Techno-economic analysis: Algae Cultivation

How do algae experts assist in techno-economic analysis (TEA).  TEA is the combination of conceptual process design and production cost estimation activities. Algae cultivation refers to the growth and recovery of algal biomass in open ponds or photobioreactors. Many algae strains of interest produce oils that may be used as food or nutraceuticals, or upgraded…

Optimization of Aerobic Fermentation

As most renewable energy and power companies know, power consumption during aerobic fermentation is one of the major operating costs. At any given point in the process, there are many combinations of airflow and agitation that will give the required mass transfer rate. But the combined power required of the agitator plus the compressor is…

Plastic Waste Conversion Expert

Plastic waste conversion is the transformation of plastic waste into usable sustainable products. Depending on the waste plastic composition and level of contaminations, the plastic feedstock could be effectively converted into high-value products through pyrolysis, gasification, and steam reformation. If the plastic feedstock is clean and has an appropriate composition, pyrolysis can be applied to…
