No Comments on Bio-ethanol From Sturdy and Once-Unwanted Indian Plant

By David South, Development Challenges, South-South Solutions

With awareness of global warming at an all-time high – and governments seeking real-world solutions to solve this enormous problem – bioethanol fuel has risen up the agenda as a replacement for conventional fuel sources. At present, most bioethanol fuel is produced from either corn or sugar but a less known plant jatropha could be the real solution. Brazil has been a pioneer in producing bioethanol fuel from sugar, while the United States has focused on its substantial corn crop as a source, and both contribute more than half the world’s supply. Brazil alone made US $5.4 billion from biofuels (ethanol and biodiesel combined) in 2005, while global production is estimated at 48 billion litres (Biofuel Market Worldwide (2007-2010) www.canbiotech.com).

Global prices for crude oil, under pressure from a number of sources, are volatile and far above 1990s levels. This hurts the poorest countries most (Human Development Report 2005). Expensive fuel means the world’s poor are denied affordable access to machinery and appliances that can make life more comfortable. Poorer nations are often more dependent on oil imports than richer countries. As well, most of their industries are energy intensive, and their cars and homes are less energy efficient. This means low-income countries spend twice as much of their national income on imported oil than do developed countries (World Bank). A US $10 per barrel increase in the cost of crude oil shaves half a percentage point from economic growth in the West; in the poorest countries, it is nearly three times higher.

The two common sources of bioethanol fuel – corn and cane sugar – have a major drawback: they are diverting food sources into fuel for vehicles. Already, the massive US diversion of corn into the bioethanol fuel market has sent the price of corn skyrocketing, making this hardy food staple in countries like Mexico more expensive for the poor. Some estimates claim ethanol plants will burn up to half of the United States’ domestic corn supplies within a few years (Foreign Affairs). To fill the fuel tank of a sports utility vehicle (SUV) with pure ethanol requires 450 pounds of corn – enough calories to feed one person for a year.

And this is why many are now advocating a non-edible Indian fruit bush called jatropha as a better solution. It is like a grapefruit, with each fruit containing three plum-sized seeds. Each seed contains 35 percent oil which can be converted into biodiesel. A shrub from the family euphorbiaceae, jatropha’s lifespan is 50 years. It bears fruit several times a year, and each bunch is five to eight fruits. Being unedible, the oil is mostly used for soap and varnishes.

Cultivation of the jatropha was prioritised a year ago by the Indian Railway Minister, Lalu Prasad Yadav. Disused railways lands were to be put aside for growing the crop. Brazil’s biodiesel company, Biomasa, plans to plant two million hectares with jatropha this year, and it is believed jatropha will surpass sugar cane as the principal source for bioethanol in Brazil.

The advantages of jatropha include its hardy nature: it does not require pesticide, manure, or irrigation to grow and it is drought resistant. A single jatropha plant will yield one litre of biodiesel per year for 40 years, and it yields 1,300 kg of seeds per hectare per year. Its advocates hope to see jatropha bushes planted alongside existing crops, with an acre producing 100 litres of fuel per year.

The downsides of cultivating jatropha as a fuel source would need to be overcome. At present, jatropha’s high acidity means its seeds degrade quickly in humid environments (much of the global South) when exposed to air. Steel tanks used for storage require a nitrogen blanket to prevent water absorption. During the processing stage (something called transesterification), the large quantities of glycerine are produced as a byproduct. Demand is low for this byproduct and disposal is a problem. A cake is also produced that has no real value or use. To make it economically worthwhile to grow in India for example, farmers would need to receive four rupees per kg of seed. This would produce a biofuel costing 50 rupees per litre – considered too expensive at present. Jatropha advocates are urging government subsidies to kick-start production and make the price competitive.

In Ghana, smallholder farmers have already rebelled against growing jatropha. They say that since the oil is inedible, and growing the crop leaves them at the mercy of price-setting by the refineries, they do not want to run the risk.

“What may encourage farmers to venture into jatropha,” said Wisdom Yao Adjah-Cudjoe, a cereal farmers’ representative, “would be a guaranteed price arrangement, as is the case with cocoa.”

In Africa, research by the South African Biodiversity Institute has estimated that 50 percent of the landmass of the continent is suitable for jatropha cultivation (a total of 1,080 million hectares). It could be a huge opportunity for African farmers and a big cost saving for poor countries, but if farmers are to be encouraged to grow jatropha, they will need the right price incentives and guarantees.

