Ukutshintshela kwizinto ezisekwe kwibhayoloji kunika indlela ethembisayo kwizisombululo zokupakishwa ezizinzileyo kushishino lokutya nesiselo.
Kwindawo yokutya kunye nesiselo, umsebenzi ophambili wokupakisha kukusebenza njengesithintelo, ukukhusela iziqulatho ezivela kwi-pathogens kunye neengcoliseko ngelixa ugcina indawo yangaphakathi ezinzileyo ukuthintela ukukhula kwe-microbial kunye nokuwohloka kwemveliso.
Oku akwaneli nje ixesha leshelufu leemveliso ezifana neziqhamo zangaphandle kwexesha lonyaka kunye nemifuno ehamba imigama emide kodwa ikwanciphisa nenkunkuma yokutya. Ngaphandle kweenzuzo ezininzi, ukugqwesa kweeplastiki kwipakethe kuyingxaki.
Iiplastiki zithandwa ngenxa yokuguquguquka kwazo-zibonelela ngeempawu eziphambili ezifana nerhasi kunye nomphunga wamanzi okwaziyo ukungena, ukuqina, kunye nokungafihli. Ukanti, zibangela ucelomngeni olukhulu lwemekobume.
Ithathwe ubukhulu becala kumafutha efosili, ukuveliswa kweeplastiki kunegalelo ekukhutshweni kwegesi yegreenhouse, kwaye ngeqhezu kuphela eliphinda lisetyenziswe e-UK, uninzi luphela kwiindawo zokulahla inkunkuma, ezitshisiweyo, okanye njengenkunkuma eqhubekayo kwindawo yokuhlala yendalo.
Amanyathelo okunciphisa ukusetyenziswa kweplastiki ekupakisheni
Ukuqaphela irhafu yokusingqongileyo yeeplastiki eziqhelekileyo, ezenza i-40% yazo zonke izinto ezisetyenziswayo zeplastiki, amanyathelo amaninzi aqalisiwe ukunciphisa ubukho bazo ekupakisheni.
Isibhengezo sikaRhulumente wase-UK ngo-2018 serhafu entsha kwipakethe yeplastiki engaphantsi kwe-30% yomxholo ohlaziyiweyo linyathelo elinesibindi ekukhuthazeni ukusetyenziswa kwezinto ezisetyenzisiweyo.
Amanye amalinge anje ngeSicwangciso sokuSingqongileyo seminyaka engama-25 ajolise ekubeni inkunkuma yeplastiki ithintelwe ingabikho ngo-2042, kwaye i-UK Plastics Pact inethemba lokwenza zonke iipakethe zeplastiki ziphinde zisetyenziswe, ziphinde zisetyenziswe, okanye zivuthwe ngo-2025.
La manyathelo ancediswa ngamaqhinga okunyusa izinga lokuphinda asetyenziswe kunye nokuphucula iziseko zolawulo lwenkunkuma, amanyathelo abalulekileyo ekunciphiseni ukupakishwa kwendalo.
Ukunyuka kwezinto ezisekelwe kwi-bio yokupakisha
Phakathi kokutyhalela kude kwiiplastiki ezisekwe kwifosili, izinto ezisekwe kwibhayoloji zifumene ingqalelo. Ezi mathiriyeli, ziphuma kwimithombo yendalo efana nezityalo, izilwanyana, okanye umngundo, zibonakalisa enye indlela ezinzileyo.
Bakholisa ukuvelisa iigesi ezimbalwa ze-greenhouse ngexesha lemveliso kwaye zihlala zibola okanye zivundiswe. Nangona kunjalo, amagama athi "i-biodegradable" kunye ne "compostable" eza kunye ne-nuances yawo.
Ngelixa izinto eziguquguqukayo ze-biodegradable zidilika ngokwendalo ngokuhamba kwexesha, azinakuqhekeka ngokukhawuleza okanye ngokupheleleyo, ezinokuthi zenze i-microplastics. Kwelinye icala, izinto ezivundisiweyo ziyilelwe ukuba zibole phantsi kweemeko ezithile kunye namaxesha abekiweyo, ngakumbi kwizixhobo zokwenziwa komgquba kwimizi-mveliso.
Iimpawu ezinjalo zihambelana neenjongo zokusingqongileyo kodwa zikwaqaqambisa ubunzima bokutshintsha ngokupheleleyo kude neeplastiki eziqhelekileyo.
Izixhobo zoqhagamshelwano zokutya ezisekelwe kwi-bio: amathuba kunye nemingeni
Ukutshintshela kwizixhobo zoqhagamshelwano zokutya ezisekwe kwibhayoloji (ii-BBFCM) njengephepha, i-bamboo, i-chitin esuka kwi-shellfish, kunye neemveliso ezisekwe kwi-seaweed zinika amathuba anomdla.
Ezi zixhobo azinciphisi kuphela ukuthembela kwimithombo engahlaziyekiyo kodwa zikwanciphisa ezinye iimpembelelo zokusingqongileyo ezinxulumene nemveliso yeplastiki yemveli.
Nangona kunjalo, iiBBFCM ziza nemingeni yazo.
Kufuneka bahlangabezane nemigangatho engqongqo yokhuseleko ukuthintela imichiza ekufudukeleni ekutyeni, inkxalabo ebukhali ngakumbi xa ezi mathiriyeli zidibana nokutya neziselo.
Ngapha koko, ngelixa ii-BBFCMs ezifana ne-bioplastics-ephuma kwi-polymers yendalo okanye i-synthesized ngokusebenzisa iinkqubo ze-microbial-zibonelela ngokusebenza ngokulinganayo kwiiplastiki eziqhelekileyo ezisekelwe kwi-fossil, ayizizo zonke ezinokubola, kwaye izibonelelo zabo zokusingqongileyo zinokwahluka ngokubanzi.
Inyathelo elibalulekileyo lokuzinza kwishishini lokutya neziselo
Utshintsho ukusuka kwifosili ukuya kwizinto zokupakisha ezisekwe kwibhayoloji limele inyathelo elibalulekileyo elikhokelela kuzinzo kwishishini lokutya neziselo. Nangona kunjalo, olu tshintsho lufuna uqwalaselo olucokisekileyo lweepropathi zezinto eziphathekayo, iimpembelelo zokusingqongileyo, kunye neengozi zempilo ezinokubakho.
Ukwenziwa kwezinto ezintsha eziqhubekayo, ezidityaniswa nezikhokelo zolawulo ezomeleleyo kunye nemfundo yabathengi, kuya kuba yimfuneko ekuqondeni ngokupheleleyo iinzuzo zezinye izisombululo zokupakisha.
Ezi nzame azikho malunga nokutshintsha enye into ngenye kodwa malunga nokucinga ngokutsha indlela yethu yokupakisha ukuqinisekisa ikamva elizinzileyo.
