Mumakumi matanhatu emakore apfuura, yekutanga yakava kuputira zvinhu kubva pakawedzerwa polystyrene (EPS) yakaiswa. Chekutanga-chizvarwa chezvemagetsi insulation composite system (ETICS) zvave kuita chirongwa chekuda kugadziridzwa. Asi zvekuita nemabhodhi akaraswa ekuzvivhara? Yakaraswa EPS yekupisa masisitimu senge yakatsva kana kuraswa. Kudzokorodza hakuna kukwanisa kusvika ikozvino. Asi izvo zvave kuda kuchinja: muTerneuzen, kuNetherlands, chirimwa chekutyaira chiri kuvakwa kuitira kudzoreredza zvinhu zvemukati zve polystyrene. Iine huwandu hwematani e3.000 pagore, kusimba kwepashure polystyrene inogona kushandurwa kuva yakakwira mhando yepolystyrene recyclate. Kugadzirisazve kunoshandiswa sechinhu chisina kuchena chezvinhu zvitsva zvinokurudzira. Iyo yekudyara chirimwa yakarongedzwa kuenda mukushanda neazvino 2019.
"Zvese zvinoramba zvichiyerera"
Chirimwa ichi chiri kuitwa nePolyStyreneLoop chirongwa (PS Loop Initiative) nerutsigiro rwemari kubva kuEuropean Commission. Mune ichi chiitiko, makambani e55 kubva kunyika dze13 akazvironga nenzira yemubatanidzwa pasi pemutemo weDutch. Kusanganisira iro reAustria remhando yeboka rekupisa masisitimu system (QG WDS) uye iyo inogadzira Austrotherm, Clemens Hecht, mutauri weQG WDS: "Iyi danho yakakosha zvikuru nekuti inovhara chikamu chekupedzisira chedenderedzwa rehupfumi hwakatenderera! "Zvese zvinogara murwizi, hapana chakarasika."
Mukubatana neFraunhofer Institute IVV, CreaCycle GmbH yakagadzira maitiro eCreaSolv, anoshandiswa kuTerneuzen. Musimboti wepasirese ndeye "yakasarudzwa yekubvisa". Mukuita kwepatiki, zvinosvibisa uye zvakasvibiswa zvinopatsanurwa nemhando dzakakosha dzekuchenesa. Zvinoenderana nemuvhenganisi, iyo yakakosha mhedzisiro inowanikwa mukucheneswa kwechinhu padhuze yemamolesi. Mhando-inokanganisa kushatisa (senge glue) ipapo inobviswa zvinyoronyoro uye ichichengetedza zvivakwa zve polymer. "Mapurasitiki akagadziriswazve kubva mumusanganiswa wakasvibiswa kana zvinhu zvinogadzirwa zvinoratidza mhandara yezvinhu," anonyora Fraunhofer Institute mune tsananguro yeCreaSolv ®. Zvinogona zvakare kureva iyo yazvino yakarongedzwa senge toxic fire retardant hexabromocyclododecane (HBCD) uye yakashandiswazve se bromine. Kunyangwe HBCD isingachashandiswi kubvira 2015, ichiripo muhombodo yekare. Austrotherm Kumaneja Director Gerald Prinzhorn: "Kune iyo ETICS, kuputsa nekugadzirisa zvakare haisi nyaya isina kukosha. Iyo inovharidzira zvinhu ine chikamu chikuru cheiyo system uye saka inofanira kudzoserwa ku100 muzana. Chigadzirwa chakatengeswa uye chakadzoserwa shure chinogona kushandiswa kuzvigadzirwa zvitsva mushure mekuita zvataurwa zvakare 1: 1. "
Indasitiri yekuvaka inobata yakawanda mikana
Mukuda kwekusimudzira, zvakadaro, kune dzimwewo dzimwe nzira dzekujaira dzemagetsi dzinovaka masisitimu system: Iyo façade yekuisa sisitimu isina glue inogona kudzoreredzwa muzvikamu zvayo zvikuru yakagadziridzwa nemugadziri Sto mukubatana neGrey University of Technology. Kana uchinge wapaza sisitimu, zvimiro zvehurongwa zvinogona kupatsanurwa zvakare nekugadzirwazve. Nekuti izvo zvinongedzo zvinokwirirwa panzvimbo yeglue. "Iyi tekinoroji inoita kuti yedu nyowani fakisheni insulation system StoSystain-R inyanye kudzokororwa uye igadziriswazve muzvikamu zvayo zvikuru," anodaro Walter Wiedenbauer, Managing Director weSto. "Uku kutsikiswa mukugadzikana uko kungangoita kushandura indasitiri."
Kwa Greta Spider, mutauri we RepaNet - Re-Use & Repair Network yeAustria, mabudiro akadaro anogamuchirwa, asi haasviki kure zvakakwana: "RepaNet inogamuchira nzira dzekuvandudza hupfumi hwedenderedzwa. Pachine zvakawanda zvinogona pano, kunyanya muindasitiri yekuvaka, uye chirongwa chekusungirirwa kwekusungirirwa pasina kunamatira uye nekuparadzaniswa kuri nani uye kugadziriswazve kusimudzira kwakanaka kubva pari zvino maonero. Nhanho inotevera inofanirwa kuve yekuti zvinhu zvinodzivirira zvinogona kushandiswa zvekare, nekuti zvimwe zviwanikwa zvinogara zvichirasika kana zvashandiswazve. "