Successful Fuel-Efficient Cookers Show the Way

No Comments on Successful Fuel-Efficient Cookers Show the Way

By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

A Kenyan entrepreneur has cooked up a fuel-efficient stove and oven that uses less of a precious national resource: wood from trees.

Most African households using fuel-burning stoves either cannot afford clean-burning fuels like natural gas or electric stoves, or do not have access to them. They are stuck having to burn wood or other materials like animal dung – collectively called biomass – on open fires.

As well as using up wood and contributing to deforestation, there is another downside to these stoves. The use of polluting fuel-burning stoves by half the world’s population – including 80 percent of rural households – is a documented contributor to a host of health problems. Poor households not only have to contend with the ill health effects of dirty water and poor sanitation, the fumes from burning dung, wood, coal or crop leftovers lead to the global deaths of more than 1.6 million people a year from breathing toxic indoor air (WHO).

Two solutions in Kenya are helping people to cook more efficiently (meaning less time wasted on gathering material to burn, and less fuel used) and reducing cooking time by using heat more effectively.

Invented by Dr Maxwell Kinyanjui, the Kinyanjui Jiko is a fuel-efficient charcoal oven that comes in small, medium and large industrial sizes. Made entirely in Kenya, the ovens are custom designed for a variety of environments, from domestic household use and on-the-go safari models to high-capacity models for micro-enterprises and large institutions. Cooks can use the ovens to bake, toast, steam or boil. And they are 40 percent cheaper than cooking with electricity and between 15 and 20 percent cheaper than gas.

Kinyanjui’s Musaki Enterprises Ltd. (www.reskqu.blogspot.com/2009/01/arboretum-project.html) has developed a reputation for pioneering work in developing fuel-efficient stoves and ovens. Its most popular success to date has been the Kenya Ceramic Jiko (jiko is Swahili for cooker), or KCJ, a cheap, simple and effective stove. The company was set up in 1992, but has been involved in international aid-funded research and development efforts since the 1980s.

“My dad was on a very good team of highly motivated individuals in the early 80s who developed the stove through pragmatism, logic and good old-fashioned ingenuity,” said his son, Teddy Kinyanjui. “He then set up the independent Musaki Enterprises.”

The KCJ uses a ceramic liner placed inside a metal container. The metal is usually recycled, often taken from 55 gallon steel drums. The ceramic liner stops the heat energy from simply escaping into the environment and helps to focus the heat on cooking. Simply adding the ceramic liner reduces the stove’s fuel consumption by between 25 and 40 percent. The charcoal or wood sits in the ceramic basin and the burnt ash falls through holes in the bottom of the liner.

The stove design was a result of international and Kenyan cooperation, and has become popular in many African countries, including Uganda, Rwanda, Ethiopia, Malawi, Niger, Senegal and Sudan. It is used in 50 percent of urban homes in Kenya and 16 percent of rural homes.

Musaki Enterprises say the KCJ stoves on average save between 1 and 1.5 tons of CO2 per stove per year compared to other models. In supermarkets, the KCJs retail for around US $5 and the Kinyanjui Jiko ovens start at around US $100.

The deployment of the KCJ stoves has helped in slowing the deforestation of the country, but has not been able to bring it to a halt because of population growth and poor re-forestation efforts, says Teddy Kinyanjui.

“The lack of forward planning in tree planting is making firewood and charcoal harder and harder to obtain,” he said. “Fossil fuels are unavailable or unaffordable. Tree planting must begin now on a huge scale for people to continue cooking.”

Teddy won’t reveal how profitable the KCJ stoves have been, but says, “I wouldn’t have gone to school if they didn’t sell well.”

“Well, more and more people keep buying the damn things as fast as we can make them, so I think our customers like them,” he said. “They really all seem to like that the stoves cook really well for really cheap and are very high quality.”

Innovation: Cairo’s Green Technology Pioneers

No Comments on Innovation: Cairo’s Green Technology Pioneers

By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

One thing is ubiquitous to every country, community and society: garbage. It’s a social and environmental problem, but far from being mere waste, rubbish has its uses. This by-product of the goods and foods consumed can also be a source of fuel. As such it has many advantages, including providing free fuel to cash-strapped households, independence from unreliable municipal services and a way to dispose of waste.

An enterprising Egyptian man is showing his community how it is possible to lower the cost of gas and hot water while also avoiding the service disruptions common with municipal utilities. In the process, he is pioneering a local green innovation model that can be replicated elsewhere.

Biogas (http://en.wikipedia.org/wiki/Biogas) generators — which can transform organic household waste into fuel — have been very successful in India and China. It is estimated there are 20 million small-scale urban biogas digesters in China and 2 million in India.

