A CUF is created in Lisbon

In 1865, Companhia União Fabril - CUF is created, with a share capital of 200 contos de reis (Portuguese currency at the time, approximately 1000 Euro). This is the date when CUF is granted its operation license to manufacture soap, stearin and vegetable oil.

Alfredo da Silva presides CUF's destiny

Alfredo da Silva, stockholder of Companhia Aliança Fabril (CEF), promotes the company's merger with CUF and begins manufacturing fertilizers on a large scale. This is also the date when Fábrica Sol, located in Avenida 24 de Julho, in Lisbon, joins the CUF patrimony.

CUF factories open in Barreiro

Alfredo da Silva chooses Barreiro to continue CUF's strong expansion rhythm. On September 19th 1908 inaugurates the first factory in the small fishing town of Lavradio and kicks off acids production, turning oil into olive pomace oil to manufacture soap. Factories employ approximately 100 workers. Also in 1908, the construction activities of Bairro Operário (Workers Quarter) begin.

What the country doesn’t have, CUF creates

n the 30s, CUF owns factories in Lisbon, Barreiro, Alferrarede, Soure, Canas de Senhorim and Mirandela, and employs 16 thousand people. The company's motto, created by Alfredo da Silva, was: "What the country lacks... CUF creates''. 

And this motto was confirmed by CUF's evolution, which gradually added fields to its activities. After beginning operation in Barreiro industrial complex, the first sulphuric acid and superphosphates factory is commissioned, to produce fertilizers. The growth cycle happens in five large production segments: 

Organic chemistry: oil refining, olive oil, soap, flour and feed;
Inorganic chemistry: acids manufacture; 
Metallurgy: copper, lead, gold and silver, as well as pyrite ash treatment; 
Metalworking: with iron, brass and special steels workshops for the sulphuric acid industry. 
Textiles: first with fertilizer packaging, later expanded to fabrics manufacture.

CUF represents 5% of the national GDP

In the 70s CUF is at its height. With over one hundred companies, more than one thousand different products, 110 thousand employees, in all representing 5% of the national Gross Domestic Product, CUF is the largest economic group in Portuguese history.

CUF is nationalised and extinct

In 1975, the largest private corporate group in Portugal (CUF) is nationalised and extinct. Only in 1997, already acquired by Grupo José de Mello, would it return to using the name CUF.

The José de Mello Group returns to the Chemical field.

By the end of the 70s the holding company "José de Mello" is created, with some of former CUF owners as stockholders. The group's re-entry in the chemical industry occurs with the purchase of Uniteca, a chlorine and alkali production company.

CUF brand returns to the industry

The José de Mello Group gains control over the chemical industrial group Quimigal, completely restructures it, and goes back to using the name CUF.

CUF's corporate image change

In 2005, CUF Group kicks off the corporate restructuring process aiming to focus on its core business: chemicals and fertilizers. It also takes the time to refresh and update its corporate image.

New challenge: double the capacity in Estarreja

In 2006, CUF sets off the process to expand its facilities in the Estarreja Chemical Centre, which incorporates the manufacture of chlorine, aniline and byproducts. Expanding the factories, resorting to the latest technologies, ensures greater energy efficiency and widely strengthens CUF's productive capacity.

The preparations for the celebration of the centenary of CUF’s presence in Barreiro begin

On February 27, 2007, João de Mello, CUF’s President, participates in the public presentation of the centenary celebration of the CUF presence in Barreiro – this date will be celebrated the following year. Competitions, exhibitions, book publishing, an international conference and other initiatives, in the scientific and cultural spheres, are part of the Centennial Commemorative Program of CUF in Barreiro.

Fertilizers sale and celebration of CUF's one hundredth anniversary in Barreiro

In 2008, CUF sells the fertilizer business and concentrates its full resources on the chemical industry, focusing on the strategic goal of becoming one of the best in the chemical groups in the Iberian Peninsula. On the same year, CUF actively participates in a comprehensive one hundredth anniversary programme in Barreiro, which included directing a documentary, repairing old films, editing stamps and books, competitions, exhibits, and an international conference.

Inauguration of new factories in Estarreja

On 8th July 2009, CUF publicly presents the completion of the Estarreja Chemical Complex, developed in the scope of a National Interest Project (Projecto de Interesse Nacional - PIN) – an important work that's a landmark for national economy and for the region's development. CUF invests 125 million Euro in this project and doubles its aniline production capacity to 200 thousand tons a year, of which 60% are to be consumed by its partner, DOW. The completion of this expansion positions CUF as one of the five first chemical field companies to operate in the Iberian Peninsula and Grupo José de Mello as one of the largest groups in Europe having their own technology.

Inauguration of the first nanomaterials factory in Coimbra

On 7th September, attended by the President of the Republic, Aníbal Cavaco Silva, CUF inaugurated the new industrial unit of Innovnano - the first national nanomaterials factory. Innovnano's new plant will produce nanomaterials, through a process that's unique in the world, already patented, with application in several industries, such as energy production and storage, aeronautics, electronics, or even the structural ceramic industry. The plant counts on an international network of technological partners that participate in the development of new products and solutions, aiming for entering new markets in the future.
