SINGAPORE: Manaʻo paha ʻoe he maikaʻi ka hoʻololi ʻana mai nā plastic plastic biodegradable no ke kaiapuni akā ma Singapore, ʻaʻohe "ʻokoʻa kūpono", wahi a nā loea.
Hoʻopau pinepine lākou ma kahi hoʻokahi - ʻo ka mea hoʻolalelale, wahi a Associate Professor Tong Yen Wah mai ke Keʻena ʻOihana Kimia a me Biomolecular Engineering ma ka National University of Singapore (NUS).
Hoʻololi ʻia nā ʻōpala plastik biodegradable i ke kaiapuni i ka wā i kanu ʻia ai lākou i loko o nā pae ʻāina, ua hoʻohui ʻo ia.
"I kēia mau kūlana, hiki i kēia mau ʻeke plastik ke hoʻohaʻahaʻa wikiwiki i ka hoʻohālikelike ʻia me kahi ʻeke plastik polyethylene maʻamau a ʻaʻole e hoʻopilikia nui i ke kaiapuni.ʻO ka holoʻokoʻa no Singapore, ʻoi aku ka maikaʻi o ka hoʻopau ʻana i nā plastic biodegradable, "wahi a Assoc Prof Tong.Ua wehewehe ʻo ia no ka mea ʻo kekahi mau koho biodegradable e lawe i nā kumuwaiwai hou aʻe e hana ai, ʻoi aku ka nui o ke kumukūʻai.
Ua like ka manaʻo me ka mea a Dr Amy Khor, ke Kuhina Nui o ka Moku'āina no ka Environment a me nā Waiwai Wai i ʻōlelo ʻia i loko o ka Pāremata i ʻAukake - ua ʻike ʻia kahi loiloi ola o nā ʻeke lawe hoʻohana hoʻokahi a me nā mea hoʻohana e ka National Environment Agency (NEA) ʻO nā plastics me nā ʻano mea hoʻohana hoʻokahi hoʻohana ʻia ʻaʻole "ʻoi aku ka maikaʻi no ke kaiapuni".
“Ma Singapore, ua hoʻopau ʻia ka ʻōpala a ʻaʻole waiho ʻia i loko o nā ʻāina e hoʻohaʻahaʻa.ʻO ia ke ʻano o nā koi waiwai o nā ʻeke hiki ke hoʻoheheʻe ʻia e like me nā ʻeke plastik, a loaʻa pū kekahi i ka hopena o ke kaiapuni ke puhi ʻia.
"Eia kekahi, hiki i nā ʻeke oxo-degradable ke hoʻopilikia i ke kaʻina hana hou i ka wā i hui pū ʻia me nā plastics maʻamau," wahi a ka noiʻi NEA.
Māhele koke nā plastics hiki ke hoʻoheheʻe ʻia i nā ʻāpana liʻiliʻi a liʻiliʻi, i kapa ʻia ʻo microplastics, akā ʻaʻole e wāwahi i ka pae molekala a i ʻole polymer e like me nā plastic biodegradable a compostable.
Ua waiho ʻia nā microplastics i ke kaiapuni no ka manawa pau ʻole a hiki i ka wā e haki ai.
Ua hoʻoholo ʻo European Union (EU) i Malaki e pāpā i nā mea i hana ʻia me ka plastic oxo-degradable me ka pāpā ʻana i nā plastics hoʻohana hoʻokahi.
I ka hoʻoholo ʻana, ua ʻōlelo ka EU "ʻaʻole pono biodegrade a no laila ke hāʻawi nei i ka pollution microplastic i ke kaiapuni".
Ka manawa hoʻouna: Dec-22-2023
