Pulasitiki ili paliponse.Chaka chilichonse matani oposa 300 miliyoni amapangidwa.Kupanga pulasitiki padziko lonse lapansi kwachulukirachulukira ka 20 kuyambira 1950, ndipo akuyembekezeka kuwirikiza katatu pofika 2050.
N’zosadabwitsa kuti zimenezi zikuchititsa kuti pakhale kuipitsidwa kwakukulu kwa pulasitiki m’nyanja ndi pamtunda.Kusintha ndikofunikira mwachangu.Koma kwa mabizinesi ambiri ndi magulu ogula zinthu, kumvetsetsa kuti ndi zida ziti zonyamula zomwe ndizochezeka kwambiri pazachilengedwe chawo si ntchito yosavuta.
Ngati mwakhala mukuyang'ana pazakudya zokhazikika komanso zongowonjezwdwa, mwina mudamvapo za fiber.Zopangira zopangira chakudya cha fiber ndi zina mwazosankha zomwe sizimakonda zachilengedwe kunjaku.Zopangira zopangira ma fiber ndizokhazikika komanso zofananira ndi zinthu zachikhalidwe pazantchito komanso zokongoletsa.
Kupaka kwa fiber kumapangidwa ndi zinthu zomwe zimatha kugwiritsidwanso ntchito, zongowonjezedwanso, kapena zowonongeka.Amagwiritsidwa ntchito makamaka m'mafakitale omanga, mankhwala, chakudya ndi zakumwa.Kupaka kwa fiber kumatha kupangidwa kuchokera kuzinthu zosiyanasiyana.Izi zimaphatikizapo zinthu zobwezerezedwanso (monga nyuzipepala ndi makatoni) kapena ulusi wachilengedwe monga zamkati zamatabwa, nsungwi, bagasse, ndi udzu wa tirigu, zidazi zimagwiritsa ntchito mphamvu zochepera 10 kupanga kuposa zida zamitengo ndipo ndizosankha zachilengedwe.
Zhiben Environmental Protection Technology Group ndiyomwe imayang'ana kwambiri mabizinesi ogwiritsira ntchito ulusi wa zomera ndi zinthu zake zabwino kwambiri.Timapereka mayankho athunthu pakuperekera zinthu zopangira, Bio-pulping, makonda a zida, kapangidwe ka nkhungu, kukonza, ndi kupanga zochuluka ndikukwaniritsa zogulitsa-kutumiza, kutumiza, ndi ntchito zogulitsa pambuyo pake.
