From Waste to Wealth: How Brazil is Turning Pig Manure and City Trash into the 'Fuel of the Future'

Across Brazil there’s a pretty quiet revolution happening, in the pipes and pits of the country’s industrial heartlands. From hog farms down south to the trash heaps in the northeast, waste isn’t just some leftover problem anymore, it’s turning into a kind of strategic energy asset.

In Santa Catarina, a southern state, a milestone has been reached this month. For the first time, biomethane made from swine waste has been injected straight into the state’s piped gas network. What used to be a costly environmental burden for pig farmers, dealing with nitrogen rich runoff that can choke local waterways is now showing up as revenue, helping power industries and stepping in for fossil derived natural gas.

“This is the state of the art,” says a local industry representative. “We went from using biogas for carbon credits, then for electricity, and now we’re purifying it into biomethane. It’s a renewable fuel that’s chemically the same as natural gas, but 100% organic.”

The Urban Frontier: Cleaning Up the Megacities

The revolution isn’t confined to the countryside. In São Paulo, South America’s largest metropolis, the transition is hitting the streets. Volkswagen Truck & Bus recently closed a landmark deal to supply 56 biomethane-powered trucks to Loga, the company responsible for urban waste collection in the city.

The irony is poetic: the very waste collected by these trucks can be processed into the fuel that powers them. These vehicles reduce CO2 emissions by up to 90% compared to diesel, and in a city plagued by noise pollution, their quieter gas engines offer a rare respite for residents.

“The market acceptance is exceeding expectations,” says Ricardo Alouche of Volkswagen. “Our production is already committed through September. The operational savings make the choice easy for clients.”

A Billion-Dollar Race in the Northeast

While the south and southeast lead in immediate application, a high-stakes investment race is heating up in the Northeast. States like Pernambuco, Bahia, and Ceará are positioning themselves as hubs for green fuels, including biomethane, sustainable aviation fuel (SAF), and green hydrogen.

In Ceará, a R$1.4 million project led by the Industrial Technology and Quality Nucleus (NUTEC) is pushing the boundaries of science. Researchers are using microalgae and artificial intelligence to purify biogas from urban sewage and agribusiness waste into commercial-grade biomethane.

The scale of the potential is staggering. The Brazilian Biogas Association estimates that the country could produce 7 million cubic meters of biomethane per day by 2030, attracting R$348 billion in investment and creating nearly 800,000 jobs.

The Infrastructure Bottleneck

However, the path to a green future is not without hurdles. Brazil’s gas pipeline network remains concentrated in coastal regions, leaving vast swaths of the interior — where the biomass is most abundant — isolated. Thousands of landfills still vent methane into the atmosphere, wasting a resource that could be heating homes or powering factories.

For regions like Paraíba, the challenge is to move beyond being a mere supplier of raw biomass. The goal is to build a local industry of engineering, automation, and technology. Therefore, the transition won’t be built solely by large plants, but it will pass through small solutions scattered across the fields and cities.

As Brazil grapples with its climate commitments, the biomethane boom offers a rare win-win: cleaning up the environment while securing energy independence. The "fuel of the future" has arrived, and it smells like opportunity.

Brazil Unveils World's First Ethanol-Powered Gas Turbine

Brazil has presented its first locally developed gas turbine powered by ethanol, a move that places the country among a select group of nations capable of producing the entire cycle of turbine technology while leveraging its leadership in biofuels, particularly with regard to Sustainable Aviation Fuel (SAF).

President Luiz Inácio Lula da Silva attended the presentation on Monday at the Aerospace Technical Center (CTA) in São José dos Campos. The 1-megawatt (MW) turbine, developed by Aero Concepts in partnership with the Institute of Aeronautics and Space (IAE).

STRATEGIC SOVEREIGNTY

The project, dubbed UGEE1000BR, is a transportable unit integrated into a standard shipping container. Beyond civil power generation for remote areas or disaster relief, the technology has significant implications for national defense. The turbine’s core technology is also being adapted for use in drones and cruise missiles.

"Brazil is now the sixth country in the world to produce a turbine from start to finish," Lula said during the ceremony, referring to a list that includes the United States, China, Russia, France, and the United Kingdom. "And it is the first country to produce a turbine 100% powered by ethanol."

