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 kuora nebhakitiriya kana zvimwe zvipenyu, uye "compost" muindasitiri yepurasitiki inotsanangurwa sekugona kuparara munzvimbo ine aerobic inochengetwa panguva chaiyo. controlled tembiricha uye mwando mamiriro ezvinhu.Compospost kugona kuodza zvipenyu mumunda wecompost, zvichiita kuti zvinhu zvisaonekwe uye zviore kuita carbon dioxide, mvura, inorganic compounds uye biomass pamwero unoenderana
Kusanganisirwa kwe "inorganic material" kwakabvisa chigadzirwa chekupedzisira kubva pakuonekwa secompost kana humus, inova organic material chete.Muchokwadi, xxx standard inodiwa kuti plastiki idaidzwe compost pasi petsanangudzo yeASTM ndeyekuti inofanirwa kunyangarika panguva imwe chete. chiyero sechimwe chinhu icho munhu anotoziva kuita compost pasi petsanangudzo yechinyakare. 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 chine mashiripiti," kunyangwe izwi iri richishandiswa zvakanyanya, sekureva kwaRamaniNarayan, injiniya wemakemikari paEast Lansing Michigan State University uye nyanzvi yesainzi kuInstitute for Biodegradable Plastics. "Ichi ndicho chinonyanya kushandiswa uye izwi rakashandiswa zvisizvo muduramanzwi redu.Munzvimbo yeGreater Pacific Waste Area, plastiki inoora inoputsika kuita zvidimbu zvidiki zvinokwanisa kupinda nyore mucheni yechikafu nekudyiwa.
4.Kudzokororwa kwemabhegi anoodegradable.
Marara ari muchirimwa anogona kazhinji kudzokororwa, asi zvakaoma kuronga uye kudzokorodza mushure mekushandiswa.Bio-based polymers inogona kusvibisa kudzokororwa kwemamwe mapolymers akajairika.Apo vagadziri ve aerobic biodegradable plastics vachiti mabhegi avo anogona kushandiswa zvakare, akawanda epurasitiki mafirimu. vanodzokororazve havazozvigamuchire nekuti hapana chidzidzo chenguva refu pamusoro pekugoneka kwezvinhu zvinogona kudzokororwa zvine izvi zvinowedzera.Pakuwedzera, iyo Institute for Biodegradable Plastics (BPI) yakataura kuti magadzirirwo ezvekuwedzera mumafirimu ane oxidized anosiyana zvakanyanya, izvo zvinounza kuwedzera kusiyanisa. mukugadzirisa zvakare.
