Raízen (RAIZ4) Confronts R$65bn Debt Mountain in One of Brazil’s Biggest Energy Restructurings

Raízen, one of Brazil's largest energy companies, and a Shell and Cosan joint venture, has submitted an extrajudicial recovery application to renegotiate its R$65 billion debt obligations. 

The company which leads the worldwide biofuel market faces what an expert called a "perfect storm" because high interest rates and increased competition and the market refuses to pay extra costs for its eco-friendly products. The restructuring process represents one of the most extensive corporate restructurings in Brazilian history because it ranks after the Odebrecht (now known as Novonor) case.

Marcelo Gasparino who worked as a board member for Petrobras and served as Vale's board vice-president called the action a "courageous decision." He explained that "The approval process for this radical measure exists challenges because people need to understand that they must break eggs to create an omelet.

Raízen experienced its current problems because it pursued aggressive expansion which required debt financing during a time when interest rates were low, at 2%, in 2020, and now interest rates in Brazil are at 15% — or many economists, one of the reasons interest rates are so high is the irresponsible way the Bolsonaro government lowered interest rates in 2020. Critics point out that the measure, taken with the aim of stimulating the economy during the pandemic, was late or excessive, contributing to inflation and currency devaluation. 

At this time, Raízen made substantial investments in second-generation (E2G) ethanol which operates as a cleaner biofuel but the market has taken time to accept it. At the same time, Brazil witnessed the emergence of lower-priced corn-based ethanol products which has established strong competition to Raízen, that produces ethanol from sugarcane.

Another major change at Raízen, that now is seen as a strategic mistake, was when the company, in 2019, entered the retail sector through a partnership with the Mexican group FEMSA, bringing the convenience store chain Oxxo to Brazil. Analysts viewed the move as a distraction because it fell outside the company’s core energy business.

The venture required heavy capital investment to open hundreds of stores, but returns fell short of expectations. After searching for potential buyers for its stake, Raízen’s leadership decided to exit the business. Continuous cash burn led the joint venture to end in 2025.

Following the split, FEMSA resumed control of Oxxo’s Brazilian operations, while Raízen retained management of more than 1,300 Shell Select and Shell Café convenience stores. The Brazilian Oxxo operation never reached break-even, becoming a factor that worsened Raízen’s current financial crisis.

Gasparino also explained the situation now: the restructuring plan which has already been approved by creditors who control 47% of the debt provides multiple solutions which include non-core asset sales and debt-to-equity conversions and new capital funding from Shell and Cosan which are the parent companies.

The company has made a statement about its operations which will remain unchanged but minority shareholders will suffer the most from the upcoming crisis. According to Flávio Conde, analyst of Levante Investimentos,  now creditors are goingo to take control of all business value during a high-debt restructuring because they hold priority over shareholders.

Although the situation is very concerning, the company still maintains a strong position in its core fuel distribution operations, and management has taken steps in recent months to secure its future. Gasparino, for example, explained the situation by saying: “I see light at the end of the tunnel because the work being done now will create better results for everyone involved than what exists today.”

Now, the expectation is for deleveraging through an out-of-court restructuring process, aimed at improving margins in the distribution business, but with shares under heavy pressure and amid strong market skepticism.

Brazil Researchers Develop Low-Cost Catalyst to Boost Ethanol-to-Hydrogen Production

Researchers in Brazil have developed an advanced catalyst that significantly improves the efficiency and stability of ethanol-to-hydrogen conversion, offering a potential pathway to lower-cost, low-carbon hydrogen production, according to Agência Fapesp.

The study, led by Fabio Coral Fonseca of the Institute for Energy and Nuclear Research (Ipen) and published in the International Journal of Hydrogen Energy, demonstrates that fine control over the processing of perovskite-type ceramic materials can enhance hydrogen yields while eliminating the need for expensive noble metals.

Hydrogen is widely viewed as a key component of the global energy transition, particularly when produced from renewable sources. In Brazil, abundant ethanol derived from biomass presents a strategic opportunity for hydrogen generation through ethanol steam reforming (ESR), a high-temperature process in which ethanol reacts with steam to produce hydrogen and carbon dioxide.

The research focuses on improving catalysts used in ESR. Instead of applying nickel to the surface of ceramic materials through conventional impregnation methods, the team incorporated nickel directly into the perovskite crystal structure during synthesis. Under controlled conditions, the metal “exsolves,” forming highly stable nickel nanoparticles firmly anchored to the surface.

This approach enhances catalytic stability, reduces carbon deposition and prevents particle agglomeration at high temperatures, common issues that degrade conventional catalysts.

A key finding of the study is that calcination temperature plays a decisive role in performance. Catalysts calcined at 650°C delivered the best results, achieving 100% ethanol conversion, producing more than four moles of hydrogen per mole of ethanol, and maintaining stable operation for up to 85 hours with minimal coke formation. Higher calcination temperatures reduced surface area, limited nickel exsolution and weakened performance.

Fonseca emphasized that manufacturing conditions are as important as material composition. “A relatively simple adjustment in processing completely changes performance,” he noted.

