Pamene chitukuko chokhazikika padziko lonse lapansi chikupitilira kukula, ogula akuyika zofunikira ziwiri pa magwiridwe antchito azinthu ndikusamalira chilengedweNdi ubwino wake wapadera wokhala wopepuka, wokhazikika, wosamalira chilengedwe, komanso wotchipa,mbale za udzu wa tiriguChadziwika bwino pakati pa mbale zachikhalidwe zapulasitiki, nsungwi, ndi PLA (polylactic acid), zomwe zakhala chisankho chabwino kwambiri pamsika. Zakudya zatsopanozi zikukonzanso msika wa mbale zapadziko lonse lapansi kudzera mu magwiridwe antchito ake abwino komanso mtengo wake - zikuyembekezeredwa kuti kukula kwa msika kudzafika madola 302.7 biliyoni aku US pofika chaka cha 2034.

Zakudya zophikira udzu wa tirigu zili ndiubwino woonekeratukuposa mbale zapulasitiki zachikhalidwe. Ngakhale mbale zapulasitiki ndizotsika mtengo, ndizowononga kwambiri chilengedwe; kuwonongeka kwake kumatenga zaka mazana ambiri ndipo kumawonjezera kuipitsa kwa pulasitiki padziko lonse lapansi. Mosiyana ndi zimenezi, mbale za udzu wa tirigu zimapangidwa ndi zinyalala zaulimi, pogwiritsa ntchito mokwaniraudzu wa tiriguzomwe zikanapsa, zomwe sizingochepetsa mpweya woipa wowononga chilengedwe komanso zimathandiza kuti zinyalala zizigwiritsidwa ntchito bwino. Kuphatikiza apo, mbale zophikira tirigu zimakhala zopepuka ndi 20% kuposa pulasitiki, zomwe zimathandiza kuti zinyamulidwe ndi kugwiritsidwa ntchito, ndipo kapangidwe kake ka ulusi wolimbitsa kangawonjezere kukhazikika, kupewa vuto lakuti pulasitiki yotsika mtengo imatha kusweka ndi kusinthika ikatentha kwambiri kapena kupanikizika.

Poyerekeza ndi mbale zophikira zamatabwa zopangidwa ndi nsungwi, mbale zophikira za udzu wa tirigu zili ndi ubwino wambiri pakugwira ntchito bwino komansokukhazikikaNgakhale kuti mbale zamatabwa a nsungwi nazonso ndi zachilengedwe, zimafunika kudula zinthu zomwe zimakula mofulumira koma zimakhala zochepa. Komanso, pamwamba pake pali mabowo ndipo mafuta ndi chinyezi zimayamwa mosavuta, zomwe zimapangitsa kuti nkhungu ikule komanso kuti nthawi yogwira ntchito ifupikitsidwe. M'malo mwake, mbale za udzu wa tirigu zili ndi malo opanda mabowo, zimapirira nkhungu ndi madontho, ndipo zimathasungani batangakhale mutagwiritsa ntchito mobwerezabwereza. Nthawi yomweyo, ndi yopepuka kuposa mbale zamatabwa zopangidwa ndi nsungwi, zomwe zingachepetse ndalama zoyendera komanso kuchuluka kwa mpweya m'mabizinesi.

Monga mbale yodziwika bwino yophwanyika,Zakudya za patebulo za PLAZili ndi vuto pa mtengo wake komanso magwiridwe antchito ake poyerekeza ndi zophikira za udzu wa tirigu. Zophikira za PLA zimapangidwa kuchokera ku chimanga kapena nzimbe, zomwe zimapangitsa kuti pakhale ndalama zambiri zopangira zomwe pamapeto pake zimaperekedwa kwa ogula. Kuphatikiza apo, zimakhala zofooka, makamaka zosavuta kuwonongeka m'malo otentha kwambiri, ndipo kuwonongeka kwake kumafuna mikhalidwe inayake yopangira manyowa m'mafakitale. Mosiyana ndi zimenezi, zophikira za udzu wa tirigu zimakhala zotsika mtengo ndi 15%-25% kuposa PLA, zomwe zimakhala ndi ubwino waukulu pamtengo wake. Zitha kuwonongeka mwachilengedwe m'miyezi 6-12 pansi pa mikhalidwe yanthawi zonse yopangira manyowa, ndipo nthawi yomweyo zimakhala ndi kukhazikika kwabwino komansokukana kutentha.

Katswiri wa mafakitale anati: “Ziwiya zophikira tirigu zimalongosola molondola mavuto omwe alipo kale — ndizopepuka kugwiritsa ntchito tsiku ndi tsiku, zokhazikika pakugwiritsa ntchito, zoteteza chilengedwe padziko lapansi, komanso zotsika mtengo kwa mabizinesi ndi ogula.” Chifukwa cha kulimba kosalekeza kwa mfundo zoletsa pulasitiki padziko lonse lapansi, kukhazikika kwakhala chinthu chofunikira kwambiri pogula. Ziwiya zophikira tirigu zikuyembekezeka kukhala ndi gawo lalikulu pamsika, kupereka yankho lopambana la chitetezo cha chilengedwe ndi kugwiritsa ntchito moyenera, ndikukhala chizindikiro chatsopano m'munda wa ziwiya zophikira padziko lonse lapansi ndi zapadera zake.ubwino wosiyana.
