No Mers from pasteurised camel products: Experts
No Mers from pasteurised camel products: Experts Amanda Fisher (amanda@khaleejtimes.com) / 14 August 2013 With a link established between camels and the deadly coronavirus that has killed 46 people, scientists are at pains to reassure the public camel products are still fit for consumption. In the wake of news that scientists in the UAE, the Netherlands and Germany have discovered anti-bodies from the Middle Eastern Respiratory Syndrome — a relative of Sars — in dromedary camels, fears have been mounting amongst both the public and camel owners about the safety of consuming camel products. Since last year there have been 94 confirmed Mers cases, including five in the UAE, which led to the death of an elderly Emirati man from Abu Dhabi — who already had cancer. Dubai-based Central Veterinary Research Laboratory (CVRL) virologist Renate Wernery, who is working on the international research alongside husband and CVRL scientific director Dr Ulli Wernery, said local camel owners had “expressed concern”. However, the husband and wife team have assured all camel products in the country are completely safe — as long as they are pasteurised. “The camel milk and camel milk products that go to the public are pasteurised, and any virus, including the coronavirus dies off — that is a scientific fact — at 56 degrees Celsius. Pasteurisation happens at a much higher temperature.” Pasteurisation occurs between temperatures of about 63 and 75 degrees Celsius. “The public is concerned now that there is an insecurity from consuming products from the camel, which is absolutely not valid. Everything is safe, especially from the market here.” Dr Ulli Wernery said the presence of Mers antibodies in camels could even be a good thing. “People have confused the antibodies which have been found in the camels with the virus but the virus has not been found in camels. Camels developed antibodies against the virus which protect them from the disease, it’s very harmless, it’s good even — (the camels are) protected from the virus.” It was not clear how or when camels had come into contact with the Mers coronavirus, though one theory suggested the link had come from bats “but maybe it comes from rats or mice in the desert, who knows?”. “(Camels) have connected to the virus some point during their lives, but we don’t know when — it could be 10 years ago,” Dr Ulli Wernery said. And if camel populations were really hosting the virus, the Wernerys should know about it — the avid camel milk fans, who drink the milk daily, work closely with a large population of camels. “I have done more than 1,000 (post mortems) on camels and I’m still very fit. I really come into contact very closely and nothing has happened…I’m not worried at all,” Dr Ulli Wernery said. Renate Wernery said camels had “very aggressive, robust” immune systems, which meant they had antibodies to many diseases — sometimes diseases that had never even manifested. However, talk of where the highly contagious virus started and how it had transmitted to humans was “speculation”. “Nobody knows yet where the source of the virus is, but CVRL is of course interested to solve the whole mystery. We will keep working with international researchers, this is our duty as scientists…we have to find out more about it, but nobody should be afraid at the moment to use camel products.” While some of the people who had contracted Mers had had direct contact with camels, including the Emirati man who died after treating a sick camel, most had pre-existing diseases such as diabetes or cancer. The scientists’ have been backed up by the World Health Organisation, which states on its website most human cases did not have a history of direct contact with camels. “It is unlikely that transmission of the Mers-CoV to people occurs through direct exposure to an infected camel, as very few of the cases have reported a camel exposure.” The WHO stated the route of transmission to humans may be indirect, and recommended people avoid contact with “obviously sick” animals, including camels. “Animal products processed appropriately through cooking or pasteurisation are safe for consumption but should also be handled with care.” His Highness Shaikh Mohammed bin Rashid Al Maktoum, Vice-President and Prime Minister of the UAE and Ruler of Dubai, sponsors all work conducted at CVRL.

Building A New Biofuels Industry
Volume 91 Issue 4 | pp. 20-22 Issue Date: January 28, 2013 Building A New Biofuels Industry After years of delays, the first commercial-scale cellulosic fuel facilities are nearing completion By Melody M. Bomgardner Poet-DSM Advanced Biofuels, KiOR , Beta Renewables , and other firms will validate the technologies, confirm financial returns, and draw additional investment. “If you look at these projects, they show that the industry has come a long way,” says Jim Lane, editor and publisher of Biofuels Digest, an online newsletter covering biofuels. He’s not dwelling on past proclamations. “Sure, we could rerun the tape, but there were many things the companies were not in control of. The good news is they are here.” Cellulosic fuels are intended to be an alternative to petroleum-derived fuels and first-generation biofuels made from corn. The barriers to commercial success have been technology, the ability to scale up, and project financing. By 2008, after five years of laboratory work and pilot successes, several biofuels firms thought their technology was ready to go. But when the recession hit, the capital markets dried up, and the industry spun its wheels. “What we view as the dominant factor behind the slow scale-up is constrained availability of capital,” asserts Pavel Molchanov, research analyst for investment bank Raymond James in a note to investors. “Second-generation commercialization is a highly capital-intensive undertaking—much more so than the prior decade’s build-out of corn ethanol plants.” [+]Enlarge Molchanov says facilities based on technology that uses dense but cheap cellulosic feedstock such as timberland wastes or municipal waste come with the highest price tag. KiOR’s $222 million plant will make 13 million gal per year of its biocrude from forestry residuals. That works out to a capital cost of $17 per gal. Cellulosic ethanol plants that run on corn-farming leftovers, like the facility run by a joint venture of Poet and DSM, will carry capital costs of $10 per gal and up. In contrast, modern ethanol plants that run on corn sugar are built for close to $2.00 per gal. However, corn ethanol producers face high and volatile feedstock costs, and that is why cellulosic fuel producers are confident that their more expensive plants will still be profitable. “We wouldn’t be making the investment if