TL;DR: Steam pretreatment, lime pret treatment, liquid hot water pretreatments and ammonia based Pretreatments are concluded to be pretreatment with high potentials, providing an improved accessibility of the cellulose for hydrolytic enzymes.

TL;DR: The basic concepts of the composting process and how manure characteristics can influence its performance are explained and a summary of those factors such as nitrogen losses, organic matter humification and compost maturity which affect the quality of composts produced by manure composting is presented.

TL;DR: A triangular graph based on the composition in monounsaturated, polyunsaturated and saturated methyl esters was built in order to predict the critical parameters of European standard for whatever biodiesel, known its composition.

TL;DR: Intensive animal production areas need suitable manure management, aiming to export and to redistribute the excess of nutrients from manure and to optimize their recycling, to avoid over-fertilization.

TL;DR: In this paper, the authors investigate changes in substrate chemical and physical features after pretreatment, several characterizations were performed on untreated (UT) corn stover and poplar and their solids resulting pretreatments by ammonia fiber expansion (AFEX), ammonia recycled percolation (ARP), controlled pH, dilute acid, flowthrough, lime, and SO(2) technologies.

TL;DR: The results showed that the lipid accumulation from logarithmic phase to stationary phase of N. oculata NCTU-3 was significantly increased, and this microalga was suggested to grow in the semicontinuous system aerated with 2% CO(2) and operated by one-day replacement.

TL;DR: It is found that the formation of CO is enhanced with elevated temperature and residence time, while slight change is observed for the yield of CO(2).

TL;DR: Evaluation of six different wheat straw-to-biofuel production scenaria showed that either use of wheat straw for biogas production or multi-fuel production were the energetically most efficient processes compared to production of mono-fuel such as bioethanol when fermenting C6 sugars alone.

TL;DR: Two high-throughput systems are presented based on extinction or scattered light measurements and results indicate that among the ionic liquids tested EMIM Ac is the most efficient for dissolving cellulose, and it was observed that AMIM Cl is themost effective ionic liquid for Dissolving wood chips.

TL;DR: Geobacter-like species with the most representative Geobactersulfurreducens PCA(T) were integral members of the bacterial community in all MFCs except for the propionate-fed system, and there was no single dominant bacterial species.

TL;DR: A controlled and up-scalable route for the biosynthesis of silver nanopartilces (NPs) mediated by fungal proteins of Coriolus versicolor has been undertaken for the first time and the amino groups were bound to the particles, which was accountable for the stability of NPs.

TL;DR: Utilization of eggshell as a catalyst for biodiesel production not only provides a cost-effective and environmental friendly way of recycling this solid eggshell waste, significantly reducing its environmental effects, but also reduces the price of biodiesel to make biodiesel competitive with petroleum diesel.

TL;DR: Hemicellulose removal was found to be as critical as lignin sulfonation for cellulose conversion in the SPORL process, establishing a novel process using sulfite pretreatment to overcome recalcitrance of lignocellulose (SPORL) for robust and efficient bioconversion of softwoods.

TL;DR: The performance of MFC, exposed to variation in temperature, pH, external resistance and influent chemical oxygen demand, was investigated in the terms of coulombic efficiency (CE) and COD removal efficiency, while treating a synthetic wastewater.

TL;DR: Shea meal exhibited a complex char combustion behaviour indicating that there may be two distinct types of char derived from fibrous and woody components in the original material.

TL;DR: It was indicated that the collected liquid in the second condenser with HZSM-5 had high qualities and might be used as transport oil.

TL;DR: The microalgae, Chlorella sp.

TL;DR: Review of published research on the conversion of switchgrass into bioethanol and other value-added products finds increased biomass yields, optimization of feedstock composition for bioenergy applications, and efficient pentose fermentation to improve ethanol yields.

TL;DR: This article points out the significant biases in estimating GHG balances of biofuels stemming from modelling choices about system definition and boundaries, functional unit, reference systems and allocation methods, and some recommendations for basing the estimation of energy and GHG checks on principles such as transparency, consistency and accuracy are come out.

TL;DR: It is argued that in view of the fact that recovered nutrients will become of increasing economic and ecological value, this new conceptual design for the treatment of "used water" will become feasible in the next decade.

TL;DR: The apparent temperature independence and the strong pH dependence of the amount of metal ions adsorbed along with moderate mean free energies of biosorption altogether indicate that bios orption of Cd(2+) and Cu(2+ by wheat straw might follow a chemisorption mechanism.

TL;DR: An overview on the impact of landfilling (and its various alternatives) and composting on greenhouse gas emissions taking into account streamlined life cycle activities and the decomposition process is provided.

TL;DR: Dalbergia sisoo, generally known as sesame wood or rose wood is mainly used in the furniture and wastage of the same is used as a biomass material in the present gasification studies.

TL;DR: A developed consortium-GR completely decolorized an azo dye Scarlet R under static anoxic condition with an average decolorization rate of 16,666 microg h(-1); which is much faster than that of the pure cultures.

TL;DR: The IL 1-ethyl-3-methyl imidazolium diethyl phosphate ([EMIM]DEP) shows promise as pretreatment solvent for wheat straw, although its cost should be reduced and in-depth exploration of this subject is needed.

TL;DR: SARSH by Trichosporon fermentans is a promising strain for microbial oil production and thus biodiesel preparation from agro-industrial residues, especially lignocellulosic materials.

TL;DR: The various anaerobic treatments of POME and factors that influence the operation of anaerobia treatment are discussed and the POME treatment at both mesophilic and thermophilic temperature ranges are analyzed.

TL;DR: Methane production was significantly higher and no effect on the characteristics of the digested material was noticed as compared to digesting sewage sludge alone, and at higher grease trap sludge additions, degradation was not complete and methane production either remained the same or decreased.

TL;DR: In this work, palm and coir fiber reinforced polypropylene bio-composites were manufactured using a single extruder and injection molding machine and 30% fiber reinforced composites had the optimum set of mechanical properties.

TL;DR: A predictive calculation was established using the experimental results obtained for the three components separately to evaluate the carbonization and activation yields and their respective contributions to the chars and to the subsequent activated carbons of various precursors in term of weight fraction and showed that lignin can be considering as being the major contributor of all chars andactivated carbons.
