WCAS holds lec­ture on ‘Bi­o­log­i­cal Waste Man­age­ment of Paper’

Muscat Daily - - PRESS RELEASES -

Prof (Dr) S L Gupta, dean, WCAS, said, “To in­cul­cate the cul­ture of re­search in col­lege, WCAS has started spon­sor­ing re­search projects from the year 2016.”

Dr Sadaf Zehra, HoD, Depart­ment of Biotech­nol­ogy, who re­cently com­pleted the col­lege's spon­sored re­search project de­liv­ered a lec­ture on 'Bi­o­log­i­cal Waste Man­age­ment of Paper' in the col­lege premises.

The prin­ci­pal in­ves­ti­ga­tor of the project was Dr Sadaf who said that Oman can ben­e­fit from bi­o­log­i­cal waste man­age­ment of paper. She said paper re­cy­cling is the process of turn­ing waste paper into new paper prod­ucts. In con­ven­tional meth­ods, paper re­cy­cling in­volves mix­ing used paper with wa­ter and chem­i­cals to break it down. It is then chopped up and heated, which breaks it down fur­ther into strands of cel­lu­lose, a type of or­ganic plant ma­te­rial; this re­sult­ing mix­ture is called pulp or slurry. It is strained through screens, which re­moves any glue or plas­tic that may still be in the mix­ture and it is then cleaned, de-inked, bleached and mixed with wa­ter. Then, it can be made into new paper.

Dr Sadaf said that the paper in­dus­try has been in­ves­ti­gat­ing bi­o­log­i­cal re­place­ments for some of the chem­i­cals used in the pa- per­mak­ing process in hopes of re­duc­ing cap­i­tal and op­er­at­ing costs and min­imis­ing its en­vi­ron­men­tal im­pact. One area where bi­o­log­i­cal re­place­ments have a good op­por­tu­nity in the paper in­dus­try is in re­cy­cled fi­bre ap­pli­ca­tions.

Dr Sadaf's re­search fo­cused on the non-harm­ful bi­o­log­i­cal pro­cesses used to re­cy­cle or mod­ify the waste prod­ucts into use­ful prod­ucts. Dr Sadaf said, “At this time of cri­sis when the world is look­ing for al­ter­na­tive en­ergy sources and con­serv­ing our en­vi­ron­ment at the same time, the pro­posed re­search find­ings can prove to be very help­ful for the econ­omy of Oman.”
