Abstract
Bio-wastes materials are the post-harvest products, created by several agricultural activities in diverse scopes in various sectors. Efficient utilization of bio-waste is purely environmental benign system and cost-effective process of waste management and holds major challenges in sustainable human society nowadays. Among the different species of banana, Bhimkol/Aathiakol scientifically named as Musa balbisiana Colla is most commonly available in North-Eastern region of India. The ash obtained from the filtrate of the extract of ash and water is called Kolakhar. The analytical result confirmed the presence of K2O with 25.09%”. Using Kolakhar, several traditional dishes are available in Assam, and it replaces the commercially available soda. This indicates that Kolakhar is a basic liquid, and has a wide scope as bio-waste catalyst for various applications especially base-catalyzed biodiesel synthesis and ligand free Suzuki–Miyaura Cross-Coupling reaction. Because of the high basicity of Kolakhar, we are expecting successive aldol condensation of 5-hydroxymethylfurfuraldehyde/furfuraldehyde with acetone that produces jet fuel intermediate chemicals. The yield of the desired product was around 95%. Among waste derived lignocellulose has been considered for the sources of platform chemicals such as 5-hydroxymethylfurfuraldehyde and furfural and fuels with value-added compounds due to easy availability and nonedible property. The cellulosic and hemicellulosic biomass could be converted into hexose and pentose sugars by acid hydrolysis process. Although, it is an important potential source for chemical intermediates, suitable traditional technology is being sought. Thus, we have reported for the conversion of waste biomass derived C6 and C5 (fructose and xylose) to platform chemicals, respectively, using super acid functionalized porous heterogeneous catalysts with yield around found to be 96%. Both the works provide a new technology for minimization of waste material to applicable material as well as its impact on reducing GHG emission and climate change.
