[1] According to the science-based research database, Scopus, he is considered to be the leading scientist in the study of jute worldwide.
[10] In 1984, Khan started his professional career as a Scientific Officer in Radiation and Polymer Chemistry Laboratory, Bangladesh Atomic Energy Commission.
From 2009 to 2015, he was the Chief Scientific Officer and Director of Institute of Radiation and Polymer Technology, Bangladesh Atomic Energy Commission.
In 2003, 2005, 2007, 2010 and 2014, he was Alexander von Humboldt fellow (AvH) in Fraunhofer Institute for Applied Polymer Research and University of Kassel, Germany.
He invented biodegradable polybag (Sonali Bag) from jute fiber to remove plastic pollution.
[24] He has invented natural plant growth promoter from prawn shell,[25] liquate biofertilizer from textile effluent,[26] etc.
The cellulose used in Sonali Bags is extracted from jute, a major vegetable fiber crop grown across the globe.
The main aim of biodegradable, compostable, recyclable and environmental friendly packaging material is to imitate the life cycle of biomass, which includes conservation of fossil resources, water, and CO2 production.
The roots of plants can easily penetrate into the bag during landfill, and there is no harmful effect on seed germination.
The biodegradable packaging materials of Sonali Bag start to dissolve in water after 5 hours and are formed into biological foods.
People may raise this polymer by planting trees on earth, so the environmental problems will be no longer as severe as today.
Now Jutin is being manufactured in Khan's laboratory manually but a pilot-scale production facility is under construction collaborating with a private entrepreneur.
