“Sustainable
Production is the creation of goods and services using processes and
systems that are: non-polluting; conserving of energy and natural
resources; economically efficient; safe and healthful for workers,
communities, and consumers.” said by Engr. Asif Muhammad Sami while
speaking as keynote speaker in the seminar at Green University of
Bangladesh (GUB). The department of textile engineering of GUB organized
the seminar titled ‘Sustainable Textile Wet Processing’ at their campus in Mirpur, Dhaka on 9th
October 2013. The program was chaired by Prof. Dr. Md. Saifur Rahman,
Dean, faculty of Science & Engineering and Chairperson of the
department of Textile Engineering and hon’ble Vice Chancellor Professor
Dr. Md. Golam Samdani Fakir was present as the chief guest at the event.
Prof.
Samdani appreciated the initiative taken by the Green University
Textile Club and thanked the keynote speaker for discussing advanced
ideas about sustainable textile wet processing. The chief guest added
that students would absorb the knowledge and engage them in utilizing
and developing new technologies in their practical field to ensure
greener production.
Chairperson
of the seminar Prof. Saifur Rahman acknowledged that it is essential
rather than just desirable for every textile engineers to be aware of
the social, economic and ecological benefits of environmentally friendly
textile processing routes and to apply them in their respective fields.
He strongly suggested that production of high and consistent product
quality in a cost effective manner considering overall environmental
friendliness is a must to ensure sustainable green trends in textile
processing.
Keynote
speaker Mr. Sami recognized ‘Minimizing air, water pollution’,
‘Optimizing resources: water, energy, dyes & chemicals, time’,
‘Ensuring Workers safety’ and ‘Ensuring Customers safety &
satisfaction’ are the main concerns of sustainable wet processing. He
clearly explained the contributors to carbon footprint & green
solution. He also focused on important environmental concerns related to
textile wet processing like Intensive chemical based wet processing
like scouring, bleaching, mercerizing, dyeing, printing etc; dyestuffs
auxiliaries consisting heavy metals; PVC and phathalets used in
plastisol printing paste; formaldehyde found in dispersing agents etc.
Implementing and practicing sustainable textile wet processing concept
can minimize the hazardous effect, he added.
He
demonstrated various recently developed techniques like ultrasonic
assisted wet processing, digital printing technology, nanotechnology,
biotechnology, plasma technology as the green solution of vital
environmental issues.
Mr.
Sami emphasized on eco-friendly reactive dyeing with high fixation
rate. He also showed the advantages of supercritical fluid dyeing over
the conventional water based dyeing. He said that eco-friendly effluent
treatment method should be practiced in each factory. Combined
biological system with electron-beam or advanced oxidation process (AOP)
method or Reverse Osmosis (RO) is the existing eco- friendly effluent
treatment method, he added.
Keynote speaker Engr.
Asif Muhammad Sami is the CEO of Euro Asiatic Resources, Chairman - SS
Vision Ltd & Chairman- Fujiama Trade International Limited. Mr. Sami is also the Textile Consultant of Perseus Ltd. He is an expert in Textile Wet Processing & cleaner production.