Hanna Fathy’s roof in the Manshiyet Nasser neighbourhood, home to the Coptic Christian Zabaleen community of Cairo – the city’s traditional garbage collectors and recyclers – is now a utility system, providing biogas and hot water.

The area is made of narrow streets and makeshift houses. Residents live cheek-by-jowl in a neighbourhood that is home to tens of thousands of people.

The community was badly hit when the 300,000 pigs the Christian residents have kept for the past 30 years to eat Cairo’s vegetative waste — an effective garbage-disposal system — were slaughtered under government orders to prevent the spread of swine flu (H1N1) (http://en.wikipedia.org/wiki/Swine_influenza).

One woman told U.S. National Public Radio about the hard life in the neighbourhood: “I’m working all the time. My hands get dirty, there’s no water. The price of food is too high. The gas has gone up to seven pounds (US $1.28) a bottle, so it’s expensive to heat.

“Everything is so expensive, and I have to live like this?” she said.

Fathy plops kitchen scraps, stale tea and tap water into a jug which he pours into a homemade biogas maker on the roof of his house. The stew of waste mixes with water and a small quantity of animal manure used to start the process, and overnight makes biogas, which is then used for cooking. The digester is able to provide an hour’s worth of cooking gas a day in winter months, and two hours in the summer, from around two kilograms of waste. The remaining waste by product becomes liquid organic fertilizer for the garden.

Fathy has been developing the biogas digester with the NGO Solar Cities (http://solarcities.blogspot.com), which provides designs, technical advice and support to Cairo citizens keen to embrace green technologies.

What is interesting is not only the technology but how that technology is being developed. The approach is to innovate and adapt the technology to local resources and skills. This increases the chances of take-up and buy-in.

The designs for the digesters and heaters have evolved through experimentation, brainstorming and availability of local materials.

Each biogas system costs about US $150 for materials, a cost that is being picked up right now by donations. Solar Cities believes there are only eight biogas digesters in Egypt so far, most built in 2009.

Solar Cities’ founder, Thomas Culhane, points out many urban dwellers do not believe they can generate biogas and associate it with rural systems that use animal manure. But the abundance of urban kitchen waste is in fact an excellent source material for biogas.

Culhane believes the biogas digesters are an excellent solution to two problems: the vast quantities of garbage piling up in Cairo, which has had its traditional disposal system disrupted by the slaughter of the pigs, and the city’s emissions of greenhouse gases that contribute to climate change.

Fathy has one goal: to be completely self-sufficient. He has been also prototyping a solar heater on his roof as well as the biogas digester. The solar water heater makes use of items that can be easily found: it recycles black garbage bags, has an aluminium frame and a glass cover. The whole thing rests on a Styrofoam block and uses copper tubes. The water is stored in a bright blue barrel.

Biogas, solar power and other forms of green energy face many obstacles if it is to expand further in Egypt. The average cost of each unit will need to come down to match the income of the users and compete with the government-subsidized energy sector.

Fathy has also found neighbours are skeptical and can’t believe biogas can be made this way.

Another man, Hussain Soliman, had both a solar water heater and biogas digester on the roof of his apartment building before the crumbling building collapsed.

The complete solar water heating system designed by Solar Cities can be assembled for under US $500. It uses two 200-litre recycled industrial shampoo barrels for the holding tank and back-up water supply. The solar panels need to be kept clean from dust every week, but other than that, Culhane insists the heaters require little maintenance.

Now in temporary government housing, Soliman is still enthusiastic about the technology and is re-building a solar heater and biogas digester for his new home.

“I’m planning to collect the organic waste from restaurants in the neighborhood to increase my gas output,” he told IPS News. “I’ll give the restaurants plastic bags and they can separate out the organics, and I’ll collect the bags at the end of each day.”

Egyptian Youth Turns Plastic Waste into Fuel

No Comments on Egyptian Youth Turns Plastic Waste into Fuel

By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

The challenge of finding alternate fuel sources is capturing the imagination of innovators across the global South. As the world’s population increases – it recently reached 7 billion (UN) – and the number of people seeking a better life grows in turn, the energy demands on the planet are pushing up competition for existing conventional fuel sources.

The modern lifestyle that many aspire to requires energy, whether it’s using electronic products which consume large quantities of electricity, driving personal vehicles or living in homes that are artificially heated and cooled.

This energy hunger has opened up a whole new market demand that needs to be met. The scale of this market is enormous, but the solutions are ultimately limited only by people’s imaginations. An award-winning Egyptian teenage scientist is capturing attention for the imaginative solution of turning waste plastic into biofuel, sparking interest in the creation of a whole new source of wealth for her country.

