I-China yaqala ucwaningo nokuthuthukiswa kobuchwepheshe obukhuzi obukhulu ngo-1980, kepha eChina kuze kube manje, ngoba ingcindezi yokukhishwa kwemishini yokukhipha kakhulu ye-CO₂ iphezulu lapho imishini isebenza ngokujwayelekile, futhi imishini eyenziwe ngabakhiqizi bemishini ehlukahlukene isetshenziswa kakhulu ngesandla, isici sezingozi siphezulu, Ukuphepha nokuthembeka kuphansi, futhi umsebenzi wezandla usetshenziswa kakhulu. INantong Wisdom Supercritical Science & Technology Development Co., Ltd. iyinkampani yobuchwepheshe obuphakeme ezinikele ekuhlanganisweni kokuthuthukiswa kobuchwepheshe obukhulu oketshezi kanye nokukhiqizwa kwemishini. Inkampani idlulise isitifiketi sohlelo lwekhwalithi (GB / T 19001-2016 / i-ISO 9001: 2015), igxile ekuhlolweni okwenziwe ngokwezifiso, Imishini yezinga lokushayela kanye nezimboni yokukhishwa uketshezi, ukusabela, ukomisa, izinhlayiya ze-ultrafine neminye imishini. Ukuze kuthuthukiswe imishini yokukhishwa kwasekhaya i-CO₂, iNkampani isebenzise ngokugcwele isipiliyoni seminyaka engama-30 ekwakhiweni kwenqubo yoketshezi kakhulu nokukhiqiza imishini, futhi yabambisana neShanghai Jiao Tong University ukuthuthukisa imishini yokukhishwa okuzenzakalelayo ye-CO₂ ehlakaniphile, egcwalise ingalutho yasekhaya.