we didn’t think it was an opportunity to generate good business for the joint venture,” says Wade Robey, a member of the Poet-DSM board. Robey says he is “very bullish” about Project Liberty, the venture’s first facility, located in Iowa, as well as plans to expand to other Poet locations that currently make corn ethanol. Expanding may bring new hardships, however. For companies that use agricultural waste, Lane points out, each new facility will be increasingly difficult to site because of what he calls the “biomass radius problem.” A typical facility consumes 285,000 tons of biomass per year, requiring a reach of 40 to 50 miles of cropland. The next plant must find its own untouched radius of land. All the more reason why it’s good to be first. Access to capital is the key reason why Beta Renewables’ plant, in Crescentino, Italy, will likely be the first to start commercial production. Beta’s parent company, Mossi & Ghisolfi, the world’s second-largest producer of polyester resin for bottles, has heavily invested in cellulosic ethanol research and development. Beta’s sister company, Chemtex, M&G’s engineering division, built the plant. “It was a gutsy decision to invest hundreds of millions of M&G’s own money to be first—to put their money where their mouth is and slash through the chicken-and-egg problem,” says Kevin Gray, vice president of biobased chemicals for Chemtex. Although the Italian plant will be built without any government assistance, Beta’s first U.S. facility, in Sampson County, N.C., will benefit from a $99 million loan guarantee and a $4 million biomass crop assistance grant from the U.S. Department of Agriculture. Other projects have been similarly blessed. Abengoa can take advantage of a $133 million loan guarantee from the Department of Energy for its cellulosic ethanol plant near Hugoton, Kan. Ineos Bio has been awarded a $50 million DOE grant, a $75 million USDA loan guarantee, and a $2.5 million grant from the state of Florida. The more important government assistance, however, comes from the Environmental Protection Agency’s RFS, which requires fuel blenders to use cellulosic fuels in their product or pay a fine. By guaranteeing that all production will be bought, RFS drives investment in new capacity. Petroleum and fuel blenders are pressuring EPA to waive the requirement or even do away with it. “Congress foresaw that the aggressive renewable fuel standards might be unattainable and established several waiver provisions in the Clean Air Act, including for inadequate domestic supply,” Charles T. Drevna, president of the American Fuel & Petrochemical Manufacturers, recently said. “If zero production doesn’t meet the definition of inadequate, then it is time for Congress to reexamine the entire RFS and its failure to produce their desired results.” So far, challenges to RFS have hit a brick wall at EPA. The agency has not yet set the amount of cellulosic biofuel that blenders must use in 2013, but the Energy Information Administration has told EPA that it expects 9.6 million gal to be produced this year. In 2014–15, capacity will expand again as the first facilities from BlueFire Renewables, DuPont, Fulcrum BioEnergy, LanzaTech, Mascoma, and ZeaChem come on-line. Not every company is likely to succeed, but the scattershot approach will uncover technologies that work, Lane predicts. “You don’t need more than three if they work,” he says. “If you have a growing technology and you take the corn ethanol boom as an example, there is no reason you can’t build 100 or 200 of these plants a year.” Chemical & Engineering News Continue reading
Nurseries must get nod for evening shift
Nurseries must get nod for evening shift Ahmed Shaaban / 12 August 2013 Nursery schools are not usually permitted to receive small children in the evening but a few exceptions have been allowed by the Ministry of Social Affairs. Moza Salem Al Shoomi, Director of the Child Department at the ministry, said some families had approached the ministry requesting nurseries to keep their young children till late in the evening. “All these applications are normally rejected, but some specific requests are allowed.” A nursery could never substitute a child’s own family who needed to take the responsibility and bring him or her up properly. “A child may not be kept away from his/her mother for over eight hours a day.” Al Shoomi said some requests for the same had been allowed, but only till 6pm, after being convinced of certain situations like the mother having to work late into the evening in a private institution. “However, the ministry’s approval is needed in advance, and the charges for the same may never exceed those paid in the morning shift according to the number of requested hours.” According to the set rules, all nurseries are only open from 7am to 2pm. “Of course, those given permission to receive young children in the evening may only be open till maximum 6pm.” “Also, no children above the age limit (five years) can be received in the evening period. “No activity other than the listed ones should be practised during the evening time, and the nursery building may only be used for the purpose it was built for. The nursery management shall be held responsible for all activities.” Al Shoomi warned that the evening permit issued for some nurseries would be revoked in case the management proved to have flouted the set conditions or been warned by the ministry inspectors. “All nurseries must be off on Fridays and Saturdays every week, and no nursery is allowed to take an extra day off,” she said, noting that it was very critical for all nurseries to abide by all official holidays and weekends. Meanwhile, the ministry issued a warning letter against a nursery and ordered it to be put under strict surveillance after a child was found to be harmed. “We have received 18 family complaints against nurseries in the first half of the year, and this reflects an increasing awareness among families of the nature of nurseries’ work.” She added that a little child had a hand broken while playing in one of the nurseries operating in the country this year. “Though the incident is normal, it has been one of the most harmful to young children at the nurseries here.” The complaints were mostly about the absence of headmistresses, failure to take due care of children, accepting children above the age limit, operating without a licence, charging of extra fees, expelling children for not paying fees, letting workers in during nursery hours and lack of competent cadre. “While the ministry issued licences for 29 new nurseries from January to June this year, 119 applications for opening new nurseries were rejected for not meeting the conditions.” – ahmedshaaban@khaleejtimes.com Continue reading
