Evaluation of biogas yield from water leaf plant (Talinum triangulare) CIGR Journal
Ogunwande, Gbolabo Abidemi; Muritala, Adam O; Babalola, Waliu O.
The exploitation of plant materials for renewable source of energy in form of biogas is of growing interest. Water leaf (Talinum triangulare), an abundantly available underutilized herbaceous perennial plant in South-Western Nigeria was digested to assess its biogas yield. Water leaf (WL) and Water hyacinth (Eichhornia crassipes) alone, and mixtures of water hyacinth (WH) and WL at ratios 70:30, 50:50 and 30:70 (w:w dry basis) were digested to compare biogas yields. Fixed amount of cow dung was added to each treatment before digestion in batch-type anaerobic digesters for 70 days. The results of the study showed that feedstock mixture affected (p ≤ 0.05) pH and biogas yield. WL proved to be prolific in biogas as it yielded approximately six times greater...

Effects of Mixture Ratio of Cow Manure and Greenhouse Wastes on Anaerobic Co-digestion Process CIGR Journal
Yaldız, Osman.
The biogas production from the agricultural wastes is accepted as an eco-friendly solution for keep up with increasing energy demand in the world. The cow manure which is produced in every farm is readily available source for biogas production via anaerobic digestion. The main limitation for biogas production from manure is the inhibition of anaerobic microorganisms resulted from the high ammonia/ammonium content of manure. The co-digestion of manure with agricultural wastes is frequently applied to cope with this limitation. This study aims to investigate the biogas production from the co-digestion of cow manure and greenhouse residues in different mixing ratios as input materials. Tomato and pepper wastes from greenhouses were selected as co-substrates...
