Biogas production from broiler manure, wastewater treatment plant sludge, and greenhouse waste by anaerobic co-digestion
Sarikaya, E.; Demirer, Göksel Niyazi (2013-07-01)
Inappropriate management of organic wastes can cause serious damage to the environment by polluting water and air, which can lower the quality of life. Ammonia and greenhouse gases (CH4 and CO2) emitted from the waste storage units can pollute the air. Inappropriate application of nitrogen and phosphorus on fields as manure can lead to eutrophication of surface water resources and pollution of soil and ground water. Conversion of the organic wastes to biogas through anaerobic digestion will, however, reduce...
Biogas production potential from cotton wastes
Isci, A.; Demirer, Göksel Niyazi (2007-04-01)
The anaerobic treatability and methane generation potential of three different cotton wastes namely, cotton stalks, cotton seed hull and cotton oil cake were determined in batch reactors. In addition, the effects of nutrient and trace metal supplementation were also investigated. To this purpose biochemical methane potential (BMP) experiments were performed for two different waste concentrations, namely 30 and 60g/l. The results revealed that cotton wastes can be treated anacrobically and are a good source ...
Biogas production from pistachio (Pistacia vera L.) processing waste
Celik, I.; Demirer, Göksel Niyazi (2015-10-01)
Turkey is the third largest producer of pistachio (Pistacia vera L.) after Iran and United States. Harvested pistachio nuts are covered with organic hull which is removed by de-hulling process. Most of the pistachio by-products which are produced during de-hulling process are considered as agricultural waste and often mixed with soil, to a lesser extent are used as feedstuff by local livestock farmers and a small portion is used as herbal medicine. Due to its high organic and phenolic content as well as hig...

Data for semicontinuous anaerobic digestion of sunflower heads were obtained in fermentors of 11 of effective volume, maintained at 55-degrees-C Experiments were carried out with a 2% sunflower head-water mixture for hydraulic retention times of 15, 10, and 8 days. Biogas quantities and compositions were measured each day until steady state was achieved. The steady state was achieved after three times of each hydraulic retention time (HRT). Gas productions of 0.180 m3/ with 62% CH4, 0.280 m3/m3.di...
