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.

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.

XLII-5, pp. 773-779, 2018.[Abstract]


<p>Urbanization is the process by which towns and cities are formed and become larger as more and more people begin living and working in central areas. According to 2001 census, the urban population of the country was 286.11 million, living in 5161 towns, which constitutes 27.81% of the total country's population. However, the same as per 2011 census has risen to 377.16 million viz. 32.16% of the total country's population and the number of towns has gone up to 7935. The rate of urban growth in the country is very high as compared to developed countries, and the large cities are becoming larger mostly due to continuous migration of population to these cities. India's current urban population exceeds the whole population of the United States, the world's third largest country. By 2050, over half of India's population is expected to be urban dwellers. This creates enormous pressure on existing urban infrastructure.</p>

<p>Urbanization trend in the State of Kerala shows marked peculiarities. The main reason for urban population growth is the increase in the number of urban areas and urbanization of the peripheral areas of the existing major urban centers. However, unlike the other parts of the country the Urbanization in Kerala is not limited to the designated cities and towns. The difference between rural and urban agglomerations is very negligible as far as Kerala is concerned. The Kerala society by and large can be termed as urbanized. Kerala has been witnessing rapid urbanization since 1980.</p>

<p>The present study, is an attempt to analyses the extent of land use/ land cover changes in the Municipality over the years from 2012 to 2017 and land surface variation over the years from 2000 to 2017.The land use/ land cover pattern of 2012 to 2017 was extracted from High resolution images of the study area were downloaded from Google Earth API and the Land Surface Temperature changes were analyzed from the thermal bands of the Landsat Imageries.</p>

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.

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 »»

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. 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.

<p>A hydroponics experiment was conducted to examine the phytofiltration of Cd by Limnocharis flava (L.) Buchenau grown in low-level Cd-contaminated water. For this, 45 d old seedlings of L .flava were transferred to a floating-support culture system containing nutrient solution spiked with four levels of Cd (0.5, 1, 2 and 4 mg l(-1)) and were separately harvested after 3, 7, 21 and 30 d. After 30 d harvesting, the percentage removal of Cd from the above four treatments reached up to 98, 96, 95 and 93%, respectively. Interestingly, all treatments had higher growth rate than control at 95% confidence level and plants still remained healthy at 4 mg l(-1) Cd exposure. The bioaccumulation study showed a linear relationship of Cd (R(2)=0.896-0.999) in all plant parts with the exposure time (3-30 d) and Cd concentrations in hydroponics system (0.5-4 mg l(-1)). Although, the root of L. flava had higher Cd concentration than leaf and peduncles, the total Cd concentrations in aerial plant parts were higher than the roots. The maximum bioconcentration factor (BCF) and translocation factor (TF) value of L. flava were calculated as 984.42 and 1.43, respectively. Estimated Cd accumulation capacity of L. flava per unit area (m(2)) was found to be in the range of 218. 35-1698.92 mg m(-2).The experimental results demonstrated that L. flava is a suitable candidate for the phytofiltartion (>93%) of Cd from low-level Cd-contaminated water.</p>

Nano Science and technology is an emerging area of research all over the globe because of the peculiar properties make it as a successful candidate in different cross cutting fields with multiple applications. The silver nanoparticles has much importance and widely employed in our day to day life as it exhibits immense potential antimicrobial activity against wide variety of pathogenic microorganisms and henceforth used commonly in medicines, organ implants, theatre products and pharmaceutical products. There are several traditional methodologies for the synthesis of nanoparticles, but all are expensive, time consuming, needs sophisticated equipment’s, chemicals and contaminate the environment. In the current work, we have approached the preparation of nanoparticles following green protocol with the leaf extract from a medicinal plant, Hydnocarpus pentandra. The silver nanoparticles prepared were characterized using UV-Vis Spectroscopy and Scanning Electron Microscopy. The antimicrobial activities where tested for gram negative (Escherichia coli) and gram-positive (Salmonella aureus) microorganisms. The method that we used here is simple, cheap, sustainable and non-poisonous to non-target organisms and does not cause any harm to environment. The larvicidal activity against mosquito larvae were assessed as per World Health Organization Standards. The nanoparticles synthesized exhibits excellent antimicrobial and anti larvicidal activities. We have come up with a novel technique for the synthesis of nanoparticles following green conduit, which is viable, simple, eco-friendly, cost effective, and have explored its applications in different fields.
