Abstract In 2015, the United Nations General Assembly (UNGA) set out 17 Sustainable
Development Goals (SDGs) to be achieved by 2030. These goals highlight key objectives …

Anaerobic digestion produces biogas, a mixture of CH 4 and CO 2, where CH 4 is a low
cost, environmentally friendly, and renewable energy source. The application of biogas …

The inherent capability and increased efficiency of microalgae to convert sunlight into solar
chemical energy are further enhanced by the higher amount of oils stored in microalgae …

The boost of the greenhouse gases (GHGs, largely carbon dioxide–CO 2) emissions owing
to anthropogenic activity is one of the biggest global threats. Bio-CO 2 emission reduction …

As a common biological engineering technology, anaerobic digestion can stabilize sewage
sludge and convert the carbon compounds into renewable energy (ie, methane). However …

Commercialization of microalgal biofuels is not yet attained even after plentiful of research
and extensive scientific projects. Expending the cost and energy for producing single …

Biogas production is rising in the context of fossil fuel decline and the future circular
economy, yet raw biogas requires purification steps before use. Here, we review biogas …

Microalgae (MA) biorefinery is a vital platform for the conversion of biomass into biofuels,
biomaterials, and bioactive substances and it can remediate the pollutant from the …

Biogas is a resource of renewable energy with the highest significance to development in
many countries due to the great accessibility to biomass. It is mostly produced by the …

Microalgae have received much interest as a biofuel feedstock. However, the economic
feasibility of biofuel production from microalgae does not satisfy capital investors. Apart from …
