Egyptian Youth Turns Plastic Waste into Fuel

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).

African Fuel Pioneer Uses Crisis to Innovate

Crisis, as the old saying goes, is also a window of opportunity. And there is one African entrepreneur who knows this better than most. Daniel Mugenga has been on a journey of innovation that has led him to become a pioneer in the emerging new field of algae technologies. The story of how he got there is a testament to the power of using business to both solve problems and make profits.

Kenyan entrepreneur Daniel Mugenga has found a solution to the problem of high fuel costs for the transport sector in his country. He has been making money from turning waste cooking oil and inedible vegetable oil into biodiesel (http://en.wikipedia.org/wiki/Biodiesel). He then discovered that he could boost his production of biodiesel by using marine algae as a source for oil.

According to the body that represents the algae fuel industry, Oilgae (oilgae.com), algae are “plant-like organisms that are usually photosynthetic and aquatic, but do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures. They are distributed worldwide in the sea, in freshwater and in wastewater. Most are microscopic, but some are quite large, e.g. some marine seaweeds that can exceed 50 m in length.”

The U.S. Department of Energy has been investigating algae as a fuel source since 1978, and it is being investigated as a potentially transformative fuel source around the world. His business, Pure Fuels Ltd. (http://www.purefuels.co.ke/), is currently seeking venture capital funding for expansion and innovation. Pure Fuels is “a commercial producer of biodiesel and also manufactures biodiesel processors, which we sell to budding entrepreneurs,” says Mugenga.

The Pure Fuels website educates readers on biodiesel as well as offering opportunities for investors and news updates. Pure Fuels was registered as a business in Kenya in 2010.

The business was born out of crisis: in 2008 there were frequent fuel shortages in Kenya and prices were volatile. That was bad news for Daniel Mugenga’s job, working for a transport company with a fleet of trucks. Rising or volatile fuel prices can destroy businesses in areas like trucking, where the biggest expense is fuel.

Mugenga began to do research into fuel alternatives in the crisis and came upon biodiesel. He then set about training in how to produce biodiesel. A period of testing, trials and research ensued between 2008 and 2010, which enabled Pure Fuels to build confidence they had something that was high  quality. The company started producing 120,000 litres of biodiesel in 2010 and increased production to 360,000 litres in 2011 and 700,000 so far in 2012. In 2011, Pure Fuels had revenue of US $230,000 from selling biodiesel.

“We started off using jatropha oil, but when its price went up it was no longer profitable,” Mugenga told the VC4Africa website blog. “Having invested in the machinery, we switched to the next quickest alternative which is used cooking oil. We source it from several of the tourist hotels along the Kenyan coast.”

Turning to cooking oil for biodiesel at first was a good idea. The company was able to get enough waste cooking oil from Kenya hotels and tourist resorts to meet demand. But as demand rose, the thorny problem of Kenya’s tourism business being seasonal arose.

“For about five months of the year, many hotels in Mombasa temporarily shut down or operate at lower capacity. Of course this is affecting the amount of waste cooking oil,” Mugenga said. This is where algae (http://en.wikipedia.org/wiki/Algae) comes in.

Pure Fuels found a biotechnologist in Kenya to help develop a solution using algae as a source for fuel. While the company is keeping details of its innovation secret, it is currently hunting for investors to help increase the quantity of biodiesel it can make – and in turn, revenues.

Investor funds would be used to import non-edible vegetable oil and also to continue the company’s work on extracting oil from marine algae.

Pure Fuels make a bold statement on algae fuel development: it “may actually be Kenya’s next cash crop.”

Pure Fuels sells several products: there is the biodiesel itself, as well as a processing machine called the GXP-200, which can turn customers into biodiesel manufacturers themselves. The company also builds large, industrial-scale processors that can produce between 1,000 litres and 5,000 litres a day.

Pure Fuels currently sells fuel to truck, bus and tuk-tuk companies, and also operates biofuel stations.

The firm has patented its biodiesel and makes all its fuel go through seven quality checks for purity. An in-house laboratory ensures adherence to international standards, and the company is certified by the Kenya Bureau of Standards (http://www.kebs.org/).

Mugenga is a passionate advocate of biodiesel’s advantages: he believes it is cheaper, and better for engines and for the environment. He admits it does have a disadvantage: it gels below 13 degrees Celsius and must be mixed 50-50 with conventional diesel to stay fluid.

Pure Fuels encourages others to use biofuels for business, throwing in a home training kit with the biodiesel processors it manufactures and sells, complete with DVDs, manuals and a business plan. The GXP-200 biodiesel processor was developed after years of experience, and Pure Fuels hopes it will be bought by people who then set up businesses – especially youth, women and the disabled. As a further incentive, Pure Fuels promises to buy the biodiesel produced. The GXP-200 was recently awarded “Most Innovative Product 2012″ at a small and medium business entrepreneurs event in Nairobi.

In Israel, there are a number of pioneers working on further developing algae as a biofuel source too. Isaac Berzin of Seambiotic (seambiotic.com) sees algae as a good source for biofuel because it does not compete with food crops like other biofuel sources (sugar, potatoes, corn etc.). Algae is among a group of so-called second-generation biofuels that includes jatropha, wood and castor plants.

