TL;DR: It is evident from a literature survey of about 210 recent papers that low-cost sorbents have demonstrated outstanding removal capabilities for certain dyes, and chitosan might be a promising adsorbent for environmental and purification purposes.

TL;DR: The results suggested that the new process, which combined bioengineering and transesterification, was a feasible and effective method for the production of high quality biodiesel from microalgal oil.

TL;DR: A computer model to estimate the capital and operating costs of a moderately-sized industrial biodiesel production facility was developed and found the production cost of biodiesel was found to vary inversely and linearly with variations in the market value of glycerol, increasing by US dollar 0.0022/l (dollar 0.065/gal) for every US dollar0.01/lb change in oil cost.

TL;DR: An awareness of the various uses of the oil can be used to make a strong case for an increase in its production as a vital raw material for the chemical industries.

TL;DR: The highly efficient low cost and the rapid uptake of Cd(II) by NCRH indicated that it could be an excellent alternative for the removal of heavy metal by sorption process.

TL;DR: Studies were carried out on transesterification of Karanja oil with methanol for the production of biodiesel using optimized reaction parameters such as catalyst concentration, alcohol/oil molar ratio, temperature, and rate of mixing.

TL;DR: The results indicate that eucalyptus bark can be used for the removal of chromium and the feasibility and spontaneous nature of adsorption is indicated.

TL;DR: Under the characterization measurements investigated, it was found that the pore structures of the two biomaterials belong to a typical Type II, indicating that they should be basically characteristic of nonporous materials or materials with macropores or open voids.

TL;DR: Cassava wastewater proved to be a suitable substrate for biosurfactant biosynthesis, providing not only bacterial growth and product accumulation but also a surfactant that has interesting and useful properties with potential for many industrial applications.

TL;DR: Compared with conventional diesel fuel, diesel-biodiesel blends showed lower carbon monoxide (CO), and smoke emissions but higher oxides of nitrogen (NOx) emission, however, compared with the Diesel fuel, NOx emission was slightly reduced when EGR was applied.

TL;DR: The enzymatic digestibility of lime-treated corn stover was affected by the change of structural features (acetylation, lignification, and crystallization) resulting from the treatment, and the degree of crystallinity slightly increased from 43% to 60% with delignification because amorphous components (lignin, hemicellulose) were removed, but the increased crystallinity did not negatively affect the 3-d sugar yield of enzymatics.

TL;DR: The chemical composition of red seaweed Gracilaria cervicornis and brown seaweed Sargassum vulgare from Brazil was investigated and lipid concentrations were the lowest recorded chemical component and varied slightly between the two species.

TL;DR: The purpose of this paper is to review the available information on various attributes of fly ash and explore the possibility of exploiting them for agronomic advantage.

TL;DR: The results revealed that activation time gives no significant effect on the pore structure of activated carbon produced, however, the por characteristic of carbon changes significantly with impregnation ratio and carbonization temperature.

TL;DR: The fuel properties of mahua biodiesel so obtained complied the requirements of both the American and European standards for biodiesel.

TL;DR: The cause of seasonal failure of a nitrifying municipal landfill leachate treatment plant utilizing a fixed biofilm was investigated by wastewater analyses and batch respirometric tests at every treatment stage and high free ammonia (NH3-N) inhibited not only nitrite oxidizing bacteria (NOB) but also ammonia oxidizingacteria (AOB).

TL;DR: The data reveals that vermicomposting (using E. foetida) is a suitable technology for the decomposition of different types of organic wastes (domestic as well as industrial) into value-added material.

TL;DR: Molecular structure and ionic radius of dyes were found to be responsible for differences in their uptakes and the presence of carboxylic and amino (+ve) groups in RB could explain the lower sorption of RB compared to MB.

TL;DR: The sorption of Cu2+, Cd2+, Pb2+, and Zn2+ by a dried green macroalga Caulerpa lentillifera was investigated and the analysis with FT-IR indicated that possible functional groups involved in metal sorption by this alga were O-H bending, N- H bending,N-H stretching,C-N stretching, C-O, SO stretching, and S-O stretching.

TL;DR: If struvite were to be recovered from wastewater treatment plants worldwide, 0.63 million tons of phosphorus (as P(2)O(5)) could be harvested annually, reducing phosphate rock mining by 1.6%.

TL;DR: Microwave pyrolysis still preserved some of the functional groups of the initial sludge such as aliphatic and oxygenated compounds, whereas no heavy PACs were detected.

TL;DR: Co-composting of pig manure with sawdust was studied in order to characterize the organic transformation during the process, using both chemical and spectroscopic methods and indicated an increase in polycondensed structures and the presence of more stable organic matter in the mature compost.

TL;DR: The presence of light and heavy metal ions influenced the copper and cobalt uptake potential of crab shell and among several eluting agents, EDTA (pH 3.5, in HCl) performed well and also caused low biosorbent damage.

TL;DR: The application of a pretreatment to hydrolyze and dissolve lipids may improve the biological degradation of fatty wastewaters, accelerating the process and improving time efficiency.

TL;DR: There still remain some unclear technical and scientific aspects that are necessary for the improvement of the stability and reliability of anaerobic processes.

TL;DR: The experimental results showed that the pretreatment of the substrate plays a key role in the conversion of the wheat straw wastes into biohydrogen by the composts generating hydrogen.

TL;DR: In this article, the potential applications of poly-epsilicon-lysine (epsilon-PL) as food preservatives, emulsifying agent, dietary agent, biodegradable fibers, highly water absorbable hydrogels, drug carriers, anticancer agent enhancer, biochip coatings in the fields of food, medicine, agriculture and electronics are also discussed.

TL;DR: Four cyanobacterial strains, Cyanothece sp.

TL;DR: The overall rate of dye adsorption appeared to be controlled by chemisorption, in this case in accordance with poor desorption studies.

TL;DR: Isolation from petroleum contaminated sites using the screening protocol presented proved to be a rapid and effective manner to identify bacterial isolates with potential industrial applications.
