SEED PRIMING OF FENUGREEK SEEDS WITH SILICA NANOPARTICLES: ENHANCED GROWTH ECONOMICS AND SUSTAINABLE AGRICULTURAL PRACTICES

by MN N.b. seppiraj N. Madheswaran N.

Nanomaterials in the environment: applications and effects

Background: This study aimed to evaluate the impact of various concentrations of nano-silica on the germination process of fenugreek seeds. The agro-waste materials such as rice husk, corn cobs and bagasse were used as a precursor for synthesizing nano-silica. Moreover, their formation was confirmed...

Removal of toluene from Air- scream using semi industrial two-phase bioscrubber with cutting oil: An intervention study

by Golbabaei F. Karimi A. Rahimimoghadam S. Nourmohammadi M.

Issue 6

Environmental Health

Toluene is a monocyclic aromatic compound that finds widespread use in various industrial processes. Due to its harmful effects on human health and environment, this study aimed to remove toluene from the air stream using a two-phase bioscrubber. The bioscrubber design consisted of an absorption...

Issue 3

Solid Waste Management

The rapid growth of infrastructure leads to industrial waste accumulation and natural resource depletion, raising the need for sustainable solutions. When zinc is refined, a significant amount of non-biodegradable material called jarosite (JS) is generated, requiring proper environmentally friendly...

Senatore Vincenzo et al. View all

Issue 2

Air Quality

Volatile Organic Compounds (VOCs) are toxic for the environment and human health and their tendency to readily volatilize in the atmosphere can lead to problems connected to odours annoyance. Conventional VOCs gaseous emissions treatments entail the application of chemical-physical processes, only...

CEST2017 - Electric and electronic waste

Technological development combined with a rapid and global market penetration has led to high volumes of Waste Electrical and Electronic Equipment (WEEE). Simultaneously, the use-phase has become shorter resulting in an annual growth rate of WEEE between 3-5%, which makes WEEE one of the fastest...

Antonio Bula et al. View all

Issue 6

Sustainable Energy

A Computational Fluid Dynamics (CFD) simulation using CFX, ANSYS 11.0, has been carried out using a multiphase flow model with an Eulerian-Eulerian approach for an airlift column photobioreactors (PBR). Transient simulations were performed for three inlet air flow, 2, 3 and 5 l/min. The contours for...

Increase of biogas production through co-digestion of lipids and sewage sludge

by

Noutsopoulos C., Mamais D., Antoniou K. and Avramides C.

Issue 2

General

The aim of this study was to assess the feasibility of co-digesting lipids originated from domestic wastewater along with sewage sludge. Three lab-scale single stage mesophilic anaerobic digesters were operated under a constant hydraulic retention time (15 days). One system (C) was fed on a daily...

Behaviour of trace elements during the naturel evaporation of sea water: case of solar salt works of Sfax saline (S.E. of Tunisia)

by

Amdouni R.

Issue 1

General

We have carried out a geochemical study on the behaviour of certain trace elements during the evaporative concentration of free brines (salinity from 41 to 400 ‰) of the solar salt works of Sfax saline (S.E of Tunisia). The elements concerned by this survey are Zinc, Cadmium, Manganese, Molybdenum...

Effect of growth conditions on biosorption of cadmium and copper by yeast cells

by

Anagnostopoulos V.A., Symeopoulos B.D. and Soupioni M.J.

Issue 3

General

The dependence of Cd(II) and Cu(II) uptake by yeast cells on the age and temperature of cell culture was studied. Saccharomyces cerevisiae, Kluyveromyces marxianus and Debaromyces Hansenii were chosen as typical yeasts, while Cd(II) and Cu(II) as typical metal pollutants. Our results revealed that...
