Coupling air stripping process and anaerobic digestion for the treatment of landfill leachate: organics degradation and cytotoxicity evaluation
(
Springer
, 2022 , Article)
Landfill leachate (LFL) from a controlled discharge in Tunisia was found to be highly loaded with ammonia. This study investigated the feasibility of an air stripping process aiming to mitigate the inhibitory effect of ...
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 ...
Towards fossil free cities – Emission assessment of food and resources consumption with the FEWprint carbon accounting platform
(
Elsevier
, 2022 , Article)
Current urbanization rates concentrate the ever growing demand for food, energy and water (FEW) resources particularly in cities, making them one of the main drivers of greenhouse gas emissions. The FEW nexus integrative ...
A comparison of bio-crude oil production from five marine microalgae – Using life cycle analysis
(
Elsevier
, 2022 , Article)
Marine microalgae biomass could offer a viable feedstock for sustainably producing biofuel by hydrothermal liquefaction. In this study, five promising marine microalgae (i.e., Tetraselmis, Picochlorum, Synechococcus, ...
Solar cultivation of microalgae in a desert environment for the development of techno-functional feed ingredients for aquaculture in Qatar
(
Elsevier
, 2022 , Article)
The demand for aquaculture feed will increase in the coming years in order to ensure food security for a growing global population. Microalgae represent a potential fish-feed ingredient; however, the feasibility of their ...
Exploring the Biochemical Methane Potential of Wholesale Market Waste from Jordan and Tunisia for a Future Scale‑Up of Anaerobic Digestion in Amman and Sfax
(
Springer
, 2022 , Article)
Local open markets, trading fruits and vegetables, are widespread in Mediterranean countries, such as Tunisia and Jordan, producing large amounts of organic waste. Applying an anaerobic digestion process on this substrate ...
Optimizing the Extraction Conditions of Hydroxytyrosol from Olive Leaves Using a Modified Spherical Activated Carbon: A New Experimental Design
(
Hindawi
, 2022 , Article)
The purification of hydroxytyrosol from olive leaves extract by modified activated carbon was studied experimentally in a batch system and a column by adsorption and desorption processes. The extraction yield reached 90% ...
Assessment of novel halo- and thermotolerant desert cyanobacteria for phycobiliprotein production
(
Elsevier
, 2022 , Article)
Four indigenous cyanobacteria isolates identified as QUCCCM 34: Chroococcidiopsis sp., QUCCCM 54: Pleurocapsa sp., QUCCCM 77: Euhalothece sp., and QUCCCM 129: Cyanobacterium sp. were investigated during this study. ...
Smart greenhouses as the path towards precision agriculture in the food-energy and water nexus: case study of Qatar
(
Springer
, 2022 , Article)
Greenhouse farming is essential in increasing domestic crop production in countries with limited resources and a harsh climate like Qatar. Smart greenhouse development is even more important to overcome these limitations ...
