Carbon dioxide sequestration in cement kiln dust through mineral carbonation.
TL;DR: The degree of mineral carbonation achievable in cement kiln dust (CKD) underambienttemperatures and pressures was examined through a series of batch and column experiments, and sequestration appears to follow unreacted core model theory where reaction kinetics are controlled by a first-order rate constant at early times.
Journal ArticleDOI
Mineral carbonation for carbon sequestration in cement kiln dust from waste piles
TL;DR: The first study examining the feasibility of carbon sequestration in cement kiln dust (CKD), a byproduct generated during the manufacturing of cement, finds that the overall extent of carbonation/sequestration was greater in columns with lower water contents, and the major sequestration product appears to be calcite.
Journal ArticleDOI
Vapor transport in unsaturated soil columns : implications for vapor extraction
TL;DR: In this article, a mathematical model was derived to examine the impact of gas advection, gas diffusion, gas water mass transfer, gas-water partitioning, sorption, and intraaggregate diffusion on subsurface movement of organic vapors.
Journal Article
Enabling Sustainable Thinking in Undergraduate Engineering Education
TL;DR: In this paper, the authors address the need for curricular changes that foster sustainable thinking and review a number of engineering curriculum changes at selected universities, drawing comparisons to medical and other fields, and examine the level at which sustainability concepts and active learning methods were integrated into its curricula.
Journal ArticleDOI
Life cycle assessment of vertical and horizontal flow constructed wetlands for wastewater treatment considering nitrogen and carbon greenhouse gas emissions.
TL;DR: The LCAs were used to assess the importance of nitrogen removal and recycling, and the potential for optimizing nitrogen removal in constructed wetlands, and suggest that constructed wetlands have less environmental impact.
