Summary: In order to produce high-quality biodiesel, it is necessary to fractionate polyunsaturated fatty acids (PUFA). The study aimed to separate linoleic acid from CPO and determine the best conditions for the separation process to produce fatty acids with low iodine numbers. The results showed that the fractionation method at a temperature of 35 degrees C, an extraction time of 4 h, and a ratio of CPO and solvent of 1:3 produced fatty acids with low iodine numbers and high oxidation stability.

Summary: The study assessed the land use impacts from oil palm plantations in the five regions of Thailand, with the southern region identified as the most suitable for further expansion. Unsuitable management in the past resulted in land use impacts such as increased greenhouse gas emissions and water scarcity. Suitable practices are important for sustainable oil palm plantations to reduce these impacts in the long run.

Summary: Engine oil's lubricity and tribological properties are changed when diluted with unburned fuels. The study shows that diluted lubricating oil results in increased friction and wear, with different fuels having varying degrees of influence, and the impact of quaternary fuel blends is relatively small.

Summary: The experimental investigation of the laminar lifted flame of pre-vaporized palm oil biodiesel revealed that the liftoff height is influenced by jet flow velocity, fuel mole fraction, and unburnt gas temperature, with a limited range of conditions for lifted flame occurrence. In some cases, flames experienced liftoff even at lower jet velocities, believed to be due to buoyant force at the nozzle causing secondary entrainment of the mixture flow. The correlation between liftoff height, jet flow velocity, and stoichiometric laminar burning velocity highlights the significance of buoyant force near the nozzle exit.

Summary: Current consumption of palm oil accounts for one third of the growing world demand for vegetable oil, leading to huge ecological costs due to rapid oil palm expansion in many parts of the world within just three decades. A study identified approximately 4.5 million hectares of available land in Malaysia and Indonesia for new plantations, providing 1.3 million tonnes per year of sustainable palm oil.

Summary: Different strategies for meeting Legal Reserve targets in Brazil, including on-site/off-site protection and/or restoration, were evaluated to minimize the need for restoring native vegetation on productive farmland. Moderate ecological equivalence rules were found to be cost-effective and successful in achieving conservation goals without impacting agricultural lands in most states of Brazil.

Summary: Consumer countries are introducing legal measures to tackle deforestation, but relying solely on legality criteria is insufficient to fully protect forests and ecosystems. This approach may even exacerbate deforestation and conversion risks by inadvertently incentivizing producer countries to weaken social-environmental protections.

Summary: Natural ecosystems worldwide are facing severe threats, and environmental policies are crucial in protecting biodiversity, ecosystem services, and addressing climate change. The New Forest Act in Brazil is a key policy for conserving native vegetation on private lands, which account for 54% of the remaining Brazilian native vegetation. However, conflicts between environmental and agricultural concerns hinder the implementation of the Act, highlighting the need for balanced solutions based on scientific evidence.
