OUR PARTNERS
Our Products
Amarus is a one stop-shop for Biofuel products. Amarus sources and trades a wide spectrum of feedstocks for the renewable industry with its main product range being biofuel feedstocks & bioproducts
Empty Fruit Bunches (EFB)
Empty Fruit Bunches are a by-product of palm oil production, consisting of the fibrous husks left after the extraction of palm fruit. They are rich in lignocellulosic materials, primarily cellulose, hemicellulose, and lignin, making them a valuable biomass resource for energy production. EFB can be converted into biofuels through processes such as pyrolysis and hydrothermal treatment, yielding bio-oil and reducing sugars that can serve as renewable energy sources. Additionally, EFB is utilized as a biomass fuel or fertilizer in agriculture due to its nutrient content and organic matter. The increasing generation of EFB presents opportunities for sustainable waste management and energy production within the palm oil industry.
Spent Bleaching Earth (SBE)
Spent bleaching earth is a byproduct generated during the refining of vegetable oils, primarily used to remove color pigments and impurities from crude oils. Each year, the U.S. alone produces over 112 million pounds of this material, which retains approximately 30-50% of the edible oil processed, resulting in significant economic losses due to the value of the oil trapped within the clay. The disposal of spent bleaching earth poses environmental challenges, particularly due to its susceptibility to spontaneous combustion when exposed to air, necessitating careful handling and immediate covering upon disposal. Recent innovations aim to mitigate these issues by mixing SBE with additives like salt or lime, transforming it into safe products for livestock feed and preventing combustion risks. This approach not only enhances the economic viability of spent bleaching earth but also contributes to sustainable waste management practices within the vegetable oil industry.
Brown Grease
Brown grease, primarily derived from food preparation waste, is increasingly recognized as a valuable feedstock for biodiesel production. It consists of fats, oils, and greases (FOG) collected from sources like grease traps in restaurants, making it distinct from other waste oils. Recent regulatory updates by the International Sustainability and Carbon Certification (ISCC) have clarified that only material removed from grease traps qualifies as brown grease, excluding oils sourced from sewage systems. This classification has implications for biodiesel producers in China, where the availability of such feedstock is limited, potentially affecting production levels. The use of brown grease in biodiesel not only helps reduce waste but also contributes to lower carbon emissions, promoting a more sustainable energy landscape
Soapstock Oil
Soapstock oil is a by-product generated during the refining of vegetable oils, primarily during the neutralization process where free fatty acids (FFAs) are removed. This by-product typically consists of soap, neutral oil, and a significant amount of water, often around 80%. While soapstock was traditionally viewed as waste, it is now recognized for its potential value ; it can be processed into acid oil through a splitting procedure that liberates fatty acids and unreacted glycerides. The resulting acid oil can be utilized in various applications, including the production of biodiesel and other industrial chemicals, thereby
enhancing the sustainability of vegetable oil refining processes
Palm Oil Mill Effluent (POME)
During crushing of Fresh Fruit Bunches (FFB) to produce CPO, large quantities of steam and hot water are used to separate the palm fruit from the FFB. Such hot water is let out into open ponds, and this is known as Palm Oil Mill Effluent (POME). POME is non-toxic waste, as no chemical is added during the oil extraction process. This POME is skimmed from the surface, cleaned to reduce Moisture & Impurities and sold as POME or Sludge Palm OIL (SPO) or Palm Acid Oil (PAO).
In recent years, POME is also gaining prominence as a feedstock for biodiesel production, especially in the European Union. The use of POME as a feedstock in biodiesel plants requires that the plant has an esterification unit in the back-end to prepare the feedstock and to breakdown the FFA.
POME is an International Sustainability & Carbon Certification body (ISCC) certified product and is eligible for double counting.
Used Cooking Oil (UCO)
Used cooking oil is the leftover oil that remains after frying or cooking food, often containing food particles, contaminants, and degraded compounds. It typically has a dark colour and a strong odour due to the breakdown of fats and the absorption of flavors from the cooked items. When disposed of improperly, used cooking oil can cause environmental issues, such as clogging sewage systems and harming aquatic ecosystems. However, it can also be repurposed for various applications, including biodiesel production, animal feed, and industrial lubricants. Proper recycling and disposal methods are essential to minimize its negative impact on the environment.
Biodiesel
Biodiesel is primarily produced from vegetable oils, animal fats, recycled cooking oils or other waste vegetable oil products, through a chemical process called transesterification. In this process, the oil or fat reacts with a short-chain alcohol (typically methanol) in the presence of a catalyst, usually sodium hydroxide or potassium hydroxide. The reaction
breaks down the triglycerides in the oils/fats into fatty acid methyl esters (FAME), which constitute biodiesel, and glycerol as a byproduct. After the reaction, the biodiesel is separated from the glycerol, and then undergoes purification steps to remove impurities like soap, excess alcohol, and water. The final product must meet specific quality standards, such as ASTM D6751 in the United States, or EN14214 in Europe to ensure its suitability as a fuel for diesel engines
Hydrotreated Vegetable Oil (HVO)
Hydrotreated vegetable oil is a renewable diesel fuel produced from various feedstocks, including vegetable oils, animal fats, and used cooking oils. The production process involves pre-treating the feedstock, followed by hydrotreatment, where it reacts with hydrogen at high temperatures and pressures to remove oxygen. This process produces straight-chain hydrocarbons through hydrodeoxygenation and isomerization, resulting in a high-quality diesel fuel. HVO has superior cold flow properties and a higher cetane number compared to traditional biodiesel. It can be used as a drop-in fuel in existing diesel engines without modifications and is free of sulphur and aromatics.
Sustainable Aviation Fuel (SAF)
Sustainable Aviation Fuel is produced from renewable feedstocks like vegetable oils, animal fats, and agricultural residues. The most common production method is Hydroprocessed Esters and Fatty Acids (HEFA), which converts oils and fats into hydrocarbon fuels using hydrogen. Other pathways include Fischer-Tropsch synthesis and alcohol-to-jet processes, each utilizing different feedstocks. SAF must meet strict quality standards and can be blended with conventional jet fuel, typically up to a 50% ratio. The production process involves feedstock pretreatment, conversion reactions, and product purification.
