Mutori wenhau nguva pfupi yadarika akashanyira Taisho Waste Treatment Plant iri pasi peEnvironmental Bureau yeOsaka City muJapan.Pano kwete chete kunoderedza zvakanyanya kuwanda kweWaste kuburikidza nekupisa zvinopisa, asiwo zvinobudirira kushandisa tsvina inopisa kugadzira magetsi uye kupa simba rekupisa, iro rinogona kunzi rinoshandisa zvinangwa zvakawanda.
Izvo zvinodikanwa zvekupisa marara kuita mabasa akawanda panguva imwe chete kunofanirwa kuve kuchengetedzwa uye kusvibiswa kwakaderera.Mutori wenhau akaona munzvimbo yefekitori yeDazheng Waste Treatment Plant kuti hombe Waste shaft yakadzika mamita makumi mana uye ine hurefu hwe8,000 cubic metres, inogona kutakura matani zviuru zviviri nemazana mana emarara.Vashandi vanodzora kure kure crane kuseri kwegirazi rejira remadziro kumusoro, uye vanogona kubata matani matatu emarara panguva votumira kune incinerator.
Kunyange zvazvo kune Waste yakawanda, hapana kunhuhwirira kunosemesa munzvimbo yefekitari.Izvi zvinodaro nekuti kunhuhwirira kunoitwa neNzvimbo kunoburitswa nefani yekuburitsa, kuchipisa kusvika 150 kusvika 200 madhigirii Celsius nemhepo preheater, uye yozotumirwa kune incinerator.Nekuda kwekushisa kwakanyanya muchoto, zvinhu zvinonhuwa zvese zvakaora.
Kuitira kudzivirira kugadzirwa kwecarcinogen dioxins panguva yekupisa, incinerator inoshandisa tembiricha yepamusoro ye850 kusvika 950 madhigirii celsius kupisa tsvina zvachose.Kuburikidza neyekutarisisa skrini, vashandi vanogona kutarisa mamiriro ari mukati me incinerator munguva chaiyo.
Iyo huruva inogadzirwa panguva yekupisa marara inotorwa nemuunganidzi weguruva yemagetsi, uye gasi rekuburitsa rinogadziridzwa zvakare nemidziyo yekuwachisa, mafirita ekuunganidza guruva, nezvimwewo, uye inoburitswa kubva muchimney mushure mekusangana nemaitiro ekuchengetedza.
Madota ekupedzisira anoumbwa mushure mekupiswa kwemarara anopisa anongoita chikamu chimwe chete pamakumi maviri chevhoriyamu yepakutanga, uye zvimwe zvinhu zvinokuvadza zvisingagoni kudzivirirwa zvachose zvinorapwa zvisina ngozi nemishonga.Madota acho akazoendeswa kuOsaka Bay kunoraswa.
Ehe, zvidyarwa zvekuchenesa marara zvinotarisa pakupisa zvine bhizinesi rakawedzerwa, rinova rekubvisa zviwanikwa zvakakosha zvemarara makuru asingabatiki akadai semakabhati esimbi, metiresi, uye mabhasikoro.Kune zvakare akasiyana-siyana makuru ekupwanya michina mufekitori.Mushure mokunge zvinhu zvakataurwa pamusoro zvakapwanyika zvakanaka, chikamu chesimbi chinosarudzwa nemagnetic separator uye chinotengeswa sechinhu;nepo mapepa uye mamvemve akabatanidzwa nesimbi anobviswa nemhepo kuongorora, uye Zvimwe zvikamu zvinopisa zvinotumirwa kune incinerator pamwe chete.
Kupisa kunoitwa nekupisa tsvina kunoshandiswa kugadzira chiutsi, chinozoiswa pombi kumaturbines ekugadzira magetsi.Iko kupisa kunogona kupawo mvura inopisa uye kupisa kwemafekitari panguva imwe chete.Muna 2011, anenge 133,400 matani eWaste akapiswa pano, kugadzirwa kwemagetsi kwakasvika 19.1 mamiriyoni kwh, kutengesa magetsi kwaiva 2.86 mamiriyoni kwh, uye mari yakasvika mamiriyoni 23.4 yen.
Maererano nemishumo, muOsaka chete, kuchine 7 marara ekurapa marara seTaisho.Munyika yose yeJapan, kushanda kwakanaka kwemiti yakawanda yekupisa tsvina yemasipala kwakakosha zvikuru kudzivirira matambudziko akadai se "Waste siege" uye "kusvibiswa kwenzvimbo dzemvura".
