Warshadaha qalabka guriga ayaa gabi ahaanba meesha ka saaray qaboojiyaha R22 ee tirinta
Sida uu dhigayo Protocol-ka Montreal, qaboojiyaha R22 ayaa lagu joojiyay wadamada horumaray, waxaana wali laga soo saari karaa wadamada soo koraya, laakiin wax soo saarkiisa iyo isticmaalkiisu waa 2030.
Janaayo 26, 2021, Wasaaradda Deegaanka iyo Deegaanka ayaa soo saartay Ogeysiiska Soo saarista 2021 Soo saarista, Isticmaalka iyo Kootada Soo dejinta ee Walxaha baabi'inaya Ozone (kadibna loo tixraacayo Ogeysiiska). Marka loo eego Sharciga Jamhuuriyadda Dadka ee Shiinaha ee ka hortagga iyo xakamaynta wasakhowga hawada, Xeerarka Maareynta Walxaha baabi'iya lakabka Ozone iyo qodobbada kale ee khuseeya, 20 shirkadood ayaa la soo saari doonaa kootada wax soo saarka ee 292,795 tan oo ah hydrochlorofluorocarbons ( HCFC) sanadka 2021, iyo 46 unug ayaa la soo saari doona kootada isticmaalka ee 31,726 tan oo hydrochlorofluorocarbons sanadka 2021.
Marka la barbar dhigo 2020, kootada wax soo saarka ee hydrochlorofluorocarbons (HCFCS) oo ay ku jirto HCFC-22 waxba iskama beddeli doonaan 2021, halka kootada isticmaalka si weyn loo dhimi doono, taas oo sii fogaynaysa HCFCS ee warshadaha qalabka guriga ee Shiinaha.
Kootada wax-soo-saarka hCFC-ku-koon yahay (HCFC) waxaa loo soo saari doonaa hCFC-141B, HCFC-142B, HCFC-22, HCFC-123, HCFC-124 iyo HCFC-133A. Waxaa ka mid ah, HCFC-141B waa wakiilka xumbo-samaynta ee loo isticmaalo qaboojiyaha iyo warshadaha kuleyliyaha biyaha. Sida nidaamka xumboynta ee warshadaha qaboojiyaha ayaa loo cusboonaysiiyay HFC-245FA + nidaamka xumboynta cyclopentane, iyo Janaayo 1, 2019, warshadaha kuleyliyaha biyaha ayaa gabi ahaanba mamnuucay isticmaalka HCFC-141B. Hcfc-141b si yar iyo si ka yar ayaa loo isticmaalay warshadaha qalabka guriga. Wadarta kootada wax soo saarka hCFC-141B sanadka 2021 waa 50,878 tan, oo aan waxba iska bedelin 2020.
Marka la barbardhigo kootada wax soo saarka ee HCFC-22, wadarta isticmaalka kootada hCFC-22 ee warshadaha qaboojinta guriga ee 2021 waa 31,726 tan, hoos u dhac 3,489 tan ah 35,215 tan sanadka 2020. Tani waxay si dhow ula xiriirtaa qaboojiyaha warshadaha qaboojinta guriga. Qaybta suuqa ee qaboojiyaha HCFC-22 ee warshadaha qaboojiyaha guriga waxay ahayd qiyaastii 20% sanadka 2019, saamigani wuxuu sii wadi doonaa inuu hoos u dhaco 2020. Warshadaha qaboojiyaha gudaha ee Shiinaha ayaa sameeyay guulo la taaban karo oo ku saabsan joojinta HCFC-22.
Istaraatiijiyadda maaraynta wejiga-baxa ee HCFC-22 ee warshadaha qaboojiyaha gudaha ee Shiinaha laga bilaabo 2021 ilaa 2026 waxaa ansixiyay Guddiga Fulinta ee Sanduuqa Dhinacyada badan, waxayna ballan qaaday in ay baabi'iso 70% isticmaalka hCFC-22 marka la gaaro 2026, kaas oo ayaa ka badan inta looga baahan yahay jadwalka hab-maamuuska Montreal si loo gaaro hCFC-22 dhimis. Waxaan wax badan ku biirin doonnaa hirgelinta Shiinaha ee Hab-maamuuska Montreal.
