Kodi chinsinsi cha chitukuko cha zipangizo zozungulira nsungwi ndi chiyani?

Kuchepetsa mtengo wa utomoni wopangidwa ndi bio ndikofunikira kwambiri pakukula kwa mafakitale
Mpweya wobiriwira komanso wotsika wa kaboni ndiye zifukwa zazikulu zomwe zida zopangira zinthu zozungulira za nsungwi zasinthira chitsulo ndi simenti kuti zigwire msika wa mapaipi. Pongowerengera potengera kutulutsa kwa matani 10 miliyoni a mapaipi ozungulira a nsungwi pachaka, poyerekeza ndi mapaipi ozungulira, matani 19.6 miliyoni a malasha wamba amasungidwa ndipo mpweya woipa umachepetsedwa ndi matani 49 miliyoni, zomwe zikufanana ndi kumanga migodi isanu ndi iwiri ya malasha yocheperako yokhala ndi kutulutsa kwa matani 3 miliyoni pachaka.

Ukadaulo wozungulira nsungwi ndi wofunika kwambiri pakulimbikitsa "kusintha pulasitiki ndi nsungwi", koma ukadaulo uwu ukadali pachiyambi chake cha chitukuko. Makamaka, kugwiritsa ntchito zomatira zachikhalidwe za utomoni kudzawononga zinthu zovulaza monga formaldehyde popanga ndi kugwiritsa ntchito, zomwe zimabweretsa zovuta pakukweza ndi kugwiritsa ntchito ukadaulo uwu. Zopinga zazing'ono. Akatswiri ena akupanga ma resin opangidwa ndi bio kuti alowe m'malo mwa guluu wachikhalidwe wa utomoni. Komabe, momwe mungachepetsere mtengo wa ma resin opangidwa ndi bio komanso momwe mungakwaniritsire mafakitale akadali vuto lalikulu lomwe limafuna khama losalekeza kuchokera ku maphunziro ndi mafakitale.
