Biomass utilization for bio-energy, bio-fuels or bio-based products requires reduction of the material size within specific ranges depending on feedstock specie, handling and further processing / conversion processes. Biomass size reduction is a mechanical treatment process that refers to either cutting or comminuting processes that significantly change the particles size, shape and bulk densit...
The recovery of clean energy in the form of methane-containing biogas is starting to receive tremendous attention in South Africa. However, it is unclear whether the transition from standard bio-methane production to waste-based bio-hydrogen production would improve or worsen the environmental and energetic performance as quantified by Life Cycle Assessment (LCA). The results of this study show...
The current study is aimed to utilize the microwave for isolation of colorant from neem bark and its application onto chemical & bio-mordanted cotton fabric. For the purpose, aqueous, acid and organic media have been employed to isolate the colorant and to make its application onto surface modified and bio-mordanted cotton fabric followed by microwave treatment up to 6min....
The global bio-based chemical market is growing in size and importance. Bio-based solvents such as glycerol and 2-methyltetrahydrofuran are often discussed as important introductions to the conventional repertoire of solvents. However adoption of new innovations by industry is typically slow. Therefore it might be anticipated that neoteric solvent systems (e.g., ionic liquids) will remain niche...
Bio-grout, a new ground improvement method, has been recently developed to improve the mechanical properties, decrease the permeability of porous materials, reinforce or repair cementitious materials and modify the properties of soil or sand. Bio-grout production depends on microbially induced calcite precipitation (MICP), which is driven mainly by an enzyme, urease. However, urease-based MICP ...
