Zida zotayidwa za biodegradable tableware zitha kukhala zachilendo mtsogolo

Mu 1986, thovu tableware anayamba kugwiritsidwa ntchito pa njanji China. Kumayambiriro kwa zaka za m'ma 2100, mabokosi a thovu a nkhomaliro anali atakhala zida zotayirapo. Pali zovuta zazikulu pakupanga, kugwiritsa ntchito ndi kubwezeretsanso zinthu zotayidwa thovu. Zinthu zina zotulutsa thovu zomwe zimagwiritsidwa ntchito popanga zimawononga ozoni wa mumlengalenga, ndipo zina zimakhala ndi zoopsa zobisika; kugwiritsa ntchito molakwika pa kutentha kwambiri kumatha kupanga mosavuta zinthu zovulaza thanzi la munthu; kutaya mosasamala mukatha kugwiritsa ntchito kungayambitse kuwononga chilengedwe; kukwiriridwa m'nthaka kungayambitse kuwonongeka kwakukulu kwa chilengedwe. Ndizovuta kutsitsa, kuwononga dothi ndi madzi apansi, ndipo ndikovuta kukonzanso. Zakumwa zotayidwa za thovu zinaletsedwa pambuyo pake.

Cha m'ma 2003, ena opanga zoweta anayamba kukhazikitsa PP jakisoni kuumbidwa tableware disposable. Ambiri aiwo amagwiritsa ntchito zisankho zamakina zochokera kunja. M'masiku oyambirira, kugulitsa kunja kunali msika waukulu. Ndi chitukuko cha intaneti komanso kukwera kwa nsanja zotengerako, mabokosi a PP masana pang'onopang'ono awonetsa zofooka zawo. Zitha kusefukira ndipo sizimatsekeredwa pamayendedwe. Kutaya mwachisawawa mabokosi a PP nkhomaliro kungayambitsenso kuipitsa kwakukulu kwa chilengedwe; nzovuta kunyozetsa pamene akwiriridwa m'nthaka. Pansi pa ndondomeko ya "pulasitiki yoletsa / kuletsa", mabokosi a nkhomaliro ngati amenewa akufunafunanso zotsogola ndikukula njira yoteteza chilengedwe.

Chitukuko cha dziko langa zamkati akamaumba makampani anayamba m'ma 1980 ndipo unatha mpaka 2000. Iwo nthawizonse anali atangoyamba kumene. Mu 2001, dziko langa linalowa m’bungwe la World Trade Organization. Mabizinesi akuumba zamkati zamkati adakula mwachangu, ndipo njira yopangira, ukadaulo ndi zida zidayamba mawonekedwe atsopano. Mitundu yosiyanasiyana yazinthu zopangidwa ndi zamkati zimawonekera. Kuyambira 2020, mfundo ya dziko langa ya "kuletsa / kuletsa pulasitiki" yakhala ikugwiritsidwa ntchito pang'onopang'ono, ndipo makampani owumba zamkati akhala akukula mwachangu kuyambira 2020.

The zopangira za zamkati kuumbidwa mankhwala zimachokera osiyanasiyana magwero, ndipo ambiri mwa zipangizo zazikulu zopangira ulusi zomera zitsamba, monga mabango, udzu wa tirigu, udzu wa mpunga, bagasse, nsungwi, etc. Pakali pano, zoweta zamkati mphero kuti gwiritsani ntchito bango, bagasse, nsungwi, udzu wa tirigu ndi ulusi wina wa udzu popeza zida zazikulu zili ndi machitidwe awoawo oletsa kuwononga chilengedwe. Pankhani ya zopangira, mapepala opangidwa ndi mapepala ayamba kale kutsata njira ya "centralized pulping and decentralized production", osati kokha kuti alibe mavuto owononga chilengedwe, komanso amatha kupeza zitsimikizo zodalirika zakuthupi. Pakati pawo, nsungwi ndizinthu zabwino kwambiri zopangira. Nsungwi imakula msanga, ilibe zotsalira za mankhwala ophera tizilombo ndi feteleza, ndipo imakhala ndi fungo lachilengedwe. Bamboo ndi chinthu chongowonjezedwanso, chopangidwa ndi kompositi chomwe chimakhala ndi ntchito zosiyanasiyana pakuyika.

Ukadaulo wopangira zinthu zopangidwa ndi zamkati ndi wosavuta, ndipo palibe magwero oipitsa panthawi yopanga, zomwe zimakwaniritsa zofunikira pakupanga zachilengedwe. Kuphatikiza apo, zida zopangira zamkati zimapangidwira kwambiri m'nyumba, zomwe zimathandiza kwambiri pakukweza polojekiti ndikugwiritsa ntchito.

Zogulitsa zopangidwa ndi ma Pulp zimakhala ndi ntchito zosiyanasiyana, msika wawukulu, komanso kuthekera kochulukira komwe kungagulidwe. Zogulitsa zawo zitha kugwiritsidwa ntchito kwambiri pakuyika zida zamagetsi, kubzala ndi kulima mbande, ziwiya zamankhwala, ziwiya zodyera, ndi zomangira zosalimba. Zamkati zogwirizana Mzere wopangira umatha kupanga zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito mosiyanasiyana pongowongolera ndikusintha zisankho. Ntchito zake zosiyanasiyana komanso kubwezeredwanso kumapangitsa kuti zinthu zina zofananira zizifanana.

Pulp molded tableware ndi nthambi yofunikira yazinthu zopangidwa ndi zamkati. Ndi yosavuta kukonzanso, ikhoza kugwiritsidwanso ntchito, ndipo imadziwononga yokha. Zimachokera ku chilengedwe ndikubwerera ku chilengedwe. Ndi chinthu chosaipitsa, chonyozeka, chobiriwira komanso chokonda zachilengedwe, chomwe chimagwirizana kwambiri ndi masiku ano. Kufunika kogwiritsa ntchito zinthu zopangidwa ndi zamkati sikungothandiza kupulumutsa chilengedwe komanso kuchepetsa kusintha kwa nyengo, komanso kumawonjezera moyo wamunthu.

Pamene kuzindikira kwa anthu za kuteteza chilengedwe ndi thanzi kukupitiriza kulimbikitsa, tableware wochezeka zachilengedwe adzatha m'malo mwachikhalidwe disposable pulasitiki tableware m'tsogolo.
