Measuring supply chain carbon efficiency : a carbon label framework
In the near term, efficiency improvements represent a key option for reducing the impacts of climate change. The growing awareness of climate change has increased the attention regarding the carbon emissions "embedded" in the products we consume. This increased attention creates a need to measure …

The treatability of a munitions-manufacturing waste with activated carbon
Activated carbon is rapidly becoming important as a treatment agent for both industrial and domestic wastes. The treatability of a munitions-manufacturing waste with activated carbon was investigated. The treatability of the waste was assessed in the laboratory by several methods used routinely for …

Design optimization of two-way spanning concrete systems for low-carbon, context-informed construction
… CO₂ emissions. Within these emissions, embodied carbon of construction materials is substantial. Two broad strategies to reduce embodied carbon are materials substitution and geometric optimization. This dissertation focuses on the latter, presenting strategies to reduce embodied carbon in floors …

Co-gasification of coal and biomass
… or air. The gasification reaction produces CO2 (Carbon-dioxide), H2 (Hydrogen), CO (Carbon-monoxide), CH4 (Methane) and other lower hydrocarbons. The gas produced from a gasifier, known as syngas, can used to produce electricity and liquid fuels. Coal and biomass are used in a gasfier as …
