Used cooking oil to produce sustainable aviation fuel: IndianOil
PTI
New Delhi, Aug 17 (PTI) Cooking oil is often discarded after being used for frying at home or in restaurants. However, a refinery of IndianOil has now won a certification to use the same oil to produce sustainable aviation fuel (SAF), the company chairman Arvinder Singh Sahney said.
SAF is an alternative fuel made from non-petroleum feedstocks that reduces emissions from air transportation. It can be blended up to 50 per cent in conventional aviation turbine fuel (ATF or jet fuel), depending on availability. India has mandated 1 per cent SAF blending in jet fuel sold to international airlines from 2027.
IndianOil's Panipat refinery in Haryana has won the International Civil Aviation Organization's (ICAO) ISCC CORSIA certification (International Sustainability and Carbon Certification – ISCC – developed under the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) to produce SAF from used cooking oil, he said.
'We are the only company in the country to get this certification," he said.
'The refinery will start producing some 35,000 tonnes per annum of SAF from the end of the calendar year." The production will be enough to meet the mandated 1 per cent blending requirement for the country in 2027, he added.
Explaining the process, agencies will collect used cooking oil from large users, such as hotel chains, restaurants, and snacks and sweets producing companies like Haldiram, and supply it to Panipat refinery.
Panipat refinery will use this oil to produce SAF, he said.
'There is a large amount of such oil available in the country. The only challenge is collection. While it is easy to collect from large hotel chains, a solution needs to be found for collection from small users, including households," he said.
Parallely, the company has also set up a Rs 5,000 crore plant at its Koyali refinery in Gujarat to produce Butyl Acrylate (BA), which is used in making paints.
The 1,50,000 tonnes per annum Butyl Acrylate plant, only second in India after BPCL's unit at Kochi refinery, will help end 3,20,000 tonnes of annual paint feedstock that the country currently imports, Sahney noted.
State-owned Indian Oil Corporation (IOC) has been at the forefront of innovations, particularly in the areas of green energy, sustainable solutions, and technological advancements. The firm is working on renewable energy sources, like 2G ethanol, fuel cells, bio-diesel, and energy storage devices.
'The paint industry is growing at a CAGR of 13-14 per cent, and the bulk of the raw material they use is imported. In July, we commissioned the BA unit at Koyali refinery, which will eliminate the need to import, saving foreign exchange for the country," he said.
Together with the Kochi plant, the new unit can substitute as much as 80-90 per cent of imports, he said.
On green hydrogen, Sahney said the company awarded a tender for the country's largest green hydrogen plant to L&T.
'The 10,000 tonnes a year green hydrogen unit at the Panipat refinery will be ready in 27 months," he said.
Green hydrogen, produced from splitting water using renewable energy, is a clean energy source that only emits water vapour and leaves no residue in the air, unlike coal and oil. It can be used in industries and automobiles as fuel, but the prohibitive production cost has been a stumbling block.
India has relatively cheaper renewable energy (electricity produced from sunlight and wind), which has helped keep green hydrogen production cost at less than USD 4 per kg, the chairman said, adding that IndianOil will use the fuel in its Panipat refinery.
Refineries, currently, use grey hydrogen – hydrogen produced from fossil fuels – in hydrocracking units to produce fuels like petrol and jet fuels.
'IndianOil remains agile and nimble in product innovation and meeting fast-changing energy dynamics," Sahney said. 'A lot of other innovations are in the works, which will be unveiled when they mature." Explaining the SAF certification process, he said, 'SAF produced at IOC's Panipat refinery has undergone rigorous assessment for lifecycle carbon emissions and traceability, creating a clear pathway for Indian airlines to integrate certified SAF into their operations".
Certifications like ISCC CORSIA ensure the fuel meets environmental and social standards.
The certification also sets a benchmark for other domestic refiners and industry players to scale up SAF production, in line with the government's vision of achieving net-zero emissions by 2070.
With this recognition, IOC has once again reaffirmed its role as a trailblazer in India's energy transition, bringing India closer to a greener and cleaner aviation future.
India plans to mandate blending of SAF with conventional ATF in a staged manner. One per cent SAF blending in ATF sold to all international flights is to start from 2017 and increase to 2 per cent in the following year.
SpiceJet had flown a test flight, using a blend of 75 per cent regular ATF and 25 per cent biofuel in August 2018. Subsequently, IndiGo did a demonstration flight using a 10 per cent SAF blend on an international flight in February 2022.
