Biodegradable VS Compostable

Chii chinonzi Biodegradable chinorevei?
Biodegradable (Biodegradable) zvinoreva chigadzirwa kana chinhu chinoputsika kuita zvinhu zvakasikwa, carbon dioxide, uye mhute yemvura nezvisikwa zvakaita sebhakitiriya nefungi, izvo zvisingakuvadze nharaunda.

Kazhinji, zvigadzirwa zvinobva muzvirimwa, mhuka, kana zvicherwa zvechisikigo zvinoodza.

Nepo, nehunyanzvi, zvinenge zvese zvinogona kuparara, kunyangwe zvichitora mazana ezviuru zvemakore kuti zvinhu zvakawanda zviparare.

Yakakamurwa Nekunobva Maingredients
Zvinoenderana nekwabva zvinhu zvakabikwa, mapurasitiki anogona kupatsanurwa kuita bio-based biodegradable mapurasitiki uye petrochemical-yakavakirwa biodegradable mapurasitiki.

Pakati pavo, bio-based biodegradable mapurasitiki anogona kukamurwa muzvikamu zvina zvikuru:
1-mapurasitiki akanyatsogadziriswa kubva kune zvakasikwa zvinhu;
2-polymers inowanikwa nekubatana kwekubatana kwe microbial fermentation uye makemikari synthesis;
3-polymers yakanyatsogadzirwa nema microorganisms;
4-biodegradable mapurasitiki anowanikwa nekubatanidza zvinhu izvi kana kusanganisa zvinhu izvi nemamwe mapurasitiki akagadzirwa nemakemikari biodegradable.

Petrochemical-based biodegradable plastics inoreva mapurasitiki anowanikwa ne polymerizing petrochemical monomers nemakemikari synthesis, akadai sePBAT, polybutylene succinate (PBS), carbon dioxide copolymer (PPC), nezvimwewo.

Yakakamurwa neBiodegradation process
Biodegradable mapurasitiki anogona kukamurwa kuita zvachose biodegradable mapurasitiki uye anoparadza biodegradable mapurasitiki.
Mapurasitiki anoparadza biodegradable parizvino anonyanya kusanganisira starch yakagadziridzwa (kana kuzadzwa) polyethylene PE, polypropylene PP, polyvinyl chloride PVC, polystyrene PS zvichingodaro.

Mapurasitiki akazara biodegradable anonyanya kugadzirwa kubva echisikigo macromolecules (senge starch, cellulose, chitin) kana zvekurima uye padivi zvigadzirwa kuburikidza ne microbial fermentation kana synthesis ye biodegradable macromolecules, senge thermoplastic starch mapurasitiki, aliphatic polyesters, uye polylactic acid, Starch/polyvinyl doro, etc. ose mapurasitiki akadaro.

Biodegradable mapurasitiki akavakirwa pazvinhu zvakasikwa zvakaita sestarch parizvino anosanganisira zvinotevera zvigadzirwa: polylactic acid (PLA), polyhydroxyalkanoate (PHA), starch mapurasitiki, bioengineering mapurasitiki, bio-general plastiki (polyolefin uye polychloride) Ethylene).
Polylactic asidhi (PLA)
Natureworks yeUnited States yakaita basa rinoshanda uye rinoshanda mukuvandudza maitiro ekugadzirwa kwepolylactic acid.Yakagadzira kuviriswa kweglucose kubva muchibage kuti ibudise polylactic acid, ine gore negore kugadzirwa kwematani 14,000.Kambani yeJapan yeUNITIKA yakagadzira uye yakagadzira akawanda marudzi ezvigadzirwa, pakati peiyo canvas, matireyi, tableware, nezvimwe zvinoshandiswa zvakanyanya muAichi Expo muJapan.

Kubudirira kweChina ndeye Zhejiang Hisun Biodegradable Plastic Co., Ltd.

Kushandiswa kweiyo biodegradable plastiki
Nekuda kwekuderera kwayo kwakanaka, biodegradable mapurasitiki anonyanya kushandiswa sechikafu chakapfava uye chakaoma chekurongedza zvinhu, inova zvakare yakakura nzvimbo yekushandisa panguva ino.

