Mashanga anogona kucheneswa ari kutoshandiswa munzvimbo zhinji dzakakura dzekupa chikafu panzvimbo yemashanga epurasitiki.Kusimudzirwa nekushandiswa kwemashanga anoora ane kukosha kwakakosha.Parizvino, vanhu vanoziva mashanga, ayo anoshandiswa mumaindasitiri mazhinji akasiyana ekubika.Tichifunga kuti mashanga epurasitiki ari pasi pemamwe matambudziko ezvakatipoteredza uye kutambisa zviwanikwa, vane hanya zvakanyanya nezvikamu zvese.Kutaura zvazviri, mapepa emashanga uyemashanga anoora zvese zviri zviviri zvakatipoteredza zvine hushamwari mumasikirwo, asi mashanga emapepa ari nyore kupfavisa zvinwiwa zvinopisa uyemashanga anoorazvinobatsira zvikuru.

Parizvino, imwe yakanaka yezvakatipoteredza ine hushamwari kune mamwe mashanga epurasitiki inonzi PLA, kana "polylactic acid".Ipurasitiki inogona kubviswa kubva muchibage starch.PLA inogadzirwa kubva kulactic acid, inova iyo mbishi kune yakawanda yechinyakare lactic acid kuvirisa, uye yobva yashandiswa kugadzira PLA.Iyo chaiyo yekugadzira nzira ndeyekupwanya chibage, kubvisa starch kubva mairi, wobva wagadzira isina kucheneswa glucose kubva kune starch, uye wozovirisa iyo glucose nenzira yakafanana nekugadzirwa kwedoro, uye mushure mekunge glucose yaviriswa, inova lactic acid yakafanana chikafu chekuwedzera, uye iyo lactic acid inoshandurwa kuita chigadzirwa chepakati neiyo yakakosha yekumisikidza maitiro kune wega lactic acid.

PLAmashanga anooravane biodegradability yakanaka, kushatisa kunogadzira CO2 neH2O, hapana kusvibiswa kune zvakatipoteredza, uye kunogona kuzadzisa zvinodiwa zveindasitiri composting.Mushure mekuwedzera tembiricha yekupisa, huswa hune hushingi hwekupisa, hwakanaka hwekunyungudutsa, uye kutsvedzerera, kutapurirana mwenje, uye manzwi emaoko anogona kutsiva petroleum-based zvigadzirwa, uye zviratidzo zvemuviri nemakemikari zvezvigadzirwa zvinogona kusangana nezvinodiwa zvekuchengetedza chikafu. pasi rose.Naizvozvo, inoshandiswa zvakanyanya uye inogona kuenderana nezvinodiwa zvezvinwiwa zvakawanda mumusika wazvino.
