THE CHALLENGES  OF GREENNESS ON FREIGHT TRANSPORTATION, THE CASE OF BRING LOGISTICS
âThe negative environmental impacts of transportation have gained wide recognition and are at the core of issues of sustainability, especially in urban areasâ (Rodrigue, Slack & Comtois, 2001). Many prior researches have been carried out on negative impact of transportation on environment. To minimize and to mitigate environmental concerns, green logistics and green transportation has been introduced in recent time. Logistics companies are becoming more flexible and slowly started moving towards green implementation. Implementation of this new strategy has definite challenges for logistics companies. In order to understand environmental problems caused by freight transportation and its challenges associated with green implementation, the aspect of greenness and its challenges were examined especially on the case of Bring Logistics. In this thesis, various modes of transportation and their environmental problems were discussed, city traffic and its consequences, implementation challenges, use of models, etc  The purpose of this research is to understand environmental problems caused by freight transportation and organisational challenges of green implementation in logistics firms.  To fulfill the purpose of this work, a qualitative research method was used with an inductive approach chosen for methodology. Materials were collected both primary and secondary sources and three types of interview were conducted i.e. face-face interview, interview through email and by phone. Eight interviews were conducted involving seven personalities from Bring Logistics Jönköping, Sweden.  In conclusion, a logistical structural changes were implemented as a model in order for the company to be successful in their green implementation. The problems caused by freight transportation were noise, air pollution and climate change. The challenges of green implementation were identified as financial, employees inflexibility, distribution delay, taxation and fuel pricing.The purpose of this research is to understand environmental problems caused by freight transportation and organisational challenges of green implementation in logistics firms
Silver Nanoparticles Synthesized Using Wild Mushroom Show Potential Antimicrobial Activities against Food Borne Pathogens
The present study demonstrates an economical and eco-friendly method for the synthesis of silver nanoparticles (AgNPs) using the wild mushroom Ganoderma sessiliforme. The synthesis of AgNPs was confirmed and the products characterized by UV-visible spectroscopy, dynamic light scattering spectroscopy and X-ray diffraction analysis. Furthermore, Fourier transform infrared spectroscopy (ATR-FTIR) analysis was performed to identify the viable biomolecules involved in the capping and active stabilization of AgNPs. Moreover, the average sizes and morphologies of AgNPs were analyzed by field emission scanning electron microscopy (FE-SEM). The potential impacts of AgNPs on food safety and control were evaluated by the antimicrobial activity of the synthesized AgNPs against common food-borne bacteria, namely, Escherichia coli, Bacillus subtilis, Streptococcus faecalis, Listeria innocua and Micrococcus luteus. The results of this study revealed that the synthesized AgNPs can be used to control the growth of food-borne pathogens and have potential application in the food packaging industry. Moreover, the AgNPs were evaluated for antioxidant activity (DPPH), for biocompatibility (L-929, normal fibroblast cells), and for cytotoxic effects on human breast adenosarcoma cells (MCF-7 & MDA-MB231) to highlight their potential for use in a variety of bio-applications
Scalable Synthesis of Hide SubstanceâChitosanâHydroxyapatite: Novel Biocomposite from Industrial Wastes and Its Efficiency in Dye Removal
A novel porous polymerâinorganic
hybrid biocomposite with
various functional groups (hide substance/chitosan/hydroxyapatite)
has been synthesized in simple, economic, and scalable process utilizing
leather industry solid waste and seafood industry waste composed with
hydroxyapatite. Physicochemical characterization of the material reveals
formation of composites with homogenous distribution of the constituents
in the material matrix. The composite is hard and porous (with 0.1632
cm3/g slit-shaped mesopores and micropores) having particle
sizes 40â80 ÎŒm and a BrunauerâEmmettâTeller
surface area of 55.54 m2/g. The material is polycrystalline
in nature with a fair amount of amorphous substance and less hydrophilic
in character than constituent polymers. The dye removal efficiency
of the material has been tested with two model dyes, namely, methylene
blue (MB) (cationic/basic dye) and sunset yellow (SY) (anionic/acid
dye). Optimum adsorptions of 3.8 mg MB (pH 12, RT â 27 °C)
and 168 mg of SY (pH 3, RT â 27 °C) have been found per
gram of the composite material. Langmuir isotherm and pseudo second
order rate models have been found to be the best-fit models to explain
the equilibrium isotherm and kinetics of the adsorption process for
both the dyes. However, higher and faster adsorption of SY in comparison
with MB indicated higher binding efficiency of the material toward
the acidic dye. Desorption of dyes from the dye-adsorbed material
was studied using a suitable eluent of appropriate pH and recycling
for five times showed without loss of efficiency. The prepared composite
showed very high dye removal efficiency toward four different commercially
used dyes (496 mg/g of Orange-NR, 477 mg/g of Red-VLN, 488 mg/g of
Blue-113 dye, and 274 mg/g of Green-PbS dye) from their individual
and cocktail solutions. It was also efficient to decolorize dye-bearing
tannery exhaust bath. Hence, waste materials generated during industrial
processes could be efficiently used for the decontamination of colored
wastewater produced by various industries

Green Synthesis of Endolichenic Fungi Functionalized Silver Nanoparticles: The Role in Antimicrobial, Anti-Cancer, and Mosquitocidal Activities
Green nanotechnology is currently a very crucial and indispensable technology for handling diverse problems regarding the living planet. The concoction of reactive oxygen species (ROS) and biologically synthesized silver nanoparticles (AgNPs) has opened new insights in cancer therapy. The current investigation caters to the concept of the involvement of a novel eco-friendly avenue to produce AgNPs employing the wild endolichenic fungus Talaromyces funiculosus. The synthesized Talaromyces funiculosus–AgNPs were evaluated with the aid of UV visible spectroscopy, dynamic light scattering (DLS), Fourier infrared spectroscopy (ATR-FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The synthesized Talaromyces funiculosus–AgNPs (TF-AgNPs) exhibited hemo-compatibility as evidenced by a hemolytic assay. Further, they were evaluated for their efficacy against foodborne pathogens Staphylococcus aureus, Streptococcus faecalis, Listeria innocua, and Micrococcus luteus and nosocomial Pseudomonas aeruginosa, Escherichia coli, Vibrio cholerae, and Bacillus subtilis bacterial strains. The synthesized TF-AgNPs displayed cytotoxicity in a dose-dependent manner against MDA-MB-231 breast carcinoma cells and eventually condensed the chromatin material observed through the Hoechst 33342 stain. Subsequent analysis using flow cytometry and fluorescence microscopy provided the inference of a possible role of intracellular ROS (OH−, O−, H2O2, and O2−) radicals in the destruction of mitochondria, DNA machinery, the nucleus, and overall damage of the cellular machinery of breast cancerous cells. The combined effect of predation by the cyclopoid copepod Mesocyclops aspericornis and TF-AgNPS for the larval management of dengue vectors were provided. A promising larval control was evident after the conjunction of both predatory organisms and bio-fabricated nanoparticles. Thus, this study provides a novel, cost-effective, extracellular approach of TF-AgNPs production with hemo-compatible, antioxidant, and antimicrobial efficacy against both human and foodborne pathogens with cytotoxicity (dose dependent) towards MDA-MB-231 breast carcinoma
