Girls turn poo to clean power in Cameroon biogas push

BUEA Cameroon An initiative by youth organisations in Cameroon to turn human waste into biogas is reducing pollution and providing cheap renewable energy to the growing populations of the university towns of Buea and BamendaBioenergyCameroon a nongovernmental organisation run by young people installs equipment that converts waste from septic tanks and pit latrines into biogas which can be used for cooking or heating and can power small generators to run household electrical appliancesThe organisation says its efforts are spurring the use of clean energy in homes and secondary schools where grid electrical power is nonexistent or unreliable and alternative sources of energy such as gas cylinders are expensiveMany have come to discover the cheap energy in their backyard and are not only embracing the technology but are also learning the transformation process said Cedrick Kemajou Bioenergys coordinatorAs it expands the project is bringing local councils and other youth groups on boardWith exponential growth of the university town of Buea we had problems handling human waste That is why we are glad that this waste can be used to produce energy that will help the residents not only fill the energy gap but also tackle human waste and sewage management problems said Patrick Ekema mayor of BueaEkema said that with easier access to energy the council can better tackle other development problems such as providing clean waterGIRLS GO GREENBiogas is produced by connecting a septic tank to a biodigester which breaks down the organic matter producing a natural gas known as biomethaneStudents in schools where the infrastructure is installed are trained in the biogas transformation process and are shown how to build install and maintain the biodigester and generators at the schoolWe give practical training to girls in colleges on how energy is generated from the sun water and human waste said Monique Ntumngia coordinator of Green Girls a Cameroonian NGO that trains young women in technologyWe target female students especially to break barriers and get them into innovative technology Ntumngia explained Green Girls has trained 600 girls in schools in towns such as Bafut Nkwen and Mankon she saidAn additional 3000 households in Buea and Bamenda have received domestic biodigesters through the project and demand is growing fast project organisers sayMany students in Buea and Bamenda say they have long suffered from persistent blackouts on the traditional grid power where energy largely comes from hydropowerWe could not study well during such blackouts that sometimes last for over a week We have been suffering even though we are blessed with a clean energy source in our backyard said Magdalene Lum a student at the University of BueaThe new energy from our human waste will supply us electricity constantly and cheaper Lum saidCOSTS AND BENEFITSAccording to data from the World Bank only 53 percent of Cameroons population of 23 million have access to electricity Bottled cooking gas can be difficult to afford especially for Cameroons poorest A 12kg cylinder of liquefied petroleum gas costs 6000 Central African francs FCFA or nearly 10 according to the Ministry of TradeFamilies benefiting from the cheap biogas say they are using the money they save for other essential items such as schooling and medical careBiogas has spared me the trouble of paying monthly electricity bills and buying bottled gas that is regularly out of stock This has saved me some money to support my childrens education said Mercy Kum a trader in BueaCollege officials are pleased that biogas insulates their budgets from what can be volatile electricity prices Rates fluctuate according to the availability of hydropower which is increasingly vulnerable as climate change brings more droughts and floodsThe biogas we generate provides a constant supply of the energy the school needs unlike the hydroelectricity that regularly goes on and off said Peter Nke principal of Baptist High School BueaHaving a biodigester installed and receiving training to use and maintain it costs 500000700000 FCFA 8001100 a sum paid by the institution or households that request the service A group of homes can use a common biodigester to share the expenseREDUCING DEFORESTATIONTurning waste into biogas may not be new in Cameroon but the youth organisations say producing it from human waste in multiple households and institutions and training students especially girls on the technology is an innovationMost boarding schools in the Northwest and Southwest regions now use biogas for cooking and lighting produced from human waste with trained students to manage the process said NtumngiaSamuel Nguiffo executive secretary of the Center for Environment and Development CED an NGO in Cameroon explained that most communities in urban areas traditionally use charcoal or kerosene stoves for cookingCharcoal production creates a huge demand for wood which has frequently led the government to impose bans on charcoal burning and forest destructionThe use of biogas energy should help preserve the countrys forests Nguiffo saidCED estimates that the biogas project may be reducing greenhouse gases by as much as 60 percent in the vicinity of the projects as well as curbing pollution from open air defecation and pit latrinesCameroon will derive enormous economic health and especially environmental benefits if renewable energy efforts are spread throughout the country he said
