Anaerobic digestion of long-chain fatty acids (oleic, palmitic, stearic) with whey protein as the emulsifier

(Corresponding) Eftaxias A., Michailidis C., Diamantis V., Aivasidis A.
Topic: 
Environmental biotechnology and bioenergy
Long chain fatty acids are suitable for biogas production, however, they are often responsible for process inhibition, due to their high toxicity even at low concentrations. In this study, anaerobic co-digestion of whey protein emulsified with oleic, palmitic or stearic acid were examined in...Read more

Biogas upgrade via ex-situ technologies

Spyridonidis A., Vasiliadou I., (Corresponding) Stamatelatou K.
Topic: 
Environmental biotechnology and bioenergy
The biological upgrade of biogas to biomethane (CH4 > 90%) is a popular emerging technology, since the produced CO2 is not removed but is converted to biomethane using hydrogen (H2). The initial aim of the present study is the acclimatization of a microbial population derived from a typical...Read more

Direct upgrading of biogas produced by anaerobic digestion: preliminary results at laboratory scale

Bonaccorsi L., Fazzino F., Fotia A., Malara A., Pedullà A., (Corresponding) Calabrò P.
Topic: 
Environmental biotechnology and bioenergy
The present study investigated, at laboratory scale, the possibility of achieving biogas upgrading with a single step of treatment, namely without involving any pre- or post-treatment or multiple stage recirculation. In this respect, three commercial molecular sieves (i.e., Honeywell 13X, 4A, and...Read more
