It took the team 13 months of working 24 hours a day to complete the project.Envitech has also been involved in landfill site management in Amman, Jordan, and has recently been acknowledged as a service provider for Shell at the world’s largest gas to liquids plant in Qatar.Closer to home, the company constructed Africa’s first landfill gas-to-electricity project at the La Mercy and Marian Hill landfill sites in Durban, with the latter winning a number of international awards.Today the Marian Hill site supplies about 1MW of electricity to the municipal grid.“This is the first landfill gas-to-electricity project to be developed in terms of the CDM (Clean Development Mechanism) under the Kyoto Protocol in South Africa and Africa,” said Jewaskiewitz.Electricity generation is not the only spinoff of this venture, as it’s also helping destruct methane which makes up 40% to 50% of landfill gas. As a greenhouse gas, methane is 21 times more potent than carbon dioxide.The World Bank has signed an agreement with the eThekwini Metro Municipality, under which Durban falls, to buy the carbon credits generated through this eradication of methane.Envitech has also been involved with gas-to-electricity conversion at the Bisasar Road site in Durban, which one of the largest landfills in the southern hemisphere.“We were responsible for the installation and operation of the first four 1MW units at the site. It now has six 1MW units and one 0.5MW unit running there continuously.”Jewaskiewitz’s company also processes sewerage; shredded tyres; industrial, commercial and medical waste; as well as glass, paper and tin cans. The various by-products of this are either compost, electricity or water for re-use and irrigation.In addition, Envitech is working on a landfill gas extraction project for the Ekurhuleni Metro Municipality, east of Johannesburg, and the first waste-to-electricity venture in South Africa for the Drakenstein Municipality in the Western Cape.Sustainability through food securityKwaZulu-Natal’s Mpilende Foods also helps generate energy – albeit of a different kind.Meaning longevity in isiZulu, Mpilende is a 100% black owned and managed company which produces fortified food products for South African government schools and feeding schemes, humanitarian aid organisations, as well as wholesale and retail consumption.Its range comprises instant foods, food supplements, health and energy drinks, vitamin mixes and baby formula. Most of these are soya-based.The way the company sources its raw materials helps it achieve its core values of sustainability and empowerment.“We must be inclusive in how we procure our food for processing,” said Mpilende’s chief financial officer Thami Masuku.“This must involve sensitivity to the environment and sensitivity to parts of South Africa which have not always been aligned to the mainstream economy.“Our socio-economic responsibility is to work with communities in the rural areas, which are ideally placed to be our key suppliers. We enable these societies to participate in a semi-commercial activity that produces our raw materials which we can then process into Mpilende foods.”According to Masuku, this approach combined with the nutritional benefits of Mpilende products, helps support “the web of life”.The company also exports its products to other African states where war and poverty has led to wide-spread malnutrition.All foods produced by Mpilende are tested by the South African Bureau of Standards and endorsed by the Food and Drug Administration Board, the Nutrition Society of South Africa and the country’s Food Safety Corporation – among a host of other internationally recognised statutory bodies.Such global backing has won the company and its products a range of accolades over the years, including Europe’s International Award for Quality in 2010 and the Africa Growth Institute’s SMME Award for 2009 in the category “best new business”.

Salman Khan, Katrina Kaif in BharatYouTube ScreenshotSalman Khan is extremely confident not just about the content of his upcoming movie Bharat, but also on the work done by his co-actress Katrina Kaif in it. So much so that the superstar feels Katrina will bag a national award for her performance in the film.At a recent song launch event of Bharat, Salman could not stop praising his co-actress’ work in the film. He is so impressed by her that he went on to say that Katrina will definitely get national award for it.”Katrina will get national award for this film,” he said at the event. When the reporter and Katrina laughed on it, he added,” Seriously. You will see. She is so good in the film, and she has worked so hard in it. So, it is certain that if anyone would get national award, it will be Katrina only”.At the same event, Salman also praised Sunil Grover saying that he is one of the most talented actors he ever came across. Apart from Salman, Katrina and Sunil, the film also features Disha Patani in a key role.Directed by Ali Abbas Zafar, Bharat is one of the most awaited films of this year like most other movies of Salman. The superstar will be seen in multiple avatars in the flick, including that of a 70-year-old man. It is slated to be released on June 5.

(PhysOrg.com) — Detecting hidden explosives is a difficult task but now researchers in the UK have developed a completely new way of detecting them, with a laser sensor capable of detecting molecules of explosives at concentrations of 10 parts per billion (ppb) or less. © 2010 PhysOrg.com New method for detecting explosives More information: Ying Yang et al., Sensitive Explosive Vapor Detection with Polyfluorene Lasers, Advanced Functional Materials, Published Online: 25 May 2010. DOI:10.1002/adfm.200901904 Explore further The laser sensor, developed by physicists from the University of St Andrews in Fife, Scotland, relies on the fact that when a type of plastic called polyfluorene is “pumped” with photons of light from a light source it emits laser light. When molecules of the vapors emitted by explosives such as TNT are present, they interfere with the laser light, switching off the emission, and the interference can be measured.One of the scientists, Dr. Graham Turnbull, explained that there is a dilute, weak cloud of vapors of nitroaromatic-based explosive molecules above an explosive device. He said the laser could be thought of as an “artificial nose for a robot dog.”In the study a plastic laser was exposed to 1,4-dinitribenzene (DNB) vapors at 9.8 ppb concentration. The light emitted by the laser decreased rapidly, allowing for detection within seconds of the exposure. After 4-5 minutes the response had slowed and then flattened off, which the researchers suggest is due to the vapor molecules interacting with the surface of the polyfluorene. The laser took three and a half hours to recover in air, but only three minutes if nitrogen gas was flushed through it and 20 seconds if purged under a vacuum.The plastic polyfluorene is a cheap material, which is an obvious advantage for a device designed to detect explosives. Dr. Turnbull said that while similar techniques using organic semiconductor lasers had been looked at before, this is the first time scientists have used a polyfluorene laser, and its use enables much lower concentrations of vapors to be detected. Organic semiconductor lasers detect explosive vapors because of a chemical interaction between the vapor and the semiconductor in which electrons are transferred from the semiconductor to the electron-deficient vapor molecules. It is this transfer of electrons that reduces the light emitted by the laser. The same electron-transfer effect occurs with the new polyfluorene laser.The drawback with the laser sensors is that the explosives must be in the very near vicinity, which limits its use for humans, but they could prove extremely useful for applications such as roadside bomb detection in Iraq and Afghanistan, for security checkpoints, luggage screening in airports, and for bomb disposal robots generally. The system could also be used in conjunction with remotely controlled robots for detecting land mines, which are still a danger to people in areas such as Southeast Asia.The findings were published in the journal Advanced Functional Materials.