REDUCING IMPORT DEPENDENCE

The development marks a strategic push for technological sovereignty. Alexandre Roma, CEO of Aero Concepts, highlighted that the company has achieved independence in raw materials and manufacturing processes, including the acquisition of vacuum micro-fusion furnaces to handle high-temperature alloys like Inconel.

The project had faced delays since its inception in 2008 but was revitalized in 2024 with a 30-million-reais ($5.2 million) investment from the federal government.

"We need to be the masters of our own destiny," Lula added. "We produce aircraft, but we are often dependent on a single comma of technology that isn't ours. This turbine changes that."

SCALING UP

The next phase of the project involves connecting the unit to a sugarcane-to-energy plant for operational testing. Aero Concepts stated it is ready to scale production if government or private orders are placed, citing potential demand from data centers and remote energy markets.

The initiative involves collaboration with the Ministry of Science and Technology, the National Development Bank (BNDES), and the Ministry of Mines and Energy, signaling a broad government commitment to the new energy matrix.

The ‘Green Paradox’: Can Brazil Drill for Oil and Lead the Climate Revolution?

As global energy investments hit a record $3 trillion, Brazil finds itself in a unique position, balancing its status as a top-10 oil producer with one of the world's cleanest energy matrices. But as the world races toward 2050, the country faces a difficult question: should it open up the "Equatorial Margin" for oil exploration?

Brazil is often cited as a global outlier in the climate crisis. While the global average for CO₂ emissions from the energy sector stands at a staggering 76%, in Brazil, that figure is just 20%. This is not an accident of history but the result of decades of public policy, from the "Proálcool" program of the 1970s to the massive expansion of hydroelectric and wind power.

However, a new debate is surfacing in Brasília that highlights the pragmatic, and often contradictory, nature of the global energy transition. Even as the country invests heavily in Sustainable Aviation Fuel (SAF) and green hydrogen, it is also eyeing the "Equatorial Margin," a vast offshore area in the north that could hold billions of barrels of oil.

THE PRAGMATIC PATH

"The transition is a compilation of joint actions by environmentalists, economists, and governments," says Dr. Paula Meyer, an energy economics expert at the University of Brasília. "It’s not just about speed; it’s about a complex process of converting entire production chains. Oil and gas will remain essential components of our base during this maturation period."

For Yuri Schmitke, head of the Brazilian Waste Energy Association, the path forward is not about "attacking the system" of fossil fuels but about a gradual, balanced reduction. He argues that Brazil’s true strength lies in its "multiplicity of solutions", like biomass, biogas, and biomethane, which often receive less regulatory attention than solar or wind but offer 10 to 15 times more decarbonization potential.

A GLOBAL REBALANCING

While Brazil navigates its internal dilemmas, the global stage is shifting. China has consolidated its dominance in clean energy supply chains and critical minerals. Meanwhile, the United States is struggling to regain technological ground after years of subsidy cuts, and Europe’s green ambitions are being sidelined by the urgent need for military spending amid regional conflicts.

"Brazil has already done its energy transition decades ago," Schmitke points out, noting that the country's electricity matrix is already 93% renewable, a target Europe is only hoping to reach by 2050.

THE CARBON MARKET FRONTIER

The next great challenge for Brazil is the implementation of a regulated carbon market (SBCE). By aligning with international standards, Brazil aims to turn its environmental preservation and reforestation efforts into a massive financial asset, exporting carbon credits to the "global north" to offset emissions in the US, China, and Europe.

As the world’s energy investment increasingly pivots toward renewables, double the amount spent on fossil fuels, Brazil’s "eclectic" approach serves as a benchmark test for the rest of the world. Can a nation remain a global oil giant while simultaneously leading the charge toward a zero-carbon future? In the halls of power in Brasília, the answer seems to be that it must do both.

Petrobras (PETR3; PETR4) Expands Energy Transition Strategy with Critical Minerals, SAF and Biofuels Investment

Petrobras (PETR3; PETR4) has been taking pretty significant steps over the past week, to kind of lock in its role in the global energy transition. The focus is on critical minerals, sustainable fuels and fiscal compensation, all of that at once.

