Ua hoʻololi ka cigarette i ka ʻeke plastik biodegradable ma India.
ʻO ka pāpā ʻana o India i 19 mau mea hoʻohana hoʻokahi i hoʻololi i kāna ʻoihana paka. Ma mua o Iulai 1, ua hoʻololi ka poʻe hana kikaki India i kā lākou ʻeke plastik maʻamau ma mua i ka ʻeke plastik biodegradable. Ua ʻōlelo ka Tobacco Institute of India (TII) ua hoʻololi ʻia ko lākou mau lālā a ua kūpono nā plastic biodegradable i hoʻohana ʻia i nā kūlana honua, a me ka maʻamau BIS i hoʻopuka hou ʻia. Ua ʻōlelo pū lākou e hoʻomaka ana ka biodegradation o nā plastic biodegradable i ka pilina me ka lepo a me ka biodegrades maoli i ka compost me ke koʻikoʻi ʻole o ka ʻohi ʻōpala paʻa a me nā ʻōnaehana hana hou. -
ʻO ka loiloi pōkole o ka hana ʻana o ka mākeke Calcium Carbide ma ka hapa mua o ka makahiki.
I ka hapa mua o 2022, ʻaʻole i hoʻomau ka mākeke calcium carbide kūloko i ka nui o ka fluctuation ma 2021. Ua kokoke ka mākeke holoʻokoʻa i ka laina kumu kūʻai, a ua kau ʻia i ka fluctuations a me nā hoʻololi ʻana ma muli o ka hopena o nā mea maka, ka lako a me ke koi. , a me nā kūlana lalo. I ka hapa mua o ka makahiki, ʻaʻohe hiki ke hoʻonui hou ʻia o nā mea kanu PVC carbide kūloko, a ua kaupalena ʻia ka piʻi ʻana o ka mākeke calcium carbide. He mea paʻakikī i nā ʻoihana chlor-alkali e kūʻai i ka calcium carbide e mālama i kahi ukana paʻa no ka manawa lōʻihi. -
Ua pahū ʻia ma kahi reactor PVC o kahi kanaka nunui petrochemical ma ka Hikina Waena!
Ua hoʻolaha ʻo Petkim petrochemical Turkish ma ke ahiahi o Iune 19, 2022, ua pahū ʻia ka mea kanu ʻo Aliaga. ua loaʻa ka pōʻino i loko o ka PVC reactor o ka hale hana, ʻaʻohe mea i ʻeha, ua hoʻomalu koke ʻia ke ahi, akā hiki ke hoʻopaʻa ʻia ka ʻāpana PVC no ka manawa pōkole ma muli o ka ulia. He hopena nui paha ka hanana ma ka mākeke wahi PVC o ʻEulopa. Ua hōʻike ʻia no ka mea ʻoi aku ka haʻahaʻa o ke kumukūʻai o PVC ma Kina ma mua o nā huahana kūloko o Turkey, a ʻoi aku ka kiʻekiʻe o ke kumukūʻai o PVC ma ʻEulopa ma mua o ko Tureke, ʻo ka hapa nui o nā huahana PVC a Petkim i kēia manawa ke lawe ʻia aku i ka mākeke ʻEulopa. -
