This book covers various technological aspects of sustainableenergy ecosystems and processes that improve energy efficiency, andreduce and sequestrate carbon dioxide (CO2) and othergreenhouse emissions. Papers emphasize the need for sustainabletechnologies in extractive metallurgy, materials processing andmanufacturing industries with reduced energy consumption andCO2 emission. Industrial energy efficient technologiesinclude innovative ore beneficiation, smelting technologies,recycling, and waste heat recovery. The book also containscontributions from all areas of non-nuclear and non-traditionalenergy sources, including renewable energy sources such as solar,wind, and biomass.Papers from the following symposia are presented in thebook:Energy Technologiesand Carbon Dioxide ManagementRecycling andSustainability UpdateMagnetic Materialsfor Energy Applications VSustainable Energyand Layered Double HydroxidesHigh-temperatureSystems for Energy Conversion and StorageStructural Materials,Heat Transport Fluids, and Novel System Designs for High Power andProcess Heat Generation