Beyond ethanol reforming, the team is also exploring direct ethanol fuel cells as an alternative route for energy conversion. Their broader research into metallic exsolution in perovskites includes prior collaboration with U.S. institutions supported by the São Paulo Research Foundation and the National Science Foundation.

The scientists are now advancing toward highly controlled epitaxial thin films to study catalytic behavior at the atomic scale, using advanced characterization tools at Sirius, Brazil’s synchrotron light source.

By demonstrating that abundant, low-cost metals such as nickel can achieve high catalytic performance when properly engineered, the research outlines a promising route to reduce reliance on noble metals and strengthen sustainable hydrogen production, particularly in Brazil, where ethanol infrastructure is already well established.

Corn Ethanol in Brazil: Sustainable Biofuels Driving Food, Feed, and Fuel Production

Since 2017, the corn ethanol industry has gone through rapid growth in Brazil, establishing itself as the delicate foundation of the country's bioeconomy. Representing 98% of the companies producing ethanol from corn in Brazil, the Brazilian Corn Ethanol Association (UNEM) has been supporting the cause of environmentally sustainable fuel production and at the same time markets for food and feed.

Brazil currently has 21 ethanol plants utilizing corn, with half devoted only to corn ethanol and the other half flex plants that convert ethanol from sugarcane as well. Another 22 plants have now been planned or are under construction and shall raise production from 2.2 billion gallons presently to about 3.5 billion gallons in the coming years.

Those plants frequently employ renewable power sources, such as eucalyptus wood chips, hence lessening carbon footprints. Brazil plans also to sell carbon credits, thereby rendering the price of its ethanol lower worldwide, particularly for market areas such as Europe and California.

Now, Brazilian ethanol may gain stronger competition in the international platform. Overall, the establishment of the corn ethanol industry in Brazil has very steady growth, thus adding value to the domestic corn and its consequent production as a source of renewable fuels.

A Decade of Growth: The Period from Inception to Growth

Although still a young industry, Brazilian corn ethanol development has been quite impressive. Productivity has increased by 87% during this century, and the cultivated area in corn has also expanded by about 70%. Such intense evolution has been the result of modern biotechnology, new agricultural practices, and the introduction of corn ethanol production technologies from the USA.

This industry is not only intensifying crop production but is also enhancing land-use efficiency. Unique to Brazil is a double cropping system wherein two crops can be harvested in one year on the same land. For instance, soybean in summer and corn in winter, allowing livestock to graze in between. In some areas, corn is planted also as a third crop to increase productivity without any deforestation.

Corn Ethanol: Food, Feed, and Fuel

A common concern among international audiences is the so-called “food versus fuel” debate. In Brazil, this conflict is largely mitigated through sustainable production systems. Corn ethanol production generates multiple outputs:

• Ethanol fuel: 440 liters per ton of corn
• DDGS (Distillers Dried Grains with Solubles): 212 kg per ton of corn, a highly nutritious animal feed
• Corn oil: 19 kg per ton of corn
• Excess electricity: Supplied back to the grid

By using renewable sources like wood chips and even bamboo for steam production, Brazilian corn ethanol plants create a circular, environmentally sustainable system that provides fuel, food, and feed.

Expanding Production and Global Exports

Currently, Brazil operates 24 corn ethanol plants, with another 16 under construction and an additional 16 planned. Production is spreading geographically, from the central west region to the northeast, south, and north of Brazil, while also incorporating alternative crops such as sorghum and wheat for ethanol production.

The DDGS export market is growing rapidly, especially in Asia. In just four years, exports rose from $1 million to nearly $190 million. China alone has shown interest in purchasing 5 million tons of DDGS, highlighting Brazil's potential to become a global leader in renewable feed and biofuels.

Flex-Fuel Technology and Sustainability

Brazilian vehicles, 77% of which are flex-fuel, can run on either ethanol or gasoline. This flexibility reduces greenhouse gas emissions and positions Brazil as a global leader in sustainable mobility. Moreover, ethanol-fed DDGS allows livestock to be produced more efficiently, reducing the carbon footprint per animal while meeting international food demands.

Looking Ahead: Innovation and Carbon Reduction

The future of Brazilian corn ethanol includes:

• Sustainable aviation fuels to reduce emissions in the aviation sector
• Maritime biofuels for shipping industries
• Bioenergy with carbon capture and storage (BECCS): The first plant will become carbon-negative by capturing CO₂ from ethanol production and storing it underground

With the government increasing ethanol content in gasoline to 30% and the upcoming COP 30 in Brazil, the industry is well-positioned to accelerate renewable energy adoption while supporting the food-plus-fuel model, simultaneously producing fuel, feed, and food sustainably.

Brazil’s corn ethanol industry demonstrates that biofuel production can coexist with agricultural growth, environmental sustainability, and global trade expansion. With increasing domestic production, international exports, and ongoing technological innovation, Brazilian corn ethanol is setting a benchmark for the world in sustainable bioenergy solutions.
