A systems thinking approach to understanding the challenges of achieving the circular economy
( Springer Nature , 2020 , Article)Circular economy (CE) is extensively discussed around the globe. Presently, discussions are mostly concerned with the importance of achieving CE and the benefits associated therewith, with the various barriers surrounding ... -
Techno-economic modelling of high-value metabolites and secondary products from microalgae cultivated in closed photobioreactors with supplementary lighting
( Elsevier , 2022 , Article)The purpose of this study is to develop an initial computational model to evaluate the techno-economic viability of high-value and secondary resources from microalgae. The isolation of high-value metabolites is the driving ... -
Techno-economics of algae production in the Arabian Peninsula
( Elsevier , 2021 , Article)The Arabian Peninsula's advantageous climate, availability of non-arable land, access to seawater and CO2-rich flue gas, make it an attractive location for microalgae biomass production. Despite these promising aspects, ... -
The effect of culture salinity on the harvesting of microalgae biomass using pilot-scale tangential-flow-filter membrane
( Elsevier Ltd , 2019 , Article)In this study, the effect of culture salinity (4–6% NaCl) on the harvesting of two microalgal strains (i.e., Picochlorum sp., and Tetraselmis sp.) was investigated using pilot-scale TFF membranes. The cultures of these two ... -
