The production of algae-based biodiesel has been shown to reduce greenhouse gas emissions by avoiding the use of fossil resources. Additionally, establishing an algal biodiesel plant could create up to 45 jobs in rural areas and provide opportunities for diversifying agricultural sectors.
A study led by University of Wisconsin-Madison researchers found global yields of biofuels crops to be overestimated by 100-150%, highlighting the need for more realistic expectations. This information can empower countries to make informed decisions about agricultural biofuels.
The National Institute of Standards and Technology (NIST) has developed a new method to accelerate stability testing of biodiesel fuel made from soybeans. The 'advanced distillation curve' method identifies additives that enhance stability at high temperatures, which can cause biodiesel to break down.
The US Department of Energy Joint Genome Institute has released a complete draft assembly of the soybean genetic code, making it available to researchers. Preliminary studies suggest that the soybean genome contains as many as 66,000 genes, more than twice the number identified in the human genome.
Researchers will screen different types of algae to learn which species produce the most oil and grow them in large numbers to produce biodiesel. Algae have benefits that make farming them easier on growers, such as being able to use non-prime agricultural land and water not suitable for food crops.
A Virginia Tech researcher has developed a novel fermentation process using microalgae to produce omega-3 fatty acids from crude glycerol, a byproduct of the emerging biodiesel industry. The resulting algae biomass can be used as animal feed, mimicking a natural process where fish retain healthful compounds.
Chemical engineers at Rice University have unveiled a set of techniques for cleanly converting glycerin, a major biofuels waste byproduct, into high-value organic acids such as succinate and formate. The new fermentation process uses E. coli bacteria to convert glycerin into these valuable chemicals.
A study by Woods Hole Oceanographic Institution researchers found that retail biofuel samples often do not contain the advertised amount of biofuel. The actual percentage of biofuel in blends like B20 ranged from 10 to 74 percent, while only 10% met US Department of Defense standards.
A new method to convert low-value glycerol from biodiesel production into a hydrogen-rich gas offers a promising solution for the transportation sector. The process, developed by Dr. Valerie Dupont and her team at the University of Leeds, produces a high-value product in demand for fertilisers, food production, and chemical plants.
The CSIRO report found that biodiesel produced from used cooking oil can reduce emissions by up to 87%, while palm oil sourced from pre-1990 plantations can achieve an 80% emission reduction. This could lead to improved air quality and reduced health risks.
