One of the options on which we zeroed in was utilization of weeds for generating energy as biogas via anaerobic digestion. This study makes an attempt to utilize some noxious aquatic weeds as a feedstock in High Solid Anaerobic Digesters (HSADs) for the recovery of energy. The specific objectives of the study were to fabricate lab scale HSADs for the digestion of organic fraction of some common noxious aquatic weeds and to evaluate the suitability of it as a feed stock in Anaerobic Digesters and the recovery of energy in terms of biogas. The findings indicate 4.873% of dry solids loss and 96.32% degradation of volatile solids at the end of the experiment for Typha latifolia with a total biogas yield of 14,175 ml and resulted into a total of 83,609 m3/m3digester volume and 4.168% of dry solids loss and 92.46% degradation of volatile solids at the end of the experiment for Pistia stratiotes with a cumulative biogas yield of 17,570 ml and resulted into a total of 83,609 m3/m3in 30 days. The performance of the reactors is similar with the values reported in earlier works. This waste utilization forms a sustainable solution for the management of organic fraction of municipal solid waste. Also the slurry from the bioreactor can be utilized as a bio fertilizer.

Silver nanoparticles were green synthesized using different plant substrates like Phyllanthus niruri, Curcuma angustifolia, utrica dioica etc were characterized with surface plasmon resonance (SPR) ultraviolet spectroscopy (UV–vis). The fresh biologically synthesized silver nanoparticles were turned to colorless, accompanying the broadening and blue shifting of SPR band upon the addition of mercuric ions into the medium and hence paved way towards the detection of mercury and hence led towards the development of cost effective colorimetric sensors. Moreover the larvicidal potential of these green synthesized silver nanoparticles were evaluated as per WHO standards.

This paper describes the dramatic success in the eco-restoration of a heavy-metal contaminated open garbage dump at the Amrita Institute of Medical Sciences (AIMS), a 1450-bed super-specialty hospital located in Kochi, Kerala, India. Today, the hospital caters to over 10 lakh patients annually. Inspired by our Chancellor’s vision of zero-waste, the hospital undertook its journey with a view to also reducing massive greenhouse gas emissions that result from improper handling of waste. Today, the hospital manages its municipal solid waste on an industrial scale, composting some eight metric tonnes of organic waste daily This case study outlines the path followed to achieve zero-waste. Alongside, the rehabilitation of a former dump site is described in detail at this very site are carried out all composting operations of AIMS. Within three years of the restoration activities, heavy metal concentrations in the contaminated soil reduced drastically There was relatively low uptake of the heavy metals by the plants; however, they might have been crucially responsible for providing a favorable environment for soil restoring microorganisms in their rhizosphere. Observable habitat-restoration continues at the site, including the return of birds and insects and other wildlife, making this an ideal site for further research and demonstration for community awareness and education.

This paper describes the dramatic success in the eco-restoration of a heavy-metal contaminated open garbage dump. A number of heavy metals (As, Cd, Cu, Co, Pb, Hg, Cr) were detected in the soil and river sediment at the site. The main restoration activities included mulching, surface-addition of compost and fresh soil and phytoremediation using vetiver and other plants. Within three years of the restoration activities, heavy metal concentrations in the contaminated soil reduced drastically. There was relatively low uptake of the heavy metals by the plants; however, they might have been crucially responsible for providing a favorable environment for soil-restoring microrganisms in their rhizosphere. Observable habitat-restoration continues at the site, including the return of birds and insects and other wildlife, making this an ideal site for further research and demonstration for community awareness and education.

Cost effective chemosensors were developed from green synthesized silver nanoparticles using Leucas indica and were characterized with surface Plasmon Resonance (SPR) UV Spectrometry. The sensitivity and selectivity of green synthesized silver nanoparticles towards transition metal ions and alkaline earth metals were studied. Applications such as antimicrobial activity and the ability of formed stable nanoparticle to act as chemosensors are also studied. UV studies confirmed the presence of silver nanoparticles by their characteristic peak in range of 436-446nm. Ag NPs also showed antimicrobial activities with gram negative (Escherichia coli) microorganisms.

Green synthesis of nanoparticles has become a prominent zone of attention in the field of nanotechnology, as it is a nontoxic, economically feasible and green approach. In the present work we have developed an eco-friendly and zero cost method for the synthesis of silver nanoparticles using common a bio waste banana blossom peel. The well-known characteristic phenomenon of surface Plasmon resonance (SPR) has been exploited towards the characterization of the green synthesized nanoparticles. The aforementioned nanoparticles were characterized by UV spectroscopy and the behaviour of these particles towards naked eye detection of metal ions were observed. The sensitivity of the nanoparticles towards the detection of metal ions was carefully monitored by the shift in the SPR band. Moreover the larvicidal potential of these green synthesized silver nanoparticles were evaluated as per WHO standards. The synthesized silver nanoparticles were found to be an effective antibacterial agent against Gram negative bacteria- E.coli . The method we followed for the synthesis of silver nanoparticles is economically feasible as well as environment friendly and also capable of rapid synthesis of nanoparticles at ambient conditions.

The well known characteristic phenomenon of surface Plasmon resonance (SPR) has been exploited towards the characterization of the green synthesized nanoparticles. The nanoparticles were characterized by UV spectroscopy and the behavior of these particles towards naked eye detection of metal ions were observed. The sensitivity of the nanoparticles towards the detection of metal ions were carefully monitored by the shift in the SPR band.

The chemical composition, nutritive value and trace element profiles of Limnocharis flava, an emergent aquatic weed during its different growth stages was determined to evaluate as possible cattle feed. Samples were analyzed at three progressive morphological stages of the plant, pre-flowering, flowering and post-flowering. The moisture content, dry matter (DM), ash content, crude protein (CP), ether extract (EE), crude fiber (CF), nitrogen free extract (NFE) and mineral constituents like sodium (Na+) potassium (K+), calcium (Ca2+), phosphorous (P) and trace elements like iron (Fe2+), copper (Cu2+), manganese (Mn2+), zinc (Zn2+), lead (Pb2+), chromium (Cr2+ ) nickel (Ni+) and cadmium (Cd+) contents were analyzed. The moisture content, organic matter (OM), acid detergent fiber content increased during maturation, while CP and EE were found decreased with increased growth stage. Only slight fluctuations occurred in Calcium, Potassium, Phosphorous and Sodium contents. The highest values for crude protein, fiber content, NFE and EE were observed at the flowering stage. These plant posses several characteristics which makes it a nutritious feed suitable for domestic livestock, and is recommended to use L.flava, particularly at the flowering stage of growth. More »»

Green nanotechnology has gained momentum in the recent years because it couples the immense applications of nanotechnology with the principles of green chemistry so that the toxic effects of nanotechnology stands nullified. The environmental as well as health issues of nanotechnology has only been addressed in the recent times and since then the green pathway towards the synthesis of nanoparticles has gained immense attention. The novel phenomenon of surface Plasmon resonance exhibited by metallic nanoparticles has been exploited and silver nanoparticles were prepared from biowastes like cashew peel, tapioca peel, banana bosom peel etc which would otherwise appear as waste in and around the processing centers. The aforementioned nanoparticles were characterized by UV spectroscopy and the behavior of these particles towards naked eye detection of selected heavy metal ions like nickel, cadmium,lead and mercury were observed.