PARTNERSHIP FOR CRITICAL MINERALS

Petrobras and the Brazilian Development Bank, BNDES, signed a protocol of intentions to collaborate on research and innovation, for critical and strategic minerals. The whole thing is meant to tackle technological bottlenecks within the supply chains for electrification, for batteries, and for clean energy. In Brazil there are major reserves of graphite, nickel, manganese, lithium, and aluminum too, and this partnership wants to take advantage of Petrobras’ research know-how so the country can plug into higher-value global production chains.

$1.2 BILLION BIOREFINERY INVESTMENT

The state-run oil giant also approved the final investment decision (FID) for a new $1.2 billion biofuels plant at the Presidente Bernardes Refinery (RPBC) in Cubatão, São Paulo. The unit will have a production capacity of 15,000 barrels per day, focusing on Sustainable Aviation Fuel (SAF) and renewable diesel. Scheduled to begin operations in 2030, the project aligns with Brazil’s "Fuel of the Future" law and international aviation decarbonization standards (CORSIA), marking a major milestone in the company’s 2026-2030 business plan.

DIESEL SUBSIDY REIMBURSEMENT

Petrobras received 752 million reais ($130 million) as the first installment of a government economic subsidy program for diesel. This payment covers the period between March 12 and March 31, following a measure that provided a 0.32 reais per liter aid. The subsidy program, intended to stabilize domestic prices, is expected to remain in effect until the end of 2026, though the government has signaled potential periodic reviews of the policy.

MARKET CONTEXT

The moves come as global competition for critical minerals intensifies, with G7 leaders recently agreeing to reduce dependence on China. Brazilian officials view this as a "window of opportunity" to demand local industrialization and processing investments. Meanwhile, the domestic transport sector remains cautious; while overall automotive sales are rising, truck registrations fell 3.24% in April compared to last year, with industry leaders looking to credit programs and trade fairs to unlock pent-up investment.

Raízen’s Vision for SAF Could Transform Brazil into an Aviation Fuel Superpower

In the 1970s, reeling from a global oil crisis, Brazil launched Pro-Álcool, a pioneering program that turned sugarcane into a national fuel staple. Today, as the world faces a dual crisis of geopolitical instability and climate breakdown, Brazil is dusting off its energy-sovereignty playbook for a new, high-stakes arena: the skies.

Sustainable Aviation Fuel (SAF) is no longer a distant green dream; it is becoming a geopolitical and economic imperative. As airlines grapple with the volatility of jet fuel prices, recently underscored by the bankruptcy filing of US-based Spirit Airlines, and stringent new mandates from the EU and UK, the search for a scalable, low-carbon alternative has reached a fever pitch.

A Sleeping Energy Giant

"We often suffer from 'stray dog syndrome' in Brazil," says Raphaella Gomes, CEO of Raízen-Geo Biogás S.A. and one of the country's most influential voices in energy. "We talk too little about our strengths. We treat biofuels as a 'green agenda' item, but it is actually a strategic pillar for industrial development and international trade."

Gomes argues that Brazil is uniquely positioned to fill a massive global supply gap. By 2035, global demand for SAF is expected to hit 50 billion liters. While the US market is likely to be served by domestic production incentivized by protectionist policies, the European and Asian markets are looking for suppliers. Experts predict a 15-billion-liter shortfall in a decade, a gap Brazil is eager to close.

Why Brazil?

The secret lies in what Gomes calls an "integrated agro-energy chain." Brazil isn't just producing fuel; it’s producing it with a carbon intensity that is hard to beat. Brazilian sugarcane ethanol, for instance, has a carbon footprint significantly lower than its international competitors.

But the revolution goes beyond sugarcane. The state of São Paulo has seen its biomethane production skyrocket, reaching 42.7 million cubic meters in 2025—a third of the national total. This "green gas," derived from agricultural waste and urban landfills, can be converted into SAF via "power-to-liquid" pathways.

"Aviation accounts for 2.5% of global CO2 emissions," Gomes explains. "Unlike cars, you can’t easily put a heavy battery on a plane. SAF is the only viable alternative for long-haul flights."

