1.Biodegradation bag，Mabhegi eBiodegradation mabhegi anokwanisa kuodzwa nemabhakitiriya kana zvimwe zvipenyu.About 500 bhiriyoni kusvika 1 trillion masaga epurasitiki anoshandiswa gore rega rega. Mabhegi eBiodegradation masaga anokwanisa kuodzwa nemabhakitiriya kana zvimwe zvipenyu.Mabhegi epurasitiki anoda kusvika 500 bhiriyoni kusvika trillion anoshandiswa gore rega rega.
2.Kusiyanisa pakati pe "biodegradable" uye "compostable"
Muchidimbu, izwi rekuti biodegradable rine chirevo chakasiyana pane compost.Biodegradable inongoreva kuti zvinhu zvinogona kuparara nebhakitiriya kana zvimwe zvipenyu, uye "compost" muindasitiri yepurasitiki inotsanangurwa sekugona kuparara munzvimbo ine aerobic inochengetedzwa pane chaiyo inodzorwa tembiricha uye mwando mamiriro. mvura, inorganic compounds uye biomass pamwero unowirirana
Iko kuiswa kwe "inorganic material" kwakabvisa chigadzirwa chekupedzisira kubva pakuonekwa semupfudze kana humus, iyo inongove yakasikwa. Mabhegi epurasitiki anogona kugadzirwa kubva kune akajairwa epurasitiki polymer (kureva, polyethylene) kana polypropylene uye yakasanganiswa nekuwedzera iyo inokonzeresa kuparara kwepolymer (polyethylene) uyezve biodegradable nekuda kwe.
3.Material for the biodegradable bag
yakasimba seyakasimba uye yakavimbika seyechinyakare (kunyanya polyethylene) mabhegi.Mabhegi mazhinji anogadzirwawo nemapepa, organic materials, kana polyhexanolactone. "Veruzhinji vanoona biodegradable chinhu chemashiripiti," kunyangwe izwi iri richishandiswa zvakanyanya, sekureva kwaRamaniNarayan, injiniya wemakemikari paEast Lansing Michigan State University uye nyanzvi yezvesainzi kuInstitute for Biodegradable Plastics." Iri ndiro izwi rinonyanya kushandiswa uye rinoshandiswa zvisizvo muduramazwi redu.
4.Kudzokororwa kwemabhegi anoodegradable.
In-plant tsvina inogona kuwanzoshandiswa zvakare, asi zvakaoma kuronga uye kushandiswazve mushure mekushandiswa.Bio-based polymers inogona kusvibisa kushandiswa kwemamwe mapolymers anowanzozivikanwa.Kunyange zvazvo vagadziri ve aerobic biodegradable plastiki vanoti mabhegi avo anogona kushandiswa zvakare, akawanda epurasitiki mafirimu recyclers haazoagamuchiri nokuti hapana chidzidzo chenguva refu pamusoro pekugoneka kwezvigadziriswa zveBiograd zvinogadzirwa nePlastic Institute. (BPI) yakataura kuti magadzirirwo ezvekuwedzera mumafirimu ane oxidized anosiyana zvakanyanya, izvo zvinounza kusiyanisa kwakawanda mukudzokorodza maitiro.
