Abstract: The wastes and the by-products of food industrial technologies are suitable for bioenergy generating because of the high organic matter content.Anaerobic digestion is the eldest technology for waste stabilization and however by controlled decomposition a high value and marketable energy source can be produced.Whey is normally used as a component of dairy products or as an additive for food product.In our work we focused on another utilization method: biogas generating from membrane separated fractions i.e.: permeate and concentrate of whey.The effect of the pH, thermal, microwave pre-treatment and their combinations on the biogas yield were investigated.Our results showed that the applied pre-treatments had significant effect on biogas production.In consequence of the hydrolysis of large molecules the biodegradability of the pre-treated whey fractions was enhanced, therefore the biogas and methane production yield increased significantly.
