Kukula kwa mliriwu kwabweretsanso zinthu zapulasitiki monga zophimba nkhope, zovala zodzitetezera ndi magalasi m'maso mwa anthu.Kodi pulasitiki imatanthauza chiyani ku chilengedwe, kwa anthu, kudziko lapansi, ndipo kodi pulasitiki tiyenera kuchita bwanji moyenera?
Funso 1: chifukwa chiyani mumagwiritsa ntchito pulasitiki yambiri m'malo mwazoyika zina?
Kalekale, chakudya chinalibe katundu wothandiza ndipo chinkafunika kudyedwa kapena kuthyoledwa.Ngati simungathe kugonjetsa nyama yanu lero, muyenera kukhala ndi njala.Pambuyo pake, anthu anayesa kukulunga ndi kusunga chakudya ndi masamba, mabokosi amatabwa, mapepala, zitini zoumba mbiya, ndi zina zotero, koma zinali zosavuta kuyenda patali pang’ono.Kupangidwa kwa magalasi m'zaka za zana la 17 kunapangitsa kuti anthu azikhala ndi zopinga zabwino pakuyika.Komabe, mtengo wokwerawu mwina umapezeka kwa olemekezeka okha.Kupangidwa komanso kugwiritsa ntchito kwambiri mapulasitiki m'zaka za m'ma 1900 kunathandiza anthu kuti azitha kudziwa bwino Packaging material yotsika mtengo yokhala ndi zotchinga zabwino komanso zosavuta kupanga.Kuchokera m'malo mwa mabotolo agalasi kupita ku matumba oyikapo ofewa pambuyo pake, mapulasitiki amaonetsetsa kuti chakudya chikhoza kunyamulidwa pamtengo wotsika mtengo, kuwonjezera nthawi ya alumali, kuchepetsa mtengo wopezera chakudya, ndikupindula mamiliyoni mazana a ogula.Masiku ano, timadya matani mamiliyoni ambiri a ma CD a pulasitiki pachaka, m'malo mwa galasi kapena pepala, osanenapo za kuwonjezeka kwa ndalama zowonongeka, zipangizo zomwe zimafunikira ndi zakuthambo.Mwachitsanzo, ngati mkaka mu matumba aseptic m`malo ndi galasi botolo, alumali moyo adzakhala adzafupikitsidwa kwa chaka chimodzi kwa masiku atatu, ndi kulemera kwa phukusi kuonjezera ambiri nthawi.Kugwiritsa ntchito mphamvu komwe kumafunikira pakuyenda ndikuwonjezeka kwa Nambala ya geometric.Kuonjezera apo, kupanga ndi kukonzanso zinthu zamagalasi ndi zitsulo zimafuna mphamvu zambiri, ndipo kupanga mapepala ndi kubwezeretsanso kumafuna madzi ambiri ndi mankhwala.Kuphatikiza pa kuthetsa vuto la kusunga chakudya, kutuluka kwa zinthu zapulasitiki kwalimbikitsanso chitukuko cha magalimoto, zovala, zoseweretsa, zida zapakhomo ndi mafakitale ena.makamaka zachipatala, monga zophimba nkhope, zovala zodzitetezera, magalasi, kutiteteza ku kachilomboka.
Funso 2: pulasitiki ndi chiyani?
Pulasitiki ndi yabwino kwambiri kugwiritsa ntchito anthu ochulukirapo, koma mutagwiritsa ntchito?Chifukwa cha kusowa kwa zithandizo zofananira m'malo ambiri, mapulasitiki ena amatayidwa m'chilengedwe, ndipo ngakhale kachigawo kakang'ono ka chilumba cha zinyalala cha pulasitiki chimapangidwa mukuya kwa nyanja pamene mtsinje umalowa m'nyanja.Zimayika pachiwopsezo abwenzi athu ena padziko lapansi pano.Kusintha kwa khalidwe la ogula kumathandizanso kupanga zinyalala zapulasitikizi.Monga kutenga, kutumiza mwachangu, izi zimathandizira kwambiri miyoyo yathu, komanso zimapangitsa kuti kupanga mapulasitiki azinyalala kuchuluke.Pamene tikusangalala ndi mapulasitiki, tiyenera kuganiziranso komwe kuli koyenera mukamagwiritsa ntchito.
