Popanda kulongedza pulasitiki, zinthu zambiri zomwe ogula amagula sizingapite kunyumba kapena kusitolo, kapena kukhala ndi moyo wabwino kwautali wokwanira kudyedwa kapena kugwiritsidwa ntchito.
1. N'chifukwa Chiyani Mumagwiritsira Ntchito Zopaka Zapulasitiki?
Koposa zonse, mapulasitiki amagwiritsidwa ntchito chifukwa cha kuphatikiza kwapadera komwe amapereka;Kukhalitsa: Maunyolo aatali a polima omwe amapanga mapulasitiki opangira zinthu amapangitsa kuti zikhale zovuta kwambiri kuthyoka. Chitetezo: Zovala zapulasitiki sizimaphwanyika ndipo sizigawika kukhala zipande zowopsa zikagwetsedwa.Kuti mudziwe zambiri za chitetezo cha ma CD a pulasitiki, komanso chitetezo chake pokhudzana ndi chakudya, pitani ku chitetezo cha pulasitiki.
Ukhondo: Zovala zapulasitiki ndizoyenera kulongedza zakudya, mankhwala ndi mankhwala.Ikhoza kudzazidwa ndi kusindikizidwa popanda kulowererapo kwa anthu.Zida zomwe zimagwiritsidwa ntchito, mapulasitiki opangira zida ndi zowonjezera, zimakwaniritsa malamulo onse okhudzana ndi chitetezo chazakudya kumayiko ndi European Union.Zopangidwa ndi pulasitiki nthawi zambiri zimagwiritsidwa ntchito ngati zida zamankhwala zomwe zimalumikizana kwambiri ndi minofu ya thupi ndipo zimagwirizana ndi chitetezo chapamwamba kwambiri pakugwiritsa ntchito kwawo kupulumutsa moyo.
Chitetezo: Zovala zapulasitiki zimatha kupangidwa ndikugwiritsidwa ntchito ndi zotsekera zowoneka bwino komanso zosagwirizana ndi ana.Kuwonekera kwa paketi kumathandizira ogwiritsa ntchito kuwona momwe zinthu zilili asanagule.Kulemera Kwambiri: Zinthu zolongedza za pulasitiki ndizochepa koma zamphamvu.Chifukwa chake zinthu zodzaza mu mapulasitiki ndizosavuta kukweza ndi kugwiridwa ndi ogula komanso ogwira ntchito pagulu logawa.Ufulu Wamapangidwe: Makhalidwe azinthu zophatikizidwa ndi umisiri wochulukira wogwiritsidwa ntchito m'makampani, kuyambira jekeseni ndi kuwomba kuumba mpaka thermoforming, zimathandiza kupanga kuchuluka kosawerengeka kwamapaketi ndi masinthidwe.Kuphatikiza apo, mitundu yambiri yamitundu yosiyanasiyana komanso kuphweka kwa kusindikiza ndi kukongoletsa kumathandizira kuzindikira mtundu ndi chidziwitso kwa ogula.
2. Pack for All Seasons Chikhalidwe cha ukadaulo wa mapulasitiki okhala ndi zida zake zambiri zopangira komanso njira zopangira amalola kupanga zopangira mumitundu yosiyanasiyana, mitundu ndi luso laukadaulo.Pafupifupi chilichonse chikhoza kupakidwa mu mapulasitiki - zamadzimadzi, ufa, zolimba ndi zolimba.3.

3.1 Kupaka kwa pulasitiki kumapulumutsa mphamvu Chifukwa ndi mapulasitiki opepuka onyamula amatha kusunga mphamvu ponyamula katundu.Mafuta ochepa amagwiritsidwa ntchito, pali mpweya wochepa ndipo, kuwonjezera apo, pali ndalama zopulumutsa kwa ogulitsa, ogulitsa ndi ogula.
Mphika wa yogati wopangidwa kuchokera ku galasi umalemera pafupifupi 85grams, pamene wopangidwa kuchokera ku pulasitiki umalemera magilamu 5.5 okha.M'galimoto yodzaza ndi zinthu zodzaza mitsuko yamagalasi 36% ya katunduyo amawerengedwa ndi phukusi.Ngati atadzazidwa m'matumba apulasitiki zotengerazo zitha kukhala 3.56%.Kuti anyamule yogati yofananayo pamafunika magalimoto atatu pamiphika yamagalasi, koma miphika iwiri yokha ya pulasitiki.
3.2 Kupaka kwa pulasitiki ndi njira yabwino yogwiritsira ntchito chuma Chifukwa cha kuchuluka kwa mphamvu / kulemera kwa mapulasitiki apulasitiki ndizotheka kulongedza kuchuluka kwazinthu zomwe zaperekedwa ndi mapulasitiki m'malo motengera zinthu zakale.
Zawonetsedwa kuti ngati kulibe mapulasitiki okhala ndi mapulasitiki opezeka kwa anthu ndipo pakadakhala kofunikira kugwiritsa ntchito zida zina zonse zomwe zimagwiritsidwa ntchito ponyamula katundu, mphamvu ndi mpweya wa GHG zitha kuchuluka.3.3 Kuyika kwa pulasitiki kumalepheretsa kuwononga chakudya Pafupifupi 50% yazakudya zonse zomwe zimatayidwa ku UK zimachokera kunyumba zathu.Timataya matani 7.2 miliyoni a chakudya ndi zakumwa m'nyumba zathu chaka chilichonse ku UK, ndipo zoposa theka la izi ndi zakudya ndi zakumwa zomwe tikanatha kudya.Kuwononga chakudyachi kumawononga ndalama zokwana £480 pachaka, kukwera mpaka £680 kwa banja lomwe lili ndi ana, zomwe zimafanana ndi £50 pamwezi.
Kukhalitsa ndi kutsekedwa kwa mapulasitiki oyikapo kumateteza katundu kuti asawonongeke ndikuwonjezera moyo wa alumali.Ndi makonzedwe osinthidwa a mlengalenga opangidwa kuchokera ku mapulasitiki, moyo wa alumali ukhoza kuwonjezeka kuchokera ku 5 mpaka masiku 10, kulola kutaya chakudya m'masitolo kuchepetsedwa kuchokera ku 16% mpaka 4%.Mphesa tsopano zimagulitsidwa m'mathirelo omata kuti zotayirira zikhale ndi mulu.Izi zachepetsa zinyalala m'masitolo nthawi zambiri kuposa 20%.
