The problem with palm

Mother Nature Network (MNN)

Using palm oil to make biodiesel may cause more trouble than it prevents.

21/04/2009 (Mother Nature Network (MNN)) - As fears of global warming continue to rise with gas prices, both corporations and environmentalists are looking into alternative fuel sources. Now, businesses abroad plan to make biodiesel from palm oil, a substance found in common household items like cookies, shampoo, and margarine. Toyota Motor Corp. announced in May that it will partner with Japan’s Nippon Oil Corp. to develop biodiesel from palm oil, and the Malaysian government approved 54 projects this year alone to create B100, a biodiesel based from 100 percent palm oil, the country’s main export.

But while biofuels are cleaner-burning and produce fewer greenhouse gas emissions than regular fuel, some environmentalists believe the costs of palm oil-based biodiesel may outweigh the benefits.

The problem in Malaysia and Indonesia, where more than 80 percent of the world’s palm oil is produced, is that in most cases, rainforest areas are completely cleared to create oil palm plantations. According to a 2005 Friends of the Earth report, oil palm plantations have been responsible for about 87 percent of the rainforest deforestation in Malaysia.

Not only does this practice wreak havoc on the countries’ megafauna (such as orangutans, Sumatran rhinos and tigers, Asian elephants, gibbons, and tapirs), it also causes significant pollution. The United Nations’ Food and Agriculture Organization estimates that 25 to 30 percent of the greenhouse gases released into the atmosphere each year (about 1.6 billion tons) comes from deforestation.

“When you turn a product into a world commodity, you get corporations involved,” says Tim Keating, executive director of Rainforest Relief. “Originally palm oil was collected by hand, but once you get corporations involved, you end up having forest clearing and mass plantations.”

Corporations first clear the land for its lucrative timber. Then they burn everything that’s left on the land, such as shrubs, stumps, and peat soil, which can smolder for three to four months before it’s finally extinguished, says Michelle Desilets, director of the Borneo Orangutan Survival Foundation, UK. Tree-felling combined with the burning creates a haze above the forest and releases tons of carbon dioxide into the atmosphere, contributing to the same global warming that biofuels are supposed to reduce.

Since Indonesian and Malaysian rainforests are some of the most diverse ecosystems on the planet, clearing these areas poses serious threat to countless species of plants and animals. Right now palm oil is mostly used in food products. But if the demand for palm oil-based biodiesel increases, the oil palm business will certainly expand, creating more deforestation and species destruction.

But despite the huge environmental impact palm oil-based biodiesel has, businesses interested in bottom-line dollars see a market for it.

“Palm oil is the cheapest source for biofuel, and, as we know, in the marketplace the cheapest wins,” said Shannon Coughlin, program director for Rainforest Action Network, in an e-mail.

Leland Tong, an advisor to the National Biodiesel Board, says though palm oil is not grown domestically and will not lessen dependence on foreign fuel sources, it does offer some perks as far as biofuels go. It has a higher freezing point than regular fuel alone; it’s renewable; and it’s similar in efficiency to other biofuel sources such as soybean oil.

Rainforest advocates suggest some more environmentally responsible alternatives to making biodiesel from palm oil. Desilets asserts that if there must be palm oil plantations, then they should be planted on already degraded land (such as rainforest that has been logged, but not cleared) to protect other high-conservation areas. Keating insists that the only solution is to lessen our dependence on fuel. And Coughlin suggests making ethanol from agricultural waste and switchgrass so that no land has to be cleared. But all agree that the current method of producing palm oil-based biodiesel is not the answer to our energy needs.

“We know that an increased market for palm oil imports will accelerate rather than stop climate change,” said Coughlin in an e-mail. “It’s crazy. We need to break the addiction rather than keep feeding it.”

Elephant grass could be the fuel of tomorrow


Scientists at one of Wales' top universities will use elephant grass to create clean and sustainable fuel, The Western Mail reports. The £27 million project is among the largest ever to be undertaken.

Along with academics from Rothamsted Research, Imperial College London and Cambridge University will try to increase its yield, which stands at 12 mt per hectare. When combusted as coal, one hectare of elephant grass, produces enough fuel to save up to 7 mt of C02 being released into the atmosphere.

German chemical group Basf said it has developed a new generation of genetically altered crops, by precisely manipulating the plant’s own DNA, the Financial Times reports. This allows the introduction of new traits such as herbicide resistance similar to traditional genetic modification.

However, as no genes are added, the technology, known as ‘directed mutagenesis’ is likely to avoid the political and regulatory objections that have held up the introduction of gm crops, especially in Europe.

The UK Business Secretary announced £2.5 billion support for the car industry, of which £2.3 billion will be in the form of loans to be used only for research and development in low carbon technology.

Impact of oil palm cultivation - Straits Times, Singapore

12/05/2009 (Straits Times, Singapore), - PALM oil plantations are responsible for deforestation and biodiversity loss in Malaysia and Indonesia, scientists say.

But, they add, these can be managed to a limited extent.

Together, Malaysia and Indonesia produce about 80 per cent of the world's palm oil, which has a variety of uses - for food, fuel, the cosmetics industry and others.

Last year, Malaysia produced just under 22 million metric tonnes of palm oil, worth RM65 billion (S$27 billion), and Indonesia is fast catching up.

And as demand for alternative fuels to cut carbon emissions rises, so does demand for palm oil, which can be used for biodiesel.

But Singaporean scientist Koh Lian Pin said that between 1990 and 2005, 55 to 59 per cent, or 0.8 million to 1.1 million hectares, of Malaysia's new oil palm developments were cultivated on former forest lands - meaning that forests were being cut down for plantations.

The same was true of Indonesia, with over half of new oil palm plantations in the same period coming from forests.

Dr Koh, now a research fellow at Swiss technological institute ETH Zurich, presented his findings at a conference at the National University of Singapore (NUS) on Tuesday.

At the conference, organised by Yale University, the Smithsonian Tropical Research Institute and NUS, industry players, scientists and NGOs, discussed the impact of oil palm cultivation.

Dr Koh also surveyed the number of bird and butterfly species in oil palm estates, and noted that plantations generally held just a quarter of the species contained in primary forests.

He recommended measures to safeguard biodiversity, such as expanding plantations only into non-forested areas, and protecting primary and secondary forest.

Responding to Dr Koh's comments, Dr Kalyana Sundram of the Malaysian Palm Oil Council said the council had a RM20 million (S$8.3 million) grant to fund wildlife conservation projects.
