ADA-Approved and Non-Appproved by Mike Marshall On March 15, 2011 The U.S. DEPARTMENT OF JUSTICE 2010 ADA Standards go into effect with specific new Artificial grass installed over a proper base can provide an ASTM safety rating for fall heights up to 12 feet. Since then, seven process pathways to SAF have been cleared through the ASTM process. Currently, sustainable aviation fuels can be approved at blends of up to 50%, says Mark Rumizen, senior technical specialist aviation fuels & propulsion lubricants, at the U.S. Federal Aviation Administration (FAA). Biodiesel, renewable diesel, jet fuel and heating oil. NREL's formula for SAF from wet waste is compatible with existing jet engines, making it a promising candidate for quickly getting approved by ASTM International. Trans-Esterification using natural gas or biomass for process energy. Fermentation using natural gas, biomass, or biogas for process energy. The team is proud to announce that ASTM The The NREL SAF pathway from food waste is a very promising candidate for ASTM International D4054 Fast Track evaluation, said Josh Heyne, an As more SAF pathways are approved, the opportunity for SAF volumes grows at airports worldwide. Currently there are six approved methods of creating SAF which are known as production pathways. RSB worked with Agroicone to examine the availability of residues and strategic locations for SAF production and consumption in Brazil. Every SAF pathway that is in D7566 is in there because the industry, including GE and CFM, already approved it. This practice covers and provides a framework for the qualification and approval of new fuels and new fuel additives for use in commercial and military aviation gas turbine engines . (GreenAir Online) Fuel standards organisation ASTM International has approved the seventh technology pathway for the production and use of sustainable aviation fuel (SAF). 2/ SAF pathways and developments Currently there are five pathways for SAFs production approved by ASTM International: Hydroprocessed Esters and Fatty Acids (HEFA), Gasification and Fischer-Tropsch (FT), Alcohol to Jet (ATJ), Hydroprocessed Fermented Sugars Olefins and oxygenates (reactive compound classes) allow for easier refining pathways, while the atmospheric residue fractions can also be converted into transportation fuels .

The pathways comprised ASTM-approved processes (HEFA, ATJ, and FT) and strategic feedstocks such as sugarcane (SC), soybean, palm, used cooking oil (UCO), beef tallow, agricultural and forestry residues (FR), and steel off-gases. The team is proud to announce that ASTM International has approved the new production pathway for Sustainable Aviation Fuel (SAF) called Catalytic Hydrothermolysis Jet, or CHJ. SAF technical certifications pathways derived hydrocarbons At present, the key criteria for industry is the ability of the SAF to be dropped-in to conventional jet fuel, with a maximum limit of 50% of the blend. vii . Today there are four ASTM-approved SAFs based on iso-alkanes ( Figure 14). The fuels are prepared by (1) cracking and isomerizing larger alkanes derived from lipids or FT liquids, (2) building up small molecules (alkenes) to the jet range, or (3) fermenting sugar into molecules that are in (or near) the jet range. Global standards-development organization ASTM International has approved another pathway to the production of sustainable aviation fuel (SAF). ASTM International has approved and published a sixth pathway for the production of sustainable aviation fuel (SAF). The Annex A7 represents the seventh approved pathway for the production of SAF: - Annex A1: Fischer-Tropsch Synthetic Paraffinic Kerosene (FT SPK). It represents the seventh approved pathway for the production of SAF. Digital presence: Access to a 365-day online community, featuring training, content and market intelligence. VFA ketonization models assessed the carbon chain length distributions suitable for each VFA-SAF conversion pathway, and food wastederived VFA ketonization was demonstrated for >100 h of time on stream at approximately theoretical yield. This includes championing new jet fuels successfully moving from laboratory scale to ASTM D4054 approval processes to commercial realities. In the United States (US), Applied Research Associates, Inc.

