Wood-plastic, ʻike ʻia hoʻi ʻo ka lāʻau pale kaiapuni, ka lāʻau plastik a me ka lāʻau no ke aloha, ua kapa ʻia ʻo "WPC" ma ka honua.Hana ʻia ma Iapana i ka hapa ʻelua o ke kenekulia i hala, he ʻano hou ia o nā mea i hana ʻia me ka sawdust, sawdust, bamboo chips, husk, straw wheat hull, soybean hull, peanut shell, bagasse, pulupulu mauʻu a me nā waiwai haʻahaʻa. nā lāʻau biomass.Loaʻa iā ia nā mea maikaʻi o ka fiber mea kanu a me ka plastic, a he ākea ka nui o nā noi, e uhi kokoke ana i nā kahua noi a pau o nā lāʻau, plastics, plastic steel, aluminum alloys a me nā mea like like.I ka manawa like, hoʻoponopono ia i ka pilikia recycling o nā waiwai ʻōpala i nā plastics a me nā ʻoihana lāʻau me ka ʻole o ka pollution.ʻO kāna mau hiʻohiʻona nui: ka hoʻohana ʻana i nā kumu waiwai, ka plasticization o nā huahana, ka mālama ʻana i ke kaiapuni i ka hoʻohana ʻana, ka hoʻokele waiwai, ka hana hou a me ka hana hou.
He ʻāina ʻo Kina me nā kumu waiwai ulu lāʻau ʻilihune, a ʻoi aku ka liʻiliʻi o ka ululāʻau per kapita ma mua o 10m³, akā ua piʻi nui ka ʻai ʻana i ka lāʻau ma Kina.Wahi a nā helu helu, ʻoi aku ka nui o ka ulu ʻana o ka hoʻohana ʻana i ka lāʻau ma Kina ma mua o ka ulu ʻana o GDP, a hiki i ka 423 miliona cubic mika i ka makahiki 2009. Me ka hoʻomohala ʻana i ka hoʻokele waiwai, ua ʻoi aku ka nui o ka nele o ka lāʻau.Ma ka manawa like, ma muli o ka hoʻomaikaʻi ʻana o ka pae hana, nā ʻōpala hoʻoheheʻe lāʻau e like me ka sawdust, shavings, nā kihi kihi a me ka nui o nā mea kanu e like me ka mauʻu, ka ʻōpala raiki a me nā pūpū hua, i hoʻohana ʻia no ka wahie ma ka i ka wā i hala aku nei, ua makehewa loa a loaʻa ka hopena pōʻino i ke kaiapuni.Wahi a nā helu helu, ʻoi aku ka nui o ka ʻōpala ʻōpala i waiho ʻia e ka hana lāʻau ma Kina ma mua o ka miliona miliona i kēlā me kēia makahiki, a ʻo ka nui o nā fila kūlohelohe ʻē aʻe e like me ka ʻōpala raiki he ʻumi miliona mau tona.Eia kekahi, ʻoi aku ka nui o ka noi ʻana o nā huahana plastik me ka hoʻomohala ʻana i ka hoʻokele waiwai, a ʻo ka pilikia o ka "pollution keʻokeʻo" i hoʻokumu ʻia e ka mālama pono ʻole ʻana i ka ʻōpala plastik ua lilo ia i pilikia paʻakikī i ka mālama ʻana i ke kaiapuni.Hōʻike nā ʻikepili noiʻi pili i ka 25%-35% o ka nui o ka ʻōpala o ke kūlanakauhale, a ma Kina, ʻo ka heluna o ke kūlanakauhale o ka makahiki he 2.4-4.8 miliona mau tone o ka ʻōpala.Inā hiki ke hoʻohana maikaʻi ʻia kēia mau mea ʻōpala, e loaʻa ana i nā pono waiwai a me ka pilikanaka.ʻO nā mea lāʻau-plastic kahi mea hou i haku ʻia mai nā mea ʻōpala.