From Necessity to Opportunity

Brazil’s energy journey has always been driven by necessity. Today, the country still imports nearly 90% of its fertilizers and a significant portion of its diesel and liquefied natural gas (LNG). Recent disruptions produced by the US-Iran War and attacks on refineries in Qatar have only highlighted this vulnerability.

However, the same agricultural prowess that makes Brazil dependent on imported fertilizers also provides the "feedstock" for the future. From corn ethanol in the Mato Grosso heartland to biomethane in the outskirts of Campinas, the raw materials for a cleaner sky are already being harvested.

As the Pro-BioQAV (Programa Nacional de Combustível Sustentável de Aviação, in english "National Sustainable Aviation Fuel Program") mandate kicks in 2027, requiring a 1% reduction in aviation emissions, Brazil is moving from intention to action. The goal is to produce 2 billion liters of SAF by 2030. In a world hungry for energy security and decarbonization, Brazil’s "green pre-salt" might just be the fuel that keeps the global economy aloft.

Volkswagen also bets on Brazilian biomethane 

Ricardo Alouche, Vice President of Sales at Volkswagen Trucks and Buses, believes Brazil’s truck market will remain resilient throughout 2026 despite high interest rates, restricted credit conditions, and broader economic uncertainties.

According to Alouche, the federal government's Move Brasil financing program has been a key factor supporting truck sales. 

Looking ahead, Volkswagen is preparing several product launches for Fenatran 2026, Brazil’s largest commercial vehicle exhibition. The company also expects the event to focus more on technology, products, and customer relationships than on discounts and sales promotions, as many buyers are already bringing forward purchasing decisions due to favorable financing conditions.

On alternative propulsion technologies, Alouche highlighted growing interest in electric trucks, biomethane-powered vehicles, and hybrid solutions. All of this is an effort by the automaker to try to find solutions for the fluctuations in the fuel market, which affect those who work in the transportation sector. However, Alouche emphasized that adoption will occur gradually due to infrastructure limitations and cost considerations. Volkswagen is currently testing biomethane trucks in urban sanitation operations and advancing development of its hybrid Meteor truck, which is undergoing advanced testing.

How Raízen (RAIZ4) Engineered Brazil’s Biggest Corporate Restructuring

Raízen, the Brazilian sugar and ethanol giant and a joint venture between Shell and Cosan, has formalized a record-breaking 64.7 billion reais ($11.5 billion) out-of-court restructuring plan. The agreement, filed with São Paulo’s 3rd Bankruptcy Court, marks the largest "recuperação extrajudicial" (corporate restructuring) in Brazil’s history, securing support from 75.4% of its creditors after months of intense negotiations.

The restructuring follows a period of severe financial strain for the company, driven by aggressive investments in second-generation ethanol and renewable energy projects that coincided with weaker-than-expected sugarcane harvests, high interest rates, and capital-intensive expansions that failed to yield immediate returns.

Step-by-Step Restructuring Framework

The finalized plan outlines a comprehensive roadmap to stabilize the company's finances and reorganize its sprawling operations:

• Debt Conversion and Refinancing: The company will convert 45% of its 64.7 billion reais debt into equity. Creditors opting for this route will receive "Units" (comprising one common and one preferred share) priced at 0.50 reais per Unit. The remaining 55% of the debt will be refinanced through new financial instruments;
• Capital Injection: Shell has committed a 3.5 billion reais ($620 million) cash infusion to bolster the company's capital structure. Aguassanta Participações, linked to the Ometto family, may contribute an additional 500 million reais;
• Asset Divestment: To streamline operations and raise immediate liquidity, Raízen sold its downstream assets in Argentina, including refining and distribution, to the Swiss-based Mercuria Energy Group for $1.42 billion;
• Governance Overhaul: The company’s board will be restructured to include seven members. Four will be appointed by supporting creditors, including the board's chair, while three will be named by the shareholders responsible for the capital injection. Shell will maintain its board presence as long as its brand licensing agreement remains in effect;
• Operational Split by 2027: Raízen plans to divide into two independent entities by the end of 2027: Raízen Energia (focusing on sugar, ethanol, and bioenergy) and Raízen Combustíveis (concentrating on fuel and lubricant distribution under the Shell brand).

