Because metals are still so cheap to produce, and have such good mechanical properties that they remain the most viable choice for most bikes.
Companies that make high temperature plastics are: Profressional Plastic, Zuesinc, Acetate. They are great companies that make all kinds of plastics for your needs.
The word "plastic" is an old word meaning something along the lines of "moldable". Many materials commonly called plastics are moldable, at least if you heat them up (not all of them, though; it always gives me a little twinge to hear someone call a material like Bakelite "plastic" ... it will burn before it softens or melts).
Some plastics..think about car head lights, or the microwavable plates and cups, baby bottles, all those can with stand high temps. Now ones that can't are like grocery bags, water bottle, thin plastics.

1% or less of all oil consumption goes toward making plastics, so it is a sustainable source. However, we also consume oil as fuel, and THAT is where oil becomes an unsustainable source. If we can move away from oil as a fuel, then oil becomes sustainable.

No, not all plastics are petrochemicals. A few examples of bioplastics (plastics made from biologic sources) include Polyhydroxyalkanoates, Polylactic Acids and a wider variety of starch based plastics.
All plastics are products of the chemical industry.
4 are on tricycles and 6 are on bicycles
yes
Polymers are large molecules made up of repeating units, while plastics are a type of polymer that can be molded into various shapes. Not all polymers are plastics, but all plastics are polymers. Plastics are a subset of polymers that have additional properties, such as being lightweight, durable, and easily molded.
THere is small-scale bicycle production all over the world, but most bicycles are built in Asia.
Diamondback Bicycles is a company out of Kent, Washington that specializes in Chinese made bicycles of all kinds. They offer many models of mountain bikes, but also offer bicycles for pavement and BMX as well as a full line of children's bikes and exercise bikes.
Plants don't make plastic. Petroleum is the basis for plastics, pvc, and all other types of plastics. Rubber however was originally derived from the Rubber Plant - Ficus elastica
A. About 80 percent of all municipal solid waste is landfilled, while 10 percent is incinerated and 10 percent recycled. Because only a small percentage of plastics is recycled (less than one percent), virtually all plastics are landfilled or incinerated.
All!
They are all human powered.
