Used Cooking Oil as a Drop-In Replacement for Fuel Oil in Buildings: Lifecycle Renewables’ Truburn Offers Big Emissions Reduction, a Beneficial Circular Economy, and UCO Market Projections

     Lifecycle Renewables is offering a used cooking oil (UCO) drop-in replacement for fuel oil in the New York City area that claims a 93% reduction in greenhouse gas emissions. The city’s ‘Local Law 97’ demands replacement of the dirtiest fuel oil with an upcoming ban on this No. 4 oil expected to take effect soon. The city and the whole Northeast region have held onto the use of expensive, dirty, and carbon-emitting fuel oil instead of welcoming natural gas, which could have become a more durable and widespread replacement, cutting costs, pollution, and emissions. More than 80 percent of all heating oil in the U.S. is used in the Northeast, where more than 30 percent of all homes and businesses use it as their primary fuel. My question: Is there really enough used cooking oil locally available to replace all the fuel oil used in NYC? I don’t know the answer yet, but I doubt it.

     Lifecycle Renewables’ heating oil, known as Truburn, offers a 93% reduction in emissions compared to fossil fuels (likely No.4 fuel oil, since natural gas is much less emitting than that fuel oil) and 74% directly counts toward Local Law 97 compliance. The EPA tags biodiesel from UCO as 86% less emitting than diesel. 




     Apparently, Truburn is new to NYC but has been used for over a decade at some college campuses and in some cities in the Northeast. Lifecycle touts Truburn as the leading fuel oil for Local Law 97 compliance. Truburn is primarily soy oil that has been treated to remove impurities that might make combustion challenging. It is entirely a drop-in replacement aside from “a simple fine-tuning of the burner.” According to a 2024 post, Lifecycle delivers millions of gallons of Truburn from Maine to Philadelphia. It touts its Truburn as locally derived and locally delivered. It is stable and non-degradable and without the fumes of fuel oil, although they say there is “a faint, familiar fried food smell.”

     UCO is waste oil. Thus, it also has the feature of reducing waste that would otherwise be in need of disposal. It is a circular economy solution. UCO may also be blended with traditional fuel oil for less emissions reduction but more ease of processing, and is required in Connecticut. UCO is collected for free from local restaurants, which helps them dispose of it cheaply, and companies such as Lifecycle Renewables filter and process it into a usable drop-in fuel replacement. The company says that Truburn costs are similar to heating oil costs. Of course, natural gas is still far cheaper.

     According to a November 2016 Restaurant & Retail Facility Business article, 250 million gallons of used cooking oil are produced per year by U.S. restaurants. They also note that all restaurants are legally required to recycle their cooking oil, also known as yellow grease. I wrote recently about the problem of “fatbergs,” huge clogs of grease and solid material in sewer systems. Recycling oil keeps more grease out of our sewer systems, where it can be very expensive to remedy. The oil may be used in animal feed, cosmetics, or converted to biodiesel. I’m not sure how Truburn differs from biodiesel. The use of automated oil management systems in large restaurants can aid UCO recycling, as shown below.




     These systems also eliminate the discarded packaging plastic (35lb plastic oil jugs are common) and cardboard that would be used to haul the oil. In these systems, it can be delivered from one large tank to another. This means less waste in landfills. It also helps to keep employees from dumping used oil down drains. The tanks for its used oil are outside, where they can be easily transferred to a truck used by a company such as Lifecycle.

 




The History of Vegetable Oil as a Fuel

     This is mostly a summary of a Lifecycle Renewables blog post. They note that olive, castor, and grapeseed oil lamps were used in ancient times for light and a little bit of heat. Whale oil replaced vegetable oil in the 1700s, but the discovery of more petroleum in the ground in the late 1800s ended up saving the whales, although the high cost of whale oil after populations dwindled led to oil producers mixing corn alcohol with turpentine to create camphine as a light fuel.

In the early 1900s, pioneering engineer Rudolph Diesel tested the earliest versions of his engine to see how they ran on various kinds of vegetable oil, reasoning that the durable workhorse motors would be easier to market in far-flung locations that otherwise would have to rely on imported petroleum-derived fuel.”

     He reasoned that places could grow their own seed oils for fuel.

     During the 1970s energy crisis many countries experimented with alternative diesel engine fuels, including vegetable oils. It was also discovered that vegetable oil burns much cleaner than diesel, with less pollution and carbon emissions. Biodiesel began to be produced in quantity in 1987 in Austria. In the modern U.S., we power our gasoline transport with 10% or more added ethanol derived from plants. Thus, 10% or more of our transport is via biofuels. Nowadays. UCO can be incorporated into a functional circular economy where waste is reused as a valuable commodity, emissions are reduced significantly, and less grease gets into sewer systems. However, there is no cost reduction in the Northeast. Traditional fuel oil is already much more costly than natural gas, propane, and electric heat. That means the region won’t incur costs for switching from one expensive fuel to another. In other regions of the country, the costs to switch from natural gas, propane, or electric heat to UCO or biodiesel would be prohibitive. That means that only this region would not take an economic hit for switching. That also suggests that the region can import UCO from other parts of the country if needed.  

