This technology could be alternative for conventional technologies, offering the promise of competitive performance combined with an environment friendly system with a few or no moving parts, and no need for lubrication or sliding seals.
Environment friendly binders with relatively low energy consumption and low emissions may be an alternative to energy-intensive cement.
Green solvents and technology are aimed to develop an environment friendly process with simultaneous reduction of pollutants [6, 7] for oil extraction.
The current study aimed at investigating the utilization of ionic liquids (ILs), known as environment friendly salt with good solubility, thermal stability and effective surface activity, as an alternative to conventional organic surfactants in enhanced oil recovery process.
The non-toxicity of the adsorbent, its reusability and simple method of preparation are its added advantages making it an environment friendly material with potential to be used in water treatment.
Theoretically, cyclopentanol could be synthesized using a two-step process from cyclopentene, e.g., the addition-esterification reaction of cyclopentene with acetic acid, the transesterification of cyclopentyl acetate and methanol, the process of hydration of cyclopentene was one environment friendly technology with less pollution [6].
Fluidized bed combustors (FBC) are becoming the core of 'clean wastes technology' for power production, owing to their efficient and clean burning of coal and other solid fuels including biomass and other wastes, in an environment friendly manner with reduced pollutants.
