Biodegradable uye inoshamisira

Tsanangudzo uye Kushandisa zvisizvo

Biodegradable uye compostable inowanzoshandiswa ichichinjika kurondedzera kuputsika kwezvinhu zvemagetsi mumamiriro ezvinhu. Nekudaro, kushandisa zvisina kufanira kwe "biodegradable" mukushambadzira kwakaita kuti vanyonganiswe pakati pevatengi. Kugadzirisa izvi, biobag kunyanya anoshandisa izwi rekuti "zvinoshamisa" zvezvinhu zvedu zvakasimbiswa.

Biodegradability

Biodergradability inoreva kugona kwezvinhu zvekusvibiswa biological kusvibiswa, kubereka co₂, H₂O, methane, biomass, uye mineral munyu. Microorganisms, kunyanya inodyiswa nemarara organic, driver ichi maitiro. Nekudaro, izwi iri rinoshaya chokwadi, sezvinoita zvese zvinopedza biodegrade, uchisimbisa kukosha kwekutsanangura zvakatemerwa nzvimbo ye biodegradation.

Comostability

Compostion inosanganisira microbial kugaya kuti ubvise marara embiru kuita marara mune compost, inobatsira kuvandudza kwevhu uye kusimbisa. Kupisa kwakaipa, mvura, uye mwekadzi mazinga anodikanwa kuti izvi zviite. Mumadziro emarara ashatirwi, micritrad mauto anodya zvinhu, achivashandura kuita compost. Kuzere Compentability kunoda kuomerera kumanje mitezo yakadai seEuropean Norg En 13432 uye US Standard ASTM D6400, inoona kuora kwakazara pasina zvinokuvadza pasina.

NYAYA YENYAYA

Kunze kweEuropean Standard en 13432, nyika dzakasiyana siyana dzine zvavaiita, kusanganisira US Standard ASTM D6400 uye Australia Norm ASTH AS4736. Izvi zviyero zvinoshanda seBenchmarks kune vagadziri, miviri yekuzvimiririra, nzvimbo dzinovhiringidza, masangano ezvitambi, uye vatengi.

Maitiro ezvishandiso zvinoshamisa

Zvinoenderana neEuropean Standard en 13432, zvinhu zvinokonzeresa zvinofanirwa kuratidza:

• Biodegradability yeanenge 90%, inoshandura mu co₂mukati memwedzi mitanhatu.
• Kupararira, kuchikonzera kusingasviki 10% zvakasara.
• Kuenderana neyakagadzirirwa nzira.
• Mwero wakaderera wemasimbi anorema, pasina kukanganisa compost mhando.

Mhedziso

Biodegradability yega haisimbisi composteability; Zvigadzirwa zvinofanirwawo kupaza mukati meimwe danho rekutenderera rimwe chete. Zvekare, zvigadzirwa izvo zvidimbu zviri muzvikamu zvisiri zve biodeble micro-zvidimbu pamusoro pekutenderera kumwe chete hazvigone kutariswa zvakaringana. En 13432 inomiririra nzira yekuwirirana
