A process for producing biodiesel has been invented by first extracting lipids from the sludges generated during primary and / or biological treatment of municipal, agricultural, and industrial wastewaters using primary, secondary, and tertiary treatments followed by the transesterification of the extracted lipids using transesterification conversion into alcohol-based esters. The resulting products from this process include biodiesel, glycerol, lipid-free proteins, various other useful chemicals and an aqueous-based substrate well suited for optimized digestion within subsequent biological digestion (either aerobic or anaerobic). The lipids extracted from the sludges containing high levels of microorganisms are phospholipids which can also be directly used as lecithin. The extraction of the lipids from the sludges will be performed using chemical extraction techniques with the transesterification of the extracted lipids accomplished using basic, acidic, and / or a combination of the two transesterification techniques.

Disclosed are multilayered liposomes for transdermal absorption and a method of preparing the liposomes. The multilayered liposomes are prepared using a mixture of oil-phase components comprising squalane, sterols, ceramides, neutral lipids or oils, fatty acids and lecithins, is 200 to 5000 nm in particle size, and is capable of entrapping a physiologically active substance. The multilayered liposomes entrap a larger amount of a physiologically active substance and are structurally stable when encapsulating the physiologically active substance, compared to unilamellar liposomes. Also, they are prepared by a simple and cost-effective process not using a high-pressure homogenizer but using a general homo mixer. Further, since the multilayered liposomes are prepared in a larger size than the intercellular spaces in the stratum corneum, they overcome the tension of surrounding cells when passing through the intercellular spaces and are thus able to penetrate into the dermal layer, compared to nano-sized unilamellar liposomes. Thus, the multilayered liposomes are useful for enhancing the transdermal absorption of physiologically active substances.