Market Reaction and Outlook

Brazilian energy giant Raízen has secured a historic restructuring agreement. Now, the plan, backed by 75.4% of creditors, aims to stabilize the Shell-Cosan joint venture following heavy losses from aggressive renewable energy expansions and high interest rates.

Key components of the deal include:

• Debt-to-Equity Swap: 45% of the debt will be converted into equity, potentially giving creditors up to 80% control;
• Cash Infusion: Shell will inject 3.5 billion reais ($620 million) in new capital;
• Divestment: The company sold its Argentine downstream assets for $1.42 billion to Mercuria Energy Group;
• Strategic Split: By 2027, Raízen will split into two independent units: Raízen Energia (sugar/ethanol) and Raízen Combustíveis (fuel distribution).

Despite initial resistance from major creditors like Itaú Unibanco, the deal provides a clearer trajectory for the company’s survival in the critical agribusiness and energy transition sectors.

The negotiations were characterized by significant friction, particularly with Itaú Unibanco, which initially opposed the deal and attempted to sway other creditors before eventually signing. 

Analysts view the plan as a critical step for Raízen, which is a linchpin in Brazil's agribusiness and energy transition sectors. By converting a massive portion of its debt into equity, creditors could eventually control up to 80% of the company, fundamentally altering the historical Shell-Cosan partnership. Shell stated the move provides "greater financial stability and a clearer trajectory for the future," preserving the brand's presence in Brazil's vital fuel and aviation markets (SAF).

Macaúba Revolution: Brazil’s Answer to Sustainable Aviation Fuel (SAF)

For decades, farmers in the Brazilian Cerrado viewed the Macaúba palm (Acrocomia aculeata) as nothing more than a nuisance. Its long, razor-sharp thorns made working near it a nightmare, and it seemed to sprout everywhere without being planted. Most landowners simply cut it down to make room for cattle or soy.

But today, this "thorny pest" is being rebranded as "green gold." Some of the world’s most powerful investors are betting billions that this native palm will become the ultimate feedstock for the next generation of sustainable fuels — potentially outperforming soy, palm oil, and even fossil fuels in the race to decarbonize the planet.

THE OIL POWERHOUSE

The numbers behind the Macaúba are staggering. Researchers have discovered that the palm can produce over 4,000 liters of oil per hectare per year. To put that in perspective, soy — currently the primary source for Brazilian biodiesel — produces an average of just 400 liters per hectare. In the same space, the Macaúba yields ten times more oil.

For many specialists the Macaúba is almost like the petroleum of the future. Its oil is uniquely suited for the production of HVO (Hydrotreated Vegetable Oil) and SAF (Sustainable Aviation Fuel). Unlike conventional biodiesel, which often requires engine modifications and limited blending, HVO and SAF are chemically identical to fossil fuels. This means planes and trucks can run on them pure, without a single bolt being changed in their engines.

BEYOND FUEL: A CIRCULAR MIRACLE

The true advantage of the Macaúba lies in its "zero-waste" profile. While soy is primarily grown for its beans, almost every part of the Macaúba fruit has a commercial use:

• The Husk: Burned to generate renewable energy.
• The Pulp: Extracted for HVO and SAF production.
• The Residue: High-protein "cake" used as cattle feed.
• The Endocarp: A hard shell used to produce high-density charcoal for the steel industry.
• The Kernel: Produces a high-value oil for cosmetics and food, similar to coconut oil.

Even the tree itself offers benefits. Its tall, sparse canopy allows sunlight to reach the ground, enabling a system known as "crop-livestock integration." Farmers can plant Macaúba palms directly in their pastures, allowing cattle to graze beneath the trees while harvesting oil from above.

HEALING THE LAND

Perhaps the most compelling environmental argument for the Macaúba is its ability to thrive on degraded land. Brazil has an estimated 50 to 70 million hectares of exhausted pastureland, areas that are currently unproductive and generate near-zero income.

Because the Macaúba is a hardy native species adapted to poor soils, it can be used to reforest these areas, recovering the soil’s organic matter and reducing erosion while providing a sustainable income stream for rural communities.