The disadvantage of plant-based fuel sources is they need arable land and water. This seriously holds back their ability to meet the world’s demand for fuel since they would just take up too much land and water. Algae takes up less space and produces a higher yield per acre than conventional crops.

Seambiotic makes marine microalgae using the CO2 from electric power plant flue gas. It pioneered making large quantities of fuel algae in the United States, creating the first gallons of bio-diesel and bio-ethanol from marine microalgae.

Seambiotic is also working on a US $10 million commercial microalgae farm in China, partnering with China Guodian (http://www.cgdc.com.cn/), one of the country’s largest power companies. Another Israeli company in this field is UniVerve (http://www.univervebiofuel.com/). Its CEO, Ohad Zuckerman, runs the10-person company in Tel Aviv, Israel. It is developing a new biofuel from a special strain of algae that can grow quickly in a wider range of temperatures.

Urban Farming to Tackle Global Food Crisis

The world’s population is becoming more urban by the day. By 2030, some five billion people around the world will live in cities. This year is the tipping point: urban dwellers (3.3 billion people) now outnumber rural residents for the first time (UNFPA’s State of the World Population 2007 Report).

But with rising food prices across the globe, many city-dwellers are experiencing hunger and real hardship. On international commodity markets, food prices have gone up 54 percent over the last year, with cereal prices soaring 92 percent (FAO – World Food Situation). While living in an urban environment means living cheek-by-jowl with other people, it doesn’t mean there aren’t ways to grow food and supplement urban dwellers’ tight budgets and boost diets.

U.N. Secretary-General Ban Ki-moon has called for food production to increase 50 percent by 2030 just to meet rising demand – and right now there are 862 million people undernourished (FAO). But one solution, urban farming, can make a huge difference, as the Caribbean island of Cuba has shown.
Today, Cuba imports about 50 percent of its minimum fuel and food requirements – a cost that reached US $1.6 billion last year for food. (Reuters). The island has been buffeted by one food crisis after another in the past two decades, first by the collapse of its aid from the Soviet Union, and then by a fuel crisis. But now, urban farming in Cuba provides most of the country’s vegetables, thanks to urban gardens that have sprung up on abandoned land in the country’s cities and towns. And the food is pesticide-free: 70 percent of the vegetables and herbs on the island are organic (http://www.soilassociation.org/web/sa/saweb.nsf/Living/ whatisorganic.html).

These urban farms mean fresh food is just a short walk away from the people who eat it. And in a world of rising fuel prices, Cuba has reduced the use of fossil fuels in the production and transportation of food.

The urban farms have created 350,000 jobs that pay better than most government jobs. It has also improved Cuban’s health: many have moved from diets dominated by rice and beans and imported canned goods from Eastern Europe, to fresh vegetables and fruits.

While Cubans receive at least a basic state ration of rice, beans and cooking oil, the rations do not include fresh fruit and vegetables. After the withdrawal of Soviet subsidies, the average Cuban’s daily calorie intake fell sharply. Between 1989 and 1993, daily calorie intake dropped from 3,004 to 2,323 (UN). But with the growth of urban farms, this has moved up to 3,547 calories a day – even higher than the amount recommended for Americans by the US government.

The secret to this success has been the rise of entrepreneurs like Miladis Bouza, a 48-year-old former research biologist who had to abandon a comfortable middle class life after the collapse of the Soviet Union. Her government salary dropped to US $3 a month. Unable to make ends meet and provide food for her family, she quit her job.

The Cuban government allowed people to turn unused urban land into mini farms. The cities have many vacant lots because the state owns most land and there isn’t competition from private developers, as in many other countries. Unusually for communist Cuba, 80 percent of the profits are kept by the farmers. This can be an average wage of US $71 per month.

“Those salaries are higher than doctors, than lawyers,” Roberto Perez, an agronomist who runs the country’s first urban farm, told The Associated Press. “The more they produce, the more they make. That’s fundamental to get high productivity.”

Miladis grabbed this opportunity to farm a half-acre plot near her home in Havana. Along with her husband, she grows tomatoes, sweet potatoes and spinach, and sells the vegetables at a stall on nearby busy street. This has enabled her monthly income to rise to between US $100 per month and US $250 per month, far more than the average government salary of US $19 per month.

Cuba was inspired by greenbelt farms in Shanghai (http://en.shac.gov.cn/hjgl/jqgk/t20030805_82028.htm): but Cuba has gone even further to make urban farming a key part of the national food supply.

All this urban farming is also all-natural farming. Farms have had to turn to natural compost as fertilizer, and natural pesticides like strong-smelling celery to ward off insects.

So-called organoponicos (http://academicos.cualtos.udg.mx/Pecuarios/ PagWebEP/Lecturas/ORGANOPONICOS.htm ) gather together a wide variety of vegetables, fruits and herbs, as well as ornamental plants. Customers are offered mangos, plantains, basil, parsley, lettuce, garlic, celery, scallions, collard greens, black beans, watermelon, tomatoes, malanga, spinach and sweet potatoes.

“Nobody used to eat vegetables,” said David Leon, 50, buying two pounds of Swiss chard at a Havana organoponico. “People’s nutrition has improved a lot. It’s a lot healthier. And it tastes good.”

Bio-ethanol From Sturdy and Once-Unwanted Indian Plant

 

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.
