Hay'adda Cusboonaysiinta Tigray (EFFORT) ayaa heshiis la saxiixatay shirkadda injineerinka Shiinaha ee ECE Engineering si ay u dhisto warshaddii ugu horreysay ee PVC resin (polyvinyl chloride) oo ku taal degmada Alato ee Mekele, caasimadda gobolka Tigray, iyadoo ku kacaysa 5 bilyan oo Birr (US$250 milyan marka loo eego qiimaha sarrifka hadda).
Qandaraaska EPC, oo shalay lagu saxiixay Sheraton Addis Hotel, ayaa la bixiyay ka dib markii la sameeyay tartan dheer oo bilaabmay 2012. Mashruuca ayaa markii dambe dhowr jeer dib loo bixiyay ka hor inta aan ugu dambeyntii qandaraaska la siin ECE, oo ogolaatay inay dhammaystirto mashruuca 30 bilood gudahood laga bilaabo bilowga shaqada.
Warshadda waxaa la filayaa inay soo saarto 60,000 oo tan oo ah resin PVC ah sannadkii iyadoo leh darajooyin tayo leh oo u dhexeeya SG1 ilaa SG8. Intaa waxaa dheer, dhismaha wax soo saarka kiimikada waxaa ku jiri doona taxane ah khadadka wax soo saarka kale, oo ay ku jiraan warshad chlor-alkali ah, warshad vinyl chloride monomer (VCM), khad wax soo saar PVC ah, warshad daaweynta biyaha, warshad dib u warshadayn qashinka ah, iwm.
Madaxa fulinta ee EFFORT Azeb Mesfin, oo ah carmalkii ra'iisul wasaarihii geeriyooday, ayaa saadaalisay in marka mashruuca la dhammeeyo, qiimaha uu abuuro uu si weyn u kordhin doono qiimaha guud ee kooxda deeq-bixiyeyaasha.
Resin-ka Polyvinyl chloride waa kiimiko warshadeed oo muhiim ah oo baahi weyn u qabta gudaha iyo dibaddaba. Khubaradu waxay sheegayaan in kiimikadani ay muhiimad istiraatiiji ah u leedahay soosaarayaasha, gaar ahaan warshadaha balaastikada ah ee Itoobiya. Hadda, lacag badan oo qalaad ayaa lagu bixiyaa soo dejinta badeecada, gaar ahaan wadamada soo saara saliidda, maadaama sidoo kale laga soo saari karo saliidda cayriin ee la sifeeyay.
PVC adag ayaa si weyn loogu isticmaalaa tuubooyin dareere ah hababka yaraynta, halka PVC-ga dareeraha ah sidoo kale loo isticmaali karo dahaarka fiilooyinka iyo hababka wax soo saarka ee la xiriira.
Azeb waxay sheegtay in fikradda warshadda ay lahayd ninkeeda, ayna ku faraxsan tahay in mashruuca la hirgeliyay. Waxay sidoo kale sheegtay in SUR iyo Mesfin Engineering ay door muhiim ah ka ciyaari doonaan geeddi-socodka dhismaha mashruuca iyo dhammaystirkiisa guusha leh.
Deegaanka mashruucu wuxuu hodan ku yahay kaydka dhagaxa nuuradda, kaas oo ah agab muhiim u ah warshadaha resin-ka PVC.
