Here's a taster:

Economical problems:
· Prices of bulk and specialty polymers
reflect the degree of chemical processing
and treatment needed to make them.
· Polymers which require more complex
treatment, such as ABS, PET and
polyester thermosets are generally more
expensive.…read more

Possible Solutions:
Recycling
· The reason people recycle is because some
plastics are non-biodegradable therefore the
only other option is to re-use them.
Mechanical recycling: Chemical recycling:
· Melting · Breakdown of the waste plastic
· Not very effective into monomer units
· Expensive · Thermal cracking and
gasification
· Requires lots of energy…read more
