Carbon sequestration is an important strategy in combating rising carbon dioxide
concentration in the atmosphere. Differing from carbon emission reduction, carbon …

The concept of biorefinery expands the possibilities to extract value from organic matter in
form of either bespoke crops or organic waste. The viability of biorefinery schemes depends …

Greenhouse gas emissions have several adverse environmental effects, like pollution and
climate change. Currently applied carbon capture and storage (CCS) methods are not cost …

CO 2 is main contributor of global warming crisis. Among various existing carbon-capture
technologies, microalgae based biological carbon-capture is one of the promising less …

Biohydrogen production and integration possibilities are vital towards hydrogen economy
and sustainability of the environment. Acidogenic fermentation is acquiring great interest …

Simultaneous digestion and in situ biogas upgrading in high-pressure bioreactors will result
in elevated CO2 partial pressure (pCO2). With the concomitant increase in dissolved CO2 …

Two-stage anaerobic digestion (AD) system is an efficient technology; however, organic
loading rate (OLR), a critical design and process parameter, influences the performance and …

CO 2 injection or biogas recirculation can affect the process of anaerobic digestion, but there
is a lack of systematic study on the injection strategy in the continuously operated reactors …

Lignocellulose usually requires pretreatment to improve biogas production. To enhance
lignocellulose biodegradability and improve anaerobic digestion (AD) efficiency, different …

This study investigates the enhancement of methane production in anaerobic co-digestion
(AcoD) through the introduction of exogenous CO₂ and the application of bamboo biochar …
