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...

The most commonly used technology for dealing with medical waste, till recently was an incinerator. Incinerator, when introduced was supposed to be a wonder technology. A technology that would get rid of loads of waste by burning it and would leave behind some ash, that could be dumped. However, instead of solving the problem of waste, it aggravated it. It only changed the biological problem in...

The current estimates and glass formulation efforts have been conservative in terms of achievable waste loadings. These formulations have been specified to ensure that the glasses are homogenous, contain essentially no crystalline phases, are processable in joule-heated, ceramic-lined melters and meet Hanford Tank Waste Treatment and Immobilization Plant (WTP) Contract terms. The WTP’s overall ...

This paper includes the significant on-site experience of the authors related to problems faced in amine systems with fresh amine and their possible solutions in phases#2&3 of South Pars gas                complex. The amine system was designed as a closed circuit system with the primary objective of removing H2S, CO2, and other acidic components from gaseous hydrocarbon streams. Amine plant op...

Home composting systems (HC) are known to facilitate municipal solid waste management, but little is known about their environmental impact including their greenhouse gas emissions (GGE). The present research focused on selecting HC configuration producing the least CH(4) and N(2)O. Thus, 4 HC types were used to compost food and yard waste for 150 days and monitored for CO(2), CH(4) and N(2)O a...
