1865
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). This is the date when CUF is granted its license to manufacture soap, stearin and vegetable oil.

1898
Alfredo da Silva presides CUF's destiny

Alfredo da Silva, stockholder of the Companhia Aliança Fabril. 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 the 24 de Julho Avenue, in Lisbon, joins the CUF ranks.

1908
CUF factories open in Barreiro

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

What the country doesn’t have, CUF creates

In the 30s, CUF owns factories in Lisbon, Barreiro, Alferrarede, Soure, Canas de Senhorim and Mirandela, and employs 16,000 people. The company's motto, created by Alfredo da Silva, is: "What the country doesn’t have... CUF creates''

And this motto is confirmed by CUF's evolution, which gradually adds fields to its activities. After beginning operation in the 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 animal feed;
Inorganic chemistry: acids manufacture; 
Metallurgy: copper, lead, gold and silver, as well as pyrite ash treatment; 
Metalworking: ironworks, brass and special steels workshops for the sulphuric acid industry;
Textiles: first with fertilizer packaging, later expanded to fabrics manufacture.

1970
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.

1980
The José de Mello Group returns to the Chemical sector.

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 chlor-alkali production company.

New challenge: doubling 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 by-products. Expanding the factories, with the latest technologies, ensures greater energy efficiency and widely strengthens CUF's productive capacity.

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) – an important work that's a landmark for national economy and for the region's development. CUF invests 125 million euros in this project and doubles its aniline production capacity to 200 thousand tons a year, of which 60% are to be used by its partner, DOW. The completion of this expansion positions CUF as one of the five first chemical companies to operate in the Iberian Peninsula and Grupo José de Mello as one of the largest groups in Europe – with proprietary technology.

2012
Inauguration of the first nanomaterials factory in Coimbra

On 7th September, with the presence of the President of the Republic, Aníbal Cavaco Silva, CUF inaugurates the new Innovnano industrial unit – the first national nanomaterials factory. Innovnano's new plant will produce nanomaterials, through a unique process, already patented, that have applications in several industries, such as energy production and storage, aeronautics, electronics, and 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 new markets in the near future.
