what type of awareness should be created to protect the ozone layer
Answers
Answer:
There has been considerable progress in finding non-ozone-depleting substitutes for ODS in the last few years. Substitutes for air-conditioning and refrigeration applications are now available, such as that HCFC-22 can be replaced by HFC-410A, CFC-12 can be replaced by HFC-134a. There are also emerging markets for "drop-in" replacement for HCFCs and halons.
Alternative products or processes can be used in some cases including the following:
alternative insulating materials;
substitute food containers such as hydrocarbon blown polystyrene, plastic film wrap and bags;
alternative packaging materials such as plastic film bubble wraps; and
air-conditioning and refrigeration plants operating on non-HCFC refrigerants.
HCFCs solvents can be substituted in some applications. For instance, petroleum solvents can be selected as a replacement for CFC-113 or 1,1,1-trichloroethane in cleaning applications. Aqueous cleaning, or even no-clean technology, are also alternative processes that can be used by the electronics industry.
Many household and personal aerosol products, e.g. paint sprays and insecticides, now use hydrocarbons (e.g. propane and butane) as propellants instead of HCFCs or CFCs.
