Eco-friendly method turns raw biomass into high value chemicals

IANS  |  Kolkata 

An international team of researchers, including from and Bangladesh, has developed a cost-effective method of converting non-edible agricultural biomass, such as jute, or the from crops, into commercially valuable for and companies.

Researchers from the (UOW), working with colleagues in India, and who participated in the study, say that most large-scale crops produce a huge quantity of non-edible and turning that into an economically valuable product will add significant value to those crops.

"We collected raw such as bagasse, rice husk, wheat straw, cotton stalk, and low grade from different areas of and and converted it into such as xylose and arabinose, furfural and HMF (5-hydroxymethylfurfural), which are used in the industry and in pharmaceuticals," from for Innovative Materials(AIIM) in a statement on Sunday. Furfural is a

from National University who was one of the main collaborators in this project said five-carbon sugars and furfural were highly with widespread uses.

"Xylose and Arabinose are healthy, five-carbon, low glycemic index sugars. Used in food products, these five-carbon sugars can play an important role in the management of blood glucose and insulin levels related to sucrose intake," said.

In addition, furfural is one of the leading value-added produced from because of the variety of uses it can be put to. Furfural and its derivatives have been widely applied as fungicides, pesticides, drugs and bioplastics, flavour enhancers.

Also, there has also been renewed interest in furfural for its potential use in the production of biofuels, such as bioethanol and biodiesel.

The method the researchers developed has advantages over existing conversion methods as it produces a very high yield of five-carbon sugar and furfural, and the catalyst materials used are recyclable, making it significantly cheaper and more environmentally friendly and efficient.

All the raw biomasses (sugar mill waste bagasse, rice husk, wheat straw, cotton stalk, and low grade jute) used in this research are abundant, very cheap, and renewable resources in and other South Asian countries, the researchers said in the study published in Scientific Reports."This discovery will add significant economic value to the agricultural waste materials through industrialisation of our technique in Bangladesh and other South Asian countries.

"We foresee a significant economic improvement of these developing countries would happen if green bio-industries are developed for utilising these crop waste and turning it into a valuable product by using our discovery," said Tofazzal Islam, one of the co-authors and collaborators of this research from the Department of of in Bangladesh.
