Walxaha balaastigga ah waxaa lagu qeexaa inay yihiin bioplastic haddi ay tahay mid noole ku salaysan, baayodegradable, ama labadaba. Taasi waa, bioplastics-ku waxay noqon karaan kuwo noole ama biodegradable ah, ama waxay ka koobnaan karaan labadaba.

Bioplastics inta badan

• bayooloji ku salaysan,
• noolayn karo,
• Ama baco ay labaduba yihiin.

Bioplastics waxay leeyihiin sifooyin la mid ah balaastikada caadiga ah. Si kastaba ha ahaatee, waxa kale oo ay leedahay raadka kaarboonka oo yaraatay ama waxay leedahay doorashooyin maaraynta qashinka sida composting.

Bioplastics waa qayb muhiim ah oo ka mid ah dhaqaalaha noolaha waana qayb si degdeg ah u horumaraysa iyo waax cusub oo awood u leh in ay kala saarto kobaca dhaqaalaha ee xaalufka khayraadka iyo saamaynta deegaanka.

Bioplastics waa qoys kala duwan oo agab ah oo leh sifooyin kala duwan. Asal ahaan waxa loo qaybiyaa saddex kooxood oo waaweyn:

• Biyo-ku-salaysan ama qayb ka mid ah baco-salaysan, balaastiig aan noolayn karin (sida PE, PP ama PET) ama polymer-yada waxqabadka farsamada noole ku salaysan (sida PTT ama TPC-ET)
• Caagag, labadaba noole ku salaysan iyo nooledegradable (sida PLA iyo PHA ama PBS)
• Bacaha noolaha ah ee ku salaysan ilaha fosilka (sida PBAT)

Maanta, bioplastics-ku waxay ka dhigan tahay boqolkiiba hal qiyaastii 370 milyan oo tan oo balaastiig ah oo la soo saaro sannadkii. Laakin marka ay baahidu sii kordheyso oo ay soo baxaan agab aad u casrisan, codsiyo iyo alaabooyin, suuqa ayaa si firfircoon u koraya.

Caagagga waara sida PE, PP, PET ama PVC waxay leeyihiin astaamo la mid ah noocyada caadiga ah. Bioplastics-yadani waxay farsamo ahaan u dhigmaan kuwa dhiggooda ah ee fosil Wali waxay kaa caawinaysaa dhimista raad-raaca kaarboonka ee badeecada. Sido kale si farsamaysan ayaa dib loo warshadayn karaa iyadoo la raacayo durdurrada dib-u-warshadaynta ee jira.

Dhanka kale, cellulose cusub ama walxo istaarij ku salaysan sida PLA, PHA waxay bixiyaan xalal cusub oo dhamaystiran sida compostability iyo, xaaladaha qaarkood, guryaha xannibaadda oo la hagaajiyay. Iyada oo ay weheliso korodhka kala duwanaanta walxaha bioplastic, dabacsanaanta, adkaysiga, daabacaadda, daahfurnaanta, xannibaadda, caabbinta kulaylka, gloss iyo waxyaabo kale oo badan ayaa si weyn loo hagaajiyay.

Ururkayagu had iyo jeer wuxuu raacaa halbeegyada gudaha iyo dibadda, xeerarka sharciga ee lagu dabaqi karo iyo dhaqamada guud ee la aqbali karo ee shahaadaynta iyo daraasadaha calaamadaynta, sidoo kale waxay leedahay shaqaale tababaran oo khibrad leh iyo tas-hiilaadyo horumarsan oo tignoolajiyadeed. Xaaladdan oo kale, codsanaya ganacsiyada,Waxa kale oo ay bixisaa shahaado compost iyo C-Label (Compost Summadaynta) adeegyada calaamadaynta compost.
