Waste-Heat Utilization

Compressed air energy storage (CAES) with compressors distributed at heat loads to enable waste heat utilization

Large scale penetration of renewable energies such as wind and solar into the electric grid is complicated by their intermittency. Energy storage systems can mitigate these fluctuations by storing off-peak energy for use at peak-demand times. Compressed air energy storage (CAES) is one of the most promising storage technologies due to the large amount of energy that can be stored at an economic...

Utilization of Alumina Waste and Silica Waste for Geopolymer Production

This research studies the utilization of alumina waste and silica waste for geopolymer production. Alumina waste was obtained from aluminium thermal metallurgy industry, silica waste was obtained from silicone recycle industry in Thailand. This present study aimed at investigating the basic physical and chemical properties of waste materials and also the optimal proportion in geopolymer product...

Waste Heat to Power Systems

Waste heat to power (WHP) is the process of capturing heat discarded by an existing industrial process and using that heat to generate power (see Figure 1). Energyintensive industrial processes—such as those occurring at refineries, steel mills, glass furnaces, and cement kilns—all release hot exhaust gases and waste streams that can be harnessed with wellestablished technologies to generate el...

Human Urine Utilization: A Waste Management Strategy

Waste management is the collection, transportation, processing, recycling or disposal of waste materials. The term usually relates to materials produced by human activity, and is generally undertaken to reduce their effect on health; the environment or aesthetics.Human urine can be well harnessed through proper waste management method. Waste management is also carried out on human urine to redu...
