BIO-ENERGY BASE MATERIALS AT YOUR DOORSTEP
BIO - MATERIALS
Used cooking oils come mainly from restaurants and food chains. The majority of these waste oils are thrown away as waste, without being treated, with dramatic consequences for the environment.
Alternatively, waste oils can be treated and converted to biodiesel.
We offer UCO according to the following specifications:
Crude UCO: FFA 5% max | MIU 2% max | IV 80 min | Sulfur ppm 40 max
Refined UCO: FFA:2- 3% max | M&I: 1% max | IV 90 min | Sulfur 30 max
Animal fat feedstocks can be processed and turned into high-quality biodiesel. They are also added to pet food and animal feed, and used for industrial purposes such as soap making.
Animal fats are highly saturated, hence they solidify at a relatively high temperature. Therefore, biodiesel made from animal fat has a high cloud point. From a theoretical standpoint, the saturated fatty acids in animal fats should contribute to better oxidative stability for biodiesel. In fact, animal fats contain only small amounts of polyunsaturated fatty acids, such as linoleic acid and linolenic acid, that make vegetable oils such as soybean oil and linseed oil so prone to rancidity. However, animal fats are not always more stable than vegetable oils, as the latter are often more rich in natural anti-oxidants (e.g., a test of the peroxide content of lard and vegetable oil showed that the lard experienced oxidation faster than the vegetable oil).
We offer animal fats meeting the following specifications:
Quality: CAT 1, CAT 2 or CAT 3.
BIO - FUELS
Biodiesel is an alternative to conventional diesel fuel made from renewable resources, such as non-edible vegetable oils and animal fats. No engine modifications are required to use biodiesel in place of petroleum-based diesel.
Biodiesel can be mixed with petroleum-based diesel in any proportion.
Today's interest in Biodiesel is caused by a number of properties including the fact that biodiesel can be produced from a renewable domestic source, it is biodegradable, and has potential to reduce exhaust emissions. The climate change is presently an important element of energy use and development. Biodiesel is considered "climate neutral" because all of the carbon dioxide released during consumption had been sequestered out of the atmosphere during crop growth. The use of biodiesel resulted in lower emissions of unburned hydrocarbons, carbon monoxide, and particulate matter.
Fatty acid methyl ester, FAME, is a nontoxic, biodegradable biodiesel that can be produced from a wide array of vegetable oils and fats. It is used both as a blending component in fossil diesel and as a pure fuel. It is then called B100 (see separate fact sheet). FAME and bioethanol are the leading renewable liquid fuels globally. In Sweden, FAME is the second largest renewable liquid fuel on the market. All FAME available on the Swedish market is based on rapeseed methyl ester (RME) to comply with climate related requirements.
Fatty acid methyl ester is used as fuel in diesel engine vehicles. It is normally used as a blend-in component in fossil diesel to increase the renewable content of the fuel. The current European diesel standard allows up to 7% v/v of FAME in diesel fuel without any modifications in vehicles or the distribution system. FAME is fully miscible with fossil diesel and apart from increasing the renewable content, it improves the lubricating properties. However, FAME is sensitive to cold climate and is distributed in different variations depending on the climate zone of the distribution area. In Sweden, most variation tolerate operation down to -20°C.
Rapeseed oil methyl esters are important alternative diesel fuels based on renewable sources. Vegetable oils such as RME have an ignition quality equivalent to diesel fuel and their combustion characteristics are much similar to traditional fossil-fuels. Multiple research works on Rapeseed Methyl Easter ’’RME’’ used as fuel in unmodified diesel engines shows high friction power with a net reduction in hydrocarbon emissions. The carbon deposits on the injector in these analysis were similar to those observed when running on diesel fuel.
HVO is marked as the highest quality diesel in the world. HVO is produced through the process of hydrogenation (treatment with hydrogen) while regular biodiesel is produced through esterification (treatment with methanol). The by-products of the processes also differ, as propane and glycerine are the by-products of the hydrogenation and the esterification processes, respectively. What makes HVO the highest quality diesel in the world is the lack of oxidation, which is prevented by the hydrogenation process, through the removal of any traces of oxygen from the vegetable oil.
