Mazo, Aaron (2016): The Technological Abyss: Heideggerian Ontology and Climate Change

Mazo, Aaron (2016): The Technological Abyss: Heideggerian Ontology and Climate Change. In Earth Common Journal 6 (1). Available online at http://www.inquiriesjournal.com/articles/1559/the-technological-abyss-heideggerian-ontology-and-climate-change.

"Whenever a decision is made in a social, political, or economic context, it is implicitly grounded in an ethical outlook. But where do these outlooks come from? To investigate this query, I examine the basis for ethical decisions regarding technology, focusing specifically on geoengineering responses to climate change."

Power, Ian M.; et al. (2021): Carbonation, Cementation, and Stabilization of Ultramafic Mine Tailings

Power, Ian M.; Paulo, Carlos; Long, Hannah; Lockhart, Justin A.; Stubbs, Amanda R.; French, David; Caldwell, Robert (2021): Carbonation, Cementation, and Stabilization of Ultramafic Mine Tailings. In Environmental science & technology 55 (14), pp. 10056–10066. DOI: 10.1021/acs.est.1c01570.

"A promising approach for de-risking brucite-bearing ultramafic tailings is in situ cementation via carbon dioxide (CO2) mineralization, which also sequesters this greenhouse gas within carbonate minerals. In cylindrical test experiments, brucite [Mg(OH)2] carbonation was accelerated by coupling organic and inorganic carbon cycling. Waste organics generated CO2 concentrations similar to that of flue gas (up to 19%)."
