Freon is a registered trademark of DuPont. It is their line of HCFC refrigerant products. It is still used today in many refrigeration systems. However, production phaseout of this product will reduce and eventually eliminate the production of HCFC products. By that time most or all Freon refrigeration systems will most likely be replaced or retrofitted by non-HCFC products.

Yes, Freon R11 was used widely in the past but is no longer sold because of the damage it causes the ozone layer by release of CFC's.
Refrigerant units still require Freon to operate efficiently but it has been modified somehow that I don't know about, to enable it to be used safely.
The cost has been in that the old R11 fridge units cannot run with the new specification Freons such as R22.
Having experienced the operation of both R11 and R22 Industrial refridgeration units I am in no doubt that the R11 charged were the better units.

Many older fridges are still run on Freon but, it is no longer used in new models.
Following is a guideline for disposal.
Materials NOT accepted at the Waste Disposal Site are:
*..Items containing freon (fridges, air conditioners, freezers, dehumidifiers, etc.) unless freon has been removed by a licensed technician and a sticker is placed upon the item.
*..Oil based paint, varnish, etc. (only latex paint is accepted, but it must be completely dry)
*..Hazardous wastes (such as paint thinner, aerosol cans, drain cleaners, pesticides, propane tanks, household cleaning supplies, etc.)
*..Electronics (computers, televisions, etc.)
*..Flouresent light ballasts
*..Methyl hydrate, radiator coolant, antifreeze, etc.

R134a is the most efficient of the current non CFC ones available

Its illegal now because it can deplete our earth ozone layer. But i doubt if all is following this law.

It is not allowed by law now because of the fluorocarbons