While CORSIA is a key part of the International Civil Aviation Organization's (ICAO) strategy to achieve carbon-neutral growth for international flights going ahead, Cotecna is a leading provider of testing, inspection and certification services. PTI ANZ ANZ BAL BAL

Trump aide slams India for buying Russian oil, says Delhi needs to act like strategic partner of US
London, Aug 18 (PTI) President Donald Trump's trade adviser Peter Navarro has slammed India for what he dubbed as an "opportunistic" purchase of crude oil from Russia and said New Delhi needs to act like a strategic partner of the US. In a column for 'The Financial Times' on Monday, the White House counsellor for trade and manufacturing accused India of acting as a global clearinghouse for Russian oil by converting embargoed crude into high-value exports. "India's dependence on Russian crude is opportunistic and deeply corrosive of the world's efforts to isolate Putin's war economy,' writes Navarro. 'In effect, India acts as a global clearinghouse for Russian oil, converting embargoed crude into high-value exports while giving Moscow the dollars it needs,' he claims. Opening with the so-called 'mathematics' of Russia-India ties, Navarro claims American consumers buy Indian goods, and then those dollars are used to buy discounted Russian crude oil. "That Russian crude is refined and resold around the world by Indian profiteers in league with silent Russian partners — while Russia pockets hard currency to fund its war machine in Ukraine. As Russia continues to hammer Ukraine, helped by India's financial support, American (and European) taxpayers are then forced to spend tens of billions more to help Ukraine's defence. Meanwhile, India keeps slamming the door on American exports through high tariffs and trade barriers,' he writes. In his Op-Ed, Navarro goes on to attack India for imposing what he claims are some of the highest average tariffs in the world, along with a dense web of non-tariff barriers that 'punish' American workers and businesses. 'As a result, the US runs a massive trade deficit with India, nearing USD 50 billion annually. And here's the kicker: India is using those US trade dollars to buy Russian oil,' he states. According to the White House adviser, the surge in India's crude imports since February 2022 has not been driven by domestic oil consumption needs but by 'profiteering' of the country's 'Big Oil lobby'. 'Refining companies have turned India into a massive refining hub for discounted Russian crude. The refiners buy oil at a steep discount, process it, and then export refined fuels to Europe, Africa, and Asia — all the while shielding India from sanctions scrutiny under the pretence of neutrality,' he writes. While defending Trump's recent executive order hitting Delhi with exorbitant trade tariffs, his aide goes on to allege that India keeps slamming the door on American exports through barriers. Navarro claims that while Delhi has increasingly turned to the US, France and Israel to meet its defence needs, those deals often come with strings attached. He concludes: 'The Trump administration is confronting it. A recent executive order issued by the President will impose a 25 per cent national security tariff on Indian goods to address the threat posed by India's continued importation of Russian oil. This new tariff is in addition to the 25 per cent reciprocal tariff already in place. "This two-pronged policy will hit India where it hurts — its access to US markets — even as it seeks to cut off the financial lifeline it has extended to Russia's war effort. If India wants to be treated as a strategic partner of the US, it needs to start acting like one.' Trump has imposed tariffs totalling 50 per cent on India, including 25 per cent for Delhi's purchases of Russian oil that will come into effect from August 27. India, responding to the tariffs, said that the targeting of India is unjustified and unreasonable.

ACs to get cheaper? Here's how much costs can reduce if GST reforms come into force
modeThe Finance Ministry on August 15 (India's 79th Independence Day), said that it has proposed reforms to the country's goods and services tax (GST) regime, with aim to simplify the process and rationalise rates. Later, on August 17, Prime Minister Narendra Modi added that the Centre has circulated the draft GST reforms among states and sought their cooperation to implement the proposal before Diwali. Electronic makers think so, they expect that the government will mark down electronics from the current 28 per cent GST bracket to the 18 per cent slab, thus allowing for reduction in costs by ₹ 1,500-2,500 depending on the AC models, PTI reported. The cost cuts take into account the proposed GST revisions and repo rate impact, it added. Apart from ACs, your televisions could also come cheaper, when applying the same principle of lower GST slab. At present, TV screens over 32 inches are taxed at 28 per cent — this could come down to 18 per cent. B Thiagarajan, MD of Blue Star feels the GST reforms are a 'great move', adding that the price benefit to the customer on the final pricing would be around 10 per cent, PTI reported. Manish Sharma, Chairman of Panasonic Life Solutions India said it would be 'phenomenal' if electronics and appliances are brought into the 18 per cent bracket, as 'there will be a straight 6 to 7 per cent odd price reduction in the market' that will 'result in reduction of ₹ 1,500 to ₹ 2,500', depending on the cost of the models. Among the sectors likely to see costs reduction due to the proposed GST reforms include everyday essentials such as groceries (food, fruits, vegetables), medicines, electronics (including ACs, TVs, fridges, washing machines), agricultural equipment, bicycles, insurance and education services. In groceries, items such as condensed milk, dried fruits, frozen vegetables, sausages, pasta, jams, namkeens including bhujiya, tooth powder, feeding bottles, carpets, umbrellas, bicycles, utensils, furniture, pencils, handbags made of jute or cotton, and footwear under ₹ 1,000 are currently taxed at 12 per cent GST, but will be brought under the 5 per cent umbrella, allowing for cost reductions. As of August 18, the effective GST rate slabs in India are 5 per cent, 12 per cent, 18 per cent, and 28 per cent, on most goods and services, except commodities such as gold and silver. The reforms propose new tax slabs of: 5 per cent (collapsing the 12 per cent slab into it), 18 per cent (collapsing the 28 percent slab into it), and 40 per cent for select 'sin' category goods such as tobacco and alcohol products. Notably, since GST is a consumption-oriented tax, PTI reported most experts agreeing that it is the final consumers who will ultimately benefit from these reforms, as lower GST means lower final cost.
