Imirasire y'izuba
Ikirahuri cya firime kigizwe rwose cyangwa igice cya PE firime ma-terial, ikoreshwa mugihe cyitumba cyangwa ibibanza bidakwiriye guhingwa hanze.
Ikirahuri cya firime kirashobora gufata neza ingufu zizuba, izuba ryihuta kandi birashobora gukoreshwa muguhindura ubushyuhe nubushuhe bwa firime.Amadirishya ya firime mubusanzwe ntabwo akenera gushyuha, kandi akusanya ubushyuhe binyuze muri greenhouseeffect. Ubushyuhe bwo hasi muri rusange 1 ℃ kugeza 2 ℃ hejuru cyane, kandi ubushyuhe buringaniye ni 3 ℃ kugeza 10 ℃ hejuru.
Igipimo cyo kohereza urumuri muri rusange ni 60% kugeza kuri 75%, kandi tomainaine urumuri ruringaniye, inyinshi murizo zikaba zimaze kwaguka mu majyepfo.
Ibiranga
Hamwe niterambere ryinganda za plastike, ibirahuri bya firime byamamaye kwisi yose kuko byubatswe byoroshye, byoroshye kuri uand ku giciro gito.
