Ngaphandle kwamafutha e-hemp asetshenziswa kwizicelo eziningi zezimboni ezifana ne-ejenti yokucima ukopende, njengesithambisi nesithambisi, isitshalo se-hemp (i-Cannabis sativa) singasetshenziswa njengephepha, ukukhipha ubuthi emhlabathini futhi njengomthombo kaphethiloli.
I-Hemp Njengephepha
Ukusetshenziswa kwe-Hemp ephepheni kungalandelelwa emuva ku-200 - 150 B.C. ngenkathi eChina kwenziwa ukuthi ibumba i-hemp edonswe yaba amashidi amancanyana. Ngekhulu lesi-7, kwakhiwa izindiza zamaphepha eMiddle East naseChina. Ukusetshenziswa kwephepha le-hemp kusakazeka ngasentshonalanga. AmaBhayibheli nezinoveli zababhali abanjengoMark Twain zazinyatheliswa ephepheni le-hemp kanti eRussia i-hemp yayisetshenziselwa ukuphrinta imali nezitembu.
Iphepha lingenziwa kusuka ku-bast fibre ende noma nge-pulp fibre emfushane. Iphepha elenziwe ngemicu emide lincane futhi liqinile. Iphepha elenziwe nge-pulp-fibre emfushane kungenzeka lingabi namandla, kepha kube lula ukwenza, lithambile futhi libe likhulu futhi lilungele ukusetshenziswa kwansuku zonke. Ngaphezu kwalokho, i-hemp ihlala i-eco-friendly njengoba i-hemp ithatha kuphela izinsuku ezingama-120 ukukhula ekuvuthweni kuqhathaniswa neminyaka ethatha isihlahla ukuze ikhule.
I-Hemp Njengesivimbi Soshefu
Izitshalo ze-Hemp zingasetshenziswa kwinqubo yokubuyisela inhlabathi ekungcoleni okunobuthi, ukudonsa ubuthi benhlabathi njengesiponji. I-Hemp yaze yasetshenziswa ukukhipha ama-radioactive enhlabathini kulandela inhlekelele yomsakazo eChernobyl eRussia ngo-1986.
Ukucwaninga okwengeziwe ngo-2012 kukhombisa ukuthi i-cadmium idonswa ngempumelelo enhlabathini. I-Cadmium ingukukhiqizwa kokukhipha kokubasa kwezinto ezi-futhos. I-Hemp ingahlanza ubuthi emhlabathini kubandakanya izinsimbi, ukubulala izinambuzane, uwoyela ongahluziwe kanye nobuthi ku-landfill. I-Hemp ekhule enhlabathini enobuthi akufanele isetshenziselwe ukusetshenziswa komuntu.
I-Hemp Njengo-Biofuel
Abaphenyi e-University of Connecticut bathola ukuthi amafutha enziwe ngodizili angenziwa ngembewu ye-hemp yezimboni. Ucwaningo lwenyuvesi lukhombisa ukuthi uwoyela we-hemp wayenesilinganiso sokuguqulwa kwama-97% saba ama-biodiesel nokuthi i-biodiesel ilungele noma iyiphi injini ejwayelekile yedizili.
Isitshalo sonke singasetshenziswa ukukhiqiza i-ethanol noma i-methanol. Kwesinye isikhathi okubizwa nge-“hempanol” noma “hempoline” lolu hlobo lwamafutha lwenziwa ngenqubo ebizwa ngokuthi yi-cellulolysis ekhipha futhi isuse i-hemp ukukhipha i-ethanol. I-Ethanol iyakhula ngemuva kokuvutshelwa kwezinto zokutshala kanye ne-methanol kukhiqizwa ngemuva kokuqunjelwa owomile kwepulangwe eliqhutshwa ngamapulangwe.
