Environmentally Friendly Technologies

Photocatalysis is a fundamental feature of life processes on our planet [1] (it provides photosynthesis in plants and bacteria) and of the chemistry of its atmosphere [2]. Work is under way to develop photocatalytic technologies for abatement of environmental problems [3,4]. Photocatalysis is anticipated to become in the coming years important also for selective organic synthesis [4]. In a more distant future thermal catalytic processes induced by heating with solcir radiation, together with photocatalytic processes may become important for environmentally friendly technologies of solar energy utilization [5-9]. 

It is anticipated that the new, environmentally friendly technology designed by Headwaters for H2O2 production will soon replace the current anthraquinone process because of the high activity, selectivity, and durability of the novel nanocatalyst.

Electrolysis is an environmentally friendly technology. Properly designed electrochemical processes which use a mass-free reagent (the electron without the need of additional chemicals at ambient temperature) do not produce unwanted effluents, they often do not need toxic compounds (such as CN ) and do not introduce hazards of their own. 

Since the 1980s, Filipovic has concentrated on developing environmentally friendly technologies. She is the co-inventor of a patented process known as Blue Bottle technology. This process is used... 

Several high-value niche markets drove early fuel cell technology development. These were the use of fuel cells for on-board electric power in space vehicles and to demonstrate that fuel cells are an efficient, environmentally-friendly technology for stationary on-site commercial power. 

Due to the requirement of obtaining enantiomerically pure products through environmentally friendly technologies, the development of new methods in asymmetric catalysis is becoming an important approach to asymmetric synthesis. Asymmetric hydrogenation is one of the most applied catalytic reactions for the... 

Among the separation techniques, liquid-liquid (solvent) extraction is one of the best-known, well-established, versatile, and easy to use. However, traditional extraction employs conventional organic solvents immiscible with water, which are typically volatile, flammable, and health hazardous. This makes extraction inappropriate for modern and future environmental-friendly technologies and analysis processes. Another problem with conventional solvents is that their number is rather limited, so it may be difficult to find fhe solvenf ideally suifed for a particular application (even considering solvent mixtures). 

In the last few years, further applications for enzymatic processes in textile finishing were developed and - very importantly - the necessary suitable enzymes were found. Large-scale production of such enzymes led to price reductions, which in turn led to more applications, as enzymes were found to be efficacious in the textile industry. Another major reason why enzymatic processes are becoming more popular is the increasing importance of environmentally friendly technologies due to customers demands or restrictions by law. 

Industrial (white) biotechnology is rapidly gaining momentum as a cost-effective and environmentally-friendly technology for producing bio-based chemicals, materials, and fuels in a safe and sustainable way from renewable resources. 

I should note that all projects will be implemented with close cooperation of the experienced foreign specialists using modem environmental friendly technologies.
