A Solution to Stop Garbage Destroying Tourism

By David SouthDevelopment Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

Tourism is an essential source of income for countries across the South. But many put that livelihood in jeopardy when they lose control of garbage collection. A popular tourist spot can represent a ‘paradise’ to visitors, but when it becomes too popular and local garbage collection systems collapse under the burden, ‘paradise’ can soon turn to an environmental hell.

The small, tourist-friendly Indonesian island of Bali (http://en.wikipedia.org/wiki/Bali) – known for its idyllic pleasures of spas, surf and serenity – is being overwhelmed by garbage. A survey of tourists found two-thirds would not return to the island because of the problem.

Tourism took off on the island in the 1970s. The economic benefits are clear: the island went from being economically marginal to ranking second only to the country’s capital, Jakarta, in wealth creation. The island received more than 2.38 million tourists in 2009, up 14.5 percent compared with 2008, according to Ida Komang Wisnu, head of the provincial statistics office. But tourism produces on average five kilograms of waste a day per tourist – 10 times what the average Indonesian produces (Bali Fokus).

In the past, the traditional way of serving food in Indonesia was to wrap it in, or serve it on, a palm leaf: a biodegradable approach. But with the huge expansion in use of plastics and non-biodegradable packaging, the waste disposal problem is out of control.

In Indonesia, government garbage disposal services tend to collect between 30 and 40 percent of solid waste, most of this from high income communities. The majority poor population are left to fend for themselves when it comes to waste disposal.

A solution by Yuyun Ismawati, an environmental engineer and consultant, has since 1996 focused on helping poor communities find ways to safely dispose of waste. In 2000, she started her own NGO – Bali Fokus (http://balifokus.asia/balifokus/) – and opened a waste management facility in the Bali village of Temesi. The recycling plant employs 40 people from the village, who sort garbage into recyclables, compost and residual waste. Income from the recycled waste and compost goes to helping local farmers.

She then expanded her concept to include households around Bali and elsewhere in Indonesia. She concentrated on housewives and targeted reducing the amount of household waste going to dump sites. A core team trains housewives in daily habits that separate waste and compost organic matter like vegetable and fruit scraps. Bali Fokus claims it has been able to reduce waste created by 50 percent in 500 homes. Some of the women sell their compost in local markets; recyclables are turned into sellable items.

From 2001 to 2003, Ismawati turned this approach into a replicable template called SANIMAS. By 2008, the SANIMAS template was being used in hundreds of communities across Indonesia.

Her solution to the deluge of tourist waste can be seen in the luxury Jimbaran Bay area of Bali. Traditionally, the area’s hotels would sell their waste to pig farmers. While the pigs feasted on the fancy scraps, the rest of the waste was put in plastic bags and thrown away in mangrove forests.

“I told hotels: Your job is to sell rooms, not to sell garbage,” Ismawati recalls. “We have to protect Bali or else tourists won’t want to come here anymore.”

Ismawati cleverly turned the relationship around: rather than a pig farmer paying for scraps, she convinced one of them there was money to be made recycling and sorting garbage. For this, the hotels would pay the farmer.

A network of 25 hotels now pays to have their garbage taken away and sorted by hand: an important source of full-time jobs.

The workers sort through paper, plastics, glass, aluminium, food scraps and vegetables. Each week, 140 trucks deliver waste to the facility. Only 10 leave with waste that has to go to a dump site.

Food leftovers are bought by local pig farmers and grass clippings and other organic matter is composted (http://www.recyclenow.com/home_composting/), and eventually makes its way back to the hotels and is distributed in the flower beds.

This system has created 400 jobs where the pig farmer once only employed 10 people.

“If you want a hi-tech solution in a developing country you will wait and wait and wait until you get the money, or big donors to fund it,” Ismawati told the Telegraph newspaper. “And even then it may not work.”

A graphic example of this is a donated waste recycling machine given by the local government. It can’t be used because the electricity to power it costs too much. Human labour is a cheaper option.

Bali Fokus’ successful approach has now been replicated in six other sites on the nearby island of Java. And the government of Indonesia has promised to help create 15 more each year.

In 2009 Ismawati won the Goldman Award (http://www.goldmanprize.org/), which honors grassroots environmental heroes from the six inhabited continental regions: Africa, Asia, Europe, Islands and Island Nations, North America, and South and Central America.

