    s ensory > >>>I. segregate One of the best things you can do to keep your trash cans and rubbish bins from smelling like an open land ll is to segregate your garbage. If you keep all your household waste piled up in just one trash can, the odors will mingle and stink to high heavens. Plastic

    trash cans are cheap, and you can make trash cans and rubbish bins out of old cans and even woven baskets.

    You should have at least four trash cans outside your home, each for the following purposes:

    Waste paper, cardboard, and other paper products. You can store of ce paper, product packaging, and old les in this trashcan. You can take these products to a recycling center to be processed into recycled paper.

    Recyclable and non-biodegradable waste . Recycling facilities need your plastic bottles, aluminum cans, and other non-biode-gradable household waste items. You can even recycle old products on your own.

    Kitchen waste, leftover food, and other biodegradable waste. Rotting food, vegetable peelings, and other kitchen wasteshould not be mixed with other waste. You can put these waste products to good use by turning them to compost, and use the re-sulting product as fertilizer or mulch.

    Garbage. Whatever cant be recycled or composed can go in this can.

    II. Clean and Wash Many people forget that even trash cans need a good cleaning every now and then. Dirty trash cans are coated with a thick, dis-gusting, slimy ooze that has a very unappealing and nauseating odor. If you dont clean your trash cans, the slime will build up andadd to the funky odors that come from your garbage.

    As soon as you empty your trash can for the garbage collectors or out to the dumpster, give it a good hose-down with extrastrength soap and water. The task involves a lot of elbow grease, and its not the cleanest job in t he world, but its completely nec-essary. Do this every time you throw out the trash.

    It also helps to line your trash can with a thick garbage bag to prevent the slimy ooze from forming on the sides of the can. Makesure the bag does not leak, and that you dont dump anything wet into the bag.

    III. deodorize There are times that you have to put something really smelly and stinky into your trash can, like a soiled diaper or spoiled food. There are many things that you can do to keep the odor from stinking up your home. Here are someordinary household ingredients that you can use to deodorize your trash can:

    Baking soda. Plain old baking soda is a do-it-all wonder for your home. Its excellent at absorbing odors, whether its from refrigerators or freezers or even trash cans. If your trash c ans are made from plastic, you can simply put agenerous amount of baking soda inside the can and leave it there overnight. If your trash can is made of metal, youneed to put the baking soda inside a suitable container to prevent the chemical from corroding the material.

    Charcoal. Charcoal is an excellent deodorizer that has proven odor- ltering qualities. Charcoal is used in everything, from expensive cigarette lters to air purifying units. You dont need to buy activated charcoal; you can simplybuy a bag of charcoal, pulverize it a bit with a broomstick or a pick handle, and dump the charcoal into the trash canLet the charcoal sit overnight to remove the odors.

    Vanilla extract. The powerful scent of vanilla extract can mask the odor of stinky rubbish you throw into the t rashcan. Place a small amount of vanilla extract on a couple of cotton balls, and let them stay overnight in the trash can.Vanilla extract is expensive, so do not dump the precious liquid into the trash can.

    Citrus peels. The zest and pith of oranges, lemons, or limes are very effective at masking odors from trash cansand rubbish bins. Make sure that you use dry peels.

    Coffee grounds and tea leaves. Coffee grounds and tea leaves are used extensively by coffee shops to deodorizeash trays in smoking areas. You can leave some coffee grounds or tea bags overnight to remove and mask the foulodors from your trash can. Dont use instant coffee; as much as possible, use fresh coffee grounds.

    s ensory >>>>GARBAGE SMELLS. but anyone with a nose knows that garbage can stink. A bag of mor diapers left in a garbage can on a hot, humid summer day can send a powerful messagabout the mischief-making powers of bacteria and microbes.

    A bag of garbage smells for a very simple reason. It contains decaying, persuasible mateals such as meat or vegetables or diapers. As meat decays, it attracts bacteria that feaston the amino acids in the meats proteins. Vegetables also can rot and slowly liquefy asmicrobes attack the vegetables cell structure and the fermenting liquids warm up the gabage bag. As more gasses and liquids are produced, the bag may rupture. It may soundgross, but it is just garbage at work.

    Smell is a very direct sense. In order for you t o smell something, molecules from thatthing have to make it to your nose. Everything you smell, t herefore, is giving off molecu-- whether it is bread in the bakery, onions, perfume, a piece of fruit or whatever. Thosemolecules are generally light, volatile (easy to evaporate) chemicals that oat through theair into your nose.

    The sense of smell is associated with sensory receptor cells in the upper nasal cavity. Thsmell, or olfactory, receptors are chemoreceptors. Chemicals that st imulate olfactory re-ceptors enter the nasal cavity as airborne molecules called gases. They must dissolve inthe watery uids that surround the cilia of the olfactory receptor cells before they can bedetected. These specialized cells, the olfactory receptor neurons, are the only parts of thenervous system that are in direct contact with the outside environment. The odorous gasethen waft up to the olfactory cells, where the chemicals bind to the cilia that line the nascavity. That action initiates a nerve impulse being sent through the olfactory cell, into theolfactory nerve ber, to the olfactory bulb, and to the brain. The brain then knows what thechemical odors are.
