Nigerian project wins top award

first_imgCows to Kilowatts takes abattoir waste and converts it into a low-cost renewable energy source. (Image: stock.xchng) An innovative Nigerian project that processes abattoir water and converts the collected organic waste into fertiliser and methane, has won the 2009 Intel Environment prize at the annual Tech Awards in the US.The Tech Awards, held this year in San Jose, California, in November, honoured creativity and inventiveness across a range of fields, including the environment, education, science, health and more.The project, titled Cows to Kilowatts, was founded by civil engineer Dr Joseph Adelgan. In developing countries especially, abattoir waste is a major source of water pollution and greenhouse gas production. Through the processing of organic waste, the project helps mitigate one of the biggest threats to the future of the planet, as well as promote the use and benefits of renewable energy.Adelgan is the founder of the Global Network for Environment and Economic Development Research (Gneeder), an NGO that that works in poor urban communities to improve quality of life, reduce air pollution and create cheap sources of domestic energy.The organisation is currently working on another power-generating project for impoverished West Africans, using cassava factory waste.Projects are based in Nigeria and Ghana at the moment, but there are plans to roll them out in other sub-Saharan countries.Keeping water cleanIn Nigeria regulation of abattoir waste is lax, and there are few facilities for water treatment. In Ibadan, the country’s second biggest city, waste from the Bodija Municipal Abattoir used to run out into open drains. These are connected to surface water sources, which resulted in severe contamination of groundwater with pathogens such as salmonella, Escherichia coli, and the deadly Rift Valley fever virus.The waste water from this abattoir has an extremely high biochemical oxygen demand, which is an indicator of organic pollution. Communities living in the area had no choice but to use the contaminated water, so the situation was desperate.“People were drinking from shallow wells,” said Adelgan in an interview, “and people in the neighbourhood were getting sick. They didn’t understand why they were getting sick.”Cows to Kilowatts started off as a collaborative project between Gneeder, the Centre for Youth, Family and the Law, and the Sustainable Ibadan project. The initial goal was merely to treat the abattoir waste in an effluent plant, rendering it less harmful to communities and the environment and preventing groundwater pollution.However, the team soon came across a related problem – the decomposing organic waste that was releasing carbon dioxide and methane into the atmosphere. Both are greenhouse gases, but methane is 23 times more lethal in bringing about climate change than carbon dioxide.A new strategy using biogas technology was introduced. Applicable on both large and small scales, the process uses reactors to digest organic waste and convert it into low-cost energy.The three founding organisations joined up with scientists at the Biogas Technology Research Centre at Thailand’s King Mongkut University of Technology Thonburi, and with funding from the UN Development Programme in Nigeria, they designed and built a pilot biogas plant in Ibadan. This uses an anaerobic fixed film digester to break down the waste. The resulting sludge is turned into high-quality organic fertiliser, and methane and carbon dioxide are collected before they can dissipate into the atmosphere and cause harm.The plant supplies around 5 400 cylinders of biogas per month, which is used for cooking, electricity generation, and to power vehicles – at just 25% of the cost of liquefied natural gas. Furthermore, the organic fertiliser is sold to farmers at a fraction of the cost of chemical fertiliser.Poor families often have to rely on kerosene, paraffin and wood for heating, cooking and light, which pollute the air in the home. By using biogas they not only improve their living conditions, but also help curb deforestation, as the demand for wood drops.Honouring innovationEstablished in 2001, the Tech Awards came about as a result of the State of the Future report, a publication of the Millennium Project of the American Council of the United Nations University. The report stated that acknowledgement of innovation through awards is a valuable tool for stimulating scientific and technological breakthroughs to improve people’s quality of life.The Tech Awards programme pays tribute to technology that enables people to live a better life. It honours 15 enterprising projects in five categories: health, education, equality, the environment, and economic development. There are three winners in each category, and the top five laureates walk away with US$50 000 (R378 717) each.Laureates are then inducted into the Tech Awards Network, which provides opportunities for learning, networking and collaboration.last_img read more

South Africa announces 2015 Rugby World Cup squad

first_imgIn naming his chosen few, Springbok coach Heyneke Meyer said the 31-member squad that would represent South Africa in the Rugby World Cup would carry the country’s hopes on their shoulders. It would be a tough tournament, he cautioned. Jean de Villiers will captain the team.The South African Rugby Union announces the 31-member team that will represent the country in the Rugby World Cup, on 28 August 2015. The championship takes place in England from 18 September to 31 October. (Image: The Yellow Cap)Jean de Villiers would captain the South African rugby team, the Springboks, at the Rugby World Cup in England starting on 18 September, the South African Rugby Union (Saru) announced on 28 August.Victor Matfield was named as vice-captain, and Schalk Burger would provide captaincy back-up for the 31-man squad.“We’re going to England with the hopes of a nation on our shoulders and we would really like to make our country proud, but we’re under no illusions about how tough it will be,” said coach Heyneke Meyer.It will be the first Rugby World Cup for 16 of the players, while six players who took part in 2011 were selected to represent South Africa again. The average age of the selected players is a little over 26 and their combined number of caps is 1 297.The squadWillem AlbertsSchalk BritsSchalk BurgerDamian de AllendeLood de JagerJean de Villiers (captain)Bismarck du PlessisJannie du PlessisFourie du PreezPieter-Steph du ToitEben EtzebethBryan HabanaZane KirchnerSiya KolisiJesse KrielPatrick LambieWillie le RouxFrancois LouwFrans MalherbeVictor Matfield (vice-captain)Tendai MtawariraLwazi MvovoTrevor NyakaneCoenie OosthuizenRudy PaigeRuan PienaarJP PietersenHandre PollardMorne SteynAdriaan StraussDuane VermeulenDifficult selectionMeyer said it was very tough to select the final squad from the wider training group that had been together for the last two months.“Every single player in our wider group worked incredibly hard and to cut the squad to 31 was probably the most difficult selection I’ve faced in my coaching career,” he said. “In the end, the selectors decided the 31 players named were the best we have at the moment but that is not to say any of the others won’t have a role to play, with injuries a reality in our game.”In the selection, consideration was also given to utility players – those who could move between positions.“I think the squad has a great balance between youth and experience while keeping together the core of the team that did the country proud in the last few years,” said Meyer. “We also have a number of players who know what it takes to win a World Cup and their knowledge will be very valuable.”Gratitude and supportA few players took to social media to show their pride.“Honoured and privileged to be selected to represent my country at #RWC2015,” tweeted Pietersen. “So grateful and thankful.”Steyn echoed his sentiments: “Such an honour to be part of this again! #WorldCup2015 #SA.”Take to the field on the backs of the Boks.

But along with New Zealand and Australia, the Boks have won the most World Cup trophies at two each. New Zealand won in 1987 and 2007; Australia won in 1991 and 1999; and South Africa won in 1995 and 2007.In other records, the least points conceded in a tournament were 35 by South Africa in 2011, while Habana ties with New Zealand legend Jonah Lomu in scoring the most tries in one competition. Lomu scored eight tries in 1999, and Habana made his record eight in 2007.Source: South African Rugby UnionWould you like to use this article in your publication or on your website?
