Biodegradable waste is more useful because it degrades. It breaks down into nutrients and organic material that is useful, like compost.
It is necessary to classify. This gives us an estimate where to dump each material.
Biodegradable products have the only real advantage because they break down and cause no threat to the environment. Non-Biodegradable products do not break down and take up space in landfills for many years. Non-Biodegradable products tend to be cheaper to make though.
One can find biodegradable plastic bags in store at Sainsburys, Tesco, Asda, Morrisons, Wilkinsons, Boots, Marks & Spencer and many more UK based supermarkets.
they are more useful because they have more copper inside .
The main difference between Ordinary Polythene & Biodegradable polythene is: * Ordinary polythene takes an around 100 + years to degrade... * Biodegradable/Degradable polythene degrades or biodegrades in around 5 yrs depending on how it's made and how its disposed. However, biodegradation starts in the presence of sunlight, moisture, mechanical stress and/or microorganisms... For more information on biodegradable polythene film please visit www.polybags.co.uk who offers both type of bags and will be able help you more... http://www.polybags.co.uk/index_scroll.htm?main=cs_898.htm.
infrasound is more useful than sound for detecting volcanic eruptions because it traves a lot further than sound and is hear km away
there will be more and more polloution
There are many kinds of waste, and many ways of disposing of waste. Most communities have sewage treatment plants, which treat sewage waste. Improvements in how this is done are coming rapidly. Industrial waste might or might not be biodegradable. For example inorganic chemicals are not normally biodegradable. On the other hand, leather scraps and wood chips are. Some non-biodegradable waste is put into landfills, and some is recycled for reuse. Biodegradable industrial waste may be digested in special reaction vessels. Farm wastes may be similarly treated. Hazardous waste is specially treated, as required. Nuclear waste is left in casks at the plants that created it, until someone makes a decision about what to do with it. Household waste is often segregated, as required by municipalities. Plastics and metals, which are not biodegradable, are recycled. Hazardous waste goes into special containers, often on designated days. Biodegradable waste is often composted, either by the municipality, or by the resident. Biodegradable waste can give off methane gas as it decomposes. Methane is a powerful global warming gas, much more powerful than carbon dioxide. In places where a sufficient amount of methane is generated, it is often used to generate heat or electricity. In other words, the answer is Yes.
Non-biodegradable waste has a very harmful effect on the environment. Non-biodegradable products take many years to decompose, and cause more and more land to be used for landfills. Toxins from plastics leach into ground water causing contamination.
It should be noted that conventional plastics can be made biodegradable with the inclusion of a small amount of an additive that promotes biodegradation. It is then called oxo-biodegradable plastic. Read more at http://biogreenproducts.com . Many plastic disposable products are being introduced that can be biodegraded using oxo-biodegradable technology.
Biodegradable substances are waste substanses that can decompose after a peirod if time whether short or long e.g basically food, paper, etc While non biodegradable substances are waste products that can not decompose even after a long period of time e.g glass, metal cans, cups, plastic and the have to be recycled.
by adding chicken dung,pigs "popo" or any biodegradable waste!

Wastes that doesn't decay or can't be decomposed naturally, more precisely biologically.
Best way would be to separate the biodegradable waste from non biodegradable waste. If u want it to be more systematic, get in touch wid local authorities & set up an effiecient waste disposal system.
BIODEGRADABLE: The waste that breaks down easily by the action of some micro-organism (i.e. bacteria) and also can break down in a non-poisonous form. Biodegradable waste will eventually break down and become part of the earth and soil, like food scraps and paper. Non-biodegradable waste will NOT break down (or won't for many many years). Examples are plastics, metal and glass. Some dangerous chemicals and toxins are also non-biodegradable, as are plastic grocery bags, Styrofoam (polystyrene), and other similar materials. Non-biodegradable can be misleading, as often the subject that this term is associated with is organic matter and organic matter always decays so it is biodegradable. This term was principally created to help improve public awareness of responsible recycling. Plastic is classed as non-biodegradable but certain types of plastic decay at faster rates than others: a plastic milk bottle container purchased from a supermarket may take anything from 5 to 20 years in the environment to become brittle enough to be destroyed by the elements. Other types of thicker plastic may take 100-500 years or more to fully decay but in the timespan of the history of the world that is just a blink of the eye.
What I think about the trees is that, they shed their over-grown and no-more useful leaves in the season of Autumn. This is how I think that trees get rid of their waste.
Paper is a hundred percent biodegradable. Plastic is not biodegradable. We should use easily biodegradable materials more often, such as paper, wood, cloth, and the like.
