Ka nānā 'ana i nā huahana plastic o kā mākou hui
Nui nā ʻano o ka plastic, a ʻo kā mākou hui he mea hana i nā ipu plastik no nā mea hoʻonaninani, ʻoihana, nā mea uila, nā mea pāʻani puhi ʻia, nā waiwai i hoʻohana ʻia i kēlā me kēia lā e hoʻohui i ka hoʻomohala ʻana, hoʻolālā a kūʻai aku. nā huahana plastik ʻē aʻe. Aia i loko o ka hoʻokele waiwai i kūkulu ʻia ʻo Pearl River Delta,hauʻoli mākou i ka lawe ʻana i ka ʻāina a me ka wai, hoʻopaʻa i nā lako hana kiʻekiʻe egplastic molding machines, ʻōmole puhi mīkini, ʻakomi pale paʻi, gilding machines, a ua hoonui i ka unahi hana.
