Many agricultural and industrial wastes contain high levels of easily biodegradable materials. Thus they are ideal candidates for anaerobic digestion who is an attractive waste treatment practice in which both pollution control and energy recovery can be achieved which can represent an alternative fuel sources. Biodiesel (fatty acid methyl esters) produced by the process of trans-esterification of vegetable oils or animal fats with methanol are an alternative fuel sources and potential substitutes for petroleum-based diesel fuels.

The production of biodiesel provides a relatively large amount of co-products and waste, crude glycerol is the main by-product of the biodiesel industry. In general, about 10 kg of crude glycerol is produced per 100 kg of biodiesel. Despite the many applications of pure glycerol in the pharmaceutical, food and cosmetic industries, the process of refining crude glycerol for high purity remains too expensive.

In this work, we developed a separation technique, according to an oriented process for facilitated extraction through polymer inclusion membranes (PIMs), based on thermoplastic polymer as a mechanical support and some extractive agents for the selective extraction of glycerol....
