Biomass is defined as organic matter from living organisms represented in all kingdoms. It recognized to be an excellent source of proteins, polysaccharides and lipids and, such, embodies a tailored feedstock for new products processes apply green industries. The industrial focused on the valorization terrestrial biomass are well established, but marine sources still represent untapped resource. Oceans seas occupy over 70% Earth’s surface used intensively worldwide economies through fishery...
Biological nutrient removal from wastewater to reach acceptable levels is needed protect water resources and avoid eutrophication. The start-up of an anaerobic ammonium oxidation (anammox) process scratch was investigated in a 20 L sequence batch reactor (SBR) inoculated with mixture aerobic sludge at 30 ± 0.5 °C hydraulic retention time (HRT) 2–3 days. use NH4Cl, NaNO2, reject as nitrogen sources created different salinity periods, which the anammox performance assessed: low (<0.2 g...
Paulownia tomentosa, a woody plant that is widely found in Pakistan and other regions of the world, was used as raw material to prepare activated carbon using chemical physical activation methods. Adsorption dyes- acid red 4 methylene blue onto prepared were analyzed by batch experiments. The impacts different adsorption parameters such pH, temperature, contact time, initial dye concentration adsorbent dosage also evaluated. Equilibrium data fitted into various isotherm models as: Langmuir,...
Pd–Ni nanoparticles supported on activated carbon (Pd–Ni/AC) were prepared using a phase transfer method. The purpose of synthesizing ternary composites was to enhance the surface area synthesized nanoparticles, as they have low area. resulting composite characterized by scanning electronic microscopy (SEM), X-ray diffraction (XRD) and energy-dispersive spectroscopy (EDX) for investigating its morphology, particle size, percentage crystallinity elemental composition, respectively. XRD data...
The risk related to embankment dam breaches needs be evaluated in order prepare emergency action plans. physical and hydrodynamic parameters of the flood wave generated from failure event correspond various breach parameters, such as width, slope, formation time. This study aimed simulate scenario Yabous (northeast Algeria) analyze its influence on areas (urban natural environments) downstream dam. simulation was completed using sensitivity analysis method assess impact flooding break...
For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in masses through their accumulation, sorting and recycling. Important political technical challenges are involved, especially respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used most economic sectors. However, questions of recycling the contemporary world cannot be solved without knowing material, which can...
The catalytic activity of Pd/ZrO2 was studied in terms the degradation rhodamine-B dye presence hydrogen peroxide. prepared by impregnation method, calcined at 750 °C and characterized XRD, SEM EDX. catalyst showed good for 333 K, using 0.05 g during 5 h. reaction kinetics followed pseudo-first order kinetics. Freundlich, Langmuir Temkin isotherms were applied to data best fit obtained with Freundlich isotherm. Thermodynamic parameters, like ΔH, ΔG ΔS also calculated. negative values ΔH...
Implementation of construction works on weak (e.g., compressible, collapsible, expansive) soils such as peatlands often is limited by logistics equipment and shortage available applicable materials. If preloading or floating roads geogrid reinforcement piled embankments cannot be implemented, then soil stabilization needed. Sustainable in an environmentally friendly way recommended instead applying known conventional methods pure cementing excavation a single replacement soils. Substitution...
In this study, activated carbon (AC) and magnetic (MAC) were prepared from Dalbergia sissoo sawdust for the removal of antibiotic Azithromycin (AZM) aqueous solution. The effect initial concentration, contact time, pH, adsorbent dosage, temperature investigated both adsorbents. optimum AZM pH adsorbents dosages found to be 80 mg/L, 120 min, 6 7 (pH, respectively, AC MAC), 0.1 g (for respectively. isothermal data sets experiments correlated well with Langmuir isotherm model, while kinetic...
In this study, Ailanthus altissima sawdust was chemically activated and characterized by Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR), Energy Dispersive X rays (EDX), surface area analyzer. The used as an adsorbent for the removal of azo dye; Acid Yellow 29 (AY 29) from wastewater. Different kinetic equilibrium models were to calculate adsorption parameters. Among applied models, more suitable model Freundlich with maximum capacities 9.464, 12.798, 11.46 mg/g at 20...
Mangroves play a crucial role in maintaining the stability of coastal regions, particularly face climate change. To gain insight into associations between change and mangroves, we conducted bibliometric research on global indexed database Web Knowledge, Core Collection. A total 4458 literature were analyzed based information article metadata through scientometric analysis citation as well cluster analysis. Results suggest that countries such USA, Australia, China, India, Brazil are showing...
Landfill mining is an alternative technology that merges the ideas of material recycling and sustainable waste management. This paper reports a case study to estimate value landfilled materials their respective market opportunities, based on full-scale landfill project in Estonia. During project, dump site (Kudjape, Estonia) was excavated with main objectives extracting soil-like final cover function methane degradation. In total, about 57,777 m 3 processed, particularly uppermost 10-year...
Contamination associated with metals is a critical concern related to their toxicity, persistence, and bio-accumulation. Trace elements are partitioned into several chemical forms, which some more labile during fluctuations in the environment. Studying distribution of between different fractions contributes assess bioavailability identify potential risk contamination surrounding environments. This study concerns speciation (Pb, Cr, Ni, Zn Fe) from sediments coming out Malmfjärden bay,...
Growing global production leads to continuing generation of waste, part which still ends its life cycle in landfills and dumps. Despite the efforts waste reuse recycling self-degradation, existing old dumps remain a huge challenge for future. The majority can be identified as non-sanitary designated or former dumps, meaning hills fields abandoned garbage degraded inert masses without any with little aftercare maintenance. In contrast, term ‘landfill’ refers legally organized disposal sites...
