Polyethylene terephthalate (aka. PET, PETE, PETP) is a thermoplastic resin of the polyester family that is used to make beverage, food and other liquid containers, synthetic fibers, as well as for some other thermoforming applications. It is also one of the most important raw materials used in man-made fibers. Depending on its processing and thermal history, it may exist both as an amorphous (transparent) and as a semi-crystalline (opaque and white) material. It can be synthesized by a transesterification reaction between ethylene glycol and dimethyl terephthalate. It is manufactured under trade names Arnite, Impet and Rynite, Hostaphan, Melinex and Mylar films, and Dacron, Terylene & Trevira fibers

Yes biodegradable detergents are better for the environment

Plastic vs. Glass\nfirst off it isn't too fair to compare plastic to glass. You're comparing a category of materials against one single material. Plastics have almost an infinite range of properties where as glass has one set of properties. There are some plastics such, as acrylics, that behave very similarly as glass with respect to impact strength, clarity, etc. And there are some plastic that behave nothing like glass. Such as polyurethane, very ductile and rubbery even. \nTo conclude, depending on the plastic there can be many differences between plastic and glass, or they can be quite similar.

Well, lets see ... there's plastic, steel, and nylon for sure.  \n\nAnd possibly ...adhesives, polystyrene, paint, glass (this one's a little iffy because it does occur in nature, albeit infrequently)

Many plastics materials are microwave transparent, but some grades of Polypropylene have been refined specifically for use in microwave cooking applications.\n\nBP is a major supplier, I suggest you look there?

Non-biodegradeable means that when you throw something out, it does not fall apart on its own in nature (like a napkin or paper gets mushy and breaks apart when wet, or how food rots).\n\nThis is a problem because all this waste accumulates or builds up. Thus more and more space is needed to bury it. Alternatives to placing it in the ground is burning it, and this is bad because it releases chemicals into the air that can harm the environment and people.\n\nBest solution is to recycle plastic, that is people shred it or melt it and reuse it. Other uses are to take plastic bags and mix it with glue and wood and make a new type of wood that is very resistant to water damage. This type of wood is used alot now in lawn furniture and porches.

Vinyl chloride is polymerized to make polyvinyl chloride, also called PVC.\n\nPVC can be molded or extruded into just about any shape, including pipe.  It is a rigid plastic itself, but can be made flexible by the addition of plasticizers.  Plasticized PVC is often called simply: vinyl.\n\nPVC is a very durable plastic, although pure PVC can be degraded by UV exposure.  PVC for outdoor use (vinyl siding, vinyl windows) often contains other chemicals that prevent that degradation, either by absorbing the UV light or by preventing the subsequent chemical reaction.

To answer that question, another must be posed.....\n\nHow thin can you make copper wire?\n\nThe answer is yes, you can insulate copper wire with hemp plastic, as thin as a biodegradable plastic grocery bag\n\nHemp plastic is a cellulose based plastic.\nOnce you introduce it to the soil it will deteriorate, and once again become part of the earth. Hence Biodegradable

CHICKEN FEATHERS\nChicken feathers are now being sorted, processed and made into many useful products. Some you really don't want to think about. The processed fibers from chicken plumage have been used in plastics, in paper pulp and textiles. They can also be used to make a polymer film that is made into thin sheets of plastic similar to cellophane. This polymer may first show up in biodegradable candy wrappers and plastic holders for six packs of beverages. It may also be used in plastics for dog food bowls and automobile dashboards. And a process has even been developed to make the quill protein 90% digestible - possibly for use in dietary supplements. So you could soon be eating a chicken quill protein bar wrapped in biodegradable chicken feather plastic wrap. Mmmm, Mmmm good!\nCar Parts from Chickens, Diane Martindale - Scientific American, April, 2000.\n\nPoultry Feathers Made Into Plastic Mulch \nBy Sharon Durham, February 24, 2005\n\nAgricultural Research Service (ARS)* scientists who have developed a method to turn chicken feathers into plastic products are continuing to bring the technology closer to the marketplace. \n\nARS chemist Walter Schmidt developed the technology to clean feathers and separate them into chopped fibers and quill pieces. Now Schmidt and fellow ARS chemist Justin Barone have developed and applied for a patent for a process to convert cleaned and chopped feather material into plastic products on a laboratory scale. Schmidt and Barone work in ARS' Environmental Quality Laboratory in Beltsville, Md. \n\nAccording to Barone, the material is made on traditional plastics processing equipment using chopped chicken feathers and other easily obtainable, naturally derived materials. The feather-derived plastic can be molded just like any other plastic and has properties very similar to commodity plastics such as polyethylene and polypropylene. This makes the feather-derived plastic a unique material for packaging or any other application where high strength and biodegradability are desired. \n\nPrevious research by Schmidt and Barone found feather fiber could be added into currently used plastics to make composites. The fibers strengthen the plastic components, and reduce the weight of the material. Currently, the additives and fillers used in plastics by the automobile industry, for example, add significant weight to car parts. Using feather fiber is a viable alternative to these additives. \n\nApproximately four billion pounds of feathers are generated each year during the poultry production process, resulting in a serious solid agricultural waste problem. This new application not only is a solution to an environmental problem, but also cost-effectively enhances the commercial and economic value of feathers.

Polymers from some plastics can supposedly leach.\nThis happens e.g. if you microwave something without removing the saran wrap.\n\nIn general the environmental hazard with plastics and polystyrene is not that they're toxic, but that they will last for thousands of years. It's unfortunately more economical to make them disposable than to recycle. If oil hit $200 a barrel or there were higher pollution fines /landfill fees this would change.

Plastic recyling is very difficult because different types of plastic are not miscible with each other.  For this reason, plastic is typically recyled by cutting it into small pieces and then molding it with a binding agent into blocks.  These are then used to replace wood in items like park benches.

Rubber comes from a tree and plastic comes from oil. Therefore rubber is "natural" and plastic is not.
