Haasi ese epurasitiki kurongedza haana hushamwari
Izwi rekuti "plastic" rakanyanya nhasi seshoko rekuti "bepa" raive makore gumi apfuura, anodaro mutungamiri weProAmpac. Plastiki iri zvakare munzira yekuchengetedzwa kwezvakatipoteredza, maererano nekugadzirwa kwezvinhu zvakasvibirira, ipapo kuchengetedza kwezvakatipoteredza kwepurasitiki kunogona kukamurwa kuita.mapurasitiki akadzokororwa, mapurasitiki anogona kuparara, mapurasitiki anodyiwa.
- Mapurasitiki akashandiswa zvakareinoreva zvinhu zvepurasitiki zvakawanikwa zvakare mushure mekugadziriswa kwemarara epurasitiki kuburikidza nekugadzirisa, kunyunguduka granulation, kushandura uye dzimwe nzira dzemuviri kana dzemakemikari, iko kushandiswazve kwepurasitiki.
- Mapurasitiki anopararamapurasitiki ari nyore kuderedzwa mumamiriro echisikigo nekuwedzera humwe huwandu hwezvinowedzera (semu starch, modified starch kana imwe cellulose, photosensitisers, biodegraders, nezvimwewo) mukugadzirwa kwekugadzira, nekuderera kwakadzikama.
- Mapurasitiki anodyiwa, rudzi rwekurongedza kunodyiwa, kureva, kurongedza kunogona kudyiwa, kazhinji kunoumbwa nesitachi, mapuroteni, polysaccharide, mafuta, uye zvinhu zvinoumbwa.
Kurongedza mapepa zvakanyanya kuenderana nemamiriro ekunze?
Kutsiva mabhegi epurasitiki nemabhegi emapepa kwaizoreva kuwedzera kwekuparadzwa kwemasango, izvo zvingave zvakanyanya kudzokera kunzira dzekare dzekunyanya kutema masango. Mukuwedzera pakutemwa kwemiti, kusvibiswa kwepepa kuri nyorewo kufuratirwa, kutaura idi, kushatiswa kwepepa kungave kwakakura kupfuura kugadzirwa kwepurasitiki.
Zvinoenderana nemishumo yenhau, kugadzira mapepa kwakakamurwa kuita nhanho mbiri: kupuruzira uye kugadzira mapepa, uye kusvibiswa kunonyanya kunobva mukuita pulping. Parizvino, ruzhinji rwezvigayo zvemapepa zvinoshandisa nzira yealkaline yekupuruzira, uye patani yega yega yepulp inogadzirwa, matani manomwe emvura nhema achaburitswa, zvichisvibisa mvura inoyerera.
Kunyanya kudzivirira kwezvakatipoteredza ndiko kuderedza kushandiswa kana kushandisazve
Kugadzirwa uye kushandiswa kunoraswa ndiro dambudziko guru rekusvibisa, kuramba "kuraswa", kushandiswa zvakare kune hushamwari. Zviri pachena kuti tose tinofanira kutora matanho kuderedza kukanganisa kwatinoita nharaunda. Kuderedza, shandisazve uye kudzokorodza inzira huru dzekubatsira kuchengetedza nharaunda nhasi. Indasitiri yezvizorwa iri kufambawo yakananga kurongedza kwakasimba kunoderedza, kushandisazve uye kudzokorodza.
