Shell-based agricultural wastes biomass valorization for biofuel production: a bibliometric analysis into the circular bioeconomy.

The valorization of shell-based agricultural waste biomass for biofuel production represents a promising approach within the circular bioeconomy. This study employs a bibliometric analysis to investigate research trends and identify key developments in the field from 1997 to 2023, using data from the Web of Science and VOSviewer for scientific mapping. A total of 1333 research articles were examined, revealing notable shifts in research focus: from pyrolysis and biomass energy (1997-2005) to gasification (2006-2014), and more recently, to enzymatic hydrolysis and lignocellulosic biomass gasification (2015-2023).

A novel oyster shell biocomposite for the efficient adsorptive removal of cadmium and lead from aqueous solution: Synthesis, process optimization, modelling and mechanism studies.

This study highlights the effectiveness of oyster shell biocomposite for the biosorption of Cd(II) and Pb(II) ions from an aqueous solution. The aim of this work was to modify a novel biocomposite derived from oyster shell for the adsorption of Cd(II) and Pb(II) ions from aqueous solution. The studied revealed the specific surface BET surface area was 9.
