Dikgetho tse 4 tse ntjha bakeng sa thepa e tala ya polasetiki e thehilweng hodima tlhaho: letlalo la tlhapi, dikgetla tsa peo ya mahapu, dikoti tsa mohlwaare, tswekere ya meroho.
Lefatšeng ka bophara, libotlolo tsa polasetiki tse libilione tse 1.3 li rekisoa letsatsi le letsatsi, 'me ke karoloana feela ea leqhoa la polasetiki e entsoeng ka peterole. Leha ho le joalo, oli ke mohloli o lekanyelitsoeng, o sa tsosolosoeng. Ho tšoenyang le ho feta, tšebeliso ea mehloli ea peterole e tla kenya letsoho ho futhumaleng ha lefatše.

Ho nkela thepa ea petrochemical sebaka ka thepa e thehiloeng linthong tse phelang ho ne ho ke ke ha fokotsa feela ho itšetleha ka mehloli e fokolang ea petrochemical, empa hape ho ne ho tla fokotsa lebelo la ho futhumala ha lefatše.
Lipolasitiki tse thehiloeng linthong tsa tlhaho li re pholosa mohato ka mohato qhafutsong ea polasetiki e thehiloeng ho peterole!
Motswalle, ua tseba eng? Likoti tsa mohlwaare, likhetla tsa peo ea mahapu, matlalo a litlhapi le tsoekere ea limela li ka sebelisoa ho etsa polasetiki!
01 Sekoti sa mohlwaare (sehlahisoa se setseng sa oli ea mohlwaare)
Khamphani e qalang ea Turkey e bitsoang Biolive e ikemiselitse ho nts'etsapele letoto la li-pellet tsa bioplastic tse entsoeng ka likoti tsa mohloaare, tse tsejoang hape e le polasetiki e thehiloeng linthong tse phelang.
Oleuropein, motsoako o sebetsang o fumanoang peong ea mohloaare, ke antioxidant e lelefatsang bophelo ba li-bioplastics ha ka nako e ts'oanang e potlakisa ho etsoa ha manyolo ka har'a lintho tse tala nakong ea selemo.
Kaha li-pellet tsa Biolive li sebetsa joaloka polasetiki e entsoeng ka peterole, li ka sebelisoa feela ho nkela li-pellet tsa polasetiki tse tloaelehileng sebaka ntle le ho sitisa potoloho ea tlhahiso ea lihlahisoa tsa indasteri le liphutheloana tsa lijo.
02 Likhetla tsa Peo ea Mahepu
Khamphani ea Jeremane Golden Compound e hlahisitse polasetiki e ikhethang e thehiloeng linthong tsa tlhaho e entsoeng ka likhetla tsa peo ea mahapu, e bitsoang S²PC, 'me e bolela hore e ka sebelisoa hape ka 100%. Likhetla tsa peo ea mahapu a tala, e le sehlahisoa se tsoang ho oli e ntšoang, li ka hlalosoa e le molapo o tsitsitseng.
Li-bioplastic tsa S²PC li sebelisoa masimong a fapaneng, ho tloha thepa ea ka tlung ea ofisi ho isa ho tsa thepa e ka sebelisoang hape, mabokose a polokelo le mabokose a polokelo.
Lihlahisoa tsa bioplastic tse "tala" tsa Golden Compound li kenyelletsa likhalase tsa kofi tse bolang tse hapileng khau, tsa pele lefatšeng, lipitsa tsa lipalesa le likopi tsa kofi.
03 Letlalo la tlhapi le makgapetla
Leano le thehiloeng UK le bitsoang MarinaTex le sebelisa matlalo a litlhapi le makgapetla a kopantsoeng le bolele bo bofubelu ho etsa polasetiki e thehiloeng linthong tse phelang e ka sebelisoang hanngoe feela joalo ka mekotla ea bohobe le li-sandwich wraps 'me ho lebelletsoe hore e tla sebetsana le lithane tse halofo ea milione tsa litlhapi tse hlahisoang UK selemo se seng le se seng.