 

UCO Market Projections

     According to Fortune Business Insights:

The global used cooking oil market size was valued at USD 6.90 billion in 2024. The market is projected to grow from USD 7.43 billion in 2025 to USD 12.85 billion by 2032, exhibiting a CAGR of 8.13% during the forecast period. The used cooking oil market is poised for substantial growth in the coming years, driven by sustainability initiatives, technological advancements, and increasing demand for renewable energy sources. North America dominated the used cooking oil market with a market share of 43.62% in 2024.”




     They believe the global UCO market will nearly double over the next seven years. They note that:

North America dominated the used cooking oil market with a 43.62% share in 2024, driven by high biodiesel production capacity, government recycling incentives, and strong infrastructure for UCO collection.”



     The North American market is expected to grow to $5 billion in 2032 from $3 billion today. They also project that somewhere around 20% of the source of the UCO will be from households. I find that a bit hard to believe since it seems hard to believe that households use that much cooking oil, and the time and logistics of individually collecting, storing, and transferring these presumably low volumes of product seem like they would be difficult to monetize. 




     They list regulatory challenges as a market restraint:

The regulatory landscape surrounding the collection, transportation, and processing of used cooking oil can be complex and vary widely by region. Stricter regulations may impose additional compliance costs on businesses involved in UCO recycling, which can deter participation in the market. Moreover, inconsistent regulations across different jurisdictions can create barriers for companies looking to operate on a larger scale.”

     They stress that enhanced collection infrastructure will strengthen the market and lead to economic growth. Efficiencies can be gained by optimizing collection routes and schedules.

     They also cite as a market challenge some issues in UCO processing, including fatty acids and water mixed in with the oil:

The presence of impurities such as free fatty acids and water in used cooking oil can complicate processing and refinement. These impurities must be removed before transesterification, which is essential for producing high-quality biodiesel. High levels of impurities can lead to poor biodiesel yields and limit the utilization of UCO in applications, such as animal feed, due to safety concerns.”

     UCO can also be processed into other products, including better quality biodiesel fuels, and ozone-treated oil, which is used in skin care and has other healthcare functions relying on its antimicrobial, antifungal, and anti-inflammatory properties. It can also be used in environmental remediation, particularly of diesel spills.

Along with the biodiesel, the UCO can produce ozone-treated oil with a higher calorific value and lower ignition point. This oil is also used as a fermentation media component that further acts as a carbon source for microorganisms. The formation of beneficial by-products of certain components can be put to further use, which drives the segment's growth.

 

UCO Imports from China: Trump Administration Threatens to Stop Them

     According to Bloomberg:

Having hit a record 1.27 million tons — worth $1.2 billion — in 2024, Chinese sales of processed edible oils to the US, mainly UCO, have plunged this year after Beijing scrapped tax relief on exports. Over the first seven months, sales were 387,000 tons versus 684,000 tons in the same period last year, according to the US Department of Agriculture.”

     It also notes that the U.S. was China’s largest UCO destination last year, totaling 43% of its UCO exports. It looks like that number has been basically cut in half. These imports are mainly used for biodiesel feedstocks. Green incentives caused U.S. UCO imports to rise dramatically in 2023, and presumably, the fall of those incentives under Trump would lead to fewer imports. Imports of cheap UCO into Europe caused local UCO prices to drop so that local producers could not profit. The U.S. has also argued that it could become a problem here as well, although it appears that the dropping of the export tax relief in China is making U.S. and E.U. UCO more competitive again. The following graph shows 2024 data for UCO imports from China, which were at a record high and have since dropped to half of what they were then. This is compared to the amount of soybeans we exported to China in 2024, which is now at zero. 




     Trump recently said he might stop trade in cooking oil with China, but that would not likely affect the biodiesel market that much, especially compared to the amount of soybeans we used to export to China which went from large amounts to zero since they refuse to buy from the U.S. and have since found other sources, mainly from Brazil and Argentina, due to tariffs.

     China is the world's largest buyer of soybeans, a massive portion of which is crushed and used to feed its massive livestock of pigs. It is entirely possible that the U.S. has permanently lost some or all of that huge market share. It is also likely that soybean farmers will need a bailout in the billions as they did during the first Trump administration China tariffs.
