'''Rubens Ometto Silveira Mello''' (born October 5, 1950) is a Brazilian industrialist and the chairman of [[Cosan]], a diversified energy and logistics conglomerate, and [[Raízen]], one of the world's largest biofuel producers formed through a joint venture with [[Shell plc|Shell]]. Often called Brazil's first "ethanol billionaire," he transformed a debt-ridden family sugarcane business into a global leader in renewable fuels through aggressive acquisitions and the pioneering decision to take a sugar mill public.

Born into one of Brazil's great sugarcane dynasties, Ometto fought his own family in a decade-long legal battle to gain control of the business that would become Cosan. His combative approach earned him the nickname "the tractor" in Brazilian business circles—a reference to both his determination and the agricultural roots of his empire.

Under his leadership, Cosan has grown from regional sugar producer to a diversified conglomerate with interests spanning ethanol production, fuel distribution, natural gas, lubricants, railroads, and ports. The 2011 joint venture with Shell created Raízen, combining Cosan's expertise in sugarcane ethanol with Shell's global fuel distribution network.

== Early life ==

Rubens Ometto Silveira Mello was born on October 5, 1950, in Piracicaba, a city in the interior of São Paulo state that serves as the heartland of Brazil's sugarcane industry. His family heritage connected him to one of Brazil's most prominent ethanol dynasties.

The Ometto surname, inherited from his mother's side, was synonymous with sugarcane in Brazil. The family had founded Usina da Barra in 1943, one of the country's largest sugar and ethanol mills. Growing up on the family farm in close proximity to sugarcane plantations instilled in him a deep appreciation for agriculture and the biofuels industry.

His father was a successful businessman, though the family business was divided among seven siblings, creating the foundation for conflicts over power and management that would shape Rubens's early career. His mother held only 11% of the family patrimony, which limited Rubens's initial inheritance and motivated his later legal battles.

He had two brothers, including Celso Mello Filho, who would tragically die in a plane crash in 2021.

== Education ==

Ometto pursued higher education at the University of São Paulo, one of Brazil's most prestigious institutions, where he studied engineering. This technical background would prove valuable in understanding the industrial processes of sugar and ethanol production.

After completing his degree, he interned at Unibanco, gaining exposure to Brazilian finance and capital markets. This banking experience would later inform his pioneering decision to take Cosan public.

Following his internship, Ometto secured a position as financial director at Votorantim Group, one of Brazil's largest industrial conglomerates, through the mentorship of Antônio Ermírio de Moraes, one of the country's most respected industrialists. At Votorantim, he became the youngest financial director in the group's history, demonstrating his capabilities before returning to the family sugarcane business.

== Career ==

=== Family conflict and control of Cosan ===

Ometto's path to control of the family business was neither smooth nor peaceful. When he first became involved in the sugar operations, the enterprise was divided among seven siblings with competing visions for its future.

For approximately a decade, Rubens engaged in legal battles with family members to consolidate control of what would become Cosan. These disputes were bitter and protracted, reflecting both the value of the assets at stake and the deep personal divisions within the family.

His combativeness during this period earned him the nickname "o trator" (the tractor)—a reference to his relentless determination and willingness to fight until he achieved his objectives. When he finally emerged victorious, he had full control of a business that, while debt-ridden, possessed the potential for transformation.

=== Building Cosan ===

Taking over an indebted family enterprise, Ometto set about transforming it into a modern, efficient industrial powerhouse. His strategy combined operational excellence, vertical integration, and access to capital markets.

'''Public listing (2005)''': In a groundbreaking move for the Brazilian sugar industry, Ometto took Cosan public on the São Paulo stock exchange in 2005. He was the first sugar mill owner to list a company on the exchange, opening access to capital that would fund aggressive expansion.

'''Acquisitions''': Using the capital raised through public markets, Cosan acquired numerous sugar mills and ethanol plants throughout São Paulo state and beyond, consolidating a fragmented industry.

'''Vertical integration''': The company developed comprehensive logistics capabilities, including railroads and ports, to control the entire supply chain from sugarcane field to export terminal.

'''First ethanol billionaire (2007)''': By 2007, the growth of Cosan and rising global interest in biofuels made Ometto the world's first ethanol billionaire—a title that captured the remarkable transformation of a regional sugar business into a global energy player.

=== Raízen joint venture (2011) ===

The defining transaction of Ometto's career came in 2011 when Cosan formed Raízen, a joint venture with Shell, one of the world's largest oil companies.

The partnership combined:
* Cosan's expertise in sugarcane cultivation and ethanol production
* Shell's global fuel distribution network and retail operations
* Shell's capital and technical capabilities

Raízen became one of the world's largest biofuel producers, operating sugar mills, ethanol plants, and an extensive network of fuel stations across Brazil. The joint venture validated Ometto's vision of Brazilian ethanol as a global energy commodity.

Ometto serves as chairman of Raízen, maintaining significant influence over the venture's strategic direction.

=== Diversification and expansion ===

Under Ometto's leadership, Cosan has diversified far beyond its sugarcane origins:

'''Compass (natural gas)''': Cosan controls Compass, one of Brazil's largest natural gas distributors, including Comgás, which serves the greater São Paulo metropolitan area.

'''Moove (lubricants)''': The company owns Moove, a significant lubricants manufacturer and distributor operating in Latin America and Europe.

'''Rumo (logistics)''': Cosan holds a major stake in Rumo, one of Brazil's largest railroad operators, providing critical infrastructure for agricultural commodity exports.

