Sei kushandisa mapurasitiki anoodegradable?
Plastiki chinhu chakakosha chakakosha. Nekukurumidza kusimukira kwehupfumi uye nzanga uye kubuda kwenhamba huru yemaindasitiri matsva senge e-commerce, kuburitsa pachena uye kutora, kudyiwa kwezvigadzirwa zvepurasitiki kuri kukwira nekukurumidza.
Plastiki haingounzi hupenyu hwevanhu chete, asiwo inokonzera "kusvibiswa chena", iyo inokuvadza zvakanyanya nharaunda uye hutano hwevanhu.
China yakaisa pachena chinangwa chekuvaka China yakanaka, uye kutonga kwe "kusvibiswa kwakachena" ndiko kudiwa kwekuvandudza hutano hwezvakatipoteredza uye kuvaka China yakanaka.
Chii chinonzi biodegradable plastics?
Mapurasitiki anoshatisa mapurasitiki anoshatiswa nekuita kwehutachiona muzvisikwa, senge ivhu, ivhu rejecha, nharaunda yemvura yakachena, nharaunda yemvura yegungwa uye mamiriro chaiwo akadai secomposting kana anaerobic digestion, uye pakupedzisira yakaderedzwa zvachose kuita kabhoni dioxide (CO2) kana / uye methane (CH4), mvura (H2O) uye mineralized inorganic salts yezvinhu zvavo, pamwe chete ne biomass itsva (senge ma microorganisms akafa, nezvimwewo).
Ndeapi mapoka emapurasitiki anoparara?
Zvinoenderana neiyo Standard Guide for Classification uye kunyora mazita ezvigadzirwa zvepurasitiki zvinoparara zvakarongwa neChina Federation of Light Indasitiri, mapurasitiki anoparara ane maitiro akasiyana ekusvibisa muvhu, manyowa, nyanza, mvura yakachena (nzizi, nzizi, madziva) nedzimwe nharaunda.
Zvinoenderana neakasiyana mamiriro ezvakatipoteredza, mapurasitiki anoparara anogona kukamurwa kuita:
Ivhu rinoora mapurasitiki, composting mapurasitiki anoora, mvura yakachena nharaunda mapurasitiki anoshatisa, sludge anaerobic digestion mapurasitiki anoora, akakwirira akasimba anaerobic digestion mapurasitiki anoora.
Ndeupi mutsauko uripo pakati pemapurasitiki anoparara nemapurasitiki akajairwa (asina-kuora)?
Mapurasitiki echinyakare anonyanya kugadzirwa nepolystyrene, polypropylene, polyvinyl chloride uye mamwe mapolymer makomisheni ane huremu hwemamorekuru emazana ezviuru uye yakagadzika chimiro chemakemikari, izvo zvakaoma kuderedzwa nema microorganisms.
Zvinotora makore 200 nemakore mazana mana kuti mapurasitiki echinyakare adzikise munzvimbo yechisikigo, saka zviri nyore kukonzera kusvibiswa kwezvakatipoteredza nekurasa mapurasitiki echinyakare pamadiro.
Biodegradable mapurasitiki akasiyana chaizvo nemapurasitiki echinyakare mumakemikari chimiro. maketani avo epolymer makuru ane nhamba huru ye ester bond, iyo inogona kugayiwa uye kushandiswa ne microorganisms, uye pakupedzisira yakaora kuita mamorekuru madiki, ayo asingazokonzerese kusvibiswa kusingaperi kune zvakatipoteredza.
Mabhegi epurasitiki ane hushamwari kwezvakatipoteredza pamusika anogona kuparara here?
Zvinoenderana nezvinodiwa zvekunyora zveGB/T 38082-2019 "Biodegradable plastic Shopping mabhegi", zvichienderana nekushandiswa kwakasiyana kwemabhegi ekutenga, mabhegi ekutenga anofanirwa kunyorwa zvakajeka "chikafu chakanangana nemabhegi epurasitiki ekutenga" kana "asiri chikafu chakananga kuonana." biodegradable plastic shopping bags”. Iko hakuna "hushamwari hwepurasitiki bag" logo.
Iwo ekudzivirira kwezvakatipoteredza epurasitiki mabhegi pamusika mamwe magimmicks akagadzirwa nemabhizinesi muzita rekuchengetedza kwezvakatipoteredza. Ndapota svinura meso ako uye sarudza nokungwarira.
