Okunye okusha esikhundleni sikawoyela kusisondeza emandleni ahlanzekile

Siyisinyathelo esisodwa esilinde ilungelo lobunikazi esiseduze nekusasa esingancikile kangako emandleni kaphethiloli. Iqembu labacwaningi bamazwe ngamazwe bathole indlela yokudiliza lignin, i-polymer eyinkimbinkimbi engasetshenziswa njengenye indlela yamakhemikhali e-petrochemicals. 

“Sikwazile ukukhiqiza izandulela ezisimeme kakhulu zezinto ezifana namapulasitiki, izinto zokubasa nezinto ezifana nezihlanzi ezivela ezitshalweni, esikhundleni sokuphuma kuphethiloli ongasimame kangako,” kusho umholi wethimba labacwaningi, uJeremy S. Luterbacher, uMsizi uSolwazi Ecole Polytechnique Fédérale de Lausanne ( EPFL), ku-a Izindaba Isikhungo Sesayensi Yamakhemikhali Nobunjiniyela ividiyo.

Eqaphela "ikhemikhali yayo njengento eqondile," uLuterbacker uthe, "Imakethe inzima kumandla esimeme ikakhulukazi ngenxa yokusekelwa okungaguquki kwezombusazwe kanye nezintengo zamandla ezihluka kakhulu. Abatshalizimali balezi zinkundla ezintsha kunzima ukubathola emakethe engaqinisekile, ikakhulukazi uma kucatshangelwa ukuncintisana kwamafutha asezinze kahle.” 

I-Lignin ilandisa ngenqwaba yalokho okunikeza ukhuni namagxolo ukuqina, kodwa ukwakheka kwawo kwamangqamuzana kuwumklomelo wangempela, nokuminyana kwamandla okungu-30% okukhulu kunoshukela wendabuko osetshenziselwa ukukhiqizwa kwe-biofuel ngokusho kwe-athikili ye-PHYS.ORG. I-Biofuels Digest futhi ikhomba ohlwini oluvelayo lwabahlinzeki kanye nabakhiqizi abazimisele ukuthengisa ushukela we-cellulosic kanye/noma i-lignin ukuze kwenziwe ucwaningo futhi bawusebenzise ezinhlobonhlobo zezicelo zentengiso. 

Ukwengeza i-formaldehyde, ikhemikhali esetshenziswa kakhulu futhi ekhiqizwe ngokushibhile, ukudiliza ushukela wezitshalo ezingadliwa, abacwaningi be-EPFL baphendule lokho uLuterbacker akubiza ngokuthi "i-black crud" ibe "into emangalisayo" mayelana nendawo engaba khona ye-fossil fuel. U-Luterbacker uphinde wachaza ukufana okumangalisayo kwamakhemikhali e-lignin ne-petroleum.