She is also working on using decentralized grassroots approaches to bringing sewage disposal and clean water to communities.

Turning Animal Waste Into Paper

By David SouthDevelopment Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

Animal waste is a messy fact of daily life in rural communities across the global South. This byproduct of life has many uses – but an ingredient for making writing paper is probably not the first that springs to mind.

But animal dung is cleverly being recycled into high-value products in Sri Lanka and Thailand. Both countries have elephants who are under threat. In Sri Lanka (http://en.wikipedia.org/wiki/Sri_Lanka) the large but endangered elephant population is considered a nuisance. They damage crops and are often killed for this reason. There are upwards of 3,000 elephants in the country – down from 14,000 in the 1800s. Nonetheless, they create vast quantities of excrement. In Sri Lanka, they face many threats: ivory poachers, being killed to protect crops and houses, starvation from drought and deforestation.

Animal waste (http://en.wikipedia.org/wiki/Feces) has many uses: it can be turned into fertilizer for crops, fuel for cooking, placed in a digester and fermented into bio-gas for heating and cooking, and if from a herbivore animal, into fibrous products like paper and cardboard. Packing boxes can also be made from the excrement.

As a vegetarian animal, elephants’ excrement and dung is made up of vegetable matter and is rich in cellulose (http://en.wikipedia.org/wiki/Cellulose). And cellulose is what makes up the majority of traditional wood-pulp paper (http://en.wikipedia.org/wiki/Pulp_%28paper%29).

Re-using the waste is also a good way to make elephants valuable to local people, rather than just being perceived as a nuisance.

Dung produces a natural, recycled paper. While harvesting trees for paper is an expensive and energy-wasting process, the elephant’s digestive tract does the hard work by breaking down the cellulose, making it ideal for the next stage in becoming a paper product.

According to the Environmental Paper Network (http://www.environmentalpaper.org/stateofthepaperindustry/confirm.htm), 50 percent of the world’s forests have been destroyed, and 80 percent of the remaining forests are in a degraded state.  By turning to alternative sources to make paper, trees are saved and vast quantities of energy reduced. Traditional paper-making also uses many chemicals in the process, something that is avoided in using animal dung. Vegetable products are used to bind the paper together and water-soluble dyes are used to colour the paper.

Dung paper has earned some high-profile fans as well. The Turner Prize-winning British/Nigerian artist Chris Ofili (http://en.wikipedia.org/wiki/Chris_Ofili), uses elephant dung paper in his works.

The Elephant Dung Paper company (www.elephantdungpaper.com) in Thailand was one of the first to pioneer the technique. This business was started by dung paper pioneer Mr. Wan Chai. He tells a story of how he became enchanted by the paper-making process when he walked past a paper factory one day. Later, when he was at the Thai Elephant Conservation Center in Lampang, northern Thailand (http://www.changthai.com), he noticed the elephant dung was rich in fibres like those used in making paper from wood pulp.

Inspired, he embarked on a process of trial and error using his wife’s food processor to turn elephant dung into a fibrous stew that is then shaped, dyed and dried to make paper (http://www.elephantdungpaper.com/process.html).

Wan Chai has gone on to be a formative influence in the founding of a sheep dung paper making operation in Britain, Creative Paper Wales.

Another dung paper business is Mr. Ellie Pooh (http://www.mrelliepooh.com/) in Sri Lanka. Established with the goal of reducing conflict between humans and elephants, it has turned to making paper products to boost local incomes and create a direct economic incentive to protect the elephants. It is setting up handmade paper workshops in rural areas and teaming them with artisans to add value to the products and make them more desirable. Design is critical to making any product – no matter how ethically produced and how green – desirable to consumers.

The dung products Mr. Ellie Pooh makes include a wide variety of coloured papers, scrapbooks, note boxes, stationery pouches, greeting cards, ‘to do’ list pads, memo books, and a children’s book.

The process of making elephant dung paper takes about 13 days – three days of sorting, boiling and disinfecting, followed by 10 days to pulp, mix, press and dry the paper. Mr. Ellie Pooh makes about 1,000 sheets a day and 30,000 a month. Each sheet makes six A4-size pieces of paper.

