Synthetic Palm Oil | Earth Wise

February 18, 2022 By EarthWise Leave a Comment

Palm oil is the world’s cheapest and most widely used vegetable oil.  Producing it is a primary driver of deforestation and biodiversity loss in the tropics.  In Borneo, for example, oil palm cultivation has accounted for more than half of all deforestation over the past two decades.   More than one million square miles of biodiversity hotspots could be threatened by oil palm cultivation, which could potentially affect more than 40% of all threatened bird, mammal, and amphibian species.

Today, the world consumes over 70 million tons of palm oil each year, used in products ranging from toothpaste and oat milk to biodiesel and laundry detergent.

Given this situation, there are now multiple companies developing microbial oils that might offer an alternative to palm oil while avoiding its most destructive impacts.

A company called C16 Biosciences is working on the problem in Manhattan, backed by $20 million from a Bill Gates’ climate solutions investment fund.  A California-based startup called Kiverdi is working to manufacture yeast oil using carbon captured from the atmosphere. 

Xylome, a Wisconsin-based startup is working to produce a palm oil alternative that they call “Yoil”, produced by a proprietary strain of yeast.  The oil from the yeast strain is remarkably similar to palm oil. 

The challenge is to be able to produce microbial oils at large scale and at a competitive price.  Unless valuable co-products could be manufactured along with the oil, it may be difficult to compete with palm oil.  Without regulatory pressures and willingness of consumers to pay more, it may be difficult to replace palm oil in many of its applications.

Increasing Palm Oil Production Without Harming The Environment | Earth Wise

May 5, 2021 By EarthWise Leave a Comment

Sustainable palm production is possible

Palm oil is the most important source of vegetable oil in the world.  The oil itself and ingredients based on it are found in approximately 50% of the products on supermarket shelves, including both food and non-food items.  Many of the mysterious chemicals that show up on ingredient lists such as sodium lauryl sulfate are actually derived from palm oil.

Dozens of countries produce palm oil, but about 2/3 of the world’s supply comes from Indonesia and the demand for its oil keeps growing.  To keep up with that demand, Indonesia continues to convert valuable ecosystems that contribute greatly to biodiversity to palm production.

A four-year research project at the University of Nebraska- Lincoln has found that keeping up with palm oil demand may not necessarily mean converting valuable, fragile ecosystems into agricultural land.  According to the study published in Nature Sustainability, palm oil yields on existing farms and plantations could be greatly increased with improved management practices.

The researchers identified key practices that could lead to larger yield.  These include improved harvest methods, better weed control, improved pruning, and better plant nutrition.  With such practices, Indonesia could produce 68% more palm oil on existing plantation areas.

The results were surprising to the researchers and are significant from both environmental and economic standpoints.  In particular, it could have a great impact on the millions of individual farmers who draw their livelihood from small palm farms often containing just a few acres.  In Indonesia, about 42% of land used for palm oil production is owned by smallholder farms.

The researchers are now working with various stakeholders in Indonesia to put these management techniques into practice.

A Palm Oil Replacement | Earth Wise

December 15, 2020 By EarthWise Leave a Comment

A possible replacement for palm oil

In the 1990s, cardiovascular health issues associated with partially hydrogenated oils containing harmful trans fats became a focus of great concern.  As a result, food companies looked for substitutes and the alternative they identified was palm oil.  Its ability to remain solid at room temperature made it well suited for many food applications.  Unfortunately, that property stems from its high saturated fat content, which means it also increases the risk of coronary heart disease.

The widespread use of palm oil has also caused significant environmental problems.  Palm oil plantations have replaced millions of acres of tropical forests, destroying the habitat for numerous species and threatening biodiversity.

Other potential replacements for partially hydrogenated oils such as coconut oil tend to be more costly, limited in supply, and also high in saturated fats.

Food scientists at the University of Guelph in Ontario, Canada, recently demonstrated the use of enzymatic glycerolysis (EG) to turn liquid vegetable oils into solid fats.  Their process is able to produce solid fats with the textural and structural properties desired by consumers.

The process is fairly simple, relatively easy to scale up, and is amenable to smaller food production or even local production.  Using it would enable food producers to use all sorts of readily available vegetable oils that can be produced in parts of the world that are not necessarily tropical regions.

Palm oil use is not going to go away, but this work may point a way to help slow down the destruction of ecosystems and animal habitats as well lead to more sustainable and healthy food sources.

Indonesian Deforestation

February 28, 2019 By EarthWise Leave a Comment

Deforestation is defined as the intentional destruction of trees and other vegetation without reforesting or allowing the forest to regenerate itself. 

In Indonesia, industrial agriculture, primarily for the production of palm oil, is a major driver of deforestation.  But, according to researchers at Duke University, its impact has diminished  proportionately in recent years as other natural and human causes have emerged. Their peer-reviewed findings were recently published in the journal Environmental Research Letters.

According to the study’s lead author, large-scale plantations were responsible for more than half of Indonesia’s deforestation in the late 2000s, peaking between 2008-2010 when an average of 1.5 million acres of forest was lost annually.  The expansion of the massive plantations was responsible for 57% of the forest loss. Between 2014-2016, an average of more than 2 million acres of forest was lost annually, but plantation expansion only accounted for 25% of this figure.  While the overall rate of deforestation continued to grow, other factors were responsible for most of it.

Conversions of forests to grasslands rose sharply in 2015 and 2016 when El Nino caused severe droughts and forest fires. Small-scale farming, often overshadowed by industrial agriculture, was also found to play a bigger role, accounting for 25% of all forest loss. 

Indonesia has experienced some of the highest rates of deforestation.  Its forests absorb and store vast amounts of climate-warming carbon dioxide, help prevent erosion and flooding, and provide habitat to thousands of species.  Understanding the varied causes of Indonesian deforestation should help conservationists and policymakers better address the problem.

Deforestation-Free Palm Oil

Few of us cook with palm oil or have ever even seen the stuff.  Nevertheless, 50% of all packaged grocery items – everything from ice cream and pizza to detergents and cosmetics – include it as an ingredient.  The global market for palm oil was $65 billion in 2015, and that number was projected to grow by more than 7% each year through 2021.

According to the Roundtable on Sustainable Palm Oil or RSPO, almost 12 million tons, or 21% of the global supply of palm oil, is now certified as responsible and sustainable.  The massive expansion of palm oil plantations has been one of the primary causes of global deforestation.  This has been especially the case in Borneo, where 85% of global palm oil production takes place.

Borneo is the third-largest island in the world, home to part of Indonesia, part of Malaysia, and the small sultanate of Brunei.   It is also home to the oldest forest on earth – 130 million years old – which is more than twice as old as the Amazon rain forest.
