This review focuses on our research findings about efficiency of different nano materials synthesized by us for photocatalytic hydrogen production from industrial wastes. Lab-scale reactors were fabricated liquid phase alkaline waste streams and gaseous sulfide. The effects operating parameters namely pH, flow rate, light intensity, depth, sulfide sulphite concentration investigated 7 photocata...

I n common with most industrial processing industries, the fermentation industries are concerned with waste disposal situations that often become critical. Fermentation wastes usually occur in liquid or solid forms, although some gaseous wastes are also produced. It is worthy of note that, in addition to the problems involved, the disposal of these wastes is particularly interesting to fermenta...

Our societies generate increasing volumes of organic wastes. Considering that we also need alternatives to oil, an opportunity exists to extract liquid fuels or even industrial solvents from these abundant wastes. Anaerobic undefined mixed cultures can handle the complexity and variability of organic wastes, which produces carboxylates that can be efficiently converted to useful bioproducts. Ho...

Industrial Ecology involves the transformation of industrial processes from linear to closed loop systems: matter and energy flows which were initially considered as wastes become now resources for existing or new processes. In this paper, Thermoeconomics, commonly used for the optimization and diagnosis of energy systems, is proposed as a tool for the characterization of Industrial Ecology. Th...
