Ma ke ʻano he ʻano hana ʻōpala, pili ka composting i ka hoʻohana ʻana i ka bacteria, actinomycetes, fungi, a me nā microorganism ʻē aʻe i laha nui ʻia ma ke ʻano e hāpai i ka hoʻololi ʻana o nā mea olaola biodegradable i humus paʻa ma ke ʻano hoʻomalu ʻia ma lalo o kekahi mau kūlana hana.ʻO ke kaʻina hana biochemical he kaʻina fermentation.ʻElua mau mea maikaʻi o ka compost: ʻo ka mua, hiki iā ia ke hoʻohuli i nā ʻōpala ʻino i mea maʻalahi, a ʻo ka lua, hiki iā ia ke hana i nā waiwai waiwai a me nā huahana compostable.I kēia manawa, ke ulu wikiwiki nei ka hana ʻōpala honua, a ke piʻi nei hoʻi ke koi no ka mālama ʻana i ka composting.ʻO ka hoʻomaikaʻi ʻana i ka ʻenehana compost a me nā mea hana e hoʻoikaika i ka hoʻomohala mau ʻana o ka ʻoihana compost, a ke hoʻomau nei ka mākeke ʻoihana composting honua.
ʻOi aku ka nui o nā ʻōpala paʻa honua ma mua o 2.2 biliona tons
Ke alakaʻi ʻia nei e ka wikiwiki o ka honua a me ka ulu ʻana o ka heluna kanaka, ke hoʻonui nei ka hoʻomohala ʻōpala paʻa honua i kēlā me kēia makahiki.Wahi a ka ʻikepili i paʻi ʻia ma "WHAT A WASTE 2.0" i hoʻokuʻu ʻia e ka World Bank i ka makahiki 2018, ua hiki i ka honua holoʻokoʻa honua i ka makahiki 2016 i 2.01 biliona Ton, e nānā ana i mua e like me ka wānana wānana i paʻi ʻia ma "WHAT A WASTE 2.0": Proxy hana ʻōpala no kēlā me kēia kapita=1647.41-419.73In(GDP no kēlā me kēia kapita)+29.43 In(GDP per capita)2, me ka hoʻohana ʻana i ka waiwai GDP o kēlā me kēia poʻe honua i hoʻokuʻu ʻia e OECD E like me nā helu ʻana, ua manaʻo ʻia ka hana ʻōpala paʻa honua i ka makahiki 2019. hiki i ka 2.32 biliona tona.
Wahi a ka ʻikepili i hoʻokuʻu ʻia e ka IMF, ʻo ka ulu ʻana o ka GDP honua ma 2020 e -3.27%, a ʻo ka GDP honua ma 2020 e pili ana i ka US $ 85.1 trillion.Ma muli o kēia, ua manaʻo ʻia ʻo ka hana ʻōpala paʻa honua ma 2020 he 2.27 biliona tons.
Papa 1: 2016-2020 hoʻokumu ʻōpala paʻa honua (hui:Bmiliona mau tona)
'Ōlelo Aʻo: ʻAʻole i hoʻokomo ʻia ka nui o nā ʻōpala mahiʻai i ka laulā helu o ka ʻikepili ma luna, e like me lalo.
Wahi a ka ʻikepili i hoʻokuʻu ʻia e “WHAT A WASTE 2.0″, mai ka manaʻo o ka māhele ʻāina o ka hana ʻōpala paʻa honua, ʻo ʻAsia Hikina a me ka ʻāina Pākīpika e hoʻopuka i ka nui loa o ka ʻōpala paʻa, helu no 23% o ka honua, a ukali ʻia e ʻEulopa a me ʻAsia Waena.ʻO ka nui o nā ʻōpala paʻa i hana ʻia ma Asia Hema he 17% o ka honua, a ʻo ka nui o nā ʻōpala paʻa i hana ʻia ma ʻAmelika ʻĀkau he 14% o ka honua.
Papa 2: Ka māhele ʻāina o ka hana ʻōpala paʻa honua (hui: %)

Manaʻo ka nui o ka mākeke ʻoihana composting honua e hoʻokokoke i $ 9 biliona ma 2026
Loaʻa i ka ʻoihana composting honua nā manawa kūpono i ka mahiʻai, ka māla hale, ka hoʻoulu ʻāina, ka horticulture, a me nā ʻoihana kūkulu hale.Wahi a ka ʻikepili i hoʻokuʻu ʻia e Lucintel, ʻo ka nui o ka mākeke ʻoihana composting honua he US $ 6.2 biliona ma 2019.
