Life cycle energy-carbon-water footprints of sugar, ethanol and electricity from sugarcane.

Sugarcane is an important cash crop used for producing sweeteners and also some bioproducts (alcohol and bioenergy). The current study assesses life cycle energy, carbon and water footprint of sugarcane based sugar, ethanol and electricity in India. A farm to factory gate attributional life cycle assessment (LCA) is conducted to assess the energy and carbon footprints whereas the Food and Agriculture Organization's (FAO) CropWat model is used to estimate the water footprint (green, blue and grey).

A technical, economic, and environmental assessment of amine-based CO2 capture technology for power plant greenhouse gas control.

Capture and sequestration of CO2 from fossil fuel power plants is gaining widespread interest as a potential method of controlling greenhouse gas emissions. Performance and cost models of an amine (MEA)-based CO2 absorption system for postcombustion flue gas applications have been developed and integrated with an existing power plant modeling framework that includes multipollutant control technologies for other regulated emissions. The integrated model has been applied to study the feasibility and cost of carbon capture and sequestration at both new and existing coal-burning power plants.
