The use of a chemical called Hydro Chloro Fluoro Carbon (HCFC) -141b, used by India in foam manufacturing enterprises by January 1, 2020, has been phased out.
Hydro Chloro Fluoro Carbon
- On 31 December 2019, a notification was issued in the Gazette of India to promote environmentally friendly technologies by the Ministry of Environment, Forest and Climate Change- MoEFCC.
- The Ozone Depleting Substances (Regulation and Control) Amendment Rules, 2019 established by this notification under the Environment (Protection) Act, 1986 (Environment (Protection) Act, 1986) ) Prohibits the grant of import license for HCFC-141b.
- HCFC-141b is used in foam manufacturing enterprises which is one of the most powerful ozone depleting chemical after chloro fluoro carbon (CFCs).
- HCFC-141b acts primarily as a blowing agent in the production of rigid polyurethane foams.
- HCFC-141b is not produced in the country, so it is imported to meet all domestic requirements.
- About 7800 MT of HCFC 141-b volume has been removed from the baseline level by the year 2009 -2010 in the country with the help of technology conversion projects by Hydro Chloro Phluro Phase Out Management Plan- HPMP .
Why the need for this step?
- This step has been taken by India to reduce the Ozone Depleting Substances-ODS in a phased manner and to adopt environmentally friendly and energy efficient technologies.
- About 50% of the ozone depleting chemicals in the country were emitted due to HCFC-141b used in the foam sector.
- This holistic approach was adopted by the Ministry to engage with foam manufacturing enterprises to provide technical and financial support in non-ozone depleting substances (NON-ODS) and low global warming potential (GWP) technologies under HPMP.
- Approximately 175 foam manufacturing enterprises are covered under HPMP, of which 163 enterprises fall under the second phase of HPMP.
- Mainly cold storage buildings under the foam sector, cold chain infrastructure, automobiles, commercial refrigeration, water geysers, thermo ware, office and home furniture applications, specialized Important economic sectors related to high-value home appliances are included.
- Under Article-5 of the Montreal Protocol (developing countries) the use of HCFC141b in the foam sector has been placed at the top of the phase out management plan.
Benefits of phase-out management plan of HCFC-141b-
HPMP will be helpful in preventing erosion of the ozone layer in the stratosphere.
Techniques used in foam manufacturing enterprises that increase global warming due to climate change will be helpful if HPMP is reduced.
Montreal Protocol (1985):
The Protocol is an international treaty on ozone depleting substances that has been implemented in a phased manner to protect the ozone layer and to prevent the emission of such substances.