THE BILLION-DOLLAR BET

The scale of the investment suggests this is more than just a passing trend. Acelen Renováveis, a subsidiary of the UAE’s sovereign wealth fund Mubadala Capital, has announced a 3 billion US dollars plan to build a massive Macaúba supply chain in Brazil.

The company has already established a nursery in Minas Gerais capable of producing 10 million seedlings per year. Their goal is to produce 1 billion liters of HVO and SAF annually by 2038, targeting the lucrative European and American markets where traceability and carbon intensity are strictly regulated.

LESSONS FROM THE PAST

The Macaúba’s rise inevitably draws comparisons to previous "miracle crops" like castor beans (mamona), which were promoted in the early 2000s but failed to reach commercial scale due to low productivity and high costs.

However, proponents argue the Macaúba is different. Unlike the castor bean programs, which were government-led, the Macaúba push is driven by global institutional capital and a real, skyrocketing international demand for aviation decarbonization.

Challenges remain, most notably the difficulty of harvesting fruit from tall, thorny palms and the five-to-six-year wait for the first harvest. But if the bet pays off, Brazil could soon be exporting high-tech fuel made from a plant that farmers once fought to eliminate.

In the Cerrado, the "praga" has become the promise.

São Paulo Set for Record Biomethane Production, Targeting 1 Million Cubic Meters Daily

After the Brazilian federal government published on May 6 the Resolution 4/2026 of the National Energy Policy Council (CNPE), which sets an annual targets for greenhouse gas (GHG) emissions, the state of São Paulo is on track to reach a record installed production capacity of 1 million cubic meters of biomethane per day by the end of 2026, enough to supply all 2.8 million residential gas connections in the state, officials said.

The volume, equivalent to replacing approximately 4,000 diesel-powered urban buses, marks a major milestone in Brazil’s energy transition. São Paulo currently hosts nine of the 19 biomethane plants operating nationwide, with another 11 units awaiting authorization.

"We are preparing to reach the record mark of approximately one million cubic meters per day by December," Marisa Barros, Undersecretary for Energy and Mining at the State Secretariat for Environment, Infrastructure, and Logistics (Semil), told an industry event last week.

DECARBONIZING LOGISTICS

The surge in biomethane — a renewable gas produced from agricultural and landfill waste — is central to São Paulo’s strategy to hit net-zero emissions by 2050. Heavy vehicles, such as trucks and buses, are primary targets for conversion to the renewable fuel, which can reduce greenhouse gas emissions by up to 99% compared to diesel.

In the city of São Paulo, the "BioSP" program is already testing biomethane-powered buses to bypass infrastructure bottlenecks currently hindering electric vehicle adoption.

CORPORATE ADOPTION

Major industries are already integrating the fuel into their operations:

• Natura: The cosmetics giant uses biomethane to power 45% of its industrial processes and 100% of its logistics fleet between its Cajamar factory and Greater São Paulo.
• Aviation Sector: Projects are underway to produce Sustainable Aviation Fuel (SAF) from biogas derived from sugarcane waste, supported by international partnerships with institutions like Sweden’s Swedfund.

REGULATORY MOMENTUM

The National Petroleum Agency (ANP) has streamlined authorization processes to align with Brazil’s "Fuel of the Future" law. "We noticed a significant increase in requests for new industrial plants, driven by recent federal and state incentives," said Marcos Werner, a superintendent at the ANP.

Beyond São Paulo, other states are also advancing:

• Santa Catarina: H2A Bioenergia recently received authorization for the country’s first biomethane plant using swine waste.
• Rio Grande do Sul: State distributor Sulgás launched the "BioHub" to connect remote producers to the existing gas grid, aiming to diversify the state’s energy portfolio and reduce reliance on external sources like Bolivia or offshore pre-salt gas.

CIRCULAR ECONOMY

The expansion of biomethane is being framed as an economic opportunity for small farmers and agribusinesses to monetize organic waste. State environmental agency Cetesb has modernized its licensing procedures, reducing approval times to as little as 60 days to accelerate the transition.

"Biomethane is a strategic pillar in decarbonization," said Allan Cellim da Silva of Cetesb. "It integrates the biofuel into the circular economy while ensuring a secure and agile transition for the industry."
