The original application was registered suo-motu based on the news item titled "Nayar …
ICI, a UK-based company, is developing an environmentally-sound paint for households that replaces up to 25 per cent of the petroleum-based chemicals now used in paints. The paint will use starch derived from crops including potatoes, wheat and maize. At present, interior paints use vinyl and acrylic derived from petroleum-derived …
Waste incineration and recycling are releasing large amounts of dioxin, a dangerous carcinogen, says a review of studies in the past three years conducted by AEA Technology of Harwell, Oxfordshire, at the behest of the Environment Agency, UK. These alternatives are deemed by many as an important way to conserve …
The National Institute of Materials and Chemical Research has developed a highly efficient gas sepration membrane that functions like a sieve for gas molecules of different sizes, such as carbon dioxide and nitrogen.
Taisei Corp. has established new technology to clean up large scale areas of polluted underground water. The general contractor hopes to put the new technology to practical use to prevent an increase in water contaimination by factories. The new technology sets up a "purifying wall" consisting of reactive materials and …
Indian scientists have developed a novel method of decomtaminating effluents from the the pulp and paper industry using chemical wastes from the same factory. The new method, devised by the Department of Chemisty, Guwahati University, Assam, exploits chemical wastes like hypo-sludge and coagulants like bamboo dust carbon (BDC) , prepared …
Human fossil remains of early Stone Age, discovered by the Anthropological Survey of India in the central Narmada basin,has led to a debate on the theory of evolution in south Asia.
The ubiquitous plastic carrier bag may no longer be such an eyesore-choking drains or lowering the water table. A fully biodegradable plastic, developed indegenously, is all set to hit the market this year. Obtained by combining starch and low-density polyetheyelene (LDPE) , the plastic is found to have "adequate mechanical …
With worsening urban air pollution, experts fear that people living in the megacities may soon have to wear gas masks and filters just to breathe. That's when a nutty idea that is clean and cheap may come to their rescue. According to a new procerss patent granted to American agricultural …
The National Institute for Resources and Environment in Japan said it has developed a simple analysis technology that can be used to continuously measure for toxic, volatile organic chlorinated compounds such as trichloroethylene. Not only can the system discriminate between compounds, but it can also track chages in the concentration …
A practical low-cost technology for detoxifying contaminated water and soil has been developed by researchers from Yokohama National University and the Kanagawa Environmental Research Center in Japan. Their technique uses the optical catalyst titanium oxide to decompose organic chlorinated compounds with 100% efficiency, inexpensively and without generating secondary pollutants.
disruption of marine ecology is being blamed for cases of food poisoning leading to paralysis in a large number of people in the southern state of Kerala during September and October. More than 1,000 people were hospitalised with symptoms of food poisoning. Many people collapsed, felt dizzy, and their nervous …
The findings of a study team, comprising zoologists led by Takeo Kawamachi of Osaka City University and commissioned by Japan's Mammalogical Society, say that half of Japan's mammals face the threat of extinction. The results also say that the government's official assessment has underestimated the country's wildlife crisis. The team …
the predator management programme in the managed forests of the us state of Alaska has aroused an age-old ecological debate. A report prepared by the National Research Council, the principal operating arm of the us National Academies of Sciences and Engineering, says that wildlife managers in Alaska may be able …
A University of Tokyo research group said it has developed an efficient method using finely powdered quicklime to remove sulphur compounds from the gas emissions at coal-burning power plants. Compared to the conventional desulfurization technique, which involves passing the gas through water mixed with limestone, the new method achieves the …
The Bombay Textile Research Association and the Petroleum Conservation Research Association have developed a Vapour Recovery System for kerosene which is normally expelled in the atmosphere by textile industries.
DRDO scientists have developed a water purifying instrument which is capable of purify 2000 litres of water per hour. This instrument is capable of purifying the water which gets polluted by the radioactivity after the atomic attack.
The photochemical smog that forms on a sunny day over car-infested cities bears little resemblance to the soot-laden 'pe-souper' fogs of coal-burning Victorian London. But in a report in nature (September 10), Dr. Markus Ammann and colleagues from the Paul Scherrer Institute, Villigen and the University of Bern in Switzerland …
Russian scientists have found a method of regenerating ozone in the Earth's atmosphere using laser radiation. The method involves exposing the atmosphere to laser radiation of a certain wavelength which is actively absorbed by oxygen molecules which then transform into a state of hyperactivity.Later on under the impact of sunlight …
volcanoes eject large amounts of sulphur into the atmosphere when they erupt, and actually contribute significantly to global cooling. The eruption of Mount Pinatubo, Philippines, on June 15, 1991, discharged huge amounts of ash and other debris into the atmosphere, creating the largest stratospheric cloud of sulphur dioxide ( so …
Misguided introduction of the Indian mongoose by farmers in Jamaica over 50 years ago had resulted in decimation of the reptile population in the island. The mongoose had been introduced in an attempt to control the rat population. But they failed to take into account the animals' habits. The mongoose …
