Kodi zobiriwira zoteteza zachilengedwe ndi chiyani?
Zipangizo zobiriwira komanso zoteteza chilengedwe zimatchula zinthu zomwe zimakumana ndi Life Cycle Assessment popanga, kugwiritsa ntchito, ndi kukonzanso zinthu, ndizosavuta kuti anthu azigwiritsa ntchito komanso sizikuwononga chilengedwe, ndipo zimatha kuonongeka kapena kubwezeretsedwanso akagwiritsidwa ntchito.
Pakalipano, zida zolongedza zomwe zimagwiritsidwa ntchito kwambiri zobiriwira komanso zachilengedwe zimaphatikizirapo: zida zamapepala, zida zachilengedwe, zowonongeka, ndi zinthu zodyedwa.
1.Paper zipangizo
Zida zamapepala zimachokera kuzinthu zachilengedwe zamatabwa ndipo zimakhala ndi ubwino wowonongeka mofulumira komanso zosavuta kuzibwezeretsanso. Ndiwopakapaka wobiriwira wodziwika kwambiri wokhala ndi mawonekedwe otambalala kwambiri komanso nthawi yogwiritsidwa ntchito koyambirira ku China. Oimira ake makamaka amaphatikizapo mapepala a zisa, kuumba zamkati ndi zina zotero.
Pambuyo popaka mapepala akugwiritsidwa ntchito, sizidzangoyambitsa kuipitsa ndi kuwonongeka kwa chilengedwe, koma zikhoza kuchepetsedwa kukhala zakudya. Chifukwa chake, mumpikisano wowopsa wamasiku ano wazolongedza, mapepala opangira mapepala akadali ndi malo pamsika, ngakhale amakhudzidwa ndi zinthu zapulasitiki ndi zinthu za thovu.
Kupaka kwa "zakudya zam'mapepala" kuchokera ku Australia, ngakhale supuni imapangidwa ndi zamkati!
2. Natural biological ma CD zipangizo
Zida zachilengedwe zomangira zachilengedwe zimaphatikizanso zinthu zopangira ulusi wa zomera ndi zowuma, zomwe ulusi wachilengedwe wachilengedwe umaposa 80%, womwe uli ndi zabwino zomwe sizingawononge komanso zongowonjezedwanso. Pambuyo pa ntchito, imatha kusinthidwa kukhala michere, ndikuzindikira kuzungulira kwachilengedwe kuchokera ku chilengedwe kupita ku chilengedwe.
Zomera zina ndi zinthu zachilengedwe zopangira ma CD, zomwe zimatha kukhala zobiriwira komanso zatsopano ndikuwongolera pang'ono, monga masamba, mabango, mphira, machubu ansungwi, ndi zina. Maonekedwe okongola ndi mwayi wawung'ono wa ma CD amtunduwu omwe sakuyenera kutchulidwa. Chofunika kwambiri, itha kulolanso kuti anthu adziwe bwino za chilengedwe choyambirira!

3. Zida zowonongeka
Zida zowonongeka zimakhala makamaka pamaziko a pulasitiki, kuwonjezera photosensitizer, wowuma wosinthidwa, biodegradant ndi zipangizo zina. Ndipo kupyolera mu zipangizozi kuchepetsa kukhazikika kwa mapulasitiki achikhalidwe, kufulumizitsa kuwonongeka kwawo m'chilengedwe, kuti achepetse kuipitsidwa kwa chilengedwe.
Pakalipano, okhwima kwambiri makamaka ndi zipangizo zowonongeka, monga wowuma, polylactic acid, filimu ya PVA, etc. Zida zina zatsopano zowonongeka, monga mapadi, chitosan, mapuloteni, ndi zina zotero zimakhalanso ndi mwayi waukulu wa chitukuko.

4. Zida zodyera
Zinthu zodyedwa zimapangidwa makamaka ndi zinthu zomwe zimatha kudyedwa mwachindunji kapena kulowetsedwa ndi thupi la munthu, monga lipids, ulusi, wowuma, mapuloteni, ndi zina zambiri. . Komabe, chifukwa ndi chakudya chamagulu ndipo chimafunikira ukhondo wokhazikika panthawi yopanga, mtengo wake wopangira ndi wokwera kwambiri ndipo siwoyenera kugwiritsidwa ntchito pamalonda.
Kuchokera pamalingaliro a zotengera zobiriwira, chisankho chomwe chimakondedwa kwambiri sichonyamula kapena kulongedza pang'ono, chomwe chimathetsa zovuta za kulongedza chilengedwe; Chachiwiri ndi chobweza, choyikanso chogwiritsidwanso ntchito kapena choyikanso, chobwezeretsanso bwino komanso zotsatira zake zimadalira njira yobwezeretsanso komanso lingaliro la ogula.
Pakati pa zida zopangira zobiriwira, "mapaketi owonongeka" akukhala m'tsogolo. Ndi "chiletso cha pulasitiki" chokwanira, matumba ogula apulasitiki osawonongeka adaletsedwa, msika wowonongeka wapulasitiki ndi mapepala adalowa munthawi yaphulika.
Chifukwa chake, pokhapokha anthu ndi mabizinesi atenga nawo gawo pakukonzanso zobiriwira zochepetsera pulasitiki ndi kaboni pomwe nyenyezi yathu yabuluu imatha kukhala yabwinoko.
5. Kraft kulongedza
Matumba a Kraft sakhala ndi poizoni, alibe vuto, komanso alibe kuipitsa. Amakwaniritsa miyezo yadziko lonse yoteteza zachilengedwe. Iwo ndi amphamvu kwambiri komanso okonda zachilengedwe. Pakali pano ndi imodzi mwazolemba zodziwika bwino padziko lonse lapansi.
Pepala la Kraft limachokera pamapepala onse amatabwa. Mtunduwo umagawidwa kukhala pepala loyera la kraft ndi pepala lachikasu la kraft. Kanemayo amatha kuphimbidwa ndi zinthu za PP pamapepala kuti agwire ntchito yosalowa madzi. Mphamvu ya thumba ikhoza kupangidwa kukhala imodzi kapena isanu ndi umodzi malinga ndi zofuna za makasitomala. Kuphatikiza kusindikiza ndi kupanga thumba. Njira zotsegula ndi kumbuyo zimagawidwa kukhala kusindikiza kutentha, kusindikiza mapepala ndi pansi pa nyanja.
Monga tonse tikudziwa, pepala la kraft ndi chinthu chobwezerezedwanso. Zida zopangira mapepala zimakhala makamaka ulusi wa zomera. Kuphatikiza pa zigawo zitatu zazikulu za cellulose, hemicellulose, ndi lignin, zopangirazo zimakhalanso ndi zigawo zina zomwe zili ndi zinthu zochepa, monga utomoni ndi phulusa. Kuonjezera apo, pali zowonjezera zowonjezera monga sodium sulfate. Kuphatikiza pa ulusi wobzala pamapepala, zodzaza zosiyanasiyana zimafunikira kuwonjezeredwa malinga ndi zida zosiyanasiyana zamapepala.
Pakadali pano, zida zopangira mapepala a kraft makamaka mitengo ndi kubweza mapepala otayidwa, zomwe zonse ndizongongowonjezwdwa. Makhalidwe a kuwonongeka ndi kubwezeretsedwanso amalembedwa mwachibadwa ndi zolemba zobiriwira.
Zambiri zitha kupezeka mukalozera wazinthu