Misika mikuru inonangwa yemapurasitiki anogona kuparara mabhaisikopo epurasitiki ekurongedza, mafirimu ekurima, mabhegi epurasitiki anoraswa uye midziyo yepurasitiki inoraswa.Kuenzaniswa neyechinyakare epurasitiki kurongedza zvinhu, mutengo wezvinhu zvitsva zvinoparara wakakwira zvishoma.Zvisinei, nekuwedzera kuziva nezvekuchengetedzwa kwezvakatipoteredza, vanhu vanoda kushandisa zvinhu zvitsva zvinoparara nemutengo wakakwirira kuchengetedza zvakatipoteredza.Kuwedzera kuziva nezvekuchengetedzwa kwezvakatipoteredza kwaunza mikana mikuru yebudiriro kuindasitiri inodegradable yezvinhu zvitsva.

Ko Compostable Zvinorevei?
Compostable zvinoreva kuti chigadzirwa chinoputsika kuita zvinhu zvakasikwa, asi munzvimbo yecompost chete.Icho chimiro chebiodegradable chinogona kushandura tsvina yehupenyu (sezvakasara zvekudya nemashizha akadonha) kuita humus, chinhu chakasviba chakasviba chinogona kupa chikafu chakakosha kuvhu.
Compostable zvinhu zvinowanzogadzirwa kubva kuzvirimwa uye zvimwe organic zvinhu, sechibage starch, bagasse, kana PLA (polylactic acid).
Zvichienzaniswa nezvinogadzirwa nebiodegradable, zvinogadzirwa necompost zvine zvimwe zviviri zvinobatsira: zvinokurumidza kuora, zvakawanda zvinoora mumazuva angangoita 90, uye zvakare zvinowora kuita zvigadzirwa zvinovaka muviri zvinogadzira ivhu rine hutano hwepasi.
Zvigadzirwa zveCompostable zvakanaka kune zvakatipoteredza.

Biodegradable VS Compostable
Musiyano uripo pakati pepurasitiki inoomeswa uye compostable zvinhu
Chekutanga, zvese zviri zviviri biodegrable uye compostable zvigadzirwa zviri nani kune nharaunda pane zvechinyakare epurasitiki zvigadzirwa zvinogona kutora mazana emakore kuti zviparare.

Chechipiri, zvese zvinogadzirwa necompostable zvinogona kuomeswa, asi hazvisi zvese biodegradable zvinhu zvinosanganiswa.
Iyo biodegradable zvinhu zvinodzokera kune zvakasikwa uye inogona kunyangarika zvachose, zvisinei, dzimwe nguva inosiya kumashure kwesimbi yakasara.
Zvigadzirwa zvinosungirirwa uye midziyo inosiya humus, iyo inogadzira ivhu rine hutano kuti miti nembesa ikure.
Mune izwi rimwe chete, zvigadzirwa zve compostable zviri biodegradable, asi zvine bhenefiti yakawedzerwa.

Chetatu, Musiyano uripo pakati pezvinokonzeresa uye zvinoomeswa ndewekuti zvigadzirwa zvecompostable zvinoda imwe yakatarwa kana zvivakwa zveindasitiri kuti zviputse, nepo zvigadzirwa zvinoomeswa zvinoputsika zvega.

Kazhinji, composting inzira inokurumidza, kazhinji mukati memazuva makumi mapfumbamwe, asi pasi pemamiriro akakodzera.
Biodegradable plastics zvinoreva mamwe mapurasitiki anogona kuparara kuita kabhoni dhaikisaidhi nemvura munzvimbo yechisikigo, kana mamiriro ekugadzira manyowa, kana mamiriro evhu, kana kuoma kwakakwirira.Iyo yekupedzisira inoda kwete chete zvinhu kuti ive kabhoni dhaibhoni uye mvura, asiwo iyo composting Munguva yekutenderera, mapurasitiki anogona kuita zvidimbu zvidiki zvisingasviki 2cm muhukuru, uye inorema simbi yemukati yemucompost inogadzirwa necompost inofanira kusangana nezviyero. yenyika dzakasiyana-siyana, uye manyowa haazove nemhedzisiro yakaipa pakukura kwezvirimwa zvichienzaniswa necompost yechinyakare.