Sixteen-year-old Azza Abdel Hamid Faiad (http://tinyurl.com/dysemjg) has found a new way to take waste plastic and break it down into fuel. She has discovered aluminosilicate minerals (http://en.wikipedia.org/wiki/Aluminosilicate) – which contain aluminium, silicon and oxygen and are found in clays – can break down the polymers that make up plastic (http://en.wikipedia.org/wiki/Polymer) to produce the gases methane, propane and ethane, all of which can be turned into ethanol (http://en.wikipedia.org/wiki/Ethanol), which is useful as a biofuel.

According to Inhabitat (inhabitat.com), a website dedicated to “green design, innovation, and the future of clean technology,” her solution could turn the country’s annual consumption of 1 million tonnes of plastic into a year’s supply of biofuel worth US $78 million.

Clever innovators are sitting on a goldmine if they can come up with renewable energy solutions. The U.S. Army alone is looking to spend US $7 billion on renewable energy sources and is accepting bids from the private sector to meet its needs (http://www.forbes.com/sites/toddwoody/2012/08/08/u-s-army-opens-bids-to-buy-7-billionin-renewable-energy/). The army is looking to sign contracts stretching up to 30 years for buying electricity generated by solar, wind, geothermal and biomass projects.

The options are numerous for renewable energy – from solar power to wind power to algae as a source of biofuels (http://en.wikipedia.org/wiki/Biofuel). The challenge is to find a fuel source that is plentiful, renewable, and crucially, doesn’t harm other needs.

Using biofuel as a replacement for conventional petroleum-based fuels like gasoline and diesel appears to be an attractive solution, but it can lead to other problems. Some people are using used cooking oils to convert into biodiesels, but sometimes there is not enough used cooking oil to meet demand. In short, a constant supply source is required to meet ever-increasing energy demand.

A famous example of where the use of renewable plant-based fuel sources can go wrong is the case of corn. The widespread use of corn as a source for biofuels – rather than for animal feed or human food – has led to accusations this is contributing to the global food crisis. The current drought in the United States is damaging corn crops and only making this problem more acute. The U.S. is the world’s largest producer of corn (US Department of Agriculture) and much of it is used as livestock feed around the world.

Faiad’s solution is appealing because the fuel does not come from biomass – derived from plant matter – but turns waste plastic into the raw material for biofuel.

Plastic waste is a common byproduct of modern life. Plastic is used extensively in packaging, bottles, bags and electronic products. It fills up landfill sites and is a blight on the landscape in many countries. It is also a product made from petrochemicals (http://en.wikipedia.org/wiki/Plastic), the very source of conventional fuel used by most of the world’s vehicles.

Breaking down waste plastic from bottles, packaging and other products into what is called ‘biofuel feedstock’ – the substance necessary to start the creation of biofuel – requires a means to turn the plastic into fuel.

According to Green Prophet (greenprophet.com), Faiad believes her technological breakthrough “can provide an economically efficient method for production of hydrocarbon fuel namely: cracked naphtha (http://en.wikipedia.org/wiki/Petroleum_naphtha) of about 40,000 tons per year and hydrocarbon gases of about 138,000 tons per year equivalent to US $78 million.”

This could be a big economic boost to Egypt’s economy, simultaneously reducing dependence on petroleum-based fuels and creating a new source of income. Egypt’s economy has been hit hard since the start of the Arab Spring (http://en.wikipedia.org/wiki/Arab_Spring). The number of tourists fell 33 per cent in 2011 and revenue dropped by US $3.7 billion from 2010 (Egyptian Tourism Minister). In 2009 about 12.5 million tourists visited Egypt, bringing revenue of US $10.8 billion. The tourism sector is one of the country’s top sources of foreign revenue, accounting for more than 11 per cent of GDP, and offers jobs in a country beset by high unemployment – for Egypt, tourism makes up 11 per cent of its GDP (gross domestic product) (Reuters).

Faiad’s innovation has not gone unnoticed. She received the European Fusion Development Agreement award (http://www.efda.org/) at the 2011 23rd European Union Contest for Young Scientists (http://ec.europa.eu/research/youngscientists/index_en.cfm). She is also receiving interest from the Egyptian Petroleum Research Institute (http://www.epri.sci.eg/), according to Inhabitat.

Ambitious Faiad is also seeking to take ownership of her innovation by getting a patent from the Egyptian Patent Office (http://www.egypo.gov.eg/english/default.htm).
