In 1991, China joined the Montreal Protocol on Substances that Deplete the Ozone Layer
.
Since 2011, China has implemented the "Phase-1 Hydrochlorofluorocarbons (HCFCs) Phase-out Management Plan in the Polyurethane (PU) Foam Industry", and by the end of the first-phase phase-out plan, China has realized the elimination of HCFCs in the PU foam industry in 2013.
Consumption froze at the limit (49,020 tonnes) and exceeded the first phase (ie by 2015) compliance target of a 10% reduction from the baseline
.
In 2016, China officially began to implement the "Phase II HCFCs Elimination Management Plan for the PU Foam Industry"
.
At present, China has completed the compliance target of reducing the baseline level by 30% in 2018 and by 45% in 2020
.
It is expected that the consumption of HCFCs at the baseline level will be reduced by 80% in 2023, and by 2025, the PU foam industry will have only 3,000 tons of HCFCs left for use in the spray foam industry
.
The second stage will continue to support enterprises to carry out production process transformation, use combined polyether enterprises as a hub, provide downstream small and medium-sized enterprises with technical and raw material support, carry out technical assistance activities, etc.
, to achieve the ultimate goal of completely eliminating HCFCs in the PU foam industry in 2026 performance goals
.
In October 2018, the Ministry of Ecology and Environment issued the "Announcement on Prohibiting the Production of Refrigerator Freezer Products, Reefer Container Products, and Electric Water Heater Products Using Monofluorodichloroethane (HCFC-141b) as a Foaming Agent", realizing these three Complete phase-out of HCFC-141b in this sub-sector
.
It is planned to enact a ban on the use of HCFC-141b in the insulation pipe and solar water heater sub-sectors by the end of 2022, a ban on the use of HCFC-141b in sub-sectors other than the spraying sub-sector by the end of 2024, and a PU by the end of 2025 HCFC-141b consumption ban in the foam industry
