In 1978, CFCs were banned for use as propellants in nearly all consumer aerosol products. They are gradually being phased out in all products and manufacturing processes. If a product doesn't contain any CFCs, it doesn't necessarily mean it is safe for the entire atmosphere. Alcohols, butane, propane and isobutane are common VOCs. Emissions from cars and factories are the major source of VOC releases to the environment, but household cleaning products, floor polishes, charcoal lighter fluid, windshield wiper fluid, and hair styling spray, gel or mousse, whether in aerosol cans or spray pumps, also may contain these substances and contribute to smog problems.
Symbols Can Be Useful.
Since some communities don't accept for recycling every product or package that bears the symbol, it's a good idea to check with your local recycling or solid waste officials if you are unsure about appropriate disposal. SPI Symbol Manufacturers use this symbol, a code developed by the Society of the Plastics Industry, to indicate the type of plastic from which a particular product is made. SPI code numbers range from 1 to 7. Bottles or jugs labeled with numbers 1 and 2, such as soda bottles, detergent, shampoo, and milk jugs, are the most likely to be accepted for recycling.
