Compostable vs. Biodegradable: Kunzwisisa Kusiyanisa

Munyika yanhasi inokoshesa zvakatipoteredza, vatengi vari kuwedzera kutsvaga dzimwe nzira dzekuchengetedza kune zvigadzirwa zvemazuva ese. Matemu akadai se "compostable" uye "biodegradable" anowanzoshandiswa zvakasiyana, asi pane mutsauko wakakosha pakati pezviviri izvi. Kunzwisisa mutsauko kunokupa simba rekuita sarudzo dzine ruzivo dzinoenderana nezvinangwa zvako zveeco-hushamwari.

Biodegradable: A Broad Definition

Biodegradability inoreva kugona kwechinhu kuputsa kuita zvinhu zvakasikwa, kazhinji organic zvinhu, kuburikidza nekuita kwehutachiona. Izvi zvinogona kuitika pasi pemamiriro akasiyana-siyana, kusanganisira mumarara, ivhu, kana mvura.

Nepo biodegradability iri hunhu hwakanaka, haivimbisi kuparara nekukurumidza kana kwezvakatipoteredza. Mwero we biodegradation unogona kusiyanisa zvakanyanya zvichienderana nechinhu, nharaunda, uye kuvapo kweakananga tupukanana. Zvimwe zvinhu zvinoora zvinogona kutora makore kana makumi emakore kuti zviore zvizere.

Compostable: A Specific Standard

Compostability chikamu chakanyanya kuomarara che biodegradability. Compostable zvinhu zvinoputsika kuita organic zvinhu mukati menguva yakatarwa, kazhinji mukati memwedzi mitanhatu kusvika gumi nemiviri, munzvimbo inodzorwa yecompost. Iyi nharaunda, inoratidzwa netembiricha chaiyo, mwando, uye mwero weokisijeni, inogonesa kuita kwehutachiona hunokonzera kuora.

Zvigadzirwa zveCompostable zvinotevedzera zvakamisikidzwa zvakamiswa nemasangano akaita seBiodegradable Products Institute (BPI) muUnited States neEuropean Compostable Packaging Association (ECPA) muEurope. Izvi zvitupa zvinovimbisa kuti zvinhu zvinosanganiswa zvinosangana nemaitiro chaiwo ekuita, anosanganisira biodegradability, kwete-chepfu, uye kusavapo kwezvisaririra zvinokuvadza.

Zvakanakira Compostable Materials

Compostable zvinhu zvinopa akawanda mabhenefiti pane echinyakare zvigadzirwa:

・Yakaderedzwa Kuraswa Marara: Zvinhu zvinoumbwa zvinobvisa marara kubva mumarara, zvichideredza kuremerwa pahurongwa hwekutarisira marara uye kuderedza njodzi yekusvibiswa kwevhu nemvura.

・Kusikwa kweNutrient-Rich Compost: Midziyo inoumbwa inoputsika kuita manyowa ane hupfumi, ayo anogona kushandiswa kusimbisa hutano hwevhu, kutsigira kukura kwechirimwa, uye kuderedza kudiwa kwemafetereza emakemikari.

・Kuchengetedza Zviwanikwa: Zvigadzirwa zvinogadzirwa zvinowanzo shandisa zviwanikwa zvinogoneka, senge zvidyarwa-zvakavakirwa zvinhu, kudzikisira kutsamira pane inopera petroleum reserves.

Kuita Sarudzo Nezivo

・Paunenge uchisarudza pakati pezvigadzirwa zve compostable uye biodegradable, funga zvinotevera zvinhu:

・ Kupedza Kushandisa: Kana chigadzirwa chacho chakagadzirirwa kuita manyowa, sarudza zvinhu zvakasimbiswa zvinogadzirwa. Biodegradable zvinhu zvinogona kusapunzika zvinobudirira munzvimbo dzese dzecompost.

・ Certification: Tsvaga zvigadzirwa zvine zvitupa kubva kumasangano ane mukurumbira seBPI kana ECPA. Izvi zvitupa zvinovimbisa kuti zvinhu zvinosangana necompostability zviyero.

・ Environmental Impact: Funga nezvese kukanganiswa kwezvakatipoteredza kwechigadzirwa, kusanganisira kugadzira, kushandiswa, uye kuraswa. Sarudza zvigadzirwa zvine mashoma ezvakatipoteredza tsoka.

Kugamuchira Mararamiro Akasimba

Kutora zvigadzirwa zvinogoneka uye zvinoora inhanho inoenda kumararamiro akasimba. Nekudaro, zvakakosha kuyeuka kuti zvigadzirwa izvi hazvisi sirivheri yekudzivirira kwezvakatipoteredza. Kuderedza kushandiswa, kushandisazve zvinhu pese pazvinogoneka, uye maitiro ekudzokorodza kwakakodzera zvinoramba zviri zvinhu zvakakosha zvekurarama kwakasimba.

Nekuita sarudzo dzekuziva uye nekumbundikira eco-hushamwari maitiro, isu tinogona pamwe chete kubatsira kupasi rine hutano kwatiri isu nezvizvarwa zvinotevera.
