Wastewater Treatment for Carbon Dioxide Removal [PDF]

ACS Omega, 2023
Wastewater treatment is notorious for its hefty carbon footprint, accounting for 1-2% of global greenhouse gas (GHG) emissions. Nonetheless, the treatment process itself could also present an innovative carbon dioxide removal (CDR) approach. Here, the calcium (Ca)-rich effluent of a phosphorus (P) recovery system from municipal wastewater (P recovered ...

Editorial: Governing Carbon Dioxide Removal [PDF]

Frontiers in Climate, 2021
Carbon dioxide removal (CDR), also known as negative emissions, greenhouse gas removal, or simply carbon removal, is in need of effective governance. If governments are to deliver on the growing number of pledges to meet “net zero” and “net-negative” emissions targets, and if the world is to successfully limit global warming to “well-below 2°C ...

Expected Limits on the Potential for Carbon Dioxide Removal From Artificial Upwelling

Frontiers in Marine Science, 2022
Artificial upwelling, the engineered upward pumping of deep ocean water, has long been proposed as a technique to fertilize the ocean and, more recently, remove atmospheric carbon dioxide.

Ocean Carbon Dioxide Removal and Storage. [PDF]

Chem Rev
The ocean, Earth's largest carbon reservoir, exerts a central role over atmospheric CO2 through its capacity to store carbon primarily as bicarbonate ions. Direct observations indicate that the global ocean has a net carbon uptake of 2.6-3.0 petagrams of carbon annually, representing nearly 30% of anthropogenic CO2 emissions.

Scientific literature on carbon dioxide removal revealed as much larger through AI-enhanced systematic mapping [PDF]

Nature Communications
Carbon dioxide removal plays an important role in any strategy to limit global warming to well below 2 °C. Keeping abreast with the scientific evidence using rigorous evidence synthesis methods is an important prerequisite for sustainably scaling these ...

Extracorporeal carbon dioxide removal for the treatment of acute hypoxaemic respiratory failure: the REST RCT

Health Technology Assessment
Background In patients who require mechanical ventilation for acute hypoxaemic respiratory failure, further reduction in tidal volumes, compared with conventional low tidal volume ventilation, may improve outcomes.

Review of Economics and Policies of Carbon Dioxide Removal. [PDF]

Curr Sustain Renew Energy Rep
Abstract Purpose of review Despite the increasing political attention and support, the high costs of many carbon dioxide removal (CDR) technologies remain a barrier to their large-scale deployment. We provide an overview of the economics for two key CDR options – BECCS and DACCS – and review proposed and existing CDR ...

Canada's marine carbon sink: an early career perspective on the state of research and existing knowledge gaps

FACETS, 2023
Improving our understanding of how the ocean absorbs carbon dioxide is critical to climate change mitigation efforts. We, a group of early career ocean professionals working in Canada, summarize current research and identify steps forward to improve our ...

The Effects of Carbon Dioxide Removal on the Carbon Cycle [PDF]

Current Climate Change Reports, 2018
Increasing atmospheric CO2 is having detrimental effects on the Earth system. Societies have recognized that anthropogenic CO2 release must be rapidly reduced to avoid potentially catastrophic impacts. Achieving this via emissions reductions alone will be very difficult.

Regional anticoagulation with heparin of an extracorporeal CO2 removal circuit: a case report

Journal of Medical Case Reports, 2019
Background Extracorporeal carbon dioxide removal is an increasingly used respiratory support technique. As is true of all extracorporeal techniques, extracorporeal carbon dioxide removal needs proper anticoagulation. We report a case of a patient at risk