'''Vale investment (2022)''': In a bold move, Cosan acquired a 4.9% stake in Vale, Brazil's mining giant and the world's largest iron ore producer. However, this investment has proven troubled, with Vale's share price declining significantly and contributing to Cosan's current financial pressures.

== Controversies ==

=== Family litigation ===

Ometto's decade-long legal battle against his own family to gain control of Cosan remains one of the most significant episodes in his career. The disputes were bitter enough to earn him his "tractor" nickname and demonstrated a willingness to pursue conflict when he believed he was in the right.

The family business was originally divided among seven siblings, and the process of consolidation involved protracted court battles that permanently altered family relationships.

=== Government relations ===

Despite having financially supported President Lula's campaign, Ometto has found himself at odds with the Brazilian government over fiscal policy.

Points of friction have included:
* Tax increases on fuels and ethanol
* Review of ethanol subsidies
* New taxes that could impact Cosan's businesses

Ometto has publicly criticized fiscal policies he considers harmful to the energy sector, straining relations with Brasília at a time when Cosan needs favorable government relationships for regulatory approvals and infrastructure projects.

=== Financial crisis (2024–2025) ===

Cosan is currently experiencing significant financial stress, described as the most delicate transition since Ometto assumed control:

'''Debt burden''': The company carries approximately R$17.5 billion (roughly US$3.5 billion) in debt, accumulated through aggressive expansion and the troubled Vale investment.

'''Vale investment losses''': The acquisition of a 4.9% stake in Vale has resulted in substantial paper losses as the mining company's shares have declined, adding to Cosan's financial pressures.

'''Dilution of control''': To address the debt crisis, Cosan has been negotiating the entry of new partners, including BTG Pactual and Perfin. Under proposed arrangements, Ometto's economic stake would be diluted from 36% to approximately 21%, though he would retain voting control through his holding company Aguassanta.

'''Bridge financing''': In 2024-2025, Ometto has been negotiating personal loans of approximately US$141 million from Banco Bradesco to maintain his control position in Cosan, highlighting the strain on his personal finances.

== Personal life ==

=== Family ===

Rubens Ometto Silveira Mello is married, though his wife's name is not publicly disclosed. They have two daughters, neither of whom currently participates in Cosan's management.

In interviews, Ometto has stated that he does not insist his family work in the business, suggesting uncertainty about succession planning. His grandchildren are still young, leaving the question of generational transition unresolved.

=== Brother's death ===

On September 14, 2021, Ometto's brother Celso Silveira Mello Filho died in a tragic plane crash near Piracicaba. The King Air 360 turboprop aircraft crashed into a eucalyptus plantation approximately 15 seconds after takeoff.

The accident killed seven people:
* Celso Silveira Mello Filho (73)
* His wife Maria Luiza Meneghel (71)
* Their three children: Celso (46), Camila (48), and Fernando (46)
* The pilot and co-pilot

Celso had been a shareholder in Cosan and was involved in agribusiness through CSM Agropecuária. He was also a former president of XV de Piracicaba football club and a three-time Brazilian autocross champion who continued racing past age 70.

=== Personal interests ===

Ometto is a licensed pilot who enjoys flying airplanes—an interest that adds poignancy to his brother's death in an aviation accident. He is also a collector of classic cars.

Despite his wealth, he has maintained residence on the family farm in Piracicaba, maintaining connection to the agricultural roots of his fortune.

=== Philanthropy ===

Ometto has donated millions of dollars to charitable causes, with particular focus on:
* Education initiatives
* Healthcare facilities
* Environmental conservation, particularly sustainable farming practices

His connection to sustainability stems from both the agricultural origins of his business and Cosan's investments in renewable energy through ethanol and biofuels.

He supports the Amigos do Guri project, which promotes music education in São Paulo state.

== Recognition ==

Ometto has received numerous awards recognizing his contributions to Brazilian industry:

* '''Entrepreneur of the Year''' (2010) – Dinheiro magazine
* '''Global Ethanol Leader of the Year''' (2012) – Renewable Fuels Association
* '''Person of the Year''' (2013) – Brazil-UK Chamber of Commerce, London
* '''Man of the Year''' (2014) – Brazil-United States Chamber of Commerce, New York
* '''Ferroviário of the Year''' (2016) – Revista Ferroviária (for Rumo railroad contributions)

== Net worth ==

As of 2024, Rubens Ometto Silveira Mello's net worth is estimated at approximately US$1.45 billion, though this figure has fluctuated significantly:

* '''2007''': Became the world's first ethanol billionaire
* '''Peak years''': Net worth reportedly exceeded US$5 billion during commodity booms
* '''2024''': Estimated at US$1.45 billion, reflecting Cosan's financial challenges and Vale investment losses

The decline reflects both market conditions affecting Cosan's stock price and the company's significant debt burden, which has required Ometto to seek personal financing to maintain his control position.

== Legacy ==

Rubens Ometto Silveira Mello's legacy in Brazilian business encompasses several dimensions:

'''Ethanol pioneer''': He demonstrated that Brazilian ethanol could be a globally competitive energy source, creating the template for biofuel companies worldwide.

'''Capital markets innovation''': His decision to take Cosan public opened new financing possibilities for the agricultural sector and transformed expectations about how traditional industries could access capital.

'''Shell partnership''': The Raízen joint venture brought one of the world's largest oil companies into partnership with Brazilian biofuels, validating the industry on a global scale.

'''Combative leadership''': His "tractor" approach—aggressive, uncompromising, and focused on victory—represents a distinctive Brazilian business style that has produced both remarkable successes and significant conflicts.

'''Succession uncertainty''': With daughters uninvolved in management and grandchildren too young to take over, questions about Cosan's long-term leadership remain unresolved.
