Climbing out of the ozone hole. A preliminary survey of alternatives to ozone-depleting chemicals.

Type of article: Periodical article

Summary

The document gives the latest data on the ozone hole and on the causes of its current and future widening. Drastic measures are presented and the substitution means are described with precise examples. All categories of CFC users are described: refrigeration industry, solvents, aerosols, fire protection and foams. Environmental protection is the absolute priority, and thus it seems necessary to re-use past technologies and old customs: 1) utilization of ammonia, water and CO2 as refrigerants and helium for the Stirling cycle; 2) utilization of insulants which preceded foams (glass wool, cork, etc.).
