Tsanangudzo uye Kusashandisa Zvisizvo
Biodegradable uye compostable inowanzo shandiswa zvakasiyana kutsanangura kuparara kwezvinhu organic mumamiriro chaiwo.Nekudaro, kushandiswa zvisina kunaka kwe "biodegradable" mukushambadzira kwakakonzera kuvhiringidzika pakati pevatengi.Kugadzirisa izvi, BioBag inonyanya kushandisa izwi rekuti "compostable" kune zvigadzirwa zvedu zvakasimbiswa.
Biodegradability
Biodegradability inoreva kugona kwechinhu kuparara kwebiological, kugadzira CO2, H2O, methane, biomass, uye mineral munyu.Ma Microorganisms, anonyanya kudyiswa nemarara, anotyaira maitiro aya.Nekudaro, izwi iri harina kujeka, sezvo zvinhu zvese zvinopedzisira zvaita biodegrade, zvichisimbisa kukosha kwekudoma nharaunda inotarirwa ye biodegradation.
Compostability
Kugadzira manyowa kunosanganisira kugayiwa kwemicrobial kuputsa tsvina yeorganic kuita mufudze, inobatsira pakusimudzira ivhu nekuberekesa.Kupisa kwakanyanya, mvura, uye oxygen mazinga anodiwa pakuita uku.Mumirwi yemarara, utachiona huzhinji hunodya zvinhu, huchichinja kuita manyowa.Kunyorova kwakazara kunoda kuteedzera zviyero zvakaomesesa seEuropean Norm EN 13432 uye US Standard ASTM D6400, kuve nechokwadi chekuora kwakazara pasina zvinokuvadza zvinosara.
International Standards
Kunze kweEuropean Standard EN 13432, nyika dzakasiyana dzine maitiro adzo, kusanganisira US Standard ASTM D6400 uye Australian yakajairwa AS4736.Aya mazinga anoshanda semabhenji evagadziri, masangano anodzora, zvivakwa zvekompositi, masangano ezvitupa, uye vatengi.
Maitiro eCompostable Materials
Zvinoenderana neEuropean Standard EN 13432, compostable zvinhu zvinofanirwa kuratidza:
- Biodegradability yeinenge 90%, ichishandurwa kuita CO2mukati memwedzi mitanhatu.
- Kuparara, zvichikonzera kusakwana kwegumi muzana.
- Kuenderana nekuita komputa.
- Kudzikira kwemasimbi anorema, pasina kukanganisa compost kunaka.
Mhedziso
Biodegradability chete haivimbisi compostability;zvinhu zvinofanirwawo kuparara mukati mechikamu chimwe chekugadzira manyowa.Sezvineiwo, zvinhu izvo zvinomeduka kuita zvisiri-biodegradable zvidiki-zvimedu pane imwechete kutenderera hazvionekwe secompostable.EN 13432 inomiririra yakawiriraniswa tekinoroji chiyero, inoenderana neEuropean Directive 94/62/EC pakurongedza uye kurongedza tsvina.
