Buri wese azi ibikoresho byo gutunganya PVC. Ni ibihe bibazo by'ibikoresho byo gutunganya PVC mu nganda?

1. Ikoranabuhanga rya MBS n'iterambere biri kugenda buhoro, kandi isoko ni rinini, ariko isoko ry'ibicuruzwa byo mu gihugu riri hasi ugereranyije.

Nubwo imaze imyaka irenga 20 itera imbere, inganda za MBS zo mu gihugu ubu zikiri ntoya, kandi nta bicuruzwa by’ikigo bishobora guhangana byuzuye n’ibicuruzwa byo mu mahanga nk’ibikoresho byo gutunganya PVC. Ibigo byinshi bihari bihura n’ibibazo bitandukanye nko guhitamo ibikoresho bidahagije, inzira zidahamye zo gutunganya, no kutagira iterambere mu ikoranabuhanga ryo gutunganya. Ndetse n’ibigo byinshi ntabwo bifite ibikoresho byabyo bya styrene butadiene latex kandi bishobora kugura gusa styrene butadiene latex idashingiye kuri MBS kugira ngo ikore MBS, kandi ubwiza bw’ibicuruzwa byabo bushobora kwiyumvirwa. Kuri ubu, ibicuruzwa byinshi byashyizwe ku isoko bishingiye ku nyungu z’ibiciro kandi bikoreshwa ku bicuruzwa bya PVC bidasaba ubwiza bw’ibicuruzwa. Ku isoko ryo ku rwego rwo hejuru, umugabane w’isoko ni muto kandi ntabwo uragira ingaruka ku bigo by’amahanga. Biteganijwe ko ingano y’ibitumizwa mu mahanga mu 2006 izaba hagati ya toni 50000 na 60000, bingana na 70% by’ibikenewe byose.

2. Hari abashakashatsi bake n'ibigo by'ubushakashatsi, byananiwe kugira imbaraga zihuriweho zo gutera imbere mu bya siyansi n'ikoranabuhanga.

Nubwo MBS yashyizwe ku rutonde rw'umushinga w'ubushakashatsi ku ikoranabuhanga n'ubumenyi mu gihugu inshuro nyinshi, ntabwo iragera ku ntambwe zikomeye. Impamvu nyamukuru ni uko hari abashakashatsi bake kandi ishoramari rike mu ikoranabuhanga. Kuri ubu, iracyari ibigo by'ubushakashatsi ku nganda bikora igerageza ryigenga kandi bishaka iterambere, ariko ubu buryo bw'ubushakashatsi n'iterambere bushobora gufatwa nk'ubw'abatarabigize umwuga ugereranije n'amatsinda y'abanyamahanga n'amatsinda manini y'ubushakashatsi ku bumenyi.

3. Kuri ubu, urwego rw'ibikoresho byo gutunganya PVC mu Bushinwa ruri hafi y'urw'ibicuruzwa byo mu mahanga, ariko kubera ibiciro bya CPE, biragoye kubyamamaza. Kujya ku isi no guhangana n'ibicuruzwa byo mu mahanga ku isoko mpuzamahanga bizaba amahitamo meza. Ariko, ibicuruzwa bimwe biriho ubu n'ihindagurika rike bizaba ikibazo cyihutirwa ku bahanga mu nganda kugira ngo bakemure ikibazo.
