An Investigation of the Enhancement of Biogas Yields from Lignocellulosic Material using Two Pretreatment Methods: Microwave Irradiation and Steam Explosion

Sapci, Zehra; Morken, John; Linjordet, Roar (North Carolına State Unıv Dept Wood & Paper Scı, 2013)

Two pretreatment methods, microwave irradiation and steam explosion, were investigated in this work. The aim of the study was to investigate whether these methods would improve the biodegradability of wheat straw as a ...
Incorporation of fish by-product into the semi-continuous anaerobic co-digestion of pre-treated lignocellulose and cow manure, with recovery of digestate's nutrients

Estevez, Maria M.; Sapci, Zehra; Linjordet, Roar; Morken, John (Pergamon-Elsevıer Scıence Ltd, 2014)

Norway's fish processing industry generates large amounts of fish waste every year. The high-risk waste fraction with most of its oil removed has not yet been tested for energy production. The stability of an anaerobic ...
Semi-continuous anaerobic co-digestion of cow manure and steam-exploded Salix with recirculation of liquid digestate

Estevez, Maria M.; Sapci, Zehra; Linjordet, Roar; Schnurer, Anna; Morken, John (Academıc Press Ltd- Elsevıer Scıence Ltd, 2014)

The effects of recirculating the liquid fraction of the digestate during mesophilic anaerobic co-digestion of steam-exploded Salix and cow manure were investigated in laboratory-scale continuously stirred tank reactors. ...
