ICyclalg, iphrojekthi yaseYurophu yokwenziwa kwemishini ye-biorefinery ene-algae

I-cyclalg iphrojekthi yaseYurophu inhloso yayo kungukwakha i-biorefinery lapho zonke izinqubo ezidingekayo zokukhiqiza i-biodiesel zithuthukiswa futhi ziqinisekiswe ngokusebenzisa isiko le-microalgae. Izikhungo zobuchwepheshe eziyisithupha ezitholakala IFrance, iNavarra ne-Euskadi, futhi kulindeleke ukuthi ithathe iminyaka emithathu, ngesabelomali se 1,4 million euro.

Inhloso enkulu yephrojekthi ukusungula imodeli entsha ye umnotho oyindilinga ngokukhiqizwa kwe-biodiesel namanye ama-biofuel avela ku-microalgae. Le modeli ifuna ukusizakala ngodoti wemvelo okhiqizwayo ukuze uyisebenzise njengokudla kwe-microalgae, ngaleyo ndlela ithuthukise ukukhula kwayo futhi ihlanganise uhlelo oluzimele noluzinzile. Imfucuza ayisebenzi kabusha kuphela ngaphakathi kwenqubo kodwa, ngokwelula impilo yayo ewusizo, imikhiqizo ewusizo ingatholwa imboni yamakhemikhali, amandla kanye nezolimo.

Ukubaluleka kwe-microalgae ekukhiqizeni i-biodiesel

Ama-Microalgae ama-oleaginous microorganisms anekhono elimangalisayo lokukhula ngokushesha endaweni ehlala emanzini. Zithandeka kakhulu ekukhiqizeni i-biofuel ngenxa yazo high lipid density, kubalulekile ohlelweni lokuguqula amafutha abe yi-biodiesel ngokusebenzisa i- i-esterification.

Ngokungafani nezitshalo zendabuko ezifana nommbila noma umoba, i-microalgae ayiqhudelani nomhlabathi ovundile odingekayo ekukhiqizeni kwezolimo. Ukwengeza, banamandla okwenza bamba i-CO2 kusuka emkhathini ngendlela ephumelela kakhulu kunezitshalo zasemhlabeni, okusiza ekwehliseni ukukhishwa kwamagesi abamba ukushisa njengoba zikhula. Elinye iphuzu elibalulekile ukuthi zingakhula ezinhlotsheni ezahlukene zamanzi: fresh, anosawoti ngisho emanzini angcolile, ephindaphinda amathuba okusetshenziswa kwawo ezindaweni ezahlukene kanye nezimo zemvelo.

I-Neiker-Tecnalia: Umxhumanisi wephrojekthi

INeiker-Tecnalia, isikhungo sobuchwepheshe e-Basque Country, sixhumanisa iphrojekthi ye-Cyclalg, enesibopho sokuqinisekisa ukusebenza kahle kwezomnotho kanye nemvelo kokutshalwa kwe-microalgae ukukhiqizwa kwe-biodiesel. Lokhu kusho ukwenza ngcono i- izimo ezikhulayo ukuqinisekisa ukuthi imbuyiselo yanele ukuthethelela umzamo wokuqala kanye nokutshalwa kwezimali.

Enye yezinselelo ezibaluleke kakhulu zeCyclalg ukuthola ingxenye efanele yemfucuza yemvelo esebenza njengokudla kolwelwe oluncane. Ngesikhathi sephrojekthi edlule, I-Energreen (okwenzeka phakathi kuka-2012 no-2014), ukusetshenziswa kwe-algae ekukhiqizeni i-biodiesel kwaqinisekiswa, kodwa izinkinga zatholakala lapho kusetshenziswa amafutha e-organic residual, ngenxa yokwakheka kwawo. Lezi mfucumfucu, nakuba zicebile ngamaprotheni noshukela, azihlali ziziphatha ngokuzinzile phakathi nomjikelezo wokukhiqiza, odinga izifundo ukulungisa izinqubo.

Umqondo we-biorefinery

Una umshini we-biorefinery ilandela umqondo ofanayo njengendawo yokuhluza yendabuko, kuphela esikhundleni sokusebenzisa uwoyela ongahluziwe, iyacubungula i-biomass organic, kulokhu microalgae. Ngaphakathi kwe-biorefinery, zonke izingxenye ze-biomass ziyakhishwa futhi zisetshenziswe, kutholwe ama-bioproducts ahlukahlukene ngomjikelezo oqhubekayo. Njengoba kuyi-microalgae biorefinery, inhloso enkulu ukukhiqiza i-biodiesel, kodwa amanye ama-biofuels nawo angatholakala njenge bioethanol o biogas, kanye nemikhiqizo yesibili engezwe inani njenge ama-biofertilizer y ukudla kwezilwane.

Le ndlela ebanzi iwukhiye wokuqinisekisa ukusebenza kahle kwezomnotho, njengoba ivumela imikhiqizo eminingi ukuthi itholakale emthonjeni owodwa we-biomass. Endabeni ye-Cyclalg, kubhekwa ukuthi kungenzeka yini ukukhipha izinhlanganisela ezihlukahlukene, kusukela ku-biofuels kuya kwezithako ezingasetshenziswa embonini yamakhemikhali, yezimonyo neyokwenza imithi, njengama-antioxidants, i-lipids namaprotheni.

Impumelelo yephrojekthi izoncika ezintweni ezimbalwa

• Ukwenza ngcono ukutshalwa kwe-microalgae: Ukuthuthukiswa kwama-photobioreactors asebenzayo futhi asimeme.
• Ukusetshenziswa kukadoti: Sebenzisa ngokunenzuzo udoti wemvelo njengengxenye yokukhula kolwelwe oluncane.
• Khiqiza ama-bioproducts anenzuzo: Nweba umjikelezo.
