“…Willow is characterized by a high C/N quota as well as low levels of buffering components and possibly also trace metals, essential for microbial activity, and thus without complementary material the biogas process would fail due to nutrient deficiency [61]. Still, willow has a high energy content per mass and can thus be used as a complement to less carbon-rich and more diluted material, such as manure [63,64]. Addition of willow to a manurebased biogas system would allow a higher organic load with only marginal effects on retention time and, consequently, result in increased volumetric gas yields and a more efficient use of digester volume.…”

An increasing interest to convert lignocellulosic biomass into biofuels has highlighted the potential of using willows for this purpose, due to its fast growth in short rotation coppice systems. Here, we use a mapping population of 463 individuals of a cross between Salix viminalis and S. viminalis × S. schwerinii to investigate the genetic background of different wood chemical traits, information of importance for breeding towards different uses of wood. Furthermore, using a subset of the mapping population, the correlation between biogas production and chemical traits was investigated. The phenotyping of wood was carried by Furriertransformed-Infrared spectrometry (FT-IR) and water content analysis. Quantitative trait loci (QTLs) analysis was used to identify regions in the genome of importance for the phenotypic variation of these chemical traits. We found 27 QTLs for various traits. On linkage group (LG) VI-1, QTLs for signals assigned to G-lignin, lignin, and the S/G ratio were collocated and on LG XIV we found a cluster of QTLs representing signals assigned to lignin, cellulose, hemicellulose, and water. The QTLs explained from 3.4 to 6.9% of the phenotypic variation indicating a quantitative genetic background where many genes influence the traits. For the biogas production, a positive and negative correlation was seen with the signals assigned to acetyl and lignin, respectively. This study represents a first step in the understanding of the genetic background of wood chemical traits for willows, information needed for complementary studies, mapping of important genes, and for breeding of varieties for biofuel production purposes.

“…Due to the versatility of OW, the anaerobic co‐digestion of OW is commonly used to improve the individual BP. Literature related to OW and their co‐digestion have found to be beneficial for BP including FVR and sewage sludge, chicken manure and microalgae, OFMSW and FVR, sorghum and cow manure, animal manures and lignocellulosic residues, farm wastes, pig manure and dewatered sewage sludge, cattle slaughterhouse wastes, and OFMSW and MSW incinerator ash . On the other hand, factors affecting AD include pH, temperature, inoculum, substrate/inoculum (S/I) ratio, substrate concentration, substrate C/N ratio, substrate particle size, substrate pretreatment, substrate mixing, hydraulic retention time (HRT) or SRT, organic loading rate (OLR), substrate characteristics, trace elements, etc .…”

Agricultural organic wastes (AOW) have the potential to provide bioenergy particularly found in biogas by anaerobic digestion (AD). In this study, the biogas production (BP) of AOW was obtained by batch AD with anaerobic digesters (500 mL) at 35°C incubator. The results showed that BP values in terms of volatile solids (VS) from rice husk, rice straw, flower residues, fruit and vegetable residues, wasted oyster shell residue (WOSR), fishery residues, livestock and poultry manures, livestock and poultry slaughter wastes (LPSW), and eight equally mixed wastes (EEMW) were 84.03, 193.36, 153.32, 76.27, 150.48, 63.26, 169.63, 615.74, and 172.83 mL/g VS, respectively. LPSW showed the highest μm of 16.99 mL/g VS‐d, the highest BP of 615.74 mL/g VS and the highest bioconversion efficiency of 65.98% compared to the other organic wastes. BP from the most AOW in Taiwan by AD was estimated to be 768,567,753 (743,522,223, excluding WOSR) m3/year. The annual BP of 768,567,753 m3/year of the eight total major AOW by AD was lower (∼20.11%) than 961,989,781 m3/year of the EEMW by anaerobic co‐digestion. Result also showed that modified Gompertz equation was suitable to describe BP accumulation and BP rate.

“…Cattle manure contains nitrogen, phosphate and potash (4, 2 and 4 kg m −3 ). 2 Anaerobic digestion is a suitable biological treatment which is widely used to convert organic wastes to biogas and fertilizers. 3 Nevertheless, the effluent of the anaerobic digestion process still remains very high in nitrogen and phosphorus contents which should be eliminated prior to discharge.…”

BACKGROUND: In this study, the feasibility of an aerobic granular sequencing batch reactor (AGSBR) for elimination of nutrients at low dissolved oxygen (DO) level was investigated. It was fed by a mixture of treated and raw cattle manure wastewater. The behaviour of the AGSBR was assessed at different chemical oxygen demand (COD)/NH 4 + -N ratios, feeding strategies (dump-fill and slow-rate feeding) and hydraulic retention times (24, 32 and 48 h). For a duration of 140 days, the capability of the AGSBR for reducing COD, ammonia and total phosphorus (TP) contents was studied. At DO concentrations of 0.3-1.0 mg L −1 , the effect of different COD/NH 4 + ratios (100:3-100:10) was evaluated. RESULTS:A COD/NH 4 + -N ratio of 100:10 resulted in higher nitrification rate (0.0714 gN gMLVSS −1 day −1 ) compared to a ratio of >100:3 (0.0175 gN gMLVSS −1 day −1 ). The active granular sludge in dump-filling mode revealed better settling properties compared to the slow feeding rate. Microscopic observation of aerobic granules showed that the core of granules was dominantly occupied by filamentous microorganisms. Finally, at optimum conditions, removal efficiencies of NH 4 + -N, TP and COD were 99.9, 99 and 79%, respectively. CONCLUSIONS: Applying the AGSBR at low DO is promising as a cost-effective technique for the secondary treatment of livestock wastewaters. /jctb 60.5% when COD/TP was changed from 54:1 (run 77) to COD/TP of 133:1 (run 82). Besides, TP removal efficiency reached to its maximum level when the steady state occurred in ending runs. This might be due to the full dominance of phosphate-accumulating