04 Tsoekere ea limela
Avantium e thehiloeng Amsterdam e hlahisitse theknoloji e ncha ea "YXY" ea limela ho ea ho polasetiki e fetolang tsoekere e thehiloeng limela hore e be thepa e ncha ea ho paka e bolang - ethylene furandicarboxylate (PEF).
Thepa ena e sebelisitsoe tlhahisong ea masela, lifilimi, 'me e na le monyetla oa ho ba thepa e ka sehloohong ea ho paka lino tse bonolo, metsi, lino tse tahang le lero, 'me e sebelisane le lik'hamphani tse kang Carlsberg ho nts'etsapele libotlolo tsa biri tse "thehiloeng ho 100% bio-based".
Tšebeliso ea polasetiki e thehiloeng linthong tsa tlhaho ke ea bohlokoa
Lithuto li bontšitse hore thepa ea baeloji e etsa 1% feela ea tlhahiso eohle ea polasetiki, ha thepa ea polasetiki ea setso kaofela e nkiloe linthong tse ntšitsoeng ka petrochemical. E le ho fokotsa tšusumetso e mpe ea tikoloho ea tšebeliso ea mehloli ea petrochemical, ho bohlokoa ho sebelisa polasetiki e hlahisoang mehloling e nchafatsoang (mehloli ea liphoofolo le limela).
Ka ho hlahisoa ha melao le melawana ka tatellano mabapi le polasetiki e thehiloeng linthong tse phelang linaheng tsa Europe le Amerika, hammoho le phatlalatso ea lithibelo tsa polasetiki libakeng tse fapaneng tsa naha. Tšebeliso ea polasetiki e thehiloeng linthong tse phelang e tla laoloa haholoanyane le ho ata haholoanyane.
Setifikeiti sa machaba sa lihlahisoa tse thehiloeng ho bio
Lipolasitiki tse thehiloeng linthong tse phelang ke mofuta o mong oa lihlahisoa tse thehiloeng linthong tse phelang, kahoo mabitso a setifikeiti a sebetsang ho lihlahisoa tse thehiloeng linthong tse phelang a sebetsa le ho polasetiki tse thehiloeng linthong tse phelang.
Letšoao la USDA Bio-Priority la USDA la USDA, UL 9798 Letšoao la Netefatso ea Litaba tse Thehiloeng ho Bio, OK Biobased ea Belgian TÜV AUSTRIA Group, Jeremane DIN-Geprüft Biobased le I'm Green ea Brazil Braskem Company, mabitso ana a mane a lekoa bakeng sa litaba tse thehiloeng ho bio. Sehokelong sa pele, ho totobalitsoe hore mokhoa oa carbon 14 o sebelisoa bakeng sa ho lemoha litaba tse thehiloeng ho bio.
Letšoao la USDA Bio-Priority le Letšoao la Netefatso ea Litaba tse Thehiloeng ho Bio la UL 9798 li tla bonts'a peresente ea litaba tse thehiloeng ho bio leiboleng ka kotloloho; ha mabitso a thehiloeng ho Bio a OK Bio le DIN-Geprüft Bio a bontša mefuta e hakanyetsoang ea litaba tse thehiloeng ho bio tsa sehlahisoa; mabitso a I' m Green a sebelisoa ke bareki ba Braskem Corporation feela.
Ha ho bapisoa le polasetiki ea setso, polasetiki e thehiloeng linthong tsa tlhaho e nahana feela ka karolo ea thepa e tala, 'me e khetha likarolo tse nkiloeng baelojing ho nkela mehloli ea petrochemical e tobaneng le khaello sebaka. Haeba u ntse u batla ho fihlela litlhoko tsa taelo ea hona joale ea thibelo ea polasetiki, u hloka ho qala ho tloha sebopehong sa thepa ho fihlela maemo a bolang.
