Richard Mayer txoj kev tsim kho, tseem hu ua "Lub Koom Txoos ntawm Jubilee", tau teem sijhawm ua ke nrog kev sib cav 2000 xyoo, uas tau ua koob tsheej xyoo 2000. Tus neeg saib xyuas qhov tseem ceeb ntawm qhov kev tsim kho yog tsev Italian chaw tsim khoom Italcementi Group. Yuav kom ntseeg tau tias cov daus-dawb qhob "pob zeb" ntawm lub tsev teev ntuj tshiab tsis tas yuav tsum tau ntxuav ntau zaus, cov kws tshaj lij ntawm cov tuam txhab no tau siv lawv txoj kev txhim kho tshiab - daim ntaub dawb thaiv tus kheej phab ntsa. Kev tsis paub txog lawv thaum lub sijhawm, vim tias muaj cov ntsiab lus ntawm titanium dioxide, cov xim dawb, cov xim pleev plhu plaster no nqus tau cov pa hluav taws thiab lwm yam khoom siv hauv lub nroog smog.

Qhov kev sib xyaw no yog siv hauv cov xim pleev xim zoo sib xws thiab qub, vim nws muaj cov yam ntxwv ntawm photocatalyst: hauv kev tshav ntuj, nws nce cov tshuaj tiv thaiv oxidation ntau zaus. Nyob rau tib lub sijhawm, tsis tsuas yog lub nkhawb ntawm phab ntsa saum npoo yog tshem, tab sis kuj yog cov huab cua nyob ib puag ncig nws.

Qhov kev tshawb pom no tau nug cov lus nug txog ntawm cov khoom siv dav siv hauv kev tsim kho hauv nroog. Raws li kev tshawb nrhiav, huab cua nyob rau ntawm qhov deb ntawm 2.5 m los ntawm lub faadeade, npog nrog cov xim muaj xim nrog titanium dioxide, muaj 70% tsawg dua ntau cov khoom siv sib xyaw ntau dua li qhov nruab nrab hauv nroog. Ntawd yog, cov neeg taug kev nqus tau cov pa tshuaj tsawg dua thaum lawv hla los ntawm cov tsev uas tau kho nyob hauv txoj kev no.

Cov kev xaiv rau kev siv photocatalytic cement rau paving asphalt txoj kev kuj tau txiav txim siab. Raws li kev sim, nws tau siv rau 300-metres qhov ntev ntawm txoj kev loj nyob ze Milan. Kev ntsuas ntsuas pom tias nrog kev thauj mus los ntawm nruab nrab ntawm 1000 lub tsheb hauv ib teev, qhov txo qis hauv cov ntsiab lus ntawm nitrogen oxides hauv huab cua ntawm theem av yog 60%.

Qee cov kws tshaj lij tau tsis ntseeg txog qhov kev tshawb pom ntawm Italcementi cov neeg ua haujlwm: hauv lawv lub tswv yim, nws yog qhov tsim nyog los txo qis cov pa paug ntawm cov tshuaj phem, thiab kom tsis txhob rhuav tshem lawv cov txiaj ntsig - smog. Ntxiv rau, yuav luag txhua catalysts zoo li poob lawv cov hauj lwm dhau sij hawm.

Thaum cov kws tshawb fawb tab tom daws qhov teeb meem no, peb tsuas tuaj yeem qhuas cov daus-phab ntsa dawb ntawm lub tsev teev ntuj ntawm Dio Padre Misericordioso, ci ntsa iab hauv kev sib piv nrog cov pob qij txha ntawm cov pob zeb ua pob zeb, uas tsis tau them nrog titanium av.
