• has already been proven to be successful [4]. These examples show that photochemistry is a viable alternative to conventional chemistry approaches. In addition to specialty chemicals and wastewater treatment, photochemical pathways can also be used for methanol production [5], N2 fixation [6], and CO2

• . Photochemistry spans a number of reactions. For organic chemistry, 8000 photoreactions have been listed since 1975 [1]. Despite the huge portfolio, there is a lack of industrial applications of photochemistry. Van Gerven et al. listed five industrial applications of photochemistry in commercial wastewater

• microwave not only affects the selectivity but also the purity of the product [16]. Biosurfactants, an important class of compounds containing amide bonds, are potential substitutes of emulsifiers, which may be toxic [17][18]. Surfactants enter the environment in significant amounts through wastewater

• treatment plants or by direct release into watercourses. Their possible chronic effects on sensitive species and their potential environmental impact must be minimized, depending on the biodegradability and toxicity of the surfactants.