Funso 3: chifukwa chiyani vuto la pulasitiki lotayirira silinakhudzidwe kwambiri zaka zapitazo?
Pali mndandanda wamafakitale wokonzanso pulasitiki wapadziko lonse lapansi, womwe maiko otukuka amaika m'magulu obwezeretsanso pulasitiki ndikugulitsa kumayiko omwe akutukuka kumene pamitengo yotsika, yomwe imapindula pokonza mapulasitiki opangidwanso.Komabe, boma la China lidaletsa kutulutsa zinyalala koyambirira kwa chaka cha 2018, ndipo maiko ena omwe akutukuka kumene adatsatira, motero mayiko adayenera kuthana ndi zinyalala zawo.
Ndiye, si dziko lililonse lomwe lili ndi zida zathunthu izi.Chotsatira chake, zinyalala mapulasitiki ndi zinyalala palimodzi popanda kupita, kuchititsa mavuto ena chikhalidwe, komanso kwambiri anakopeka aliyense nkhawa.
Funso 4: Kodi mapulasitiki ayenera kubwezeretsedwanso bwanji?
Anthu ena amati anthufe ndife onyamula chilengedwe, ndipo mapulasitiki ayenera kubwerera kulikonse kumene akuchokera.Komabe, mapulasitiki nthawi zambiri amatenga zaka masauzande kuti awonongeke.Ndi kupanda udindo kusiya mavutowa kwa mibadwo yamtsogolo.Kubwezeretsanso sikutengera udindo, kapena chikondi, koma pamakampani.Makampani obwezeretsanso zinthu zomwe angapangitse anthu kukhala olemera, olemera komanso olemera ndi muzu wa kuthetsa vuto lobwezeretsanso.
Kuphatikiza apo, musagwiritse ntchito zinyalala zamapulasitiki ngati zinyalala.Ndi kutaya mafuta, kuwaphwanya kukhala ma monomers, kuwapukuta kukhala mapulasitiki, kenako kuwapanga kukhala zinthu zosiyanasiyana.
Funso 5: Ndi ulalo uti womwe ndi wofunikira kwambiri kuubwezeretsanso?
Ayenera kugawidwa!
1. kulekanitsa pulasitiki ndi zinyalala zina poyamba;
2. mapulasitiki osiyana malinga ndi mitundu yosiyanasiyana;
3. kuyeretsa granulation kusinthidwa kwa zolinga zina.
Chinthu choyamba chinachitidwa ndi akatswiri otolera zinyalala, ndipo chachiwiri chinachitidwa ndi makina apadera ophwanya ndi kuyeretsa.Tsopano pali maloboti ndi luntha lochita kupanga kuphatikiza kuphunzira mozama kumatha kuthana ndi njira yoyamba ndi yachiwiri.Tsogolo lafika.Kodi mubwera?Ponena za gawo lachitatu, talandiridwa kuti tipitirizebe kutimvera.
Funso 6: Ndi mapulasitiki ati omwe ali ovuta kuwakonzanso?
Pali ntchito zambiri zamapulasitiki, mabotolo amadzi amchere amchere wamba ndi PET, mabotolo a HDPE osambira a shampoo, ndi zida imodzi, zosavuta kubwezanso.Zopangira zofewa monga zotsukira, zokhwasula-khwasula, matumba a mpunga, kutengera zotchinga ndi zofunikira zamakina, nthawi zambiri zimakhala ndi PET, nayiloni ndi PE ndi zida zina, sizigwirizana, kotero kuti sizili zophweka kukonzanso.
Funso 7: zotengera zofewa zitha bwanji kubwezeredwanso mosavuta?
Zoyikapo zosinthika, zomwe nthawi zambiri zimakhala zamitundu yambiri komanso zimakhala ndi mapulasitiki azinthu zosiyanasiyana, ndizovuta kwambiri kukonzanso chifukwa mapulasitiki osiyanasiyanawa samagwirizana.
Pankhani ya kapangidwe kazonyamula, chinthu chimodzi ndichothandiza kwambiri pakubwezeretsanso.
CEFLEX ku Europe ndi APR ku United States apanga miyezo yofananira, ndipo mabungwe ena ogulitsa ku China akugwiranso ntchito pamiyezo yoyenera.
Komanso, mankhwala recycling ndi nkhawa.