Me ka hoʻoikaika ʻana i ka ʻike o ka poʻe no ka mālama ʻana i ke kaiapuni, ke piʻi nui nei ke kāhea no ka pale ʻana i nā kumulāʻau ululāʻau a me ka hoʻemi ʻana i ka hoʻohana ʻana i ka lāʻau hou.ʻO ka hana hou ʻana i nā lāʻau ʻōpala a me nā plastics me ke kumu kūʻai haʻahaʻa ua lilo ia i mea hopohopo maʻamau i ka ʻoihana a me ka ʻepekema, nāna i hāpai a hāpai i ka noiʻi a me ka hoʻomohala ʻana i nā kumulāʻau lāʻau-plastic composites (WPC), a ua holomua nui, a ua hōʻike pū kāna noi i kahi hoʻomohala wikiwiki. ʻano ʻano.E like me kā mākou i ʻike ai, hiki ke hoʻopau ʻia ka lāʻau ʻōpala a me ka fiber mahiʻai ma mua, a ʻo ka carbon dioxide i hana ʻia he hopena ʻōmaʻomaʻo ma ka honua, no laila ke hoʻāʻo nei nā mea kanu lāʻau e ʻimi i nā ala e hoʻololi ai i nā huahana hou me ka waiwai hoʻohui kiʻekiʻe.Ma ka manawa like, ʻo ka hana hou ʻana i ka plastic ke kumu hoʻomohala koʻikoʻi o ka ʻenehana ʻoihana plastik, a inā hiki ke hana hou ʻia ka plastic a ʻaʻole paha i lilo i kumu koʻikoʻi no ke koho ʻana i nā mea i loko o nā ʻoihana hana plastik.I kēia hihia, ua hoʻokumu ʻia nā mea hoʻohui lāʻau-pulu, a ua nānā nui nā aupuni a me nā keʻena pili a puni ka honua i ka hoʻomohala ʻana a me ka hoʻohana ʻana i kēia mea hoʻonaninani hou.Hoʻohui ka lāʻau-plastic composite i nā pono o ka lāʻau a me ka plastic, ʻaʻole wale ke ʻano e like me ka lāʻau maoli, akā lanakila pū kekahi i kona mau hemahema.Loaʻa iā ia nā pōmaikaʻi o ka pale ʻana i ka corrosion, ka pale ʻana i ka wai, ka pale ʻana i ka moth, ke kūpaʻa kiʻekiʻe kiʻekiʻe, ʻaʻohe māwae a ʻaʻohe warping.He ʻoi aku ka paʻakikī ma mua o ka plastik maʻemaʻe, a he hiki ke hana like me ka lāʻau.Hiki ke ʻoki ʻia a hoʻopaʻa ʻia, hoʻopaʻa ʻia me nā kui a i ʻole nā kī, a pena ʻia.Ma muli o nā pono ʻelua o ke kumukūʻai a me ka hoʻokō ʻana i hoʻonui ʻia nā kumulāʻau lāʻau-plastic composites i kā lākou mau kahua noi a komo i nā mākeke hou i nā makahiki i hala iho nei, e hoʻonui ana i nā mea kuʻuna ʻē aʻe.
Me ka hui pū ʻana o nā ʻaoʻao a pau, ua lele ka pae hana hale o nā mea lāʻau-plastic mea / huahana i ke alo o ka honua, a ua loaʻa iā ia ke kuleana e loaʻa i kahi kūkākūkā like me nā ʻoihana lāʻau-plastic i nā ʻāina hoʻomohala ma ʻEulopa a ʻAmelika.Me ka hoʻoikaika ikaika o ke aupuni a me ka hana hou ʻana i nā manaʻo pilikanaka, e ʻoi aku ka wela a me ka wela o ka ʻoihana lāʻau-pulu i ka wā e ulu ai.He ʻumi kaukani o nā limahana ma ka ʻoihana lāʻau-pulu o Kina, a ʻo ka hana makahiki a me ke kūʻai aku ʻana o nā huahana lāʻau-plastic kokoke i 100,000 tons, me ka waiwai hoʻopuka makahiki ma mua o 800 miliona yuan.Hoʻopili ʻia nā ʻoihana lāʻau-plastic i ka Pearl River Delta a me Yangtze River Delta, a ʻoi aku ka ʻaoʻao hikina ma mua o ka waena a me ke komohana.ʻO ka pae ʻenehana o nā ʻoihana hoʻokahi ma ka hikina ke holomua nei, ʻoiai ʻo nā ʻoihana ma ke kūkulu hema he mau mea maikaʻi loa i ka nui o ka huahana a me ka mākeke.Ua hōʻea a ʻoi aku paha nā hōʻike hōʻike o nā ʻoihana ʻepekema koʻikoʻi a me ka ʻenehana i ka ʻoihana.Ke nānā pono nei kekahi mau ʻoihana nui a me nā hui multinational ma waho o ka ʻoihana i ka hoʻomohala ʻana i ka ʻoihana lāʻau-pulu ma Kina.
