I-Bioplastiki
Ngokuxhomekeke kwizinto eziphathekayo, ixesha elithathayo ukuze i-bioplastics ifakwe ngokupheleleyo i-compost inokuthatha ixesha elahlukileyo kwaye kufuneka ifakwe kwi-compost kwizibonelelo zorhwebo, apho amaqondo okushisa aphezulu anokufumaneka, kwaye phakathi kwe-90 kunye ne-180 yeentsuku.Uninzi lwemigangatho ekhoyo yamazwe ngamazwe ifuna ukuba i-60% ye-organism ithotywe kwiintsuku ezili-180, kunye neminye imigangatho efuna i-resin okanye i-compostable products.Kukwabalulekile ukwahlula phakathi kwento enokubola kunye ne-biodegradable kunye ne-compostable, njengoko la magama esetyenziswa rhoqo ngokutshintshana.
Iplastiki enokubola
Iplastiki enokubola luhlobo lweplastiki oluya konakaliswa ziintsholongwane zendalo (ezifana neebhaktheriya, umngundo, njl.njl.) ekuhambeni kwexesha.Qaphela ukuba akukho sinyanzeliso sokushiya "iintsalela ezingenayo ityhefu", okanye ixesha elifunekayo lokuchithwa kwezinto eziphilayo.
Ukurisayikilishwa kwakhona kubalulekile kwindalo esingqongileyo, kwaye ngenxa yesi sizathu sikwanalo nephepha leengxowa zokurisayikilisha ezinolwazi olunomdla.
Iplastiki enokubola
Iiplastiki ezonakaliswayo ziquka zonke iindidi zeeplastiki ezonakeleyo, kubandakanywa iiplastiki ezinokubola kunye nezivundisiweyo.Nangona kunjalo, iiplastiki ezingaboliyo okanye ezingavundisiyo ziqhele ukusebenzisa “iplastiki eyonakalayo” ileyibhile.Uninzi lweemveliso zisebenzisa iileyibhile zeplastiki ezinokubola, eziya kuthotywa ngenxa yefuthe lomzimba kunye neekhemikhali.Umsebenzi webhayoloji awuyonxalenye enkulu yokuthotywa kwezi mveliso, okanye inkqubo icotha kakhulu ukuba ibekwe kuhlelo olunokonakala okanye oluvundisiweyo.
Iindidi zeplastiki ezonakeleyo
Isitatshi esekwe
Ezinye iimveliso zeplastiki ezinokonakala zenziwe ngestatshi sombona.Ezi zixhobo zifuna ubukhulu becala imekobume yemicrobial esebenzayo phambi kokuba zithobeke, njengeetiphu okanye umgquba, ezinye ziya kuthotywa ngokupheleleyo kule meko, ngelixa ezinye ziya kugqobhoza kuphela, ngelixa iinxalenye zeplastiki zingayi kuthotywa.Amasuntswana eplastiki aseleyo anokuba yingozi emhlabeni, kwiintaka nakwezinye izilwanyana zasendle kunye nezityalo.Nangona ukusetyenziswa kwezithako ezivuselelekayo kubonakala kukhangayo ngokomgaqo, ababoneleli ngendlela efanelekileyo yophuhliso.
I-Aliphatic
Olunye uhlobo lweplastiki eyonakalayo lusebenzisa i-aliphatic polyesters ebiza kakhulu.Ngokufanayo nestatshi, zixhomekeke kumsebenzi we-microbial we-compost okanye i-landfills ngaphambi kokuba zithotywe.
Ifotodegradable
Ziya kuthotywa xa zibekwe elangeni, kodwa aziyi kuthotywa kwindawo yokulahla inkunkuma, imijelo ehambisa amanzi amdaka, okanye kwezinye iindawo ezimnyama.
Ioksijini enokubola
Ezi mveliso zingasentla zithotywa yinkqubo yokuthotywa kwe-hydration, kodwa eyona ndlela iluncedo kunye neyoqoqosho kwi-teknoloji entsha kukuvelisa iplastiki, kwaye iplastiki iyancipha yinkqubo ye-OXO yokuthotywa.Ithekhnoloji isekelwe ekuqalisweni kwenani elincinci lezongezo ezithobileyo (ngokuqhelekileyo i-3%) kwinkqubo yokuvelisa eqhelekileyo, ngaloo ndlela iguqula iipropati zeplastiki.Ayixhomekekanga kwii-microorganisms ukudiliza iiplastiki.Iiplastiki ziqala ukuthotywa ngokukhawuleza emva kokuveliswa kunye nokukhawulezisa ukuthotywa xa zibonakaliswe kubushushu, ukukhanya okanye uxinzelelo.Le nkqubo ayinakuguqulwa kwaye iyaqhubeka de izinto zincitshiswe kuphela kwi-carbon dioxide kunye namanzi.Ngoko ke, ayiyi kushiya amaqhekeza e-petroleum polymer emhlabeni.