Dedicated SAF Masterclass detailing the pathways, business and economics of SAF. ASTM D4054 - Standard Practice for Qualification and Approval of New Aviation Turbine Fuels. Production pathways. Currently, seven SAF pathways or fuel categories have been approved under the ASTM D7566 standard. Sustainable aviation fuels (SAF) are renewable or waste-derived aviation fuels that meets sustainability criteria (reference: Annex 16 Volume IV).They are one element of the ICAO basket of measures to reduce aviation emissions, which also includes technology and standards, operational improvements, and the Carbon Offsetting and Reduction Scheme for International Page 3 - Playground Surfacing Materials. The seventh pathway for SAF production, HC-HEFA, was approved in May 2020 as Annex 7 to ASTMs SAF specification D7566, which establishes criteria for the production of a type of synthesized paraffinic kerosene from hydrocarbon-hydroprocessed esters and fatty acids (Green Car Congress, 2020). SAF is a blended fuel that is comprised of conventional Jet A/A-1 fuels mixed with a non-con-ventional sustainable blending agent (neat SAF) produced via one of seven following ASTM-approved pathways: 1. Today, this type of SAF is known as PtL, and it boasts improved combustion properties that could help significantly reduce emissions across We approved seven SAF production pathways. In process SAF Pathways, via D4054 process Additional technologies applicable to The specification D7566 covers the manufacture of aviation turbine fuel that consists of conventional and synthetic blending components. Although there are currently seven ASTM-approved SAF production pathways, availability of the required feedstock and increased costs compared to conventional jet fuels pose major challenges for a fast market uptake. ASTM International has approved a new production pathway for sustainable aviation fuel (SAF), created by Applied Research Associates (ARA) and Chevron Lummus Global (CLG). The new production pathway, which is called catalytic hydrothermolysis jet (CHJ), is expected to help meet the global need for more sustainable aviation fuels. The seven approved pathways (found in the D7566 Annexes) are: Conventional Jet A meets ASTM D1655, where SAF, when it's first produced, would meet ASTM D7566. Table 1 to 80.1426Applicable D Codes for Each Fuel Pathway for Use in Generating RINs. This review quantifies available regional feedstock suitable for ASTM-approved path-ways for producing SAF. Although fully formulated, 100 percent SAF requires an industry-approved standardsuch as that set by the ASTMbefore it becomes available for commercial use. Grant Request Information (Ongoing Project) GENERAL INFORMATION ASTM spec: D7566 Annex 3. SAF that is approved through the ASTM process meets the performance, operability and infrastructure compatibility requirements of traditional jet fuel. VFA ketonization models assessed the carbon chain length distributions suitable for each VFA-SAF conversion pathway, and food wastederived VFA ketonization was demonstrated for >100 h of time on stream at approximately theoretical yield. certifications are approved by ASTM increasing the approved technical pathways for SAF production to seven. RSB worked with Agroicone to examine the availability of residues and strategic locations for SAF production and consumption in Brazil. There is an increasing amount of discussion on the use and approval of a 100% SAF that does not need to be blended, he says. Annex A7 to ASTMs SAF specification D7566 establishes approval for a type of synthesised paraffinic kerosene derived from hydroprocessed hydrocarbons, esters and fatty acids. It represents the sixth approved pathway for the production of SAF. As more SAF pathways are approved, the opportunity for SAF volumes grows at airports worldwide. - Annex A2: Hydroprocessed Esters and Fatty Acids (HEFA SPK).

Purchasing fuel is a primary operating cost for airlines, a cost only exceeded by labor (IATA 2018). SAF will need to be cost-competitive, but although costs must be reduced, SAF does not need to mimic petroleum. A better fuel via bio-derivatives can be made and still meet international specifications (i.e., ASTM International, or ASTM). The current maximum blend ratio of SAF to conventional jet fuel which has been approved by ASTM [the American Society for Testing and oligomerization). All they have to do is ensure that the SAF meets the requirements of the ASTM D7566 synthetic fuel standard.
