Biodegradable means it can be decomposed but it needs a chemical agent to help break it down . Whereas degradable means it can be chemically degraded and it does not need an agent to degrade it.
All material that we have no further use for can be called waste,this can be differentiated into two categories,biodegradable & non biodegradable/The first is all material like,paper,garden waste & lawn clippimgs,non greasy food, cloth scraps,wood shavings,material from cleaning up pet cages etc,these can be broken down by insects worms & other soil organisms into humus which can safely be part of the soil,composting is a good example of converting biodegradables into a useful end product.Non biodegradables reguire recycling depending on the material.The important lesson is the concept that we are responsible for the safe & sensible disposal of items we no longer have use for disposing items
Biodegradable things break down over time. Non biodegradable items sit in dumps and landfills for a long time because they do not break down.
It means the substance or liquid can break down in the water or earth without polluting the earth.
Biodegradable things slowly degrade over time and do not harm the earth. Something that disentagrates will fall apart or "rip" apart and do ot nessacarily harm or not harm the earth.
biodegradable pollutants can be broken down by living organsims where as non-biodegradable cannot be broken down back into the soil
the bio degradable wastes are those which can be decomposed in the soil and non biodegradable are those which cannot be decomposed in the environment
Biodegradable pollutants eventually break down and become part of the environment again. Nonbiodegradable pollutants never become a natural part of the ecosystem again.
Nothing.
Biodegradable can be broken down by the earth naturally, non- biodegradable can not.
Primary pollutants are pollutants that enters the air directly from a source and Secondary pollutants are air pollutantsproduced by the reaction of a primary pollutant with some other pollutant
Some Primary pollutants are like when humans directly put them in the air Secondary pollutants are like when pollutants react with Primary and other Primary pollutants.
Biodegradable means that something is capable of being decomposed by bacteria or other living organisms. A paper wrapper for a sandwich is biodegradable, but a plastic box is not. Bury the plastic box, dig it up a year later, it is still there. The paper wrapper would have degraded to humus (soil).
Material that's nonliving (excluding dead organic matter) is non-biodegradable. Plastic, metal, styrofoam, and corrugated cardboard are non-biodegradable, while a dead tree, animal waste, and skin cells are biodegradable. A difference between biodegradable trash and non-biodegradable trash is that the biodegradable can be thrown out into a backyard and eventually turn into soil or something that other living things can reuse, while non-biodegradable trash can be recycled, as in reused for its original purposed, usually for humans.
Dioxin's are pollutants formed when waste is not incinerated at high enough temperatures. A Dachshund is a dog.
In general organic compounds / substances / materials contain carbon atoms bonded with other atoms and/or those related to life. It is the chemistry of carbon containing compounds. Inorganic is everything else and generally do not contain carbon (with some exceptions).
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...

When something is bio degradable it will break down in the environment with the assistance of bacteria or other organisms. Non bio degradable detergent will not break down naturally without chemical assistance.
The difference is that biodegradable means that items such as food waste, garden waste and certain plastics can be broken down by the actions of bacterium, fungi and other living organisms. They can be composted. Recycled means that they can be reused as they are once cleaned, processed or treated eg clothes, paper, card and glass.
All Plastics are the polymers but all the polymers are not the Plastics, why because there will be biodegradable polymers, biopolymer, rubber exist, which will be not in the plastic group