The company was founded by Dr. Karl Wald and Thusitha Ranasinghe, and is managed by recycled paper firm Ecomaximus (http://www.ecomaximus.com/) based in Colombo, Sri Lanka, with a workshop in Kegalle.

Ecomaximus was started in 1997 by its Managing Director, Ranasinghe, who was following a family tradition going back three generations of working in printing.

The business started recycling waste printing paper and then moved into recycling a wide variety of other cellulose waste: rice paddy straw, cinnamon and banana bark. It now employs over 35 people on two sites.

It is proof that it just takes creativity and a new perspective to turn something considered as waste into wealth: and jobs and sustainable incomes.

Egyptian Youth Turns Plastic Waste into Fuel

By David SouthDevelopment 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).

Turning Human Waste to Fertilizer: An African Solution

By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

While South Africa has been free of the racist Apartheid regime since the mid-1990s, the expected boost to living standards for the majority black population has not been as widespread and as quick as many had expected.

One important aspect of lifting living standards is making sure the entire population has access to adequate sanitation and hygiene services. Another is making sure they have access to adequate and healthy food sources. A bright idea based on intensive research is meeting both goals in an innovative way.

According to the Council for Scientific and Industrial Research (http://www.csir.co.za/), some 11 million South Africans have received access to basic sanitation services since 1994 – but 13.3 million still lacked basic sanitation services by 2008.

The Water Research Commission (WRC) (http://www.wrc.org.za/) believes there is a crisis with South Africa’s toilet pit latrines, which are quickly filling up past their original design capacity. WRC’s solution is to turn the human faeces or faecal sludge deposited in pit latrines into fertilizer for farming and agriculture. The Water Research Commission is advocating using the fertilizer either for fruit trees or for trees that will be turned to income sources like paper and fuel.

The WRC’s project and series of experiments are called “What happens when pit latrines get full?”

“Only one third of municipalities have a budget to maintain on-site sanitation,” WRC researcher and scientist David Still told Inter Press Service (IPS). “If pits fill up, all the hard work that was done to address the sanitation backlog will be wasted. Why not use faecal sludge to address the growing problem of food insecurity by planting fruit trees? Or use the sludge to cultivate trees for fuel or paper production?”

Human faecal sludge contains a variety of nutrients, such as nitrogen, phosphates and potassium. The WRC estimates the average person excretes enough human faecal sludge per year to fertilize 300 to 400 square metres of crops.

The big reason people are reluctant to use human waste as fertilizer is because of the pathogens it contains. Spreading this on edible crops is dangerous and it is also a risk to groundwater when it leaches in to the soil.

The WRC conducted research on two sites: Umlazi and Karkloof, both in KwaZulu-Natal, South Africa. They used property owned by the South African Paper and Pulp Industry (SAPPI) and the local municipality.

The first step in the experiments was to bury the sludge in pits and plant crops on top of it. The pathogens were contained using this method and in time died off.

The test trenches were 0.75 metres in depth and filled with different quantities of sludge. Two control sites did not use faecal sludge. The scientists found the sites where the human waste was used saw plant growth and volume increase by “as much as 80 per cent.”

They then tested for pathogens in the soil. This included looking for the eggs of the large roundworm (http://www.nhs.uk/conditions/Roundworm/Pages/Introduction.aspx), a parasite whose presence would be harmful to humans. The site was tested over a period of 30 months, but none could be found.

Tests for microbes at the Umlazi site also found none. The plants were found to have healthy dark green leaves and the trees grew larger with the sludge present.

Researchers also monitored the groundwater around the sites. They found in flat ground and sandy soil there was no impact. In the site with sloping and shallow soil, small increases in nitrate were observed in the groundwater after rainfall.

They concluded the best place to apply this technique is in places that are flat and where the soil is deep.

One local resident, Lindiwe Khoza, was selected to be part of the test. Citrus and peach trees were planted on top of the buried sludge.

She told IPS: “The fruit grows much faster and it seems to be tastier and juicier than fruit bought at supermarkets. We now enjoy fruit from our own garden.”

WRC’s clever solution to these twin problems could help make life much more pleasant in communities still grappling with poor hygiene services, while dramatically improving the health of crops and their yields.
