Kutheni le nto imveliso yeswekile ithandwa kangaka?
Ngophuhliso loqoqosho lwehlabathi, ukubaluleka kokusetyenziswa kwamandla ngokufanelekileyo, ukunciphisa ukungcoliseka kwendalo, ukunciphisa ukuphindaphinda kweengozi zokuvelisa ukhuseleko, ukuthintela iimeko ezingxamisekileyo zokusingqongileyo, kunye nokuqinisekisa ukuba ukhuseleko lobomi luye lwaba lubalasele.
Kwiminyaka yakutshanje, ngokukhululwa "kokuvalwa kweplastiki" kunye nokukhuthaza ukukhuselwa kwendalo, ukuqonda kwabantu ngokukhuselwa kwendalo kuye kwaqiniswa ngokuthe ngcembe, kwaye ithemba lophuhliso lweebhokisi zesidlo sasemini ziya kuba ngcono kwaye zibe ngcono.Namhlanje masithethe ngesizathu sokuba imveliso yeswekile ithandwa kangaka ehlabathini.
Yintoni ingxowa yommoba?
I-Bagasse yimveliso yemveliso yeswekile kunye nemathiriyeli ekrwada eqhelekileyo yeentsinga zephepha.Ummoba sisikhondo esifana nesityalo esikhula ngonyaka omnye.Umyinge wefiber ubude yi-1.47-3.04mm, kunye ne-bagasse fiber ubude yi-1.0-2.34mm, efana nefayibha ebanzi.I-Bagasse yinto efanelekileyo ekrwada yokwenza iphepha.
I-Bagasse yintsinga yengca.Kulula ukupheka kunye ne-blanch.Isebenzisa iikhemikhali ezincinci kwaye iqulethe i-silicon encinci kunemithi, kodwa ingaphantsi kunezinye izinto eziluhlaza zefiber.Ke ngoko, i-bagasse pulping kunye netekhnoloji yokubuyisela i-alkali kunye nezixhobo zivuthiwe kwaye zilula kunezinye izinto zefiber ekrwada.Ke i-bagasse yimathiriyeli ekrwada enexabiso eliphantsi yokucofa.
Amashishini kufuneka asebenzise izixhobo ezivuselelekayo ngokukhawuleza.I-Bagasse isebenzisa ukukhutshwa okuphantsi okunxulumene namandla, okunceda ekunciphiseni ukufudumala kwehlabathi.Ifuna amandla amancinci ukwenza kuba yifayibha eshiyekileyo ekusetyenzweni kweswekile.
Ngaphezu koko, yomelele kwaye ikhuselekile kumaqondo obushushu aphezulu, okwenza kube yinto eluncedo kwiindawo zabathengi.
Imarike yeBagasse
Uphando lucebisa ukuba imakethi yokupakisha ye-pulp ebunjiweyo inokugqithisa i-4.3 yeebhiliyoni zeedola ngo-2026.
Ngoku lixesha lokujonga kumthombo ozinzileyo wokwenziwa kweemveliso ze-pulp ezibunjiweyo, inkunkuma yeswekile.Siyakwazi ukufikelela kwezinye iindlela ezizinzileyo kuba ummoba yeyona mveliso yokutya ikhula ngokukhawuleza.
Ukhetho olukrelekrele.
Ukusebenzisa inkunkuma yezolimo yeyona ndlela ingcono.Le nkunkuma iphuma kwimveliso sele iveliswa, endaweni yokuba ikhuliswe ngokukodwa njengemithi, ethatha iminyaka emininzi ukukhula.Xa kuthelekiswa nephepha, i-bagasse nayo ifuna igalelo elincinci kakhulu ukuvelisa inani elifanayo le-pulp.
Eli lithuba elingahoywayo xa ukhangela ukupakishwa okuzinzileyo ngokwenene.Kukho malunga nama-80 amazwe avelisa iswekile kwaye kukho amandla amakhulu okusetyenziswa ngcono kwentsalela ye-fibrous eyaziwa ngokuba yi-bagasse.
Izibonelelo ezibalulekileyo ze-bagasse ziquka:
I-microwave kunye ne-oven ikhuselekile
Iyakwazi ukuphatha ulwelo olushushu ukuya kuthi ga kwi-120 degrees celsius
I-oveni ikhuselekile ukuya kuthi ga kwi-220 degrees Celsius.
Iibhokisi zesidlo sasemini ezivumelana nokusingqongileyo ezenziwe ngezinto ezinokubola, izinto ezinokubola ngokupheleleyo, iigranuli ezinokubola, isitatshi sezinto ezibolayo kunye nezinye izinto ezinokonakala ngokupheleleyo nangokukhawuleza emhlabeni kunye nokusingqongileyo ngokwendalo ngokweemfuno zoyilo, ezingeyiyo ityhefu, azingcoliseki, kunye nevumba- simahla.Ayiyi kutshabalalisa isakhiwo somhlaba, kwaye ifezekise ngokwenene "ukusuka kwindalo, kodwa nakwindalo", eyona nto ithatha indawo engcono yokupakishwa kweplastiki kunye nephepha.
