Muna 2020, Asia Pacific ndiyo yaive nemugove mukuru wemusika wepasi rose wekabhoni yakakangwa. China neIndia ndidzo mbiri dzinotungamira mukugadzira kabhoni yakakangwa pasi rose. MuIndia, indasitiri yekugadzira kabhoni yakakangwa ndeimwe yeindasitiri dziri kukura nekukurumidza. Kukura kwemaindasitiri munzvimbo ino uye kuwedzera kwezvirongwa zvehurumende zvekurapa marara emaindasitiri kwakakurudzira kushandiswa kwekabhoni yakakangwa. Kuwedzera kwevanhu uye kudiwa kukuru kwekugadzirwa kwemaindasitiri nekurima ndizvo zvinokonzera kuburitswa kwemarara muzviwanikwa zvemvura. Nekuda kwekuwedzera kwekudiwa kwemvura mumaindasitiri ane chekuita nekuumbwa kwemarara zvakanyanya, indasitiri yekurapa mvura inowana kushandiswa kwayo muAsia Pacific. Kabhoni yakakangwa inoshandiswa zvakanyanya pakuchenesa mvura. Izvi zvinotarisirwawo kubatsira mukukura kwemusika munharaunda iyi.
Kuburitswa kwemercury kunoburitswa kubva kumafekitori emagetsi anoshandiswa nemarasha uye kune njodzi kunharaunda neutano hwevanhu. Nyika dzakawanda dzakaisa mitemo pamusoro pehuwandu hwechepfu hunoburitswa kubva kumafekitori aya. Nyika dzichiri kusimukira hadzisati dzagadzira hurongwa hwemitemo kana hwemitemo pamercury; zvisinei, manejimendi yemercury yakagadzirirwa kudzivirira kuburitswa kwemhepo kunokuvadza. China yakatora matanho ekudzivirira nekuderedza kusvibiswa nemercury kuburikidza nemirairo yakati wandei, mitemo, nezvimwe zviyero. Tekinoroji dzepamusoro dzekudzora, kusanganisira hardware nesoftware, dzinoshandiswa kuderedza kuburitswa kwemercury. Kabhoni inoshanda ndeimwe yezvinhu zvinonyanya kushandiswa mumidziyo yematekinoroji aya kusefa mhepo. Mitemo yekudzora kuburitswa kwemercury kudzivirira zvirwere zvinokonzerwa nehupfu hwemercury yakawedzera munyika dzakawanda. Semuenzaniso, Japan yakatora mitemo yakasimba pamusoro pekuburitswa kwemercury nekuda kwechirwere cheMinamata chinokonzerwa nehupfu hwakanyanya hwemercury. Matekinoroji matsva, akadai seActivated Carbon Injection, ari kushandiswa kugadzirisa kuburitswa kwemercury munyika idzi. Saka, mitemo iri kuwedzera yekuburitswa kwemercury pasi rose iri kukurudzira kudiwa kwekabhoni inoshanda.
Zvichienderana nerudzi, musika wekabhoni yakakamurwa kuita hupfu, granular, uye pelletized nezvimwe. Muna 2020, chikamu chekabhoni yakakamurwa kuva mugove mukuru wemusika. Kabhoni yakakamurwa yakagadzirwa neupfu inozivikanwa nekushanda kwayo zvakanaka uye hunhu hwayo, senge saizi yezvidimbu zvidiki, izvo zvinowedzera nzvimbo yekunyungudika. Hukuru hwekabhoni yakakamurwa yakagadzirwa neupfu iri pakati pe5‒150Å. Kabhoni yakakamurwa yakagadzirwa neupfu ine mutengo wakaderera. Kuwedzera kwekushandiswa kwekabhoni yakakamurwa yakagadzirwa neupfu kucharamba kuchiwedzera kudiwa munguva yekufanotaura.
Zvichienderana nekushandiswa, musika wekabhoni yakakamurwa kuita mishonga yekuchenesa mvura, chikafu nezvinwiwa, mishonga, mota, nezvimwewo. Muna 2020, chikamu chekurapa mvura chakabata mugove mukuru wemusika nekuda kwekuwedzera kwemaindasitiri pasi rose. Kabhoni yakakamurwa yakaramba ichishandiswa senzira yekusefa mvura. Mvura inoshandiswa mukugadzira inosvibiswa uye inoda kurapwa isati yaburitswa mumvura. Nyika zhinji dzine mitemo yakasimba maererano nekurapa mvura uye kuburitswa kwemvura yakasvibiswa. Nekuda kwekukwanisa kwayo kunyudza kabhoni yakakamurwa nekuda kwekuoma kwayo nenzvimbo yakakura, inoshandiswa zvakanyanya kubvisa tsvina mumvura.
Nyika zhinji dzinovimba nekupinza zvinhu izvi kuti dzigadzire kabhoni yakakangwa dzakasangana nematambudziko makuru ekutenga zvinhu izvi. Izvi zvakakonzera kuvharwa kwenzvimbo dzekugadzira kabhoni yakakangwa. Zvisinei, sezvo hupfumi huri kuronga kumutsiridza mashandiro ahwo, kudiwa kwekabhoni yakakangwa kunotarisirwa kuwedzera pasi rose. Kudiwa kuri kukura kwekabhoni yakakangwa uye mari yakawanda inodyarwa nevagadziri vakakurumbira kuti vawedzere kugona kwekugadzira zvinotarisirwa kukurudzira kukura kwekabhoni yakakangwa munguva yekufanotaura.
