waste).

* Used needles and syringes pose a health and safety risk to waste handlers, children and curious animals.

The solutions:

* Don’t put bottles containing pills or liquid medicines in your garbage.

* Take unwanted pills out of their packaging, and wrap them in newspaper. Soak the newspaper thoroughly to dissolve and dilute the pills, put it in a plastic bag and then dispose of it with your normal garbage.

* For liquid medicines, if there’s only a small amount left, pour it onto several layers of absorbent paper, wrap securely in a plastic bag and put it in your garbage bin.

Household cleaning products

Ammonia, chlorine bleach, disinfectant, dry cleaning fluid, drain cleaners, polish and oven cleaners.

The problems:

* Some cleaners give off dangerous (and potentially lethal) fumes when mixed — some toilet cleaners with bleach, for example.

* If you tip large quantities down the sink or toilet, they can interfere with the bacteria which break down waste in the sewage treatment process.

The solutions:

* Never put them down the sink or drain. (Some will obviously go down the sink while you’re cleaning, but in small quantities they won’t do a great deal of harm. However, heavy use can kill bacteria in the sewerage system and may harm human health and the environment.)

* Use up the products, or give them to friends or neighbours who can use them.

* Use less hazardous alternatives where possible.


The problems:

* The cadmium in nickel cadmium rechargeable batteries (NiCads) is a highly toxic heavy metal.

* Car batteries contain lead and highly corrosive acid.

The solutions:

* Nickel metal hydride rechargeable batteries (NiMHs) don’t contain toxic material and can be disposed of with your household waste.

* Using rechargeable batteries will mean fewer batteries going to landfill.

* Never burn batteries — this releases dangerous fumes and can cause an explosion.

* For your old car battery, check with your local garage or car battery retailer — they might take it from you. When you’re transporting one, handle it very carefully and make sure the acid doesn’t leak out.

Fuels, oils and other flammables

The problems:

* Fuels are highly flammable and dangerous to store around the home. If you don’t need it, don’t keep it.

* Used motor oil contains a number of toxic chemicals, and may contain lead.

* Oil and water don’t mix: don’t put motor or cooking oil into the sewerage or stormwater system.

The solutions:

* Used motor oil can be recycled Ñ your local garage or tip might take it. (Ask your mechanic, at your next grease and oil change, if they recycle motor oil.)

* Collect used cooking oil in a sturdy plastic bottle and throw it out with your regular garbage.

In Brief

* Think before you throw it out Ñ does the product pose a danger to people, pets and other animals, or the environment?

* The best way to avoid future problems of disposing of dangerous products is to buy and use non-hazardous alternatives wherever possible. And only buy what you really need, in the quantity you need.

Do’s and don’ts


* Use non-hazardous alternatives wherever possible.

* When you have a choice of pack sizes, buy only as much as you need.

* Give left-over chemicals to someone who can use them.

* Store chemicals carefully in a dry, well-ventilated area, safely locked away from children and pets.

* Leave products in their original containers, and write the purchase date on the label.

* If you’re taking chemicals to a hazardous waste depot, make sure they’re packed securely and labelled clearly.


* Store chemicals in food or drink containers.

* Tip hazardous chemicals down the sink or toilet — a sewage treatment plant can’t break down all toxic substances, and they could create potentially explosive fumes at the plant. Some chemicals interfere with the biological processes used in breaking down sewage.

* Put hazardous chemicals (including motor oil) down the drain or hose them into the gutter — they’ll go directly into your local waterways.

* Bury them — they can poison local plants and wildlife, contaminate soil and leach into the groundwater system.

* Unless stated otherwise in this article, don’t throw them in the garbage bin. Seemingly harmless on their own, chemicals can react with other substances, possibly creating dangerous fumes, and even a fire or explosion in the garbage truck or waste centre. In landfill, they can leach into the soil and the groundwater system.

    • That’s why we should make them and the public aware of the hazardous effects of these rechargeable batteries to our environment and our lives….
