Summary of Key Points
Once widely despised as a byproduct of the food industry, gutter oil has transformed into a highly sought-after commodity. China has seen both an increase in exports and prices (1.77 million tons exported in the first half of this year, a 40% year-on-year increase, with prices up by 8%), with orders extending all the way to 2027. In the United States, the demand for gutter oil has surged due to biofuel policies, leading to a shortage of domestic supplies. As a result, not only is there rampant imports from China, but there have also been incidents of cross-state theft of gutter oil. Europe, on the other hand, is purchasing large quantities of gutter oil to be processed into Sustainable Aviation Fuel (SAF) for its aviation sector's carbon reduction goals. Behind this transformation lies a global shift in policy priorities, which has turned gutter oil from a hazardous waste into a valuable green resource.
Detailed Analysis
1. Policy Drivers: Why Are Europe and the US Suddenly Competing for Gutter Oil?
The increasing value of gutter oil is primarily driven by mandatory requirements for the use of biofuels:
- United States: The demand for biodiesel is fueled by "green credits." In March this year, the U.S. raised its biofuel blending targets for 2026-2027 (aiming to achieve 26.8 billion RINs, or "green credits"). Refineries must produce or blend enough biofuels to earn these credits; otherwise, they have to purchase them at a cost. The price of credits has risen by 80% this year, prompting refineries to increase biodiesel production. However, domestic soybean and animal oils are insufficient, making gutter oil one of the cheapest alternatives.
- Europe: The EU has mandated that at least 2% of aviation fuel must be SAF by 2025, rising to 6% by 2030 and 70% by 2050. SAF can reduce carbon emissions by more than 80% and can be mixed with regular jet fuel in a 1:1 ratio, leading to intense purchases by European airlines. For example, KLM Royal Dutch Airlines has been using gutter oil for flights since 2011, and Europe's current consumption of SAF exceeds that of the United States.
2. China's Role in the Export Boom
China's surge in gutter oil exports is not accidental:
- Abundant Capacity: China began regulating gutter oil recycling a decade ago to prevent it from returning to the food supply chain and has developed a mature processing system. For instance, prices for gutter oil in Jiangsu have increased from 7,000 yuan per ton to 7,800 yuan within half a year, with orders extending to 2027. Shandong-based companies have seen their export prices rise by 30%, and export volumes have increased from 6,300 tons to 16,000 tons.
- Policy Support: In January this year, China assigned a separate tax code for "bioaviation kerosene," freeing up export quotas for traditional refined fuels. As a result, Shandong's biofuel exports exceeded 2 billion yuan in the first half of the year, with no concerns about sales.
- Cost Advantages: China has an efficient gutter oil recycling system, low raw material costs, and advanced processing technology, making its products cheaper than those produced domestically in Europe and the U.S.
3. The US Situation: The Chaos Behind Gutter Oil Theft
Gutter oil theft in the US is not a joke; it reflects a severe shortage of supplies:
- Rising Prices: Restaurants that previously had to pay to dispose of gutter oil can now sell it for tens of thousands of dollars per ton (with even higher prices in the U.S.). Theft groups steal waste oil from storage tanks at night and sell it to recyclers, with some cases involving millions of dollars.
- Domestic Shortages: U.S. biodiesel production reached a record high in June this year, but domestic supplies (soybean and animal oils) cannot keep up with demand. For example, China exported 74,500 tons of gutter oil to the US in May, a 134% increase from the same period last year. One U.S. company even placed an order for 280,000 tons of Chinese-made gutter oil at once.
4. The Transformation of Gutter Oil: From Hazardous Waste to Green Resource
Gutter oil's new role as a biofuel source includes:
- Biodiesel: Processed gutter oil can be used as biodiesel, replacing traditional diesel in trucks, generators, and other applications, with significant carbon reduction benefits. Companies like Valero Energy in the U.S. use Chinese-made biodiesel.
- **Sustainable Aviation Fuel (SAF): Advanced technologies have enabled the conversion of gutter oil into a fuel similar to jet fuel that can be used directly in aircraft. Chinese companies such as Sinopec and Shandong Sanju are involved in SAF projects, earning high prices from European buyers.
- Environmental Benefits: Using gutter oil as a fuel represents a waste-to-value transformation with nearly zero carbon emissions, aligning perfectly with global carbon reduction efforts.
5. Future Prospects: How Long Will This Trend Continue?
In the short term, policy-driven demand is expected to persist:
- The U.S. biofuel targets will continue to rise by 2027, and Europe's requirement for SAF will increase annually, leading to growing global demand for gutter oil.
- China's production capacity is still expanding (with over 40 SAF projects under construction), maintaining its export advantage.
However, potential risks exist, such as the possibility of trade barriers (e.g., tariffs on Chinese biofuels) or technological advancements that may replace gutter oil with other alternatives. Nevertheless, the "golden age" for gutter oil is likely to continue for the next few years.
In One Sentence
The rise of gutter oil is a result of global carbon reduction policies and China's industrial upgrading. What was once considered waste has become a valuable green resource, reflecting a global competition driven by policy, demand, and production capacity.
