Producing HFCs Meeting Societal Needs With Environmental Stewardship
A Worldwide Perspective
The 1989 Montreal Protocol ratification and its mandated CFC
and HCFC phaseouts posed a daunting challenge to
fluorocarbon producers. The aggressive phaseout timetables
presupposed that safe, cost effective and environmentally
acceptable alternative products could be rapidly developed
and manufactured. New product development and
commercialization --- from product formulation and plant
construction to toxicology and environmental impact
screening --- had to be competed in incredibly short time
frames to avoid significant societal disruption.
Industry responded with unprecedented creativity and
innovation. Individual fluorocarbon producers rapidly
increased resources --- people, time and money ---- toward
alternative product development and commercialization.
Industry partnerships under the Programme for Alternative
Fluorocarbon Toxicity Testing (PAFT), allowed resource
pooling to screen likely candidates. Potential
environmental impacts were studied through the Alternative
Fluorocarbon Environmental Acceptability Study (AFEAS)
group.
Industry's huge undertaking resulted in a comprehensive line
of safe, non ozone-depleting, high performance, cost
effective compounds that are in widespread use around the
world today --- HFCs. These compounds were extensively
studied before their introduction, with over $41,000,000
spent in PAFT & AFEAS studies alone.
High Value Products for High Value Uses
The unique properties and performance of CFCs, and the lack
of understanding and consensus about their environmental
impact led to widespread use. With the CFC and HCFC
phaseouts, HFCs and other options are being considered as
replacement products. HFCs enjoy widespread use because of
their overall effectiveness and attractive properties.
However, non-fluorocarbon alternatives are also being used
in applications such as refrigerants, propellants, foam
expansion agents, and solvents, presenting different options
and tradeoffs in terms of cost effectiveness, safety and
energy efficiency. All alternatives require chemical
processing, whether hydrocarbons, ammonia, CO2 or HFCs.
HFCs offer the highest overall value in many applications.
Producers advocate an approach of "responsible use"
predicated on the concepts of highest-value applications,
safety, total environmental impact, emissions
reduction/control, energy efficiency, and total system cost.
This ensures that both industry and consumers have options,
societal needs are met, innovation is encouraged, and
environmental impact is minimized.
Cleaner, More Advanced Manufacturing
HFC production requires longer, more complex processes and
more sophisticated technology than the simple CFC
manufacturing processes. Many products, such as propellants
used to deliver drugs for the treatment and control of
asthma, or refrigerants, must meet stringent quality and
purity standards. Producers have developed and installed
new, more efficient systems to minimize
operational and process emissions. Modern HFC plants have
sealed systems and closed loop transfers for both internal
transfers and for loading and delivery of bulk customer
shipments. HFC process leaks are limited to about 0.1% of
total production, resulting in negligible environmental
impact from handling.
Worldwide, industry has invested well over $40 billion to
replace ozone-depleting CFCs with safe, effective, high
performance HFCs.
Industry Principles for Product Stewardship
Fluorocarbon producers are stewards for the products they
make and sell. These products need to be safe to
manufacture, transport, store, use and either dispose of or
recover. While individual companies have specific policies
and goals, common general principles for product stewardship
include:
 |
- Fluorocarbons production includes systems that ensure
worker and community safety;
- Product Transport in both bulk and containers must comply
with all Transportation regulations. Transport and storage
must insure product safety;
- Plant design targets zero fugitive emissions;
- Coproduct formation and/or release cost effectively
minimized;
- Promote customers' cooperation to recover, recycle and/or
destroy fluorocarbons;
- HFC use in applications where emissions are limited or
there is overwhelming societal value offsetting potential
emission environmental impact;
- Fluorocarbon production and sales data published to support
global modeling of atmospheric concentration profiles.
