TL;DR: In this paper, the potential of using pristine and engineered biochar as CO2 capturing media, as well as the factors influencing the CO2 adsorption capacity of biochar and issues related to the synthesis biochar-based CO2 adorbents, are summarized and evaluated.

TL;DR: The biochars derived from biowaste (food waste and wood waste) could be effective adsorbents for CO2 capture by providing green solution for food waste recycling and showing >99% recyclability during 10 consecutive adsorption-desorption cycles.

TL;DR: A comprehensive overview of the limitations with the existing upgrading technologies along with recent advances in physical, chemical, and biological biogas upgrading technologies (e.g., pressure swing adsorption, membrane separation, biochar adaption and CO2 conversion by biological organisms) and further into possible future solutions, such as hybrid systems are discussed as discussed by the authors.

TL;DR: In this article, a review of major technologies for nitrogen and phosphorus control from agricultural runoff are summarized along with discussion of newly proposed technologies such as biochar biomimetics and microbial catalyst.

TL;DR: In this paper, a combination of KOH and CO2 activation for enhancing the CO2 adsorption capacity of gasification biochar was evaluated in terms of physicochemical properties, including surface area, micropore volume, and regeneration ability.
